| mqtt:
broker: localhost
port: 1883
client_id: home-assistant-1
username: !secret mqtt_username
password: !secret mqtt_password
|
設完重啟HA就可以了。
第四步 測試
首先可以看看服務狀態：
1
| sudo systemctl status mosquitto
|
若要debug，也可以
1
| sudo tail -f /var/log/mosquitto/mosquitto.log
|
Cli測試
打開2個terminal，一個將是publisher; 另一個是subscriber。
subscriber方，來接收這個topic:
1
| mosquitto_sub -h localhost -t "sensor/temperature" -u username -P password
|
publisher方，發佈topic:
1
| mosquitto_pub -h localhost -t "sensor/temperature" -m 22.5 -u username -P password
|
HA服務測試
HA若有成功設置mqtt，會有 mqtt.publish 的服務可呼叫。
