Smart plugs are a great addition to your home if you want to save money on your energy bill. Aside from talking to your house and having it respond with actions is just cool. By using the scheduling feature of your smart plug's app, you can schedule things, like your lights, to only come on during certain times of the day when you're home, so they're not wasting energy in the meantime. If you use heat-powered appliances regularly, such as a curling iron or a clothes iron, plugging those into a smart plug allows you to turn them off remotely from your phone, so your smart plug can save the day.
