Sorry, you are incorrect. I have a house full of Hue devices, for many years now. I also have many houseguests. Not once did I ask any of them (or my wife, for that matter) to use an app to do anything in my home. To turn the light on or off, everyone here either uses Hue switches, or just walk into the space, if it is a common space, where the motion sensors takes care of things.
I ask my guests to open a PR or github discussion if they want the smart door to toilet open. The config is right now hardcoded and it has worked very well to keep guests away from my home to give me focus time.
Whenever I install or (re)configure something involving "Smart Home" I think carefully about what will be returned when family/partner does a `git blame` ...
