meross Matter Presence Sensor MS605, Battery-Powered 4-in-1 Smart Motion Sensor with AI Learning, IP67 PIR & Light & mmWave Radar, Matter Over Thread, Supports Home Assistant, HomeKit, Alexa (1 Pack)

The meross MS605 is a fully wireless 4-in-1 presence sensor that pairs PIR, ambient light, and mmWave radar with on-device AI learning to deliver reliable occupancy detection without the false triggers of a basic motion sensor. It runs on Matter over Thread for low-latency, local-network automations and works with Apple Home, Amazon Alexa, Google Home, SmartThings, and Home Assistant through any Matter controller with a Thread border router. The IP67 rating makes it suitable for entryways, garages, and other harsher spots where most indoor sensors can’t go, and battery operation means no wiring required.
