Hi,
I have fixed problem by workaround.
Using knowhow from article ODroid C4 stop going to sleep - #3 by inversechi
(user Portisch, THX) I have tuned CEC settings to disable Odroid sleep when CEC command switches TV off.
KODI: Kodi->Settings->System->Input->Peripherials->CEC options
changed lines:
- When the TV is switched off → Ignore
- Devices to power off during shutdown → None
You can close this Thread. Problem is fixed by Kodi configuration update. It is not CoreElec bug.
