The TP-Link Kasa Smart Dimmer Light Switch usually costs $40, but right now, Amazon has it on sale for $33.03. We've never seen it drop lower than this outside of bundles before. You may also be eligible for an additional 30% off via clipped coupon, but that offer isn't extended to all accounts. Customer testimonials are stellar, too.
You can control your lights directly from this switch or from anywhere in the world using the free Kasa app, set a schedule to control your lights so people don't notice you're away, and make use of the gentle off feature to fade the lights while you fall asleep. These switches also work with Amazon Alexa, Google Assistant, and Microsoft's Cortana for hands-free voice control. They do require a neutral wire and a 2.4 GHz Wi-Fi network.
