Found this, and thought the concept was cool. Consept Switch
But how many lights are practical to fit on a “floorplan” at that scale?
One “switch” per “room” is easy. The concept goes sour when there are several lights per room … plus dimming, etc…
I was thinking since the floor plan is custom, one for each room with multiple lights. Or just two rooms next to each other. That is more practicle than a whole house plan.
