You are probably in a room right now? If so maybe I can interest you in yet another idea which could be a good one..
I propose you replace your existing light switch with a home assistant UI mounted in its place with a screen which will better serve you.
Light switches are actually positioned in places are more likely to find useful such as by the front door or on the move in your house.
Also a screen is easy to clean rather then a switch gathering germs.
So maybe the idea is overkill or maybe not?
Should I ask for help to build a prototype, form a team?
