## Long description

The Shelly BLU Door Window Sensor is a compact wireless Bluetooth sensor designed to monitor the open/closed status of doors and windows. With a minimalist footprint of 3.5 cm by 3.5 cm and low-power design, the sensor runs on a single CR2032 alkaline battery and delivers long operational life, reducing maintenance frequency. The device communicates status changes via Bluetooth to compatible Shelly BLU gateways and apps, enabling simple pairing and remote state monitoring within Bluetooth range.
Advantages
The device provides discreet monitoring with a small form factor that fits on narrow frames and profiles. Long battery life of up to 60 months under typical use lowers the need for frequent replacements. Bluetooth connectivity allows quick setup without wiring, while compatibility with Shelly BLU ecosystems offers integration into existing smart home routines. The sensor’s sealed enclosure supports reliable operation in interior door and window installations.
Suitable for
Residential doors and windows where discreet status monitoring is required
Rental properties and apartments for low-maintenance security monitoring
Smart home setups using Shelly BLU gateways or Bluetooth-based automation
Cabinets, small access panels, and interior shutters where compact sensors are needed

How to use
Mount the sensor and magnet on the door/window and frame so that they align when closed, keeping the gap within the manufacturer’s recommended range. Insert the CR2032 battery observing polarity.

Once paired, test the sensor by opening and closing the door or window to confirm status updates are received in the app.
Usage recommendations
Place the sensor on interior doors and windows to avoid exposure to weather; keep the sensor within Bluetooth range of the controller for reliable communication. Replace the CR2032 battery when low-battery alerts appear in the app, and clean the mounting surfaces before installation to ensure secure adhesion or screw fixation.
