Owlet Smart Sock Frequently Asked Questions

April 1, 2020

We recently asked our Facebook and Instagram followers to weigh in and share their top Owlet Smart Sock questions. As promised, here are the answers to many of your Owlet frequently asked questions.

Q: About how long does it take the Sock to charge?

A: The Owlet Smart Sock has an 16-hour battery life. The Sock is powered by a coin cell rechargeable battery (like what you’ll find in your wrist watch) needs to be charged daily. The Sock takes about four hours to charge, so you can typically achieve a full charge in between naps. Many Owlet parents make it a practice to plug the Sock in whenever it’s not in use.

Q: Does the Sock adjust as the baby’s foot grows?

A: The Owlet Smart Sock includes three fabric sock sizes, so you can just pop the Sock electronics out of one fabric sock and into the next size up. Each fabric sock has velcro on it to help adjust and secure it to baby’s foot.

This guide helps explain how to get a good Sock fit, which is crucial to getting proper readings and preventing false notifications.


The Smart Sock is the first baby monitor to track your baby’s oxygen level and heart rate—the best indication of baby’s health—while they sleep.

Q: Can we set another oxygen level as the minimum?

A: No, the notification zones are preset and cannot be changed.


Q: Is it possible to have a false notification for low heart rate? 

A: Improper Sock fit can lead to false notifications. To ensure a proper Sock fit, check out our fit guide here.

Another tip: when you get the baby out of the crib for a feeding or to change their diaper in the middle of the night, remember to turn off the Base Station, as the motion from rocking in a chair or your body blocking the signal can cause improper readings and false notifications. The Owlet Smart Sock is designed to be used when the baby is sleeping, alone, in his or her own sleep space (e.g., crib, bassinet, etc.).


Q: Does the Sock Sensor turn off?

A: You don’t need to turn the Sock off, but if you’d like to (if you’ll be traveling and want to save the sock’s battery), follow these instructions.


Q: Is the Sock portable so I can send it to Grandma’s or babysitter’s house when my baby will be napping?

A: Yes, the Owlet Smart Sock is portable. The Base Station and Sock Sensor connect via Bluetooth, so even if Grandma doesn’t have WiFi, the monitor can still be used with the Base Station as the notification system. If you want to connect the Base Station to Grandma’s WiFi so you can view live heart rate and oxygen level on the app, follow these instructions to add a new WiFi network.


Q: Can my baby still wear footie pajamas or does the foot need to be uncovered?

A: Yes, your baby can wear footie PJs (or even another sock) over the Smart Sock. It’s low profile so it can fit nicely under PJs.


Q: How does the payment plan option work?

A: Owlet has partnered with a company called Affirm to offer payment plans. So instead of paying the full amount upfront and at once, Affirm allows you to make payments (payment amounts, interest rates and terms vary by applicant). You do NOT have to wait to receive your Owlet Smart Sock until after your payments are finished. When you purchase and set up a payment plan with Affirm, your order will process and ship as if you paid in full. For more details and answers to even more Affirm FAQs, click here. To pay for your Owlet order with Affirm, select ‘Affirm’ at checkout.

Is done with the Owlet** can i give



When my child is done with the hour that can I give it to another mother and have them program their own child into it?


Hi Saige, it sounds like the movement from the SNOO is throwing off the Sock’s ability to track sleep quality. Any movement can interfere with readings so we do not recommend using them together.


Hi there! It sounds like your data is just lagging with uploading. Try force closing the app on all devices and unplug the base station for a few minutes.



Hello, we have been using the sock for about 4 months and love it. Last night was the first night where there are gaps in the middle of the night with no readings when you review the baby’s night sleep in the graph overview. This happened multiple times. Do we know what would cause this and how to correct it?



Since I have gotten the SNOO my owlet sleep pattern seems to be all over the place. Before my daughter was sleeping soundly with a general “great” sleep quality. Now the owlet says she is sleeping poorly with several wakes in-between feedings,but the SNOO says she is sleeping soundly. Is this a glitch? Should I no longer look at the owlet for sleep quality?


Hi Natalie! The app will show the live readings but the base station will always send you a notification. You can be anywhere with an internet connection and have access to the live readings.

If you’d like to give access to the app, just share the login you created upon set up!



If someone is watching the baby overnight, do they need the Owlet app? Or would they just use the base station to know if there are any problems? Will I still receive notifications through the app if I am not in close proximity to the base station? Lastly, if they do want to get the app so they can see all the details, do they create their own account or link in through mine?


Hi there is interest. Seems like a perfect solution to have white noise or lullaby since the cam is already near the baby. Saves buying and finding room for another device



can the baby wear the sock to the store or anywhere outside the home without the base and still get notified?


Hi! Our team would be happy to assist you with this. Please chat in with our team via the Owlet app, or try calling our team at 844-334-5330. We hope to hear from you soon!



My owlet is plugged in all day, white solid ring. Then it is low battery at night when I put it on my girl, this has happened the past 2 nights. It just won’t charge. Help!


Hey Emily, you will need a WiFi connection to use the app and view the live readings on your phone but you can still receive notifications via the base station if you don’t have WiFi.

If the battery on the sensor gets low, you’ll receive a blue notification on the base station. You can also keep an eye on the sensor while it’s charging. The dome on the sock will pulse green while it’s charging and be solid green when it’s complete.



Hello! Recently bought this for my month old. We do not currently have WiFi. Can I not use the app at all without WiFi? Can I use the device at all?

Also, if I can’t use the app, which is very inconvenient, how do I know when the base and sock are charged and when they are running with low battery?

Thank you!


Hi Daniel, Unfortunately due to firewalls in place on most hotel WiFi, the Owlet Base Station typically cannot be connected via WiFi (meaning you will be unable to use the app). However, you can still rest assured that the Base Station and Smart Sock will continue to function without interruption, with the Base Station as the primary notification center.



How can I connect to a hotel WiFi where you need to sign in on a webpage?


