MQTT: state and commands

Zigbee2MQTT publishes the device state to zigbee2mqtt/my_device (my_device is the name you give the device). An example message:

{
  "state": "ON",
  "brightness": 180,
  "color_temp": 370,
  "local_temperature": 20.5,
  "current_heating_setpoint": 21,
  "system_mode": "heat",
  "heater_power": false,
  "operating_mode": "off",
  "night_light_mode": false,
  "mute_prompt_tone": false,
  "constant_temperature_mode": false,
  "linkquality": 120
}

Send commands to zigbee2mqtt/my_device/set:

mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state":"ON","brightness":180,"color_temp":370}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state":"OFF","transition":2}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"current_heating_setpoint":21.5}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"system_mode":"heat"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"operating_mode":"warm"}'

Home Assistant automation example

Zigbee2MQTT creates Home Assistant entities from the device name. If it is called my_device, an automation in automations.yaml can look like this:

- alias: "Light at sunset"
  mode: single
  triggers:
    - trigger: sun
      event: sunset
      offset: "-00:15:00"
  actions:
    - action: light.turn_on
      target:
        entity_id: light.my_device
      data:
        brightness_pct: 70
        color_temp_kelvin: 2700

Check the YAML: YAML checker.

How to pair it

  1. In Zigbee2MQTT click Permit join.
  2. Put the device in pairing mode: usually a long press of the reset button (5–10 s) until the LED blinks; bulbs: switch the power off and on 5–6 times.
  3. Keep the device close to the coordinator or a router while pairing.
  4. Give it a clear name: MQTT topics and Home Assistant entities are built from it.

Exact procedure and model notes: the device page in the Zigbee2MQTT docs. No coordinator yet: coordinator picker.
