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_front": "ON",
"brightness_front": 180,
"color_temp_front": 370,
"power_on_behavior_front": "off",
"effect_front": "blink",
"effect_speed_front": 1,
"state_back": "ON",
"brightness_back": 180,
"color_temp_back": 370,
"power_on_behavior_back": "off",
"gradient_scene_back": "blossom",
"effect_back": "blink",
"effect_speed_back": 1,
"gradient_style_back": "linear",
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state_front":"ON","brightness_front":180,"color_temp_front":370}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"color":{"hex":"#ff8800"}}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state_front":"OFF","transition":2}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"state_back":"ON","brightness_back":180,"color_temp_back":370}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"color":{"hex":"#ff8800"}}'

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: "Light at sunset"
mode: single
triggers:
- trigger: sun
event: sunset
offset: "-00:15:00"
actions:
- action: light.turn_on
target:
entity_id: light.my_device
data:
brightness_pct: 70
color_temp_kelvin: 2700

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.
