The 60–64 GHz radar detects a person even without movement, so automations such as lights, HVAC and scenes remain active as long as someone is in the room. It is ideal where PIR sensors fail—when working at a desk, reading or watching TV.
The sensor can track up to 6 people and set up to 10 detection zones. In larger rooms, you can trigger actions only in specific parts of the space and reduce unnecessary lighting or energy consumption.
Shelly Presence Gen4 integrates easily into a smart home thanks to Wi‑Fi 6, Zigbee 3.0 and Bluetooth 5 LE. It also supports Matter over Wi‑Fi and offers a built-in web interface for convenient setup without the need for additional apps.
Shelly Presence Gen4 (Black) takes home automation further than standard PIR sensors. The 60–64 GHz radar detects true presence, so lights, air conditioning or smart scenes do not switch off when you are simply sitting still. The result is greater comfort and less unnecessary device switching.
Use advanced scenarios based on exactly where someone is located in the room. The sensor can simultaneously track up to 6 people and lets you set 10 independent zones that can be used as separate triggers in automations, including integrations via Matter. To minimise false alarms, it offers sensitivity, power and floor-level motion-filtering settings—useful, for example, in homes with pets.
Integration is quick thanks to Wi‑Fi 6, Zigbee 3.0 and Bluetooth 5 LE. The device works with Shelly Cloud and Home Assistant and also supports Amazon Alexa, Google Smart Home and Samsung SmartThings. Another major advantage is the light sensor with dark, dim and bright readings for more natural lighting scenes. Since mmWave works without a camera, it helps protect privacy even in bedrooms, bathrooms or offices.
