ANSWERED: What to do when you receive the low battery warning on your Xfinity Home Security device.

Your installed XFINITY Home devices come pre-installed with batteries, and over time, those batteries will begin to expire. When this happens, you will receive notifications through your Touchscreen, XFINITY Home subscriber portal, and your XFINITY Home Mobile app.

It is important to replace your battery within two weeks of receiving the notification. The system will continue to function properly, but if the battery dies completely, the associated device will lose all functionality:


  • Any rules associated with the device will not trigger
  • If the device is a door/window or motion sensor, it will not sound alarm if it is tripped while the system is in “Arm” state. In order to arm the system while a device is in complete failure, users must bypass the zone.


What You'll Need

  • XFINITY Home
  • Access to your XFINITY Home devices
  • Access to the XFINITY Home app for mobile devices, Subscriber Portal or Touchscreen Controller
  • Small flathead screwdriver
  • Small Phillips-head screwdriver
  • Replacement batteries (see devices below for battery types and number of batteries required)
  • Two-sided tape (for certain Wireless Keypads and Sensors)
