Room Color Temperature

Hello, I’m noob with floorplan, and fiddle with home assistant for a few months.

I want the room background color to change with temperature (solid or gradient).
I tried to modify examples, read documentation multiple times… I know a few things in python, but I’m stuck

Found my mistakes :

  • use text_template was useless in that case (don’t ask why I let that in…)
  • was using “temp-in-low” instead of “temp-very-low-background”

Have still much to learn though ^_^"