Hey Jasmyn, use the chat feature in the Owlet app and our team will look into this for you!


Jasmyn N Walker

My sock is saying that it is charging when I plug it in as the base station goes solid white, but the past 2 nights as soon as I take it off the charger after over 12 hours of charging it says low battery and tonight it said that it was completely dead with 0 charge… why is this happening???


Hi Kelly, thanks so much for reaching out to us. If you believe that these are false red notifications, it’s most likely due to the sock fit or placement (this can happen when you’re little one is growing out of the sock). Our customer care team would be happy to look at this for you. You can take pictures of the sock on your little one and send them to our team via the chat feature in the Owlet app.



Hello, my son has been using owlet for almost a year because of his reactive asthma. It has saved his life by alerting me of low oxygen levels throughout the night 6x which resulted in hospitalizations and countless others which I was able to resolve at home with his rescue medication. Lately I am receiving low oxygen alarms nightly but he appears fine. Is the sock getting too small? I’ve never had a problem with the sock fit prior to the past week (not to say it’s not a possibility). If yes is Owlet working on a sock for toddlers that parents can use? I understand Owlet is for presentation of SIDS which is why it’s for 0-18months but I’m sure parents use it for other health issues such as asthma or cardio. I have been searching for another device to use after he outgrows the baby sock so I can help him through the night and still get sleep myself but he’s a small guy and most devices are finger devices which wouldn’t fit him for some time I’m afraid.


Hey Corey, call our team at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST and they’ll help you out.



My sock doesn’t charge anymore unless I am personally holding the connections together just right. This is not realistic to do for hours each day.


Hi Jessica, they should just need to set up their own account and add the Smart Sock. If they need any help, just have them give our team a call at (844) 334-5330 for assistance.



Hello! We’re done using our Owlet with our daughter & we’re giving it to a family member. How Should we go about resetting everything for them to use it for their newborn? Thank you


Hi Brad, it depends on how long you previously used the sock but if the battery is low, it will typically need to charge for about 4 hours.



How long does it take the sock to charge? I see this question in the FAQ but nowhere in the paragraph answer does it actually answer the question.


Definitely give our team a call at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST and they’ll look into this for you!



Hello, I bought my sock in February and it has worked perfectly until the last week. We plug it in but it won’t connect to charge and then sometimes the white light as if it is charging is on all day, but then when I go to put it on my son and turn it on the battery is at 30%. Can our sock be fixed or sent a new one?


Hi Stephen, the Cam doesn’t have sound or motion notifications but they will be available in the coming months.


Stephen Robbins

Hello, I have the smart sock 2 and cam, do these also work like traditional monitors and alert you when baby is crying or cooing


Hey Anna! Reach out to tech support at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST and they’ll look into this for you!

Tommy J. Badeaux

My kid’s sock randomly turns off in the middle on the night and gives a blue light notification. This has happened every night since your servers were down last week.

The product has not even been used a month and is charged daily. How do I fix this before I ask for a return or refund?


My daughters sock randomly stopped charging how do I fix this?



We’re still waiting for a reply email. We are very frustrated with the socks readings. It just has dashes and will not ready, we have tried EVERYTHING that is suggested and constantly have sock placement alarms. We didnt have any issue the first week but are having a ton since the app went down and is now back up. We don’t know what else to do or if the sock monitor is defective.



My sock won’t charge. I have reset it multiple times.



My sock wont charge more then 28% even after 15 hours of charging. I just bought this not even 3 weeks ago. I feel for a product that’s 300 dollars shouldn’t be this defective. Will only last 4 to 5 hours at night before it starts beeping that the battery died. Very irritating had such high Hope’s for this.



Still pregnant, purchased an owlet from a consignment store. plug the charger in and charged the sensor all night. when we took it off the charger in the morning it sent a message to our phones shortly after. is this because it is not picking up data from a baby, or because the sensor is not accepting a charge?


Sabrina Scardina

Hi! I’ll be traveling Friday. Do the sock and base need to be packed in my carry on or can they be with our checked luggage?


Hi! There is not a white noise feature.


Hey Moriah! Our team would be happy to look into this for you. Please connect with Customer Care at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST for assistance.



It sometimes takes over 10 minutes for the sock to get a reading on my infant’s foot. I’m just staring at my app forever and it says he’s wiggling when he isn’t. Do I have a defective sock?



Does the camera monitor play white noise for the baby?


Hi Shannon, thanks for reaching out! The notification on your phone should stop once you’ve turned the base station off (either from your phone or by pressing down on the base station) but once the battery has reached a critical level, it will continue to send notifications until it is charged sufficiently.



When the battery level gets low I continuously get notifications. When my baby is asleep I’m not going to wake him up to take off the sock. How can I acknowledge the alarm of low battery then stop the app from continuing to make noise? The base station is turned off.


Hi Annie, the sensor is still turned on during this time but we would recommend turning the base station off during this time to avoid blue notifications or red notifications- these can occur while you’re holding or feeding your baby.



when you get the baby out of the crib for a feeding or to change the diaper in the middle of the night if i turnoff the base station will it conserve battery


Hi Mike, as you know, the Owlet Monitor was designed with different notifications, including notifications for heart rate and oxygen falling outside of range (red), Bluetooth disconnect between the Smart Sock and Base Station (blue) and inability to get a proper reading (yellow). Each one of these readings uses a different algorithm in order to work. For example, when you take the sensor off of your baby, the pulse-oximeter is no longer able to get a reading and a yellow notification sounds. A delay may happen because the pulse-oximeter technology could no longer find the baby’s skin to get a reading. It could be even further delayed if you are holding it or place it on a soft surface because it will sense motion.

However, if the sock had remained on your child and he was asleep and oxygen or heart rate left the preset zones, the pulse oximeter would have notified you immediately as it uses as a different algorithm. We hope this answers your question! Please reach out to our team at contact@owletcare.com if you’d like to learn more from our team!


