A USB-C powered 60-64 GHz mmWave radar presence sensor that detects stationary occupants across up to 10 zones, with a built-in illuminance sensor for lighting-aware automations. Multiprotocol Wi-Fi, Bluetooth, Zigbee, and Matter for flexible integration.
Works on integrations
Protocols
One mode at a time: the device serves one of these combinations, not all of them at once.
Setup guides
Roles it can fill
Native Shelly integration, local, no cloud required (also MQTT, scripting, and webhooks). Mains-powered via USB-C with mmWave radar presence detection, multi-person and multi-zone tracking, and a built-in light sensor; multiprotocol over Wi-Fi 6, Bluetooth LE, Zigbee 3.0, and Matter-over-Wi-Fi.
