Screen blanking and Shutdownscript

[Aut0mat3d]

Hi There!
Found a neat Script here: https://retropie.org.uk/forum/post/148439
Thanks @QuixoticDev

I modified the Script to look for additional Controllers and to shut down the Pi after a customizeable Period.

Perhaps it is useable for anyone - so here is the Moified Script:

#!/bin/bash
#=============================================================
# Title        : idle-screenoff.sh
#
# Description  : Power off the display when idle
#                - Detects idle by monitoring joystick input
# Base-Script:
# Author       : QuixoticDev
# Version      : v1.0 - 05/23/2018
#
# Extended and modified by: Aut0mat3d 
# Version      : v1.1e - 02/06/2024

# inputWindow = Time window (s) to monitor the device for input
# - Check for input in a 5 second window
inputWindow=2
 
# inputCount = How many inputs constitute activity + 1

Place it (as the originial) under /home/pi/idle-screenoff.sh
and make it executeable with chmod +x

In the Script you have to modify the Script which has to be run for powering off the Pi.
Modify this Line to your needs:

powerOffCommand="/opt/retroflag-picase/shutdown.sh power"

I run the Script before ES starts.
Here is my /opt/retropie/configs/all/autostart.sh

        /home/pi/idle-screenoff.sh &
        emulationstation #auto

I hope someone does have a Use for that.
If you reply here, i cant guarantee to reply or react as i am chronically ill and disabled.

All the Best, and Thanks for Retropie and ES
