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:
{
"current_heating_setpoint": 21,
"local_temperature": 20.5,
"display_temperature": 0,
"temperature_offset": 0,
"humidity": 46.2,
"humidity_offset": 0,
"co2": 640,
"co2_offset": 0,
"display_brightness": 5,
"language": "french",
"temperature_unit": "celsius",
"humidity_display": "hidden",
"co2_display": "hidden",
"display_temperature_source": "temperature_1",
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"current_heating_setpoint":21.5}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"language":"english"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"temperature_unit":"fahrenheit"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"humidity_display":"shown"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"co2_display":"shown"}'

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: "Cooler at night"
mode: single
triggers:
- trigger: time
at: "23:00:00"
actions:
- action: climate.set_temperature
target:
entity_id: climate.my_device
data:
temperature: 18
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.
