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:
{
"alarm_state": "normal",
"volume": "low",
"duration": 905,
"melody": "doorbell",
"night_light": false,
"light_mode": "breathing",
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"alarm_state":"alarm_sound"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"volume":"medium"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"melody":"alarm_1"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"night_light":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"light_mode":"red_flash"}'

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.