Hi Alexis, the battery life can depend on a few factors like the distance between the sensor and the base station. Feel free to reach out to our technical support team at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST if you’d like them to look into this for you!



When I take off my owlet sock it takes more than two minutes to register that it’s misplaced and then the alarm goes off.

I’m worried that if there’s an oxygen or heartbeat reading going below the recommended allowance that it’ll take way too long for it to go off and it’ll be too late.



Alexis Cannon

We charge our Smart Sock every morning as soon as we take it off our baby. She’s 10 months old, and for the last couple months we’ve noticed the battery is low after only 12 hours. Is there a way to fix this?


Hi Blanca, thank you for reaching out! We don’t have any smaller sock sizes available but some preemie parents have had success by placing a regular sock over the top to keep the sensor in place. This helps until their little one grows a little more. We hope this helps!


Blanca -NICU mom

I have a preemie baby, and the smallest sock is too big. She weighs 4lbs. Do you have any options available? We brought her home from NICU last Thursday and she had respiratory issues so we feel that this would give us more peace of mind and allow us to sleep a bit at night without waking up every chance we get to make sure she is breathing properly. But the smallest sock is too big for her, it keeps falling off. What do you recommend? Do you have any preemie socks coming out soon?


Hi Kourtney! The thresholds are as follows- heart rate: 60-220 bpm and oxygen: 80-100%.


Hi Millie, the sensor is usually okay if it’s not submerged in liquid. You can wipe the sensor down with a damp towel and allow it to air dry. You can then plug it in and it should be good to go if it charges! You can also hand wash the fabric sock with a mild detergent and let it air dry. Hope that helps!



How would I know if it harmed it?



I was changing my baby boy’s diaper and he peed everywhere! Some of it got on the sock. I’m not sure how much actually soaked through the fabric but do you think this can harm it?



What is the parameters set on the owlet sock for low/high for heart rate. Also what is low number on the sock for the oxygen saturation that it will alert that the oxygen level is low?


Hi Whitney, please reach out to our team at contact@owletcare.com and they’ll take a look into this for you.


Hi Alex, it looks like this happened after our server maintenance. You may want to power cycle. 1- Force close the app 2- Unplug the base station 3- Wait 4-5 minutes and plug everything back in.


Hi Jon, that’s definitely odd! Please reach out to our team at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST so they can look into this for you.


Hi Lexie, flying wouldn’t affect how the sensor charges. Don’t hesitate to reach out to our team at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST and they’ll take a look into this for you!



My owlet sock it acting up. I put the sock on perfectly but the station keeps blinking yellow saying to place it correctly. I watched the videos over and over again and I am 100 percent sure I’m fiting the sock perfectly. I even tried both feet and other sizes as well but the station still is blinking yellow and hasn’t had any reading since Friday which is the day I unboxed it brand new.



We are trying to use our smart sock with our newborn but it always says he’s too wiggly to read it. Tonight he was sleeping still on our couch & our sock wouldn’t not read. Is our smart sock defective?


Hey Chelsie! Yes, the base station must be plugged in for it to work.


Hi Katherine! That would definitely be frustrating! If you haven’t yet, give us a call at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST and our team will take a look into this for you.



The last two nights I’ve been getting 5-7 blue notifications. I’ve taken the sock off my daughter and plugged it back in to make sure it’s connected and it is. Full battery as well. The base has been in the same spot for six months with little problem. Sometimes the blue notifications go off and then immediately switch back to green. My baby sleeps through the night but my owlet doesn’t! Haha! Any advice would be appreciated.


Lexie Rendell

Why does everytime I travel (fly) with my owlet in my suitcase do I have issues charging it after? My owlet worked great wednesday night, flew on Thursday and now (Thursday night and all day Friday) I can’t get it to charge. I just replaced it in May for the same issue. There are no disclaimers saying you can’t fly with it.



I am having a problem with my owlet. I am using the owlet care app and it tracked sleep fine the first few nights, even after the night feeding. The last two nights, the sock stopped tracking after she went back to sleep after her night feedings. The sock is on right and I haven’t gotten any displacement alerts. How can I fix this?


Chelsie Voss

Does the base station have to be plugged in to work?


Hi Helen, it’s possible that the data is just experiencing a lag with uploading into History. Try force closing the app and the unplugging your base station for a few minutes and see if that helps!


Hi Kendra, as you know, the Owlet Smart Sock thresholds are preset and are not adjustable. The Owlet Smart Sock is not a medical device and intended for use to provide peace of mind to parents. Adjustable thresholds are prescribed by physicians and enabled by healthcare professionals working in medical devices (or pulse oximeters) for special conditions.



Why are the monitor limits fixed and unable to be changed by the parent? This is the one thing I really do not like about the product. The lower limits for both the oxygen and heart rate are quite a bit lower than they should be for my baby. If you allowed the limits to be changed, age could be taken into account and also if there are other conditions to take into consideration for the baby.



My smart sock has been working great for 2 months and I sleep much better knowing my baby is wearing it! I also enjoy the sleep tracking function, however last night it reported that there was only 6 hours of night sleep till 00:15 and then 2 daytime naps at 0130 and 0415?
There seems to be missing data in between them too. This obviously isn’t the case and in fact my baby slept from 1815 till 0445 but the sock didn’t reflect this and no notification has been recorded.
Can you help?


Hey Courtney, you can charge it this way but make sure that you aren’t using a quick charging micro USB. You may also want to call Customer Care at (844) 334-5330, Monday-Sunday from 7 am – 10 pm, MST so they can look into this for you.



Hi! Is it possible to charge my smart sock into my wall charger to charge, instead of plugging it into the base station? I have trouble getting it to charge through the base station. Thank you


Hi Sierra, take a few pictures of the sock on your little one and send them to our team via the chat feature in the Owlet app. They’ll help give you tips and suggestions!


Hi Audrey, give Customer Care a call at (844) 334-5330 and they’ll look into this for you asap!



