I don’t need the damned refrigerator to have an opinion on what i eat!
And I don’t need the Dish Washer bitching about me not pre cleaning my dishes either!
Three years ago I was fortunate enough to be able to drag a 40 year old dishwasher that had only two years of use on it out of the basement storage to replace a ~45 yr old dw that had finally died. This one has better features including two soap washes from a double soap dispenser dual door arrangement. It only uses hot water and plenty of it. Cycle time is one hour and it uses about one kWh of coal fired electricity. Dishes come out spotless.
So far at least, nothing says you have to connect them to the internet.
My fridge shows up on my network...but its just ignored and not connected.
