See that’s utility and depending on the sensors you choose that can definitely be local only
But skimming the page for a Samsung smart fridge none of this is in the features. It’s that it can play music, you can put notes and pictures and shit, there’s an “ai camera” that can tell you what you need to buy (though something tells me that struggles if your fridge isn’t set up like a stock image and is actually loaded with like food and condiments and shit like a normal person)
A Bluetooth speaker can do the music part likely with much better sound quality, a smart speaker can handle the typical kitchen tasks like setting timers (which can be done purely in HA, you don’t need Alexa or whatever), a dry erase board and magnets can cover notes and pictures, and the reminders app on your phone can probably do a much more accurate job of keeping a shopping list. Then you can buy a fridge that doesn’t have a 32” proprietary lcd that is a major point of failure, and you can literally save thousands of dollars (quick search shows these fridges are 3500-4k, which is insane for a fridge, even a fancy huge one).
The market for these is people who have too much money (or are willing to take on credit debt) but also can’t be bothered to spend the 1-2 hours it takes to read up on how to do what you’ve done. Samsung, Apple, Google, Amazon, etc prey on these people
The top of the line one can make spherical ice though, which is admittedly super cool
