My fridge, washer/dryer and stove are all smart units. I'm not.
I have no idea what they do in smart mode, so I made them as dumb as I am. I had a tech disable the feature on all of them when they were installed.
The only feature I saw was useful was on the stove. I could remotely turn it on or be advised by an alert that the probe says the tofuturkey is done. Big whoop.
I just see these as a another back door to the access of my internet.