I have tried the medium and large sock for my 14 lb baby and the alarm goes off once or twice a night and she is perfectly fine. We have tried putting it on tighter and looser and nothing works. We cant be waking up every night for nothing. I would’ve loved this product if it didnt do this. How can it be fixed?



I turn the base station on manually before I leave the room. Occasionally, when I go check the app a few hours later, it says the base station is turned off. I will then turn it on via the app and it will get a reading. Again, I will check it a few hr later and it is turned off AGAIN! Why does the base station keep turning off? Is it monitoring my baby?


Hi Tiffany! For multiple children, each one will need their own separate and complete Smart Sock system. You can add multiple Owlet devices all within the same app, though!


Hi Krystal, individual parts are available for purchase. Call Customer Care at (844) 334-5330 and they’ll help get you the right part ordered.


Krystal Allen

Can you buy just the sensor? Ours got wet too and it is not working



Can you add a sock for a second baby? Or do u have to have to have to monitor and to socks


Hey Nick, if you have any questions or concerns, don’t hesitate to reach out to our team at (844) 334-5330. They’d love to look into this for you.


Hi Sara, the sensor is not water-proof and you may need a new one if it entered the charging port. If you have any questions or concerns, don’t hesitate to reach out to our team at (844) 334-5330.



I just spilt water on my sock and sensor. It was minimal but both did get water. I dried it off immediately. Would I need to think about getting new sensor? Could it hurt my baby now that it has been wet?



When the camera is plugged in, why is the adapter piece where inserted make noise?? Is this supposed to be this way?


Hi! Just give Customer Care a call at (844) 334-5330 and they’ll look right into this for you!



Only been using ours for just shy of one year and now the base station and both our phones go off, waking us up with a notification every morning at 4:30 a.m. saying low battery when it was fully charged and only taken off the charger when put on the baby at bedtime (7:30-8).

It hasn’t always been this way so clearly the battery life has deteriorated. We can’t seem to edit that notification and we can’t keep getting woken up earlier and earlier every morning while this battery slowly kills itself, so the product is basically useless to us after a year.


You can play music through the two-way audio but there’s not a way to do this directly from the app. This isn’t an available feature but we can definitely let our team know there’s interest in this!


Hi Giorgia, thanks so much for reaching out. The Owlet Smart Sock thresholds are preset and are not adjustable, similar to other consumer wellness products, like smart watches. These thresholds are in place for a few reasons, one being that a baby can quickly desat and come right back up. This helps avoid false notifications due to fluctuations.



Hi there,
We had a mistaken low oxygen alarm one night and we were in a bit of a panic so called the hospital just in case. Turned out the sock wasn’t in the ideal placement so it thought the oxygen was low. When speaking to the nurse I told her that the oxygen was at 80% she said at this stage you would be calling emergency services/driving to a hospital as it is very dangerous. Could it be something to look into to re-set the “normal” range to say 90%-100% oxygen, instead of all the way down to 80%, when it might be too late? Thanks so much for your consideration. We love the Owlet and are so grateful this technology is available to us. 🙂


Jeremiah Diamond

Can you play music like lullabies or white noise for my baby through the speaker on the camera? If not, is that something you can program into it?


Hi Ashley, thanks for reaching out. Anytime you place the sensor on a soft surface or hold it, the sensor will sense motion and delay the time in which you receive a yellow notification. This is because it uses motion to help determine if the sock is misplaced or has fallen off. Additionally, our team would love to look into the excessive notifications you’ve been experiencing for you if you can give them a call at (844) 334-5330. We hope to get everything running smoothly for you soon!


Ashley V

My owlet is sending out red and yellow notifications like crazy. The low oxygen has gone off in the middle of the night 3 times in the past two weeks (which is a lot!) and immediately after checking on the baby the oxygen levels are back at 98/100%. The placement alarm goes off multiple times a week while baby is sleeping, randomly, without movement! We’ve been using the owlet for 7 months without these issues so I am confident it is not due to poor placement. On my phone/app when this happens I receive anywhere from 10-35 alerts (like a friend blowing up your phone… Notifications like crazy!!) in about 15seconds. Also when we remove the sock and place it on the bed in the mornings I wait for the song to alert misplacement of sock and it sometimes takes up to 5 minutes to recognize it is not on the baby! This makes me worry that it’s not functioning properly.


Hi Emily, we don’t have any larger sizes but the last sock was designed to fit from 4-18 months.



Hi, we have an owlet. My son is 14 weeks old and already wearing the biggest size sock that came with it, do you sell a bigger one? I don’t think it will last very long. Thank you.


Hi Ryan, please reach out to our team at (844) 334-5330 and they’ll take a look into this for you!


Hi Lindsey, this isn’t an available feature at this time but we can let our team know there’s interest in this!



within the past two weeks our sock doesn’t want to hold a charge. it’s on the charger all day and once we put it on our daughter at night it lasts maybe an hour and we’re notified that the battery is low. how long is this battery supposed to last we’ve had it 3 years now.



Is it possible to turn the base station’s chirp off so that it doesn’t make noise when turning off and on? It is startling my newborn during night time feedings. Thanks!


Hi Louis, this isn’t possible right now but it’s definitely something our team is looking into for the future!


Louis Romano

Is it possible to connect the Owlet System to Alexa or other smart devices to be able to see the video feed from the camera?


Hi Amanda, the yellow notification uses a different algorithm than the red notification. Because the yellow notification uses movement as part of its algorithm, it will not sound if you’re holding it or move it around. Also, make sure to check the sensitivity as this will delay the time in which you receive the yellow notification. Keep in mind that for the red notification, you would receive it the moment that heart rate or oxygen were to leave the preset threshold.


Amanda Orme Inkley

Lately our owlet has not been alarming after we remove it in the morning and we can’t get it plugged in soon enough. It use to always sing at us and tell us difficulty getting reading but it has not done it lately. How do we fix this? I want to know that my owlet will alarm if something does happen!l.


