Weird Errors in PyViCare.py #343

Closed E-niek closed 6 months ago

E-niek commented 6 months ago

I have the PyViCare API Plugin in Domoticz (in Docker). I works fine, but if I disable the plugin, and then enable it again, I see weird errors, like this:

if I, after seeing this, restart domoticz, from docker, it works fine with no errors. But this isn't nice, because now I can't disable the plugin, and enable it back on, without having to restart domoticz.

Hope you can help me.

@E-niek I'm not aware how domoticz is using PyViCare. PyViCare itself does not have a globale state, that means the issue is in domoticz not cleaning up everything correctly. I currently don't see anything we can do here.
