Change power off key in Raspberry Pi

Hello,

I have installed Libreelec in my Raspberry Pi. It works great playing videos and music.

As Raspberry has not suspend mode, I want to switch off the TV (CEC) with remote power off key. And then power on the TV (CEC) pushing again the remote power key.

Is this possible?

Best regards.

Hello, I am using a Sapphire remote with a USB receiver. It works great all buttons, but I want to change the power key to not shutdiwn the pi and to power on/off the TV with CEC.

Regards.