Hi Anna, we’d recommend turning off the base anytime your baby is not sleeping in his or her crib. Holding or feeding your little can contribute to red notification or your body may block the signal which would cause blue notifications.



Do I need to turn the base off when baby wakes up to eat during the night?


Hi Kaylyn, we offer individual parts for purchase. Give our customer care team a call at (844) 334-5330 and they’ll troubleshoot and help you purchase the correct part.


Hey Loni, the thresholds are preset and nonadjustable.


Kaylyn Flores

Our owlet (bought in March 2018) sock sensor won’t charge anymore. Over the last week it started sending notifications of low battery while I was at work and know I plugged it in to charge. I would come home to find it plugged in but the white light on the base station wasn’t on. Now it’s completely dead and doesn’t register with the base station while plugged in. Do I need to buy an entire new Owlet?



Can these ranges be adjusted with the app? I feel that waiting for a heart rate of 60 and O2 of 80% is extremely low in a baby.


Hey Celina, the Smart Sock was not designed to be portable as movement can affect its ability to get a good reading. It works best and is designed to be used when your baby is sleeping in his or her own sleep space like a crib or bassinet.



Does the base need to be connected to the wall? Is there a way to make it portable and use it on the road?


Hi Carrie, you’ll want to connect with tech support at (844) 334-5330 and they’ll look right into this for you!



Battery says it’s low but we have used this for 15 months. Do we need a new battery


It sounds like everything is working correctly. Especially if you’re holding the sensor or place it on a soft surface, it will sense motion and delay the time in which you receive the yellow notification. Keep in mind that the red notification wouldn’t have the same delay as it uses a different algorithm. Additionally, we have seen that feeding, burping, holding baby, changing baby (etc) while the Smart Sock is turned on can contribute to a red notification. Simply turn it off during this time and then back on when your little one is ready to go back to sleep in their crib or bassinet.



Thank you for responding, I have noticed that if we are patting her bum it will give crazy reading ( high heart rate , low oxygen ) right when it we lay her down it regulates , does that sound normal for the sock ? Also , it takes awhile for the monitor to notice the sock is misplaced on her foot , I can take it completely off and it won’t read for awhile
, could I have a malfunctioning sock ??


Hi Peggy, choosing the sock color is a special promotion that’s available from time to time so make sure to keep an eye out!


Hi Sanae, a low battery will not affect the oxygen reading but it’s possible the sock was moved out of place if your little one was awake.


Hey Tiffany, before purchasing any new parts, we’d recommend contacting technical support at (844) 334-5330 so they can ensure that’s the part you need. You should only need just the part that’s not working.


Peggy Byrd

Can I order a pink sock instead of the blue one shown. It does not give me a choice of color when I try to order. I am ordering this for my niece and I thought it was expensive to begin with and was hoping I did not have to order another sock in pink .



I was given a low oxygen reading on my little one , she was awake and fine but I noticed the sock was running low of battery. Can a low battery give a false oxygen reading ?



The Owlet that I have was bought for my baby born in May 2016. I was going to order a new base because the power port is not working. Has anything changed that I would need to buy a new sock or sock sensor?


Hey Brittany, the Smart Sock continuously sends readings to the base station every few seconds.


Brittany Allen

How often does the owlet moniter heart rate and oxygen levels?


Hi Marie, this isn’t covered by the warranty but we do offer individual parts for purchase if you give our team a call at (844) 243-4340. It sounds like you will just need a new sock sensor.


Marie c

Accidentally washed the sock and the sensor was in it. I’ve tried plugging it into the base, but nothing happens. Will we need to buy a whole new sensor? Bought it in early December of 2018.


Hey Meagan, the Owlet Cam needs to be plugged into a power source to function.



Does the owlet cam still work when not plugged in? Can I move it from room to room without moving the wiring?


Hi Dana, the magnets could cause the Smart Sock’s sensor to turn off so we wouldn’t recommend using them if they are near the sensor.


Dana Bryant

My wife and I just purchased some magnetic snap onesies. We were wondering if the magnets might interfere with the sock or the readings.


Hi Alissa, I’d recommend calling into our customer support team at (844) 334-5330 so they can look into this for you!


Hey Nicole, our team would be happy to help ensure everything is working properly for you! Please feel free to reach out at (844) 334-5330 for assistance.


Nicole Laconcha

When i take the owlet off the baby it isnt making the noise to notify me. It makes me think its not working properly.



Is the owlet still monitoring when the app says the base station is off ( but it’s not actually off)?


Hi April, give our tech support team a call at (844) 334-5330 and they’ll look right into this for you!


April Scott

My app has been saying that the sock is off my child. It’s not. We’ve used it for 5 weeks now and the past week it has said this. Is there something I can do to fox this. I really would like to be able to see his stats.


Hi Rachel, call tech support at (844) 334-5330 and they’ll look right into this for you!



Hello my battery is suddenly not holding a charge – even after being on the base station all day. How can I get this fixed?


Hi Cacy, we don’t currently offer any toddler sizes the Smart Sock. The largest size we offer was designed for infants 18 months or around 25 lbs.


Cacy Ramirez

I REALLY want this to fit my toddler! It’s an excellent pulse ox for febrile seizure monitoring! Is the a toddler sock? She’s 2 now


Oh no! The sock sensor is not waterproof and we wouldn’t recommend using it if it’s been submerged in water. Please call the tech support team at (844) 334-5330 and they’ll look into this for you!



So my husband gave our daughter a bath and got the sock completely wet, with the sensor still inside the sock. I separated them when I noticed it and have them both laying out to dry. I was wondering if this will damage the sensor ?


Hi Morgan, call the Owlet Tech Support Team at (844) 334-5330 and they’ll look right into this for you.



