Raspberry Pi Turn Tv On/Off CEC

When building a dashboard using a Raspberry Pi, I wanted a way to schedule the tv to turn on/off automatically. Below are the steps using Consumer Electronics Control (CEC).

  1. sudo apt-get install cec-utils

Once everything is installed you should be able to control the tv using the command below:

Turn tv on: echo on 0 | cec-client -s -d 1
 Turn tv off: echo standby 0 | cec-client -s -d 1
 Tv status: echo pow 0 | cec-client -s -d 1

Troubleshooting Tips:

  • Make sure you tv supports cec and that it is enabled. Tv manufactures call CEC by different names so you may have to do some research depending on your brand.
  • Make sure oyu are using a new hdmi cable that is atleast HDMI 1.2a

Different names for HDMI CEC

  • Samsung — Anynet+
  • Sony — BRAVIA Link or BRAVIA Sync
  • Sharp — Aquos Link
  • Hitachi — HDMI-CEC
  • AOC — E-link
  • Pioneer — Kuro Link
  • Toshiba — Regza Link or CE-Link
  • Onkyo — RIHD (Remote Interactive over HDMI)
  • LG — SimpLink
  • Panasonic — VIERA Link or HDAVI Control or EZ-Sync
  • Philips — EasyLink
  • Mitsubishi — NetCommand for HDMI
  • Runco International — RuncoLink
