Vero 4K and home theater system integration

Hi, again
While I’m waiting for the program update with standby mode implemented, i decided to try screensaver to turn off TV and AVR as described in this topic: “[HowTo] Power off display by screensaver and remote control”

I enabled screensaver “OSMC Display Power”. And now i can turn OFF TV and AVR by pressing key on remote. OK.
But that’s what happened: screensaver settings have wait time and you can change it from 1 min to 60 min. If I do not turn off the Home theater system with screensaver by pressing dedicated key on remote and switch to another input on TV to watch cable TV, the screensaver on Vero 4K after some time (1-60 min) shutdown all system.
How to fix this problem, so that the screensaver can be activated only with remote control, but not after some fixed period of time (1-60 min)
