Driving plasma lights with python3

Support
1

Hi there

I am trying to drive my plasma light via python.
Goal: to read out rom_names and pass them to a python-script.

What does work with runcommand-onstart.sh:

  • getting rom name and passing it to the script
  • execute the py script

What does work with the python script:

  • parsing correct rom_name
  • driving buttons with rgb values (from single led to all of them)
  • driving buttons with animations
  • and more

BUT: as soon as I am trying to pass the arguments of the rom_name to the GPIO:14:15 with a rom_name.py that has the infos about RGB, i get an error that is something like this:

“invalid descriptor “name of the system””
i dont know where that comes from. i debugged for two days now …

is there anyone who could give me a fresh start?

Thanks a lot
