Setup/Configuration for another Magic Mirror

Note: Unfortunately, a glitch from the TV, which sometimes occurred before, seems now to be manifested. The TV doesn't power on anymore, neither using remote control nor buttons. I couldn't find a faulty component on TV circuit board. I will/have to stop this project. However, I have learned a lot, so it was not wasted time. 

General setup

  • Raspberry PI 2
  • SEG ArtColor TV 
  • PIR module (GPIO 17, 18), IR transmitter (GPIO 4)
The PIR module will detect motion. If a motion is sense the TV will be switched on via the IR transmitter (simulation of IR remote). After a predefined timeout periode without further motion the TV will switched off (to standby).

Install and enable lirc

  • install lirc
    sudo apt-get install lirc
  • enable lirc module - edit /boot/config.txt
    dtoverlay=lirc-rpi,gpio_out_pin=4,gpio_in_pin=22
  • configure lirc - edit /etc/lirc/hardware.conf
    LIRCD_ARGS=""
    ...
    DRIVER="default"
    DEVICE="/dev/lirc0"
    MODULES="lirc_rpi"
    

Setup IR command to power on/off the TV

  • learn IR command
    irrecord -d /dev/lirc0 ~/lircd.conf
  • copy new file
    sudo cp ~/lircd.conf /etc/lirc/lircd.conf
  • edit the name parameter in /etc/lirc/lircd.conf I choose magicmirror
  • start lirc
    pi@mamomami /etc/lirc $ sudo /etc/init.d/lirc start
    [ ok ] Loading LIRC modules:.
    [ ok ] Starting remote control daemon(s) : LIRC :.
  • check if IR command is available
    pi@mamomami /etc/lirc $ irsend LIST "magicmirror" ""
    irsend: 00000000000043bc KEY_POWER
    
  • run lirc service on start up
    sudo update-rc.d lirc defaults
