Button erstellt und er soll auch schalten Button created and he should also swit

The material overlay text is set in a method in qtplasmac_handler.py named get_overlay_text, you could patch that similar to how power_state is patched in qtplasmac_custom.py and just remove the line if self.pmx485Exists:

The label with 'ON' is created as l1 = QLabel('ON'), you could rename it self.some_name and change wherever l1 appears to the new name. Then the text could be set anywhere with self.some_name.setText('NEW TEXT')

I modified the last custom code that you posted:
The label is named self.pwmgn_label.
I have also added cut amps to the overlay in a more simple way than I described earlier.
All the changes are commented.
 

Hallo phillc54
my heartfelt thanks again
I wouldn't have been able to do that with my limited programming knowledge.
yes, everything works also the highlights ( the on..off , and the cut amps )
