I have compiled and built LibCEC library on Raspberry Pi and I got an working cec-client utility. I would like to use it for more than just turning on/off the television, and this article has the purpose to gather standard and non standard commands to control one or many CEC devices.

1) Scan devices with the following comand:

echo scan | cec-client -s -d 1

 

2) List known shortcuts by a cec-client utility:

echo h | cec-client -s -d 1

 

3) If the television and the device id 0 you can turn it on using the following command:

echo "on 0" | cec-client -s -d 1

 

4) Turn off the television with id 0 using this command:

echo "standby 0" | cec-client -s -d 1

 

5) Swicth to the channel where the cec-client runs:

echo "as" | cec-client -s -d -1

 

6) List client and device details

cec-client -l
