My relatively poor grandparents and my slightly less poor parents had a hard working life, but none of them had to sleep in a dark cold room because the switch to turn the lights on or the heating stopped working. Ever. This problem has been solved by other people many many years ago.
Last month I watched a documentary where a billionaire was showing of his multi million mansion and when he wanted to show the camera team his 100k home cinema room they couldn't see anything because his smart lighting system was stuck in an update loop and nobody had a clue how to fix it. In the interview he said it's not a big deal because he doesn't like to have the lights on when watching a movie anyway. L.O.L.
If I had a 100k cinema room then it would be certainly be a big deal to me if I can't even see where the heck I'm walking.
In my entire life I never thought "damn, how nice would it be if I could turn on the lights in my bedroom from downstairs on my phone". It's just not a problem which I think people have, but somehow the consumer industry has convinced so many fools to buy cheaply fabricated, badly secured, even worse programmed and often not long supported smart home devices which add absolutely no benefit to anyone's everyday life and cause lots of problems.
By the time I find my phone lying around in my lounge, unlock it through Face ID or finger touch, open up the home app, find the home device which I want to control, then make whatever change I wanted to do I am much faster to just get my arse up from the couch, walk over and turn it on/off with a normal hand movement. On the way I can also grab a beer from the fridge and then continue watching the telly and laugh about some fools who spent 100k on a home cinema without lights.
