Never seen the point of "smart" kitchen appliances. Smart lighting, smart meters and smart thermostats, yes, they are handy. I have a smart thermostat and couple of hue bulbs. It *is* sometimes handy to be able to switch them on or off remotely.
Kitchen appliances are different. Nearly every appliance, be it a Fridge, Washing Machine, Dryer, Oven, slow cooker or whatever requires a user to deal with it physically, if just to load or unload it.
I don't see the use of smart appliances in the kitchen. Yes, your oven can look up a recipe for you, but so can a tablet, mobile or laptop. Yes, you can trigger the device to do it's function, be it Washing, Drying, cooking or whatever, but unless the device already has washing or food in it, that is pointless, and when you load up the device, you can trigger it then and there, or set a delayed start, on the the device controls.
Fridges are even more useless. They are running the whole time anyway, so can't be triggered by an app. Yes, they can order food from your supermarket, but that requires a sane system of tracking stuff that is put in and removed from the fridge, and a human still needs to check the fridge for spoiled contents anyway. Yes, you can surf the web from your fridge. This would be a selling point in the 90s or early 00s, but you can surf the web on pretty much anything now, and most people have a mobile that can do it.
In the mean time, some things all these smart devices *do* achieve is to increase the amount of potential vulnerabilities in the security of your home network, and they also no doubt report what you do to the manufacturer and whoever they chose to store their data. One potentially handy thing is that assuming they detect a fault, they *can* call the engineer. Theoretically that is a good thing, but in practice it depends on the calibre of engineers the manufacturers employ, as it will only call them.
