SpaceAPI

Example screenshot of HA dashbord created by the code below:

configuration.yaml

xopr is not sure what syntax (legacy or new) is used (frankly, the HA logic and templating system is a mess and he couldn't care less). The result is that it is unclear if sensors could be generated from a for loop, if attributes (like lastchange) could be set, whether something simpeler than wrapping Markdown around some data to show a dynamic image, and so forth.

Update this code if you think you know better. I've searched the forum all evening and mostly found the Gudim meme one way or another; currently this is a "Works for me™" solution..

Example raw dashboard

Do note that there are several versions of the spacestate on this dashboard; I'm still looking to see which one does state history better.
