When it comes to smart homes, the one item that can really make a difference is the smart plug. Smart plugs are the fastest and most affordable option for ordinary people to turn ordinary household appliances into a smart home ecosystem. For example, you can plug in your coffee maker and have your morning cup prepared a few minutes before you wake up. Or you can use your smart plug to turn on the air conditioner or heater before entering the room to get it to the right temperature. You can even use it to automatically turn on the lights in the driveway, so you don't have to search in the dark when you get home late at night. On a practical note, smart plugs and sockets can also measure your electricity usage, letting you know which appliances are causing your electricity bill to rise. Once you know which appliances use the most electricity, you can actively work to reduce their consumption or replace them with a more efficient model. If you do plan to purchase from Apple's online store, you may want to consider Eve Energy Strip-Connected Triple Outlet ($99.95) or the Eve Energy (Matter) Smart Plug-Two Pack ($69.95) to your cart. However, there are plenty of other Apple HomeKit-compatible outlets at different price points that you can consider as well.
