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,
"voltage": 2950,
"temperature": 21.6,
"humidity": 46.2,
"temperature_offset": 0,
"humidity_offset": 0,
"read_interval": 303,
"enabling_repeat_command": false,
"enabling_temperature_control": false,
"low_temperature": 43,
"high_temperature": 43,
"temperature_actions_1": "heat",
"enabling_humidity_control": false,
"low_humidity": 51,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"enabling_repeat_command":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"enabling_temperature_control":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"temperature_actions_1":"cool"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"enabling_humidity_control":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"humidity_actions_2":"dry"}'

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: "Room too warm"
mode: single
triggers:
- trigger: numeric_state
entity_id: sensor.my_device_temperature
above: 26
for: "00:10:00"
actions:
- action: notify.notify
data:
message: "Temperature above 26 °C"
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.
