Shelly BLU Door and Window Bluetooth Sensor White

Shelly BLU Door and Window Bluetooth Sensor White The Shelly BLU Door/Window Sensor is a compact Bluetooth smart sensor designed to detect the opening and closing of doors and windows while also monitoring tilt angle and ambient light levels. Its discreet white finish, fast response and long battery life make it ideal for security, lighting automation, access monitoring and energy-saving smart-home applications. Key Features: Bluetooth door and window sensor White finish Detects opening and closing events Integrated tilt angle sensor Integrated ambient light sensor Supports tilt-and-turn windows Bluetooth 4.2 connectivity BTHome protocol support Beacon mode AES encrypted communication Up to 5 years battery life CR2032 battery included Compact 35 x 35 x 7mm sensor body Up to 10m indoor Bluetooth range Integrates with Shelly scenes and automations Features Fast Door and Window Detection The Shelly BLU Door/Window Sensor detects changes in door or window position and broadcasts the open or closed state to compatible Shelly devices and gateways, allowing automations to react quickly to access events. Tilt Angle Monitoring An integrated G-sensor measures the inclination angle of compatible tilt-and-turn windows, allowing automations to distinguish between fully closed, opened and tilted ventilation positions. Ambient Light Measurement The built-in light sensor measures surrounding illumination levels, allowing lighting and energy-saving automations to respond to both occupancy events and ambient brightness. Up to 5 Years Battery Life The sensor operates from a single replaceable CR2032 battery and provides up to approximately five years of battery life under normal use, reducing maintenance requirements. Compact Low-Profile Design The main sensor measures only 35 x 35 x 7mm and the magnet measures 35 x 12 x 7mm, allowing discreet installation on windows, doors, cupboards and other access points. Shelly Smart Automation The sensor can be used in Shelly scenes and automation routines, such as turning off heating when a window opens, activating lights when a door is opened or triggering security notifications. A compatible Bluetooth gateway is required for remote Shelly Smart Control access. Compatible gateways include supported Shelly Plus, Pro, Gen3 and Gen4 devices or a Shelly BLU Gateway. Beacon Mode can reduce battery life because the device broadcasts more frequently.
