FAQ

Q: Why does my baby have red marks on their feet after wearing Smart Sock S320? A: A baby's skin is very sensitive and delicate. Prolonged use of smart socks in high temperatures or humid environments may lead to red marks or imprints. Additionally, if a baby frequently kicks, the continuous friction could cause localized abrasions or even blisters. If this occurs, please check the following: -- Ensure you have chosen the correct sock size. -- Make sure your baby's feet, and Smart Sock S320, are clean and dry. -- Ensure there are no open wounds on your baby's feet. For more details, check the blog in the app.

Q: Is eufy Baby Smart Sock safe for my baby? A: Yes, eufy Baby Smart Sock is safe for daily use with your baby when used as instructed. The sensor tracks your baby's sleep via light reflections (PPG technology) and baby's movements. The sock uses high-quality fabric that wraps comfortably on your baby's feet. All components of the smart sock are carefully selected and manufactured with quality in mind. We have collaborated with parents like you and engaged in rigorous tests to make sure the sock is safe for all.

Q: Does the device generate any radio emmisions that would harm my baby? A: Smart Sock is not harmful to the baby as it has been tested and meets the applicable limits for radio frequency (RF) exposure. The sock connects with the base periodically via Bluetooth Low Energy 5.0 (2.4GHz) that has low power output. The base and camera connect to your phone via Wi-Fi like any other Wi-Fi-connected devices in your room.

Q: Will Smart Sock cause a choking hazard to my baby? A: Smart Sock is safe for your baby and meets the safety standards. As a precaution, keep the sock sensor away from your baby's mouth.

Q: Why doesn't the product send alerts or notifications? A: The sock alerts you for low battery, Bluetooth disconnection, and improper wearing. To receive these notifications, make sure to choose the correct sock size and that it's worn properly.

Q: How does Smart Sock track my baby's sleep? A: Our sleep algorithm detects the baby's current sleep state based on movements and heart rate. You can use the sock to track daytime naps and nighttime sleep. External activities will affect sleep detection, such as sleeping in a moving stroller, in a car, in a moving bassinet, or being carried in your arms. The sleep detection algorithm best suits a baby sleeping in a bed/crib.

This sock is a significant improvement over the Owlet! Every issue the Owlet had has been addressed and enhanced with this design, making it a far superior option.The most significant difference is the ability to customize alerts, allowing you to adjust how they are received, at what volume, and how frequently. Another key improvement is that this product can be used in separate rooms from the base, providing greater flexibility.However, the most notable improvement is the placement of the monitoring probe. This design ensures the sock remains securely in place, making it far more reliable. This addresses a major issue with the Owlet, which often had problems with the sensor shifting out of position.The monitor is great give me the information and peace of mind I needed! Additionally it is easy to apply on my baby and it seems to be comfortable for him to use.Overall, while this product is expensive and not necessarily essential for everyone, it offers long-term value by providing support through various stages of a baby’s development—particularly during times of uncertainty and anxiety. It is a reliable solution that brings peace of mind when parents need to rest and cannot constantly monitor their baby.

I couldn’t be happier with this smart sock. Our daughters have had convulsive seizures, so we have multiple monitors to give us peace of mind at night. The Eufy Smart Sock is a great value and has all the features I need. I love that I can set the parameters for notifications and that I can allow it to notify me (audibly) even when my phone is on Do Not Disturb at night.I want to highlight one experience. My baby was napping, and I was watching her on a monitor. I saw her start having a seizure, so I rushed in and took care of her. The Eufy notified me that her heart rate was abnormal after she had been seizing for 15 minutes. This may sound like a long time, but if it were the middle of the night, being notified 15 minutes in would be better than not being notified at all. Now I know it will notify me, which brings me greater peace of mind. I set the heart rate range a little lower so I will be notified sooner in the future.I know these are not medical devices and I can’t depend on baby monitors to keep my kids safe, but if it can calm my anxiety the tiniest bit, it’s worth the money.

Not sure why some people are saying it doesn’t ready blood ox but it does. The sock seems to be a better design with the device sitting on top of the foot, more comfortable for baby. I like that you charge the sock on the base and there is no need for extra chargers or wires.

High stars for peace of mind, especially if you're a first time parent. Material around the sensor is impossible to clean, but you can buy new socks/straps when they get funky, because for some reason they just don't get as clean as you'd like them to be.

Not the best heart rate tracker for babies. The sock is not very accurate and the O2 doesn’t notify you if it drops below a certain number.

This device is awful. I should have read the reviews before purchasing and I normally do but I didn’t on this and I learned my lesson. It doesn’t alert you with the babies blood oxygen nor does it read the blood oxygen right in my opinion. I purchased this for peace of mind and it gives me none. My baby never has 100 % o2 the whole time we have used it. Tonight as I’m looking at the sock his o2 started going down 1 point at a time all the way to 81 and he was awake and fine so needless to say I was having a heartache even though he was fine. DO NOT BUY THIS! I have ordered the owlet and it will be here soon and let’s just say spending the extra is worth it for peace of mind and you get what you pay for. Take these off the market!!! If I could give zero stars I would! Stick to other electronics eufy!

This was very easy to set up. The app is user friendly which is nice. The sock goes on easily and I like seeing real time heart rate and oxygen and her activity level. But, I have a few issues with it. First, the sock fell off one night and NEVER alerted me. It was still showing heart rate and oxygen levels- how? The sock was not even on my daughters foot. Second, oxygen levels are not always accurate- one night, reading in the low 80s although another pulse oxygen monitor I have read 99%. It also will NOT alert you for low oxygen which is quite disappointing when other comparable devices do. Third, the sleep tracking is questionable at best. It does not accurately reflect my daughters awake times which is annoying. I just don’t think this device is accurate or reliable at all and will be returning and purchasing something else.

We’ve been using this product for about 10 months now. I would agree that it’s done its job. We have not had many false alert, alerts or readings as per some of the other reviews. They have happened and baby was checked and doing just fine. Definitely helps for the transition to sleeping in a crib or if baby is in another room. Helps to reduce anxiety. We only use this at night time sleeping, not used for naps. The product should also be washed, there are other reviews, saying it hurt babies foot, I would say that would only be of concern if the product gets sweaty and is not kept it clean. Overall, very satisfied with this, if you were on the fence, just buy it for a piece of mind. And resell it later when your done

A very nice product, I am compiling a video review and will leave the link here later. Easy to use, and has a speaker system that would alarm you about any issues happening without having to carry your phone around with you all the time.

Offers peace of mind, we can’t sleep without him having it on. Sleep tracking is a little wonky and we have had one false alarm so far
