Why Is Sonoff Motion Sensor Missing Nighttime Motion Events?
- low battery reduces PIR sensitivity
- mount angle/height mismatch
- temperature differential reduces detection quality
Problem Description
When your SONOFF Sonoff Night Motion Gaps isn't working as expected, it usually traces back to one of a small number of causes — this guide covers them in order, starting with the most likely.
Symptoms
- No night alerts
- delayed night detection
- short motion missed
Recognize these? Here's what usually causes it.
Common Causes
- low battery reduces PIR sensitivity
- mount angle/height mismatch
- temperature differential reduces detection quality
Most fixes happen in the first 3 steps.
Do not tune automations before confirming stable raw motion detection.

Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
PIR coverage should be validated under real nighttime temperature conditions.
Missed motion events are almost always a zone coverage problem, not hardware failure — zone placement accounts for 90% of these complaints.
- low battery reduces PIR sensitivity
- mount angle/height mismatch
- temperature differential reduces detection quality
