Hi @petro
I was wondering if its possible in lovelace to make the floorplan look bright or dark according to day or night.
The state of each light in each room can then be integrated regardless of day or night.
You probably could by setting the style on each of the elements. Not sure if it could be done based on state. Might require a custom version of the card.
thats a little confusing for a noob like me but I will have a go. thanks for your recommendation buddy.
