Stupid question I could not answer myself

[Innominatapersona]

My apologies for what I think must be the most stupid question on github.
Once I installed and configured the addon and registered my phone companion app among browsers, my phone's screen won't suspend anymore. I know I can switch on and off the screen using the light entity, but I'd simply like to let the phone manage the screen, showing a stock clock dreamview screensaver as it should. Of course I disabled the always on screen option. I tried disabling light entity and removing permissions to companion app, but he screen always remains on.
Can this be done without removing browser mod in the first place? Does anybody know how?
Thanks for help
