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",
"state_l3": "ON",
"brightness_1": 505,
"brightness_min_1": 505,
"brightness_max_1": 505,
"countdown_1": 43200,
"brightness_2": 505,
"brightness_min_2": 505,
"brightness_max_2": 505,
"countdown_2": 43200,
"relay_status": "off",
"brightness_3": 505,
"brightness_min_3": 505,
"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 '{"state_l3":"TOGGLE"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"relay_status":"on"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"light_mode":"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: "Off at night"
mode: single
triggers:
- trigger: time
at: "23:30:00"
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.
