Just ask Alexa to turn on the lights!

You can also control it using your smartphone and the free Kasa app. The app is available on iOS and Android. Again, since your eyes are already locked onto your phone 24/7, it just makes sense.

Use this smart switch to turn electronics and lights on or off from anywhere in the world. You can also use Away Mode to turn devices on and off at different times, to give the appearance that someone is home. Add this switch to a group with other smart devices and control them all at one time.

Installing this switch does require a neutral wire, and it only works in a single-pole setup. However, it does not require advanced electrical knowledge or switch configurations. The Kasa app can actually guide you through the process in a step-by-step installation. You can use the installation guide or videos, too. All you need setup beforehand is a secure 2.4GHz Wi-Fi network.
