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:
{
"pressure": 1012,
"bar": 0,
"psi": 0,
"temperature": 21.6,
"pressure_offset": 0,
"raw_temperature_calibration": 0,
"raw_temperature": 0,
"raw_temperature_recalibrated": 0,
"range": "0-10 Bar",
"battery": 87,
"voltage": 2950,
"battery_low": false,
"uptime": 0,
"reading_interval": 155,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"range":"0-16 Bar"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"tx_radio_power":"19dbm"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"smart_sleep":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"config_report_enable":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"comparison_previous_data":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: "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.
