Hello guys! I've made a little script to turn off my LEDs when my AVR turns off and vice versa. It uses the CEC-Client, so it should work with everyone as long as your devices are HDMI-CEC compliant. The instructions to install it are included in the top part of the script. It's a pretty simple script so it shouldn't be a big deal to make it work. PHP: #!/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 on your 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# RaPiiDeremotePath="hyperion-remote"isOn=-1while :do # We get the CEC status status=$(echo pow 0 | timeout 5 cec-client -d 1 -s) # If it's off and it wasn't already, let's turn off the LEDS if [[ "$status" == *"power status: standby"* ]] && [[ "$isOn" != "0" ]] then eval "$remotePath --priority 0 --color black" isOn=0 # If it's on and it wasn't already, let's turn on the LEDS elif [[ "$status" == *"power status: on"* ]] && [[ "$isOn" != "1" ]] then eval "$remotePath --clearall" isOn=1 fi sleep 2done Have fun!
