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:
{
"water_consumed": 0,
"monthly_water_consumption": 0,
"daily_water_consumption": 0,
"report_period": "1h",
"prepayment_switch": false,
"cumulative_heat": 0,
"instantaneous_flow_rate": 0,
"inlet_water_temperature": 0,
"outlet_water_temperature": 0,
"voltage": 230,
"linkquality": 120
}
Send commands to zigbee2mqtt/my_device/set:
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"report_period":"2h"}'
mosquitto_pub -t zigbee2mqtt/my_device/set -m '{"prepayment_switch":true}'
Watch the topics live from the browser: MQTT client.
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.
