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:
{
"noise": 0,
"noise_detected": false,
"noise_status": "no_noise",
"noise_state": "noise",
"report_mode": "collect_noise_floor",
"noise_lower_limit": 30,
"noise_upper_limit": 55,
"collect_time": 50,
"noise_hold_time": 150,
"noise_delay": 150,
"report_threshold": "1_db",
"indicator": false,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"report_mode":"realtime"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"report_threshold":"3_db"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"indicator":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.
