Tuya mmWave Human Presence Sensor Zigbee/WiFi
Tuya · Human Presence Sensor
Smart human presence sensor based on mmWave radar, designed to detect motion and static presence in indoor spaces. It is available in Zigbee and WiFi versions, and can measure presence, movement, distance, and ambient light. The Zigbee version can be integrated into Home Assistant via Zigbee2MQTT, while the WiFi version is geared toward use with Tuya Smart or Smart Life.
