Testing with Logarex LK13BE606739 and RS485

[Blowfly69]

Actually, it looks that this is exactly the piece of software I'd need to connect my new LK13BE606739 power meters (3 of them) via RS485 on a Raspi 2B with Home Assistant and I'd love to test it.
Unfortunately, I'm already failing with installation. poetry install takes forever (no progress for hours), obviously there is an issue with installing pyparsing :

My active coding time ended with Delphi a long time ago, so I'm not really familiar with modern concepts and languages like Python. Chances are high that I missed or did something wrong. But after some recherching it looks like there is a common issue poetry has with resolving of dependencies. Do you have a hint what I might be doing wrong or what to do?
Thanks a lot!

I now got it running, but there is an error with mqtt popping up, preventing further exeution:

Setting mqtt_enabled to false in the config didn't help. Any idea? Thank you!

Her my config file (parity ="N" quotes were necessary, they were missing in the demo config).
