What the sensor does and who it fits

The Emerson MS600 is a wall-mounted smart sensor that combines PIR, millimetre-wave radar and a light detector in one unit. It reports human presence even when no movement occurs and integrates with HomeKit, Alexa, Google Home and Home Assistant. Builders who need a battery-powered device or who do not have a permanent power outlet at the mounting location cannot use this sensor.

The spec that decides compatibility

A Matter hub is required for Matter-level control, although HomeKit, Alexa, Google Home and Home Assistant work without one. The sensor connects only to a 2.4 GHz Wi-Fi network during setup and operation. Buyers whose home network lacks a 2.4 GHz band or who do not own a Matter hub will not gain Matter functionality.

Heat, noise and power in daily use

The unit draws continuous power from the included 1.5 metre corded supply and contains no fan or moving parts, so it runs silently. Its lightweight 0.181 kilogram chassis produces negligible warmth during normal operation.

Questions about this item

How far does the 12-meter motion detection actually reach in a typical room?

The sensor detects motion up to 12 meters and registers human presence up to 6 meters, so it covers most living rooms and hallways from a single mounting point.

What does the 2.4 GHz Wi-Fi requirement mean for my network setup?

The device only connects to 2.4 GHz networks; you must select that band during setup, but once paired it works with Matter, HomeKit, Alexa, Google Home and Home Assistant without a separate hub for those platforms.

Will the 180° pivot and 360° rotation base fit on my wall or ceiling?

The adjustable base pivots 180° and rotates 360°, includes cable management for the 1.5 m power cord, and mounts on walls or ceilings so you can aim the detection zone precisely.
