Shelly BLU Door/Window ZB Zigbee Bluetooth Smart Door Window Sensor White

The Shelly BLU Door/Window ZB is a compact, battery-powered smart sensor that detects when doors, windows, cabinets, or drawers are opened or closed. Supporting both Zigbee 3.0 and Bluetooth, it integrates seamlessly with leading smart home platforms and provides instant alerts and automation triggers in your smart home ecosystem.

Advantages

Beyond simple open/close detection, the BLU Door/Window ZB also monitors tilt, vibration, ambient light level, and temperature — making it a versatile multi-purpose sensor in a tiny form factor. A single CR2032 battery powers the device for up to 5 years, making it virtually maintenance-free. With dual-protocol support (Zigbee 3.0 and Bluetooth 4.2 BLE), it works natively with Home Assistant, SmartThings, Hubitat, and the Shelly Smart Control app, offering broad compatibility without lock-in.
