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 lighting, climate control, and energy-saving automations in a Smart Home.
Unlike a traditional motion sensor, the Presence Gen4 was designed to perceive real presence in the space. It allows tracking up to 6 people simultaneously, configuring up to 10 detection zones, and covering an area of up to 42 m², depending on the installation and local 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 animals, children, or robot vacuum cleaners
✔ 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 on the light only when there is real presence and turn it off automatically when the space becomes empty. In larger rooms, the zones allow triggering lighting or climate control only in the occupied area.
