What do people even do with their wifi appliances?
Timing, automatic and stuff. To keep the washing machine example: you want the laundry out of the machine as soon as possible go hang it up as fresh as possible. You’re having a long day ahead of you, not a long time between coming home and going to bed, not enough for a full laundry run at least. You load up your machine before leaving home and remote start it the adequate time so it’s done shortly after you’re back home.
At least that’s what I’d use such features for.
