#!/bin/bash

# Script for hyperion which allows you to turn off your LEDs when your AVR is off and vice versa.
# Tested with Raspian on an RPi3
# 1 - Plug your RPi with an HDMI cable TV/AVR/...
# 2 - Copy the script on your RPi
# 3 - Run sudo chmod +x on the script
# 4 - To make it run at startup, add   @reboot /your/path/yourscriptname.sh    to crontab -e
# 5 - Enjoy
