Alright time for an update. Thanks to @Erikje how has done some initial testing I have done a lot of updates on it.
So what have i done:
- Have made positioning much better between settings and actual
- Have made a rule system for Devices.
- Default: You cant a color switcher that has Yellow for on and White for off
- You can select one color to always be there independent of state
- You can add a image switcher. I have 3d rendered with lamps on and off so i can overlay them and switch
- I have support for onOff and Dim now
- I have listener for states to change icons and images if you have these rules from external events
- Probably a lot of other stuff that I don’t remember

So what is left:
So many different things but we are closing in on something that me and other can use
I do not support portrait layouts for now. they screw the ratio and then positioning. I will not spend time right now try to fix that.
This is how the overlay images work if you wonder:
One with everything on
Then each room transparent with only the room dark
And here are some screen shot from how it looks on mobile right now
And some from settings
And a small video showing the image switcher and how it works
