Feature Request: ADD CEC Control... #1178

Add CEC Control over HDMI

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 your 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 you are using a new hdmi cable that is at least HDMI 1.2a
