Device type specific configuration #

How to use device type specific configuration

Model numbers #

Model number depends on the country and the colour of the devices, for instance:

Other brand names depending on the country:

LED configuration #

Example of MQTT message payload to disable permanent LED and enable LED when the lights are on. This should be sent to zigbee2mqtt/FRIENDLY_NAME/set:

{
    "permanent_led": "OFF",
    "led_when_on": "ON"
}

Dimmer #

Example of MQTT message payload to enable dimming. This should be sent to zigbee2mqtt/FRIENDLY_NAME/set:

{
    "dimmer_enabled": "ON"
}

Identify #

Helps to identify the switch using the LED.

Example of MQTT message payload to Identify the switch. This should be sent to zigbee2mqtt/FRIENDLY_NAME/set:

{
  "identify": {
    "effect": "blink3",
    "color": "white"
  }
}

Exposes #

Light #

This light supports the following features: state, brightness.

Transition #

For all of the above mentioned features it is possible to do a transition of the value over time. To do this add an additional property transition to the payload which is the transition time in seconds. Examples: {"brightness":156,"transition":3}, {"color_temp":241,"transition":1}.

Moving/stepping #

Instead of setting a value (e.g. brightness) directly it is also possible to:

The direction of move and step can be either up or down, provide a negative value to move/step down, a positive value to move/step up. To do this send a payload like below to zigbee2mqtt/FRIENDLY_NAME/set

NOTE: brightness move/step will stop at the minimum brightness and won’t turn on the light when it’s off. In this case use brightness_move_onoff/brightness_step_onoff

{
  "brightness_move": -40, // Starts moving brightness down at 40 units per second
  "brightness_move": 0, // Stop moving brightness
  "brightness_step": 40 // Increases brightness by 40
}

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:

light:
  - platform: "mqtt"
    state_topic: "zigbee2mqtt/<FRIENDLY_NAME>"
    availability_topic: "zigbee2mqtt/bridge/state"
    brightness: true
    schema: "json"
    command_topic: "zigbee2mqtt/<FRIENDLY_NAME>/set"
    brightness_scale: 254

sensor:
  - platform: "mqtt"
    state_topic: "zigbee2mqtt/<FRIENDLY_NAME>"
    availability_topic: "zigbee2mqtt/bridge/state"
    value_template: "{{ value_json.linkquality }}"
    unit_of_measurement: "lqi"
    enabled_by_default: false
    icon: "mdi:signal"
    state_class: "measurement"
