Reconnect after connection loss

[chheiss]

Hi! Not sure if I had asked before, but it would be really great to get the plugin to reconnect after a few minutes, when there has been a connection drop. Thanks!

[CyberDNS]

Hi, does the connection drop on Lupusec system or homeassistant MQTT?

[chheiss]

Lupusec system is disconnected for a few seconds every few hours. Mqtt stays connected all the time.

[CyberDNS]

Do you see some kind of exception in the logs when the disconnection occurs or after the disconnection during the next poll?

[chheiss]

No, as I don't know when exactly the disconnect occurs, it is once every 24h. When I restart the plugin, it works again.

hey, I have exactly the same problem. The addon loses the connection every 24 hours! After restarting the addon everything works fine again.

The latest version of HA, MQTT and your addon is installed in use.

[CyberDNS]

Hi, Do you get after the disconnection still those messages or not?

[19:38:59 INF] Polling... (Every 5th cycle is logged) {"SourceContext": "Lupusec2Mqtt.Lupusec.PollingHostedService"}

And after disconnection, you have no errors/exceptions in the logs? Best regards, David

[CyberDNS]

And set this value in the config to Debug.

[allgrinder]

Thanks! I set it up that way now. Nevertheless, I have had a stable connection for 4 days. As soon as there are problems again - I'll post the log

Hi, same problem for me with following in lupusec-addon protocoll:

These are not IP addresses from my IP range as they occur in my network. If I restart Mosquitto first and then Lupusec Addon, everything works again for a while.

Hi @xsus95 ,

Thanks for the exception message, I think this helps to identify the problem. I will investigate this during the next days if I have the time.

Best regards, David

@CyberDNS

Hey, Yesterday I disconnected the network connection for a short time. However, there was no message in the Lupus Addon afterwards. In the Mosuqitto log, however, I still have these messages as already written now permanently. BUT: The connection is still running and hassio gets all changes of the states of my Lupus sensors. So a short interruption of the connection can not necessarily be the cause... I am confused.

[CyberDNS]

I will close this issue.

If it is still present in the current version, please open a new issue.
