Shelly BLU Door/Window ZB
Smart opening, tilt and light detection with Zigbee and Bluetooth connectivity.
The Shelly BLU Door/Window ZB is a compact wireless sensor designed to monitor whether a door or window is open or closed. It can also measure the angle of compatible tilt-and-turn windows and monitor ambient light levels, giving you more options for security, notifications and smart-home automations.
With both Zigbee 3.0 and Bluetooth 5 LE, the sensor can operate over Zigbee and Bluetooth simultaneously. It also supports BTHome for compatible Bluetooth integrations.
Key Features
- Zigbee 3.0 and Bluetooth 5 LE: Supports simultaneous Zigbee and Bluetooth operation.
- Open and closed detection: Monitor doors and windows and use changes in status to trigger automations.
- Tilt-angle measurement: Detect the angle of compatible tilt-and-turn doors and windows, including partially open ventilation positions.
- Ambient light measurement: Create automations based on the surrounding illumination level.
- BTHome support: Suitable for compatible Bluetooth-based smart-home integrations and automations.
- Long battery life: Designed to provide up to five years of operation under normal conditions.
- Encrypted communication: Encrypted mode helps protect communications from the sensor.
- Compact design: Its slim profile makes it suitable for discreet installation on doors and windows.
Smart Automation Ideas
- Receive an alert when a door or window is opened.
- Turn lights on when a door opens in low-light conditions.
- Pause heating or air conditioning when a window is left open.
- Monitor whether a tilt-and-turn window is closed, tilted or fully open.
- Use opening events as part of a home security automation.
Operating Modes
Regular Mode
When the door or window changes between open and closed, the sensor broadcasts its current status together with the illumination level and battery status. For compatible tilt-and-turn installations, it also checks and reports changes in the window’s tilt angle.
Beacon Mode
Beacon Mode broadcasts the open or closed status, illumination level and battery status approximately every 30 seconds. This mode can be enabled through the Shelly Smart Control settings.
Please note: Frequent broadcasts in Beacon Mode may significantly reduce battery life.
