Device type specific configuration #

How to use device type specific configuration

• transition: Controls the transition time (in seconds) of on/off, brightness, color temperature (if applicable) and color (if applicable) changes. Defaults to 0 (no transition). Note that this value is overridden if a transition value is present in the MQTT command payload.

Exposes #

Light #

This light supports the following features: state, brightness.

• state: To control the state publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"state": "ON"}, {"state": "OFF"} or {"state": "TOGGLE"}. To read the state send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"state": ""}.
• brightness: To control the brightness publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"brightness": VALUE} where VALUE is a number between 0 and 254. To read the brightness send a message to zigbee2mqtt/FRIENDLY_NAME/get with payload {"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":0.5}.

Moving/stepping #

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

• move: this will automatically move the value over time, to stop send value stop or 0.
• step: this will increment/decrement the current value by the given one.

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
}

Effect (enum) #

Triggers an effect on the light (e.g. make light blink for a few seconds). Value will not be published in the state. It’s not possible to read (/get) this value. To write (/set) a value publish a message to topic zigbee2mqtt/FRIENDLY_NAME/set with payload {"effect": NEW_VALUE}. The possible values are: blink, breathe, okay, channel_change, finish_effect, stop_effect.

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
    color_temp: false
    xy: false
    hs: false
    schema: "json"
    command_topic: "zigbee2mqtt/<FRIENDLY_NAME>/set"
    brightness_scale: 254
    effect: true
    effect_list: 
      - "blink"
      - "breathe"
      - "okay"
      - "channel_change"
      - "finish_effect"
      - "stop_effect"

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