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:

{
  "temperature": 21.6,
  "temperature_threshold": 70,
  "temperature_breaker": false,
  "power_threshold": 14,
  "power_breaker": false,
  "over_current_threshold": 33,
  "over_current_breaker": false,
  "over_voltage_threshold": 178,
  "over_voltage_breaker": false,
  "under_voltage_threshold": 158,
  "under_voltage_breaker": false,
  "state": "ON",
  "countdown": 21600,
  "power_outage_memory": "on",
  "linkquality": 120
}

Send commands to zigbee2mqtt/my_device/set:

mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state":"TOGGLE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"temperature_breaker":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"power_breaker":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"over_current_breaker":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"over_voltage_breaker":true}'

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: "Turn off when idle"
  mode: single
  triggers:
    - trigger: numeric_state
      entity_id: sensor.my_device_power
      below: 2
      for: "00:15:00"
  actions:
    - action: switch.turn_off
      target:
        entity_id: switch.my_device

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.