My owlet will read everything fine for 10 or 15 minutes and then just stop giving new readings and sound the misplaced alarm but she will be completely still the whole time. This has happened several times she is in the smallest sock and the next size up is still to big. I lost a son to SIDS 2 years ago so I really depend on this to have peace of mind…


Hi Shawna, it does sound like your little one is growing out of the sock. The shape of your little one’s foot as it has grown larger could impact the sensor’s ability to get a good reading. The recommended weight limit is a good measurement of knowing if the sensor fit correctly on your little one to get a good reading. If you’d like to make sure, don’t hesitate to take a few pictures of the sock fit on your little one and send them to our team via the chat feature in the Owlet app!



Two nights ago my husband and I were woken to 4 low oxygen alarms throughout the night. Every time we went in and checked him, he was fine and annoyed with us. Our son is 16.5 months and 28 lbs. We realize he is over the recommended use weight, but I can’t help still using it for peace of mind at night. I usually always check his levels on my phone before I go to sleep, and did notice they were in the lower 90s/high 80s, but wasn’t concerned. I took him to the doctor the following morning and they checked his oxygen levels twice, with readings always above 98%. Based on how the light sensor works to take the reading, could his foot be becoming to fat/big to obtain proper readings for the size of the foot monitor? What is the reasoning behind the 25lb limit for use?



Hi Jeana, connect with the Owlet Technical support team at (844) 334-5330 or through the chat feature in the Owlet app and they’ll look into this for you!



My base station randomly turns off in the middle of the night. What is causing that?


Hi Alfredo, this is not a feature the Owlet Smart Sock provides.



Can the owlet 2 detect when the baby rolls over on their stomach?


Hi! The smallest sock size was designed for infants 6-8 lbs.



I was wondering what is the minimum weight limit of your baby for the sock to fit?


Hi Tessa, the red notification will sound the moment heart rate or oxygen level the preset thresholds. Keep in mind that not only will the app send you this notification but your base station will too!



How quickly will owlet turn red when something is wrong? Whenever I check the app it takes a good 20-30sec to get readings.


Hi Cassea, Connected Care does use algorithms based on heart rate, oxygen and movement to determine sleep. The movement caused by your little one moving his legs could be interfering with its ability to give a correct estimate of the amount of sleep your little one is actually receiving.



My LO just moved to his crib two days ago he moves his feet a bunch at night now with all the space he has. The connected care is saying he’s getting only around 3-4 hours of sleep at night and up for 6. I have a monitor also and wake up when he’s ready to eat. I am almost certain he is asleep when I’m sleeping because he is quiet but moves legs, could him moving his legs throw off the sleep segment?


Hi Kelley, our technical support team can definitely look into this for you if you give them a call at (844) 334-5330.



Everynight from 1am on one of our owlets goes off. The sock fit is right, it’s on tight, foot isn’t cold, it’s less than 100 feet from baby. But every night it goes off. We reset it and turn it back on. And it goes off. We tried turning baby monitor off and it didn’t happen, but we kind of need the monitor. Can there be Bluetooth interference causing false yellow alarms? What can we do?


We don’t have a release date yet but we will definitely announce it when it’s ready!


Hollie Bradshaw

When will it be available to Android Users? It’s October now.


Hi Megan, if your base station was disconnected from WiFi during that time, no information will show. If it was connected, send our team an email to subscriptions@owletcare.com and our team will look into this for you!



Last night on connected care there is just no data between 9 and 12. There is recorded sleep before and after that time. It also doesn’t even say awake ts just blank. I never got an alarm either. Everything’s ok this morning but Did it just stop working for 3 hours?


Hi Anita, our technical support team would love to look into this for you if you give them a call at (844) 334-5330!



I’m having issues with the owlets battery life. I’ve only had my owlet for 6 months and It’s definitely not lasting the 18 hours between charging as your website states. At most It’s lasting 11 hours and every week it’s staying charged less and less. We can barely make it through the night at this point before I get a low battery notice.


Hi Amanda, this could be a lag due to your internet connection. Our tech support team would be happy to look into this for you if you give them a call at (844) 334-5330.



How long should it take the app to get a reading? My app will say “Getting reading…” for what feels like forever before it’ll actually show a live reading. Just want to make sure my sock isn’t faulty.


Hi Jessica, give us a call at (844) 334-5330 and our team will look right into this for you!


Jessica Lohman

I keep getting messages that my base station turned off (clearly its still on). Concerned because this keeps happening and isn’t monitoring. Is it because my base station isnt in a direct clear view with the sock? Thanks!


Yes, it will be available eventually! Our team is working hard to make it available to Android users!



Will Connected Care ever be offered for Android users? I don’t see it in my App Store.


Hi Katrina, thanks for reaching out with your question! Technically, you could use a different power source like a power pack, however, we would not recommend using the Smart Sock in a car as the motion can interfere with its ability to get a good reading.


katrina dills

can the base station be used with a power pack? example long rides or the home power being out.


Hey Josh! If you’d like help, give our team a call at (844) 334-5330 or use the chat feature in the app. If you’re staying at a hotel, it will be very difficult to connect the Owlet Base Station to hotel WiFi because of the firewalls they have in place. It will re-authenticate throughout the night, meaning the app will constantly disconnect and receive “Base Station is disconnected from the Internet” notifications and you’ll have to re-connect it each time. Unfortunately, the Owlet Base Station typically cannot be connected via WiFi (meaning you will be unable to use the app). However, you can still rest assured that the Base Station and Smart Sock will continue to function without interruption, with the Base Station as the primary notification center.



Yes to this! I followed the link to adds new WiFi and it didn’t work. Basically had to start over like it was fresh from the box. Would love some advice please! How do I take this for a weekend trip????



Can you give more info on how to travel with this? We weren’t able to get this to work and support had us completely unregister then reregister the owlet. I didn’t work and then when we got home it was no longer working as usual. A step by step how to travel and set it up without unregistering would be appreciated!


Hi Laura! Thanks for reaching out with your question. Pulse oximeters, including Owlet and pulse oximeters used in the medical community, are very sensitive to movement between the skin and the sensor, as movement can impede the ability to get an accurate reading. This is why we are unable to share a reading with excessive movement (or wiggling). As a company that prides ourselves on innovation, we are always looking at ways to address feedback like this in future iterations.

