Description
mmWave presence sensor with Matter, WiFi, Zigbee and Bluetooth
The Shelly Presence Gen4 is a compact presence sensor that uses mmWave radar to detect people even when they are sitting or standing still. It is suitable for more precise automations for lighting, climate control and energy saving in a Smart Home.
Unlike a traditional motion sensor, the Presence Gen4 was designed to detect real presence in the space. It can track up to 6 people simultaneously, configure up to 10 detection zones and cover an area of up to 42 m², depending on the installation and site conditions.
Main features
✔ Presence detection by mmWave radar, even without visible movement
✔ Tracking of up to 6 people simultaneously
✔ Up to 10 configurable zones for area-based automations
✔ Integrated light sensor with dark, twilight and bright states
✔ Adjustable sensitivity to reduce false triggers from pets, children or robot vacuums
✔ Multi-protocol connectivity: WiFi 6, Zigbee 3.0, Bluetooth 5 LE and Matter-over-WiFi
✔ Flexible installation on wall, table, shelf or cabinet
Usage example
Install the sensor in a living room or office to turn the light on only when there is real presence and switch it off automatically when the space becomes empty. In larger rooms, the zones allow lighting or climate control to be activated only in the occupied area.
