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:
{
"battery": 87,
"temperature": 21.6,
"humidity": 46.2,
"contact": true,
"battery_low": false,
"vibration": false,
"alarm_indicator": false,
"sensitivity_level": "low",
"temperature_offset": 0,
"humidity_offset": 0,
"reported_packages": 30000,
"rejoin_count": 30000,
"reboot_count": 30000,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"alarm_indicator":true}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"sensitivity_level":"medium"}'
Watch the topics live from the browser: MQTT client.
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: "Door opened"
mode: single
triggers:
- trigger: state
entity_id: binary_sensor.my_device_contact
to: "on"
actions:
- action: notify.notify
data:
message: "The door was opened"
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.
