Recently bought 4x “Human Motion Sensor” from AliExpress. They’re the ZigBee models, cheap (£3.87 UK BGP each) and wanted to do some investigation:
They’re listed as “ZigBee Human Motion Sensor Radar Mmwave Temperature and Humidity Sensor Security Burglar Works With Home Assistant Zigbee2MQTT“, and I went for the 2-in-1 model (presence and luminescence), rather than the 3-in-1 model (also includes temp / humidity).
They arrived quickly, and the packaging describes them as from:
