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:

{
  "card": false,
  "battery_low": false,
  "linkquality": 120
}

The device only reports data and takes no commands.

Watch the topics live from the browser: MQTT client.

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.