We would like to ensure everything is working well for you as you shouldn’t get a ‘wiggling’ notification with only slight movement. Please feel free to reach out to our team at (844) 334-5330 or through the chat feature in the app and we’ll look into this for you!



Hi! We recently purchased the owlet for our 2 month old. Any time he moves even slightly it will say “baby is wiggling” which is great. My concern is what if for some reason something is blocking his face or he rolls over and can’t breath but if fighting to get some air. Will the owlet still alert me if his oxygen and heart rate drop dangerously low? I know if I was having trouble breathing I would surely be wiggling to breath again.


When I did a livechat, the rep said 4 hours to charge.


You can absolutely swaddle while using the Owlet Smart Sock. 🙂



Can the sock be worn while the baby is swaddled through the night? We are big on swaddling our babes and we just purchased this. I want to make sure we can do both at the same time.


Hi Paige! The notification for oxygen will sound at 80%. If you’d like an exact number, our additional app called Connected Care shows historical data and other trends. You can learn more about it here: https://owletcare.com/products/connected-care



I had a low oxygen alert went to check the baby & woke him but it was normal when I got in his room how can I check what the level was of that notification?


Hi Alf! The charging time will depend on the amount of time you have used the Smart Sock. However, typically if the battery is low, the sock will need to charge around 4 hours. As this time will vary, we recommend keeping an eye on the dome on the sock. It will blink green while it’s charging and be a solid green color when it’s completely charged. You can also check the battery life on your app!


Alf Smithey

How long does it take the Owlet 2 Sock to charge? you still have yet to give us an answer. i don’t care between naps or the answers where you avoid the question. as in time, how many hours, minutes, seconds.. how long does it take to charge an owlet sock?

“Q: About how long does it take the sock to charge?

A: The Owlet Smart Sock has an 18-hour battery life. The sock is powered by a coin cell rechargeable battery (like what you’ll find in your wrist watch). However, your sock will need to be charged daily. You can typically achieve a full charge in between naps. Many of Owlet parents make it a practice to plug the sock in whenever it’s not in use.“


Hi Claudia! The Owlet shows live readings of heart rate and oxygen levels.



How often does the owlet monitor read heart rate and oxygen levels? Continuous? Every 2 min?


Hi Cindy! We definitely want to look into this for you. Give our team a call at (844) 334-5330 and they’ll help you out!



Hi-how long does it take for the owlet to react? It was green on my sons foot the entire tire while his heart rate fell to 50 and o2 fell to 30% without the alarm going off at all.


Great question, Cindy. The Owlet uses different algorithms to notify you if the sock fell off, it became disconnected to the base station, or if heart rate or oxygen levels left the preset zones. If you were holding the sock or put it on a soft surface, the sensor would sense movement or even try to get a reading from your skin, delaying the yellow notification further. This is not the same algorithm used to notify you if heart rate or oxygen left the preset thresholds. If you believe that your Owlet is not working properly, our team would love to look into this. Please give them a call at (844) 334-5330.



We’ve tried the owlet at the NICU to test it out and so far a couple of really desats and Brady’s did not warm off either the owlet. We even took off the owlet and almost two full minutes passed until alarm went off. Is this a faulty owlet we should exchange? How long after heart rate or oxidation level should an alarm go off?


Hi Ashley, this isn’t a feature that the Owlet offers.



I purchased the owlet for my unborn baby, still waiting on it to come. If my baby gets upset and cries obviously that will increase heart rate…is there a speaker of some sort so I can hear the baby if I’m in another room?



The owlet app will not display the charge amount while the sock is plugged in and charging. All it’s says in the menu option is that it is charging. It is a little frustrating to not have a sense how much the sock is charged besides it being fully done and no longer blinking green.


Nicole Roberts

Richelle, did you ever have any issues after your sock was submerged? Ours has been giving a few red notifications after it got submerged in the bath tub but I can’t tell if they are real notifications or false because oxygen levels are totally normal and it seems to work fine other than a sudden dip when it alarms and then everything seems fine after the red notificatio has been turned off and reset. I’m wondering how everything worked out with your situation or if you called owlet support?


Hey Sadie! Our team would love to take a look at this. They’re available at (844) 334-5330 Monday-Saturday 7am-9pm MT or through the chat feature in the Owlet App.



We charge our Owlet sock from the time our daughter wakes up around 6am to the time she goes to bed around 7pm yet we still get a low battery alert around 4am. If the charge should last up to 18 hours why does the alarm go off (and wake the baby) after only 9-11 hours? Is there anything we can do to prolong the battery life?


Hey! You may not be able to use it on the plane, as the Base Station will need a power source, but you can take it with you to your destination. We recommend fully charging the Sock Sensor and following the instructions to turn it off here: https://support.owletcare.com/hc/en-us/articles/203994909-Reset-Turn-Off-The-Smart-Sock



Can you travel on a plane with owlet? Do you have to turn the sock off somehow?


Pulse oximetry is very sensitive to movement so the movement of a swing can interfere with the Owlet’s ability to get a proper reading. In these instances, the Owlet will notify you with the ‘wiggle toes’ feature to help you know why it’s not able to share a live reading. The Owlet Smart Sock is designed to be used when the baby is sleeping in his or her own sleep space, like a crib or bassinet because of this.



Will an Alert be sent if baby is in a swing and moving? It says baby is moving and stops reading. My worry is, is that when we have him in a swing it won’t read and alert us as it should.


I’d give the Owlet Team a call at (844) 334-5330 Monday-Saturday 7am-9pm MT so they can look into this.



We have had the owlet for over nine months and it has worked great. However, we have had issues with the app saying our smart sock is low on batter after it was plugged in for several hours. What’s up?


Hi Richelle, you may want to give the Owlet team a call so they can ensure everything is still working properly. You can reach them at (844) 334-5330 Monday-Saturday 7am-9pm MT.



