Hello, i have an Element14 Pi Desktop case with a powerbutton on it.
I recently updated to LibreElec 12.0.1 and now my shutdownscript does not work anymore.
After some search i found that GPIO is not supported anymore and i need to switch to gpiozero.After a couple of hours fiddling around, trying to alter the script and even use chatGPT for coding help i gave up...
Anyone wants to help me in creating a working script?
My shutdown.py script used to look like this:
Python
Display More#!/usr/bin/python import sys sys.path.append('/storage/.kodi/addons/virtual.rpi-tools/lib') import RPi.GPIO as GPIO import time import os,sys import signal GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) GPIO.setup(31,GPIO.OUT) GPIO.setup(33,GPIO.IN) GPIO.output(31,GPIO.LOW) def shutdown_system(channels): os.system("sync") time.sleep(1) os.system("shutdown -h now") sys.exit() GPIO.add_event_detect(33,GPIO.RISING,callback=shutdown_system) while True: time.sleep(1)with the help of chatGPT i got this output to convert it to gpiozero:
Python
Display More#!/usr/bin/python import sys sys.path.append('/storage/.kodi/addons/virtual.rpi-tools/lib') from gpiozero import LED, Button from signal import pause import os import time # Stel de LED en de knop in met BCM pin nummering led = LED(6) # Fysieke pin 31 is BCM pin 6 button = Button(13) # Fysieke pin 33 is BCM pin 13 # Zet de LED uit led.off() # Definieer de shutdown functie def shutdown_system(): os.system("sync") time.sleep(1) os.system("shutdown -h now") sys.exit() # Koppel de shutdown functie aan de knop button.when_pressed = shutdown_system # Houd het script draaiende pause()But that gives errors in the debug log like:

I hope i'm not the only one using a hardware case for Raspberry Pi with a power button
