I see what you did, i made a similar change now in the repository (but gives a bit more info tot the API Error field). I cannot test, since i never have this issue, so please update your plugin to the latest code and let me know the results...

Could you switch on debugging and post the full plug-in logging?

Btw: this is all just attacking the symptoms. Your real issue is that you have connectivity issues. Are you still working on that?

EDIT:
Just to be safe, i made some handling around this division... so pls upgrade to latest version.

My remark on the connection issue still stands, now in some connection error cases it will now report some sensors to 0 instead of the real value, cause due to the connection issue which prevents it from getting data. So you get less errors in the log, but your issue is not solved

[mvveelen]

I've updated just now, but I don't know why there are connectivity issues like you say. The NUC is connected by wire and I have a fast internet connection via KPN (glass). Could it be that I poll the server too often? I've got the interval set to every 60 seconds.

[akamming]

I've migrated my Domoticz installation from a Raspberry Pi 3B+ to a NUC. Everything is working fine now, also the Volvo plugin.

But.

Once in a while I see a bunch of errors although the plugin is working fine.
What can be the cause of it and....what could be the solution to prevent these errors (which I didn't have on my RPi)? I could, of course, switch off error logging, but that's not a solution.

Update interval is (unchanged): 60

It's this logging what start this, The "ConnectionResetError: [Errno 104] Connection reset by peer" is the actual error which happens on your system.

This means that something (the “peer”) abruptly closes the TCP connection while your the plugin was trying to read or write data.

The domoticz Python plugin is making an HTTPS request to the Volvo API, The Volvo server (or something in between) sent a TCP RST packet, forcefully ending the connection. So the reset does not happens in Domoticz or Python.

I've asked chatgpt, and 2 possible causes:
- TLS/SSL issues (Some APIs require modern TLS versions or SNI support. Outdated Python versions or requests libraries can fail to negotiate properly.)
- or a router, proxy, or firewall might reset idle or long-running connections.

No errors since the latest update. Yet.

Edit: ik zag zojuist dat de NUC de netwerkverbinding mocht sluiten (auto), dat heb ik aangepast naar ON. Misschien lag daar wel de oorzaak....
