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.

Binding #

The E1743 can be bound to groups using binding. It can only be bound to 1 group at a time and cannot be bound to a device.

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"}. Right before executing the commands make sure to wake up the device by pressing a button on it.

Battery Replacement #

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

Device type specific configuration #

How to use device type specific configuration

• legacy: Set to false to disable the legacy integration (highly recommended!) (default: true)

• simulated_brightness: Set to true to simulate a brightness value (default: false). If this device provides a brightness_move_up or brightness_move_down action it is possible to specify the update interval and delta. This can be done by instead of specifying true:

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

OTA updates #

This device supports OTA updates, for more information see OTA updates.

Battery (numeric) #

Remaining battery in %. Value can be found in the published state on the battery property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 100. The unit of this value is %.

Action (enum) #

Triggered action (e.g. a button click). Value can be found in the published state on the action property. It’s not possible to read (/get) or write (/set) this value. The possible values are: on, off, brightness_move_down, brightness_move_up, brightness_stop.

Linkquality (numeric) #

Link quality (signal strength). Value can be found in the published state on the linkquality property. It’s not possible to read (/get) or write (/set) this value. The minimal value is 0 and the maximum value is 255. The unit of this value is lqi.

Manual Home Assistant configuration #

Although Home Assistant integration through MQTT discovery is preferred, manual integration is possible with the following configuration:

  - platform: "mqtt"
    state_topic: "zigbee2mqtt/<FRIENDLY_NAME>"
    availability_topic: "zigbee2mqtt/bridge/state"
