A presence sensor that sees stillness
Shelly Presence Gen4 detects the presence of people with a 60 GHz mmWave radar even when they sit or sleep without moving, and tracks up to 6 people in 10 zones at the same time.
The mmWave radar, which operates on millimeter waves, registers tiny body movements that a standard PIR sensor does not see. On a wall it covers an angle of 140° and an area of up to 8 x 8 m, and the built-in light sensor distinguishes three levels of ambient brightness.
It connects via WiFi 6, Bluetooth, ZigBee 3.0 and Matter over WiFi, so you can add it to Google Home, Amazon Alexa, SmartThings and Home Assistant. This version has a white housing with an aluminum back, while the black version has identical parameters and dimensions.

Consider another option if:
- A battery-powered motion sensor is enough for you: choose Shelly BLU Motion ZB

The recommended mounting height is 2 meters
The manufacturer recommends mounting the Shelly Presence Gen4 sensor at a height of about 2 m, tilted about 15° downward. The sensor works in rooms up to 5 m high, and in the app you can rotate the image by 180° if you mount it upside down. The nominal power consumption of the sensor is 2.5 W, and the maximum is 3.5 W when powered with 5 V DC.
