Picture

Pair the remote to Zigbee2MQTT by holding it close to the coordinator and pressing the inside button, next to the CR2032 battery, 4 times. The red light on the (front of the) remote will now flash a few times.

Troubleshooting: Device didn't respond to OTA request

To resolve the Device didn't respond to OTA request error, you can try to push a button on it, shortly before you start the update, to wake up the Remote. Sometimes it also helps keeping the device awake, by pushing a button repeatedly until you read the first "Updating... 0.00%" message (about 5s).

Binding

The binding functionality of this remote varies per firmware version:

below 2.3.75: suppports binding to groups only. It can only be bound to 1 group at a time. By default this remote is bound to the default bind group which you first have to unbind it from. This can be done by sending to zigbee2mqtt/bridge/request/device/unbind payload {"from": "DEVICE_FRIENDLY_NAME", "to": "default_bind_group"}. Wake up the device right before sending the commands by pressing a button on it.
2.3.075 and greater: supports binding to devices only

Troubleshooting: no battery level

It may help to remove the battery for a few seconds and after that reconfigure it via Configure. Right before executing the Configure make sure to wake up the device by pressing a button on it.
