Fits narrow frames where standard sensors cannot. The Shelly BLU Door/Window Mini ZB is a compact, battery-powered door and window sensor with tilt detection, an ambient light sensor and dual Zigbee 3.0 & Bluetooth 5 LE connectivity. Up to 5 years of battery life means low-maintenance monitoring.

WHY SHELLY BLU DOOR/WINDOW MINI ZB?

Small size, smarter automations

It detects opening and closing events and also measures the tilt angle - useful for spotting tilted tilt-and-turn windows or partial openings.

The built-in light sensor lets the Shelly BLU Door/Window Mini ZB react not only to door or window movement but also to ambient light, for example turning on a light when a door opens in a dark room. Use it with any Shelly Plus, Gen3, Gen4 or Pro device as a Bluetooth gateway, or with your Zigbee hub.

KEY FEATURES

  • Mini-frame compatibility: fits narrow frames and tight reveals
  • Dual connectivity: Bluetooth 5 LE and Zigbee 3.0
  • Light sensor: measures ambient illumination for light-based automations
  • Inclination angle measurement: detects tilt positions for tilt-and-turn doors and windows
  • Up to 5 years battery life: CR2032 battery included
  • Encrypted communication: AES encryption in CCM mode
  • Beacon mode: periodic broadcasts of status, ambient light and battery level

Note: Battery-powered, so it works with any mains voltage.
