Discover a smarter way to monitor doors and windows
Shelly BLU Door/Window Mini ZB
Compact and designed for tighter installations, this compact battery-powered
sensor is built for doors and windows where space is limited. It detects open/close
status, tilt angle, and ambient light, giving you more context than basic contact
sensing and helping you create smarter automations in compact spaces.
With Bluetooth and Zigbee connectivity, it integrates easily into the Shelly
ecosystem and supports fast, reliable status updates with low power consumption.
From narrow window frames and tilt-and-turn windows to closets, pantry doors,
and other tight indoor spaces, it adds flexible monitoring where standard sensors
may be too bulky.
Ideal for slim window frames and tight reveals where larger contact sensors are difficult to mount. Compact housing allows reliable open/close monitoring on smaller bathroom, bedroom, or secondary windows, helping detect unexpected openings without compromising installation flexibility.
Tilt Ventilation Control
Uses inclination angle measurement to distinguish a tilted window from a fully open one. This allows automation to trigger dedicated ventilation routines, reduce unnecessary alarms, and support smarter heating or cooling routines in apartments, hotels, and other multi-unit buildings.
Ambient Light Automations
Use illumination sensing to turn on lights when a closet or pantry is opened in low light, helping prevent forgotten lights and improving convenience.
