Aqara Door and Window Sensor Trio Bundle

1. Align the primary sensor and the magnet according to the mounting line as shown in the user manual. Attach the primary sensor to the fixed surface and the magnet to the surface that will be opened.
2. The primary sensor and the magnet should be less than 22mm apart.
3. The exact position can vary, but make sure that the primary sensor and the magnet are aligned upon installation.
4. Because of the complex nature of an indoor environment, adjusting the position of the sensor hub with the Door and Window Sensor can improve the overall result.
5. Ensure you avoid installing sensors on metal surfaces because of the adverse effect this can have on the signal.

Rotate the magnet 90 degrees. It is better to install the sensor on a fixed door frame. Attaching the small magnet to the door is the best way to protect the sensor. Although the primary Door and Window Sensor should be less than 22mm from the magnet, they should not be installed too close together this is to ensure they are not in contact and therefore avoid the damage that could occur if they are knocked to the ground.

In a complex indoor environment, This distance will need to be reduced if there is a wall between them to ensure good connectivity.

Possible reason:

1. There has been an operation error. Try to add the device according to the adding method again.
2. The device is too far from the Hub. Try to move the device closer to the Hub.
3. There are too many devices under the Hub.

1. Using the eject pin, push the reset hole of the Door and Window Sensor . If the Hub makes voice prompts, “Normal link confirmed”, it signifies that the Hub and the Door and Window Sensor are communicating properly. Go to ②; If there is no voice prompts, move the sensor closer to the Hub and try again. If there is still no voice prompt, the sensor might be deleted or it might run out of battery. Please refer to the device adding methods to add the device or replace the battery.
2. Move the sensor closer to the magnet unit and move away from the magnet for 2 or 3 times. Enter the home of Door and Window Sensor in the Aqara Home app, refresh the device records (log). If there is related log, it indicates the device works properly.

1. Aqara Door and Window Sensor can be installed on the door or window to detect door and window status (open and closed).
2. The Door and Window sensor works with other smart devices. If it detects that the door/window opens or closes, it triggers other devices to turn on or off home appliances or to take other actions.

1. The sensor unit and magnet unit might be too far away from each other. Ccheck the distance between them and ensure the distance is no more than 22mm.
2. The Hub might be too far away from the sensor. Make sure the gap between the sensor unit and the magnet unit is no more than 22mm. Press the reset hole with the eject pin at your desired location. If the Hub makes voice prompts, it indicates the Hub is communicating correctly with the sensor. If not, move the sensor closer to the Hub.

1. Push in and hold the reset hole on the device for 3 seconds. The indicator light will flash 3 times before resetting to factory settings.
2. If a sensor needs to be paired with another sensor hub, it will need to be reset before the new pairing will work effectively.

Possible reasons:

1. The accessory is too far away from the Hub, try to reduce the distance between the sensor and the hub.
2. Low battery or dead battery. Replace the battery and try again.
3. The accessory is installed on the metal surface and the signal is interfered. Try to avoid installation on metal surfaces.
