Smart is the new dumb
I know my dishwasher is doing something because I stack it with plates, insert a tablet, physically start it and can hear it working until such time as its done, at which point it beeps.
Making the thing "smart" is just an excuse to charge a hundred quid more for a feature that does fuck all quite frankly.
IoT does have a lot of practical uses, but these "smart" appliances are not one of them. Just an excuse to part fools from some extra money.
