What is the problem?
The SPI GPIO-Pin "10" is already in use (Touchscreen)
In order to use the "RGB Status" plugin, i would need to connect the data pin to GPIO10, or run octoprint as root (to use another GPIO Pin)
What did you already try to solve it?
Tried to add the "pi" user to "gpio"-Group -> already is.
I tried to run octoprint as root, but I am not really sure how to do so.
