Description
The Shelly BLU Motion ZB is a compact, battery-powered motion and ambient light sensor designed for flexible residential and commercial smart home installations. With simultaneous Zigbee 3.0 and Bluetooth connectivity, it can integrate with compatible Zigbee hubs, Shelly gateways and supported automation platforms.
Its PIR sensor provides reliable motion detection with adjustable sensitivity, allowing installers to tailor its responsiveness to suit hallways, entryways, living areas, offices and other monitored spaces. The built-in LUX sensor measures surrounding light levels and supports configurable dark, twilight and bright thresholds, enabling automations to operate according to both movement and actual room brightness.
Use the Shelly BLU Motion ZB to activate lighting when movement is detected, send security notifications, control connected devices or trigger customised scenes. Beacon mode can also provide regular status updates for compatible systems and more advanced automation applications.
Powered by an included CR2477 battery with a battery life of up to five years, the sensor requires no electrical wiring and offers a low-maintenance solution for new installations and retrofits. Its compact design and included adhesive mounting make it easy to position on a wall or ceiling wherever motion monitoring is required.
The Shelly BLU Motion ZB supports BTHome and secure AES-encrypted communication. A compatible Bluetooth gateway, Zigbee hub or supported smart home platform is required for app control and automation functionality.
