We’re still talking about marginal, unnecessary things, but with a “smart” coffee pot, you could in theory start the pot when you’re a few minutes away from home, if you like some after work. A pot connected to something like home assistant (which I have no idea if it exists) can brew the pot only on your workdays, or you can start it after you leave the bedroom, regardless of time. You could probably do quite a few “neat” things.
