App Alarms

The BabySat App will only mirror Base Station alarms when the mobile device is unlocked, the app is open and connected to the same Wi-Fi network as the Base Station (Direct Connection).

Warning: Always keep the Base Station in audible range. Use the Base Station as your source for alarms and check on the baby first. DO NOT rely on mobile devices for alarms.

What Should I do?

Immediately check on the baby. Use your experience as a caregiver to determine if there is a change in the infant’s status that may require intervention and follow any directions provided by your Healthcare Provider.

If your child is ill, including fevers or congestion, you may see more frequent red alarms. Contact your medical provider if you have concerns.

If your baby appears to be in their usual state of health, the red alarm may have been caused by one of the following:



Sometimes when there is movement, it can cause an invalid reading or a false alarm. Stop or pause monitoring during prolonged periods of movement.

Sock Placement

Sometimes the Sock can be close enough to get a reading, but still too loose, causing faint readings.


When your child is feeding, movement can cause an invalid readings.


Kicking while crying may cause an invalid reading due to movement. 

Elevation or cold feet

High elevation or cold feet can make red alarms more frequent.
