Question: How to use different serial port than ttyUSB0? #13

Can I tell pylontech.py to use e.g. ttyUSB11 instead of ttyUSB0? Everything is working fine except my USB devices (I have multiple) are differently enumerated...

Hi, You can specify the serial port in the constructor: https://github.com/Frankkkkk/python-pylontech/blob/master/pylontech/pylontech.py#L112

Cheers

Thank you for your reply (and your perfectly working project) - but this breaks pip upgrade/update functionality. After an upgrade via pip changes are lost...

Frankkkkk commented 2 years ago

I don't understand; how do you use the library ? In your code, you should have something like:

p = Pylontech(serial_port='/dev/ttyUSB11')
…

And that shouldn't break when updating via pip ‽ Cheers

The issue is not at your side - it is at my side. I do not have experiences with python and do not want to poke in pylontech.py. This answer rescues my day - thank you!
