The light switch stuff has actually worked out well for me with a specific case. Living in apartments with basically no interior lighting at all. There'll lights in the kitchen and that's about it. You're expected to use lamps and there might be one or two switched outlets. The smart home stuff combined with some battery operated controllers that i can double sided tape to the wall I can add my own switched lamps that have wall switches without tearing the walls out to run my own wiring. Makes things much closer to a normal place. Other than that it didn't tend to get used nearly as much but it was fun being able to turn off the lights on someone from work.
