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:

{
  "presence": false,
  "illuminance": 120,
  "target_distance": 0,
  "radar_sensitivity": 5,
  "detection_range": 4,
  "shield_range": 4,
  "entry_sensitivity": 5,
  "entry_distance_indentation": 4,
  "entry_filter_time": 5,
  "departure_delay": 300,
  "block_time": 5,
  "breaker_status": false,
  "breaker_mode": "standard",
  "illuminance_threshold": 210,
  "linkquality": 120
}

Send commands to zigbee2mqtt/my_device/set:

mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"breaker_status":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"breaker_mode":"local"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"status_indication":"ON"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"sensor":"off"}'

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 on motion"
  mode: single
  triggers:
    - trigger: state
      entity_id: binary_sensor.my_device_presence
      to: "on"
  conditions:
    - condition: sun
      after: sunset
  actions:
    - action: light.turn_on
      target:
        entity_id: light.hallway

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.
