Thanks

Please take care of clean shutdown (library does not keep any open timers as this might break compact mode) and handling of response timemouts

And please check the benefits of an external library compared to existing code too. What oeoblems will ve fixed vy the change?

External might reduce maintainance effort

But problems at external code can be fixed by external dev only.

And this adapter us secztity relevant. Passing username and password to an external libray could be a security risk. I suggest to discuss with @Apollon77 especialky if the extetbal library us not widely used.
