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:

{
  "battery": 87,
  "state": "ON",
  "child_lock": false,
  "valve_abnormal_state": "normal",
  "water_flow_unit": "liter",
  "irrigation_duration": 360,
  "irrigation_mode": "duration",
  "irrigation_amount": 5000,
  "fail_safe": 360,
  "actual_irrigation_amount": 0,
  "real_time_irrigation_duration": 0,
  "real_time_irrigation_volume": 0,
  "hour_irrigation_duration": 0,
  "hour_irrigation_volume": 0,
  "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 '{"child_lock":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"water_flow_unit":"us_gallon"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"irrigation_mode":"capacity"}'

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: "Off at night"
  mode: single
  triggers:
    - trigger: time
      at: "23:30:00"
  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.
