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:
{
"brightness": 128,
"color_temp": 338,
"curtain_position": 50,
"assignment_status": "unassigned",
"base_group_id": 0,
"action_button": 3,
"action_group": 0,
"bind_all_scene": "bind",
"bind_all_light": "bind",
"bind_all_curtain": "bind",
"assign_button_1": "assign",
"set_base_group_id": 32501,
"linkquality": 120
}
The device only reports data and takes no commands.

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: "Button"
mode: single
triggers:
- trigger: mqtt
topic: zigbee2mqtt/my_device
value_template: "{{ value_json.action }}"
payload: "scene_1"
actions:
- action: light.toggle
target:
entity_id: light.living_room
Check the YAML: YAML checker.
How to pair it
- In Zigbee2MQTT click Permit join.
- 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.
- Keep the device close to the coordinator or a router while pairing.
- 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.
