Detects people, even when they are sitting still. The Shelly Presence Gen4 is a 60 GHz mmWave radar presence sensor that tracks up to 10 people in up to 10 customizable zones, covering up to 450 sq ft. With Wi-Fi, Zigbee, Bluetooth and Matter and a built-in light sensor, it automates lights and climate based on real presence, not just motion.
WHY SHELLY PRESENCE GEN4?
Room-aware automation that feels natural
Unlike PIR sensors, the radar detects breathing-level micro-movements, so lights stay on while you read, work or watch TV. Adjustable sensitivity lets it ignore pets, kids or robot vacuums, and the light sensor reports dark, twilight and bright levels.
Powered by USB-C, the Shelly Presence Gen4 sits on its weighted stand on a shelf, table or wardrobe, or mounts on a wall with screws or adhesive. It works with the Shelly Smart Control app, Home Assistant and any Matter ecosystem.
