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,
"pressure_offset": 0,
"mains_voltage": 0,
"battery": 87,
"battery_low": false,
"uptime": 0,
"reading_interval": 185,
"tx_radio_power": "4dbm",
"smart_sleep": false,
"config_report_enable": false,
"comparison_previous_data": false,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
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}'

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.
