• Enable gpio-ir on GPIO port 18

  mount -o remount,rw /flash
  echo "dtoverlay=gpio-ir,gpio_pin=18" >> /flash/config.txt
  

• Get codes sent by IR remote

  ir-keytable -p all -t

• Configure keymap to be used persistently

  cat /storage/.config/rc_maps.cfg
  * * custom_remote
  

• Configure irexec

  cat /storage/.lircrc 
  begin
    prog = irexec
    button = KEY_BLUE
    config = kodi-send --action='RunScript("/storage/scripts/toggle-lifx.py")'
  end
  

• Add irexec to autostart.sh

  cat /storage/.config/autostart.sh
  /usr/bin/irexec -d
