Help Required on BMW Plugin

[Filip]

Hi all,
Who will be able to help as this topics requires a bit deeper technical knowledge.
I developed a while ago the https://github.com/FilipDem/Domoticz-BMW-plugin, relying on the bimmer_connected library (https://github.com/bimmerconnected/bimmer_connected).

All works fine and seems to be used by multiple people.

The plugin needs a username/password to access the BMW Connected Drive (and some other data); all handled by the bimmer_connected library. In theory it would be possible to install twice the plugin in case two cars need to be managed. However we are getting into trouble as described by MadPatrick in https://github.com/FilipDem/Domoticz-BM ... 3146468947.

See the logs added by MadPatrick ("BMW" is one car; "Mini" is a second car):

Who would be able to give some hints on the problem? It stops on an "import" problem of the PyO3 modules ("do not yet support subinterpreters"). Probably because they are being imported a second time... Using only one plugin installation doesn't give this problem...
Would this be linked to the embedded python of Domoticz? Other ideas?

Thanks for your help!

Not a python programmer but to debug, is it possible to run a double session (in 2 terminal sessions) with the bimmer_connected library?
Just to test if the issue is in the Domoticz side or the bimner_connected side.
