Product detailed description

🏃 Compact Zigbee and Bluetooth Motion and Light Sensor

Thanks to its built-in PIR motion sensor and LUX light sensor, Shelly BLU Motion ZB detects human movement and ambient light levels in real time. This makes it ideal for lighting control, security alerts, energy-efficient automation, and motion-based smart home scenarios. 

BLU Motion ZB supports dual wireless protocols, enabling simultaneous operation on Zigbee 3.0 networks and via Bluetooth 5 LE connectivity. Thanks to integrated BTHome support, it seamlessly connects with Shelly devices, Home Assistant systems, and other compatible platforms. Adjustable motion sensitivity and configurable brightness levels allow precise adaptation of the sensor to the conditions in any room.

Wireless operation and the included double-sided adhesive tape ensure fast and easy installation without the need for wiring or wall modifications. The included CR2477 battery can provide up to five years of operation, enabling long-term maintenance-free use. It is a great choice for hallways, entrance halls, bedrooms, living rooms, garages, and offices where lighting and automation should respond to actual human presence and environmental light conditions.

The sensor can be used for automations such as automatic hallway night lighting, bedside light control, entrance monitoring, or motion detection around garages and gardens. In combination with scenes in the Shelly Smart Control app, motion detection can trigger lights, relays, blinds, and other Shelly devices.
