I have a smart LG that, as of today, has had its internet privileges revoked because it installed yet another update that changed how our shit works. 100% of our TV viewing is done through an Apple TV, but I kept the LG online for the odd occasion that I wanted to cast my phone to it to show my wife something.
But nope. No more will our LG talk to the internet. It's lost the right.
A huge swathe of smart devices literally just need some way to turn them on or off without needing to be right next to them. A kettle, for example, that could be activated a minute or two after my alarm goes off so it finishes boiling as I step into the kitchen would be quite nice (though not terribly necessary). Equally, an oven or air fryer that could be turned on remotely to pre-heat might be nice.
But honestly, I don't have a single smart appliance in my kitchen, and I can't say I'm the poorer for it.
