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,
"sound_volume": "silent_mode",
"voltage": 2950,
"last_unlock_source": "zigbee",
"last_lock_source": "zigbee",
"auto_relock": false,
"auto_relock_time": 0,
"num_pin_users": 0,
"min_pin_length": 0,
"max_pin_length": 0,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"sound_volume":"low_volume"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"auto_relock":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.
