My wall panel dashboard. Don’t mind the weird mixture of English and French, this is still in development (as a programmer I tend to keep stuff in English and it’s so much shorter than French) 
The blue tiles open popup menus, which automatically close after 30 seconds of inactivity and go back to the main dashboard.
This runs on a cheap 7 inch tablet that I originally intended for wall mount, but it works just as well lying on a cupboard in the hallway. And at least I don’t have to rip open the drywall to run power lines. I adjusted the UI many times, eventually converging onto something that should be user friendly, intuitive and discoverable, even by someone who doesn’t know the system. And it looks at least acceptable aesthetically. Internally it uses a heavily modified version of Tileboard.
