Description
The Shelly BLU Door/Window ZB is a compact wireless sensor designed for reliable door and window monitoring in residential and commercial smart home installations. Supporting both Zigbee and Bluetooth connectivity, it offers flexible integration with compatible gateways, hubs and automation platforms.
The sensor detects when a door or window is opened or closed and can be used to trigger customised alerts, security routines, lighting, heating, cooling and other automated actions. Built-in tilt detection also allows compatible systems to identify the position of a window, while the integrated light sensor can provide ambient light data for more advanced automation conditions.
Its compact, wire-free design allows for quick installation without the need for additional cabling, making it suitable for new installations, retrofits and security upgrades. The low-power operation and replaceable battery help reduce ongoing maintenance requirements across larger installations.
Ideal for monitoring entry doors, windows, cupboards, garages and other access points, the Shelly BLU Door/Window ZB provides installers with a versatile and discreet sensor for expanding compatible Zigbee and Shelly smart home systems. A compatible Zigbee coordinator, Bluetooth gateway or supported smart home platform may be required, depending on the selected connection method.
