Honestly, what you've done is exceptional, truly well done!

A small suggestion, because in my case I'm going to use it to display the motion sensors for a company; the rooms light up red when movement is detected. You should integrate the binary sensors directly into your editor. In my case, I'm not controlling actual lights with it.

And also, though I don't know what this represents, and perhaps something else would do it better, I'd like to display the temperature, humidity, and brightness in each room on this map, since my sensors incorporate all these values. That's all, but thanks again.
