A small radar presence sensor that detects people even when they are still, sitting or asleep, not just when they walk past. It reports four states: presence, static presence, micro-motion and full motion, and adds a light sensor for automations. Two radar versions exist: 5.8G for simple rooms and 24G for faster response and distance-zone sensitivity tuning. It runs on Tuya Smart or Smart Life over ZigBee or WiFi, so it fits most smart-home setups but needs a hub or network to be useful.

This is an mmWave human presence sensor that works with the Tuya Smart / Smart Life app. It detects human presence, static presence, micro-motion and full motion. That means it can pick up a person who is sitting still or sleeping, small movements like using a phone or turning a page, and larger movements like walking, running or jumping.
It comes with a 5.8G or 24G radar. The 5.8G version is set up simply and suits everyday home use. The 24G version responds faster, lets you tune sensitivity by distance zone, and suits more complex environments. A built-in light sensor reports ambient brightness so lights can be switched on or off by scene linkage.
The sensor attaches magnetically to iron surfaces such as table corners, frames and steel beams. It can also be mounted on a wall or ceiling with double-sided adhesive. The adjustable bracket sets the detection angle. A debug mode with live indicator-light feedback helps you find the best detection range and spot interference. A range report mode can be set to report only on trigger, which reduces network traffic. It works with ZigBee2MQTT and Home Assistant.
