Notes

Deprecated click event

By default this device exposes a deprecated click event. It's recommended to use the action event instead.

To disable the click event, set legacy: false for this device in configuration.yaml. Example:

devices:
  '0x12345678':
    friendly_name: my_device
    legacy: false

Pairing

Pair the switch to Zigbee2MQTT by pressing the pair button (found under the back cover next to the battery) 4 times in a row. The red light on the front side should flash a few times and then turn off (it's more visible to see the light from the back). After a few seconds it turns back on and pulsate. When connected, the light turns off.

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 functionallity of this remote varies per firmware version:

• below 2.3.075: 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

Battery Replacement

After replacing the battery, reporting of battery % may not work. If you experience this issue, remove the device and join it again.

OTA updates

This device supports OTA updates.

Options

• legacy: Set to false to disable the legacy integration (highly recommended), will change structure of the published payload (default true). The value must be true or false

• simulated_brightness: Simulate a brightness value. If this device provides a brightness_move_up or brightness_move_down action it is possible to specify the update interval and delta. The action_brightness_delta indicates the delta for each interval. Example:

simulated_brightness:
  delta: 20 # delta per interval, default = 20
  interval: 200 # interval in milliseconds, default = 200
