Motion Sensor Not Triggering Lights
4.5
You walk into a room but the smart lights stay off.
Symptoms
- No trigger
- Delayed response
- False triggers
Possible Causes
- Dead battery
- Out of range
- Automation rule error
Step-by-Step Fix
1
Replace Battery
Most sensors use CR2032 or CR123A batteries that last 1-2 years.
2
Check Automation Rule
Ensure the "If Motion Detected" rule is still active and has the correct time range.
3
Adjust Sensitivity
Increase sensitivity in the app if it's missing smaller movements.
When to See a Technician
PIR sensors can struggle in very hot rooms as they look for temperature changes.
