The attached file is a design approach, it does not exist as a reality. I put it to describe my thought to you which I could not implement because the supported file in dimensions did not fit exactly as I thought of it.
As we can move (at rows and columns) the shortcuts (tiles) of our devices when we design the appearance of our devices in the app web cast imagine that we can insert a custom photo or drawing as a background. If we could insert a large photo like the one I show you which is a floor plan of my house we could easily assign each of our devices to each space like my example.
I have already suggested a similar improvement, as an example I pointed to the map that is available in smartthings. There is much more cool there than what you are suggesting. There are no results yet.
