Hi guys!

Thanks for your hard work and great advances with this project.

I'm trying to run "pyPLC.py E S" in a raspberry without desktop and getting this message:

starting in EvseMode, simulated environment Traceback (most recent call last): File "/home/pi/myprogs/pyPlc/pyPlc.py", line 96, in <module> root = tk.Tk() ^^^^^^^ File "/usr/lib/python3.11/tkinter/__init__.py", line 2326, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ _tkinter.TclError: no display name and no $DISPLAY environment variable Do you faced this problem before? How can I run using this lite OS?

Thanks.

The pyPlc.py is the variant which is using the graphical user interface, with tkinter. This does not work on a display-less device. Instead, use the pevnogui or evsenogui variants. But I'm not sure whether they support the simulation mode.

Ok, no problem. Now I'm testing on Windows.
