I had this very discussion on Twitter a few days ago, wrt "smart" refrigerators. The one thing that would be legitimately useful would be a batter back real time clock and thermometer, to alert you when the power went out, and what to throw away. I'd be shocked if this feature exists on any refrigerator. Not because it's difficult (It's not. Just monitor the temperature and print a stock FDA guidance), but because it's not what a product manager actually thinks of. Instead we get cameras inside, weather, Alexa integration, Google photos, just... bullshit features. Nothing that that anyone really needs.
