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
