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:
{
"occupancy": false,
"illuminance": 120,
"target_distance": 0,
"radar_sensitivity": 55,
"detection_range": 4,
"shield_range": 4,
"entry_sensitivity": 55,
"entry_distance": 4,
"entry_filter_time": 0,
"departure_delay": 3603,
"block_time": 5,
"status_indication": "OFF",
"sensor": "on",
"scene_preset": "Custom",
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"status_indication":"ON"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"sensor":"occupied"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"scene_preset":"Toilet"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"distance_report_mode":"Occupancy detection"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"debug_mode":"ON"}'

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 on motion"
mode: single
triggers:
- trigger: state
entity_id: binary_sensor.my_device_occupancy
to: "on"
conditions:
- condition: sun
after: sunset
actions:
- action: light.turn_on
target:
entity_id: light.hallway
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.
