Shelly Presence Gen4 - smart presence sensor

Shelly Presence Gen4

Shelly Presence Gen4 is a presence sensor that uses mmWave radar technology to detect people in a room even when they are not moving. Unlike conventional motion sensors, it can also detect stationary presence, enabling more accurate and natural automation scenarios.

The device supports tracking multiple people at the same time and zone-based detection with up to 10 zones, so you can automate lighting, heating or security exactly where people actually are. Adjustable sensitivity helps prevent false alarms (e.g. from pets or robot vacuums).

Multi-protocol support (Wi-Fi, Zigbee, Bluetooth and Matter) ensures easy integration with a wide range of smart home systems. Its compact design and flexible mounting options let you place the device on a wall, shelf or desk.
