The compact wireless Shelly BLU sensor reliably monitors door/window opening/closing, measures tilt angle, and tracks light level. Thanks to Bluetooth 4.2, AES encryption, and battery life up to 5 years, it’s an ideal choice for smart homes and small commercial spaces.
Make your home smarter and more secure. The Shelly BLU in brown discreetly blends with door or window frames while accurately detecting open/close, tilt, and, via its integrated light sensor, the current illumination. Communication over Bluetooth is fast and efficient, and all data is encrypted (AES-CCM).
Choose the mode that suits you: standard mode reports events when an opening is detected, while beacon mode broadcasts status information every 30 seconds for continuous monitoring. Powered by a single CR2032 battery, the sensor achieves up to 5 years of life and installs easily without cables.
