They don’t do that, but they do send you a push when the fridge door is left open. Which has literally saved my bacon many times.

But that doesn’t need a screen. Why you’d want a screen on your fridge, I don’t understand. It’ll clearly be slow and obsolete long before the rest of the fridge is.

It’s the same thing in car infotainment systems. They’re the first thing to feel dated, and they are increasingly difficult to replace. But at least they give a ton of value from the screen.
