Window sensor

I have installed multiple new batteries in my window sensor, but the app still says the battery is low.

Good morning, @matthew2942 ! I’m sorry your window sensor is still showing a low battery after replacing it multiple times. Sometimes the sensor may not immediately register the new battery. Please remove the battery, wait about 5 minutes, then reinstall it, making sure it’s positioned correctly and the sensor cover is completely secured. Afterward, check the Xfinity app again to see if the low-battery alert clears. If it’s still showing low after that, please let us know so we can take a closer look.
