4.3. Device Pairing

- The app will search for and connect to the sensor. Once connected, you can name your sensor and assign it to a room.
4.4. Mounting the Sensor
The sensor uses adhesive for tool-free installation. For optimal performance, ensure the main sensor unit and the secondary magnet unit are aligned correctly and placed within 1 cm (0.4 inches) of each other when the door/window is closed.
- Clean the surface where you intend to mount the sensor. Ensure it is dry and free of dust or grease.
- Peel the backing from the adhesive pads and attach them to the back of both the main sensor unit and the secondary magnet unit.
- Mount the main sensor unit on the fixed frame of the door or window.
- Mount the secondary magnet unit on the moving part of the door or window, aligning it with the alignment arrow on the main sensor unit. Ensure the gap between the two parts is minimal when the door/window is closed.
- Test the installation by opening and closing the door/window. Verify that the sensor status updates in the Geeni app.
