Does this apply to my device?

For a battery-powered motion sensor on your E2 Technologies system with a Device Low Battery alert in the Alarm.com app. This is a guide to finding instructions, not a universal battery replacement procedure. It does not apply to panel backup batteries or wired sensors.

Before you begin

You need the Alarm.com app and a login allowed to view system issues. Battery type, panel precautions, and replacement steps depend on the installed model.

Steps

Sign in to the Alarm.com app.
In Issues, select the Device Low Battery alert for the affected motion sensor.
Select Fix It to look for device-specific guidance.
Before any replacement, confirm that the instructions match your model and include the required battery and panel precautions. If guidance is missing or the match is uncertain, stop and contact support.

Expected result

You should have matching device instructions or enough information to request help. Finding the guide alone does not clear the alert; follow only confirmed instructions and their checks for successful replacement.

If you still need help

If no matching guide is available or the alert persists after following verified instructions, contact support with the sensor name, model if known, and steps attempted. Do not trigger an alarm to test the sensor.
