Dumb appliances can be combined with smart plugs to create inexpensive smart appliances. This dumb coffee maker can be controlled with both Siri and Alexa. Complex schedules can easily be configured with smart phone apps, such as only weekdays, instead of clumsy buttons on digital coffee makers. On the weekends, when I wake up at inexact times, I just tell Alexa or Siri to turn on the coffee maker and my coffee is ready by the time I go to the kitchen.
Smart plugs only work with dumb appliances, that is the appliance must have a physical switch that is always in the on position regardless of whether the appliance is unplugged and plugged back in. A digital coffee maker would not work because the power button would not be pressed if it was unplugged and plugged back in.
This video shows how Siri or Alexa can turn on the coffee maker instantly, hands-free and eyes-free.
