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:
{
"state_l1": "ON",
"state_l2": "ON",
"power": 12.4,
"current": 0.06,
"energy": 3.21,
"voltage": 230,
"device_temperature": 31,
"switch_type": "toggle",
"power_on_behavior": "on",
"operation_mode_l1": "decoupled",
"operation_mode_l2": "decoupled",
"interlock": false,
"mode": "power",
"pulse_length": 1100,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state_l1":"TOGGLE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state_l2":"TOGGLE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"switch_type":"momentary"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"power_on_behavior":"previous"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"operation_mode_l1":"control_relay"}'

Home Assistant automation example
Zigbee2MQTT creates Home Assistant entities from the device name. If it is called my_device, an automation in automations.yaml can look like this:
- alias: "Turn off when idle"
mode: single
triggers:
- trigger: numeric_state
entity_id: sensor.my_device_power
below: 2
for: "00:15:00"
actions:
- action: switch.turn_off
target:
entity_id: switch.my_device_l1
Check the YAML: YAML checker.
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.
