Aqara Motion and Light Sensor P2

Quick verdict

A clean, no-nonsense motion sensor that runs on Thread and needs no Aqara hub, though it does need a Thread border router on your network. Pair it with Home Assistant via Matter and you get motion plus light level readings, all fully local. It will not detect someone sitting still like mmWave sensors do, and Aqara documents a 1-minute gap between motion reports, but for triggering lights when you walk into a room it is reliable and hassle-free.

Standout: Thread-native motion and light sensor that needs no Aqara hub, just a Thread border router, with full local control.

Compatibility snapshot

Why it stands out

• Thread-native motion sensor that needs no hub, just a Thread border router
• includes a light level sensor alongside motion detection for smarter automations
• fully local via Matter with zero cloud dependency

Reasons to hesitate

• PIR motion only, no mmWave presence detection like the FP series
• requires a Thread border router on your network
• Aqara documents a 1-minute motion detection interval, so it will not report motion again within a minute of the last trigger (the illuminance reading updates every 30 seconds)

Best for

• Thread-based Home Assistant setups that want simple, reliable motion triggers
• hallway and room lighting automations that also factor in ambient light levels

Avoid if

• you need true presence detection. PIR only catches movement, not still occupancy
• you do not have a Thread border router and do not want to set one up

Privacy and local-control notes

Fully local via Matter over Thread. No cloud account needed for operation. No camera or audio, just PIR motion and light level.

Home Assistant support: supported · integration path: matter.

Buying reality check

Price notes: Mid-range pricing is fair for a Thread-native sensor with dual motion and light level reporting.
