2. Magnetically attach the device to the plate.

Install the device in the desired place, then press the Pairing button on the device. The LED indicator flashes twice means the device and the device under the same Zigbee network (the router device or hub) are in the effective communication distance.

FAQ

1. Are single press, double press, and long press still supported when added to other platforms via the Matter Bridge?

All three actions are supported when added to the Apple ecosystem via Matter Bridge. On other platforms, currently only single press is supported.

​

Troubleshooting

1. The sensor is not being discovered by the Zigbee hub?

Ensure the CR2477 battery is correctly installed and not depleted.

Press and hold the pairing button for 5 seconds until the LED indicator blinks to enter pairing mode.

Make sure the hub is in pairing mode.

Bring the sensor closer to the hub during pairing.

If it still fails, reset the sensor (press and hold the button for 10 seconds) and try again.

2. Double-click action may not be recognized properly.

To ensure proper recognition of a "double-click," make sure the interval between the two presses is less than 0.5 seconds.

3. The battery drains too quickly.

Check if the device is frequently losing Zigbee connection, which may cause high power usage.

Make sure your Zigbee network has adequate signal strength—consider adding a Zigbee router/repeater.

Avoid frequent re-pairing or unnecessary automation triggers
