Try this matey - it was based on William Hofferbert’s code(he’s on here somewhere as whofferbert I think).
I took his rotary encoder code and added some GPIO button event triggers for button input.
Check his original gihub repo out that’s in the comments of the code, as it details the permissions to run it as SUDO without password on startup
