Shelly BLU Motion ZB – Wireless motion sensor with light sensor, Bluetooth, Zigbee, white (SBMO-103Z)

The Shelly BLU Motion ZB is a compact, battery-powered motion and light sensor featuring both Zigbee and Bluetooth connectivity. Equipped with a built-in PIR motion sensor and LUX light sensor, it detects human movement and ambient light levels in real time, making it ideal for lighting control, security notifications, energy-efficient automation, and motion-based smart home scenarios.

The BLU Motion ZB supports dual wireless protocols, allowing simultaneous operation on Zigbee 3.0 networks and Bluetooth 5 LE connections. Thanks to built-in BTHome support, it integrates easily with Shelly devices, Home Assistant systems, and other compatible platforms. Adjustable motion sensitivity and configurable brightness levels allow the sensor to be precisely adapted to the conditions of each room.

Wireless operation and the included double-sided adhesive tape make installation quick and simple, with no wiring or wall modifications required. The included CR2477 battery can provide up to five years of operation, enabling long-term maintenance-free use. It is an excellent choice for hallways, entryways, bedrooms, living rooms, garages, and offices where lighting and automations should respond to actual presence and ambient light conditions.

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