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:

{
  "limits_calibration": "start",
  "automatic_calibration": "calibrate",
  "state": "OPEN",
  "curtain_speed": 51,
  "manual_open_close": false,
  "adaptive_pulling_speed": false,
  "manual_stop": false,
  "reverse_direction": false,
  "status": "closing",
  "last_manual_operation": "open",
  "curtain_position": 51,
  "traverse_time": 0,
  "calibration_status": "not_calibrated",
  "calibrated": false,
  "linkquality": 120
}

Send commands to zigbee2mqtt/my_device/set:

mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state":"CLOSE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"limits_calibration":"end"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"manual_open_close":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"adaptive_pulling_speed":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"manual_stop":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: "Open the curtains in the morning"
  mode: single
  triggers:
    - trigger: time
      at: "07:30:00"
  actions:
    - action: cover.open_cover
      target:
        entity_id: cover.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.
