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

  1. Thank you for this post !
    After searching and trying hours and hours it helps me.
    But…
    On my Pi B+ with Debian Wheezy 1.4 I only need to install by:
    sudo apt-get install cec-utils
    That’s all
    Sorry… You have error’s in the documentation for switching on and off.
    You must type in:
    echo standby 0 | cec-client -s -d 1
    or
    echo on 0 | cec-client -s -d 1
    without ‘

    1. Thanks glad it helped you! Most likely it’s because I was using an older os version. Hopefully this comment will help someone else. I’ll update the post.

    1. From the libCEC Vendor Compatibility Site:
      Concerning “Samsung” and “Power Off”
      “Some models require you to turn on “Auto-Standby” in the Anynet+ settings to enable this feature”

      1. “Some models require you to turn on “Auto-Standby” in the Anynet+ settings to enable this feature”

        That did the trick for me, thanks!

  2. Hi there,

    thank you for the tutorial provided. I am able to turn on and off my Panasonic E-30. However it takes some seconds to execute. Turning on debug out I can see many timeouts:

    Everything works but still the long delay is kind of disturbing. Any idea what could be the problem?

    Cheers,

  3. Thanks for the post!

    I’ve got my pi successfully turning the TV on (Kogan TV) however the standby command isn’t working. I’ve got auto-standby and auto power on set to on in the cec menu. Anything else I should try?
