I looked at the code of MMM-scheduler and that does the job, but remote would be great. I have some experience in coding and I can see that is possible, but my coding was 20 years ago… I could see me creating an ioBroker adaper that would then allow ioBroker to fully control the Mirror. API endpoiints for most of it are there. I managed to get my doorbell working and show the image of the camera on the mirror by ussing ioBroker, stuff like that could be really cool. But the dimming is a problem, as I need to be more flexible with the screen, hence my question. Thanks for further thoughts.

@chrga ok. Should be nothing to stop it Did you try my Module and the examples on the alert module did you add the ViewNotifications module so you could see it being broadcast The structure of the notification is exactly the same as if you were coding it in a running module

@sdetweil ok, that makes sense, caching might be an issue!