What if the owlet sock gets submerged under water for a short period of time? I see the red light still blinking but I’m unsure how much water may have gotten to it.


Hi Robert! Our tech support team would love to help you out with this. You can reach them through the chat option in the app or by email at contact@owletcare.com.



Just purchased and for two days i cannot get it to work, As soon as i turn on i get no reading. I am placing the sock as shown in diagrams but even being persistent i just cannot get it going. Any suggestions?


Hi Danielle! You can use your Owlet whenever you’d like, whether that’s nighttime sleep or daytime naps. Just make sure you leave 2-3 hours for it to charge.



Is it recommended to use the owlet for daytime naps as well as nighttime sleep?


Hi Christina! Just go into the app and it should be on the main menu part. You can also keep an eye on the dome on the sock while it’s plugged in. It will blink green while it’s charging and be a solid green color when it’s completely charged.:)



I do not see the battery life on the app when the sock is plugged in. How can I see this?


Hi Shawna! Sock fit and placement, as well as movement, can interfere with the Owlet’s ability to get a good reading. We recommend taking a look at our sock fit guide to make sure everything is in the right place. You can find that here: https://support.owletcare.com/hc/en-us/articles/115000882203-New-Sock-Sizing-Guide We’d like to look into why only one reading is showing up for you. Can you send our team an email at contact@owletcare.com with which mobile device, model, and operating system you use, along with the problems you’re experiencing?



Sometimes on the readings it will only show my LO HR and not the Oxygen level or visa versa. I was wondering why this is? I am also wondering my LO has the right sock on but sometimes the monitor moves up and it gives me low Oxgen readings like 92% instead of 100%. I am wondering if my LO movements can cause the monitor to get misplaced on my LO foot?

Kyrie Read

Hi! The Owlet Smart Sock 2 takes between 2-3 hours to fully charge.

Kyrie Read

Our team would love to look into this for you! Can you give them a call at (844) 334-5330 Monday-Saturday 7am-9pm MT?

Kyrie Read

Great question, Chris! The preset thresholds for heart rate are 60-220 bpm and oxygen is 80-100%.



What are the heart rate peramiters for low and high that would cause the alarms to go off?



Our newborn continuously gets bad connection alerts(always at 1-5am) never happens during the day so idk that it’s a placement issue but it creates poor sleep issues for mom


Robert Whitsett

How long does it take the smart sock 2 to fully charge?



Hi Brooklyn! We’re sorry about that! If you give us a call at (844) 334-5330 Monday-Saturday 7am-9pm MT, we’ll help you get that ordered!


Brooklyn boggs

I need to purchase 1 sock only for my 9’month old and I can’t seem we’re to find we’re I can buy 1 replacement sock



Hi Mikaela! We’d love to see what we can do to help you out! Can you please give us a call at (844) 334-5330 Monday-Saturday 7am-9pm MST?



I just ordered the owlet standard shipping but my baby has respiratory problems and we just left the hospital so I don’t have the monitors on her all the time anymore and it’s causing me to not sleep. Is there any way to change my shipping type to next day?



Hi Bethany! The Owlet is designed for babies 0-12 months old and fits most up to 18 months.



How long can u use the owelet on your child till they have grown out of it?



Hi Lacey! Yes, it can! You would just need to go through the setup process again.



Can the owlet be used for a second child? For example: passed down from an older sibling or cousin?



Hi Emily! Thanks for your suggestion! We’ll be sure to pass that along to our team!



It would be great if the app kept a log of previous alarms! Maybe just the past 3 to compare or something. That way if you don’t see what is alarming (because your waking baby) you could go back and check levels and times.


Hi Angela! The charging time will depend on the amount of time you have used the Smart Sock. However, if the battery is low, the sock will typically need to charge for around 4 hours. If you’re charging in between naps, this time will vary and we recommend keeping an eye on the dome on the sock. It will blink green while it’s charging and be a solid green color when it’s completely charged.



Please actually answer the question as to how long the sock takes to charge. Your answer above is a non-answer and not helpful in the least.



Hi Natalie! Thank you so much for the suggestion. We’ll be sure to pass that along to our engineering team!



Highly recommend a message or reading history feature. The alerts disappear and there is no way to review what they said.



Hi Kellie! We would love to talk to you about this. Can you call us at (866) 348-1767 Mon-Sat 7am-9pm MT? This way we can check your device to make sure everything is working properly. We definitely want you and baby to get more sleep!



Is it normal to have abnormally high heart rate alarms? Mine has gone off 3 nights in a row due to that. When I jump out of bed & startle my baby to see if she’s ok , it then causes her to cry & not go back into a deep sleep again at nigh. She’s perfectly fine & nothing seems wrong so why does it keep alarming ?


Lathrop Family

This would be a great feature. Our premie’s alarm went off for a high heart rate, however I was unable to look and see what the heart rate was because my first reaction was to check the baby- therefore the monitor was back to normal before I could check it.

Amber Nielsen

Having a low battery should not cause the Owlet to have more alerts than usual. However, a full charge will generally only last you one night, so we recommend charging your Owlet every day.



Does having a low battery or not charging it cause it to have more alerts than usual?


Hi Erin! We’re not a medical device however you can reach doctors through First Opinion here: https://firstopinionapp.com/ or in the ios app. We hope that helps!



I have been all over the FAQ looking for what to do when you have repeated red alerts. The low oxygen alert keeps going off and I don’t know if I should be concerned enough to take my daughter to the hospital since it is the middle of the night. She is still breathing but I’m scared to go to sleep when her readings are low and the alarm keeps going off. It would be nice if there was a next step of what to do.

Avatar for Brittany


Hi Jessica, thank you for your suggestion! We will make sure the engineers are aware of this request!



When a red alert goes off am I supposed to get a reason as to why? If not this should be a feature added. We had a red alert and instead of checking first I woke my daughter.
