Kodi->Receiver->TV - want to turn on TV-monitor through HA

It’s not the same context as your issue, but this could be useful:

Specifically creating a hass switch, and getting the switch to send the CEC commands, e.g:

  platform: command_line
  switches:
    tv_kodi:
      command_on: ssh root@[Kodi IP] "echo 'on 0' | cec-client -s"
      command_off: ssh root@[Kodi IP] "echo 'standby 0' | cec-client -s"
      friendly_name: TV
