The MQTT client will publish updates to the given broker at the set topic.
--mqtt.enabled Enable MQTT publishing. [$MQTT_ENABLED]
--mqtt.broker= Set the host port and scheme of the MQTT broker. (default: tcp://localhost:1883) [$MQTT_BROKER]
--mqtt.client_id= Set the client ID for the MQTT connection. (default: interter-gui) [$MQTT_CLIENT_ID]
--mqtt.topic= Set the MQTT topic updates published to. (default: invertergui/updates) [$MQTT_TOPIC]
--mqtt.username= Set the MQTT username [$MQTT_USERNAME]
--mqtt.password= Set the MQTT password [$MQTT_PASSWORD]The MQTT client can be enabled by setting the environment variable MQTT_ENABLED=true or flag --mqtt.enabled.
All MQTT configuration can be done via flags or as environment variables.
The URI for the broker can be configured format should be scheme://host:port, where "scheme" is one of "tcp", "ssl", or "ws".
The intertergui application makes use of a serial tty device to monitor the Multiplus.
Example
-dev=/dev/ttyUSB0
The following configuration works for Nginx to allow the invertergui to be proxied.
When using a stand HTTP or HTTPS port to expose the gui:
location /invertergui {
return 302 /invertergui/;
}
location /invertergui/ {
proxy_pass http://localhost:8080/;
proxy_set_header Host $host;
}
location /invertergui/ws {
proxy_pass http://localhost:8080/ws;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_read_timeout 86400;
proxy_set_header Host $host;
proxy_set_header Referer $http_referer;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;
}When using a non-stand HTTP or HTTPS port to expose the gui change the HTTP Host description:
proxy_set_header Host $host:$server_port;The last four lines are optional, but is useful when debugging and logging connections:
proxy_set_header Referer $http_referer;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;This repos includes a Grafana dashboard in the grafana folder that you can import. This is useful if you are using prometheus to log your data and want to display it in a nice way.
