Best Smart Light Switches iMore 2019

Installing a smart light switch is a great way to reap the benefits of connected lighting without having to worry about buying individual smart light bulbs in all different sizes. Best of all, having an in-wall smart switch means that you will not have to explain how your smart home works to your guests when all they want to do is turn on and off the lights. The Lutron Caseta Dimmer Switch is the best overall smart switch for its ability to be installed without a neutral wire and it performs with a high level of responsiveness and reliability. We have gathered up all of the best smart light switches to help you decide which one is right for your needs.

Best Overall: Lutron Caseta Dimmer Switch

The Lutron Caseta Dimmer Switch combines robust smart home integration, solid performance, and more with an easy to install package that can have you up and running in no time. Lutron's low power Clear Connect technology enables the ability to function wirelessly without the need of a neutral wire, which many older homes may lack. This proprietary wireless protocol also provides ultra fast response times, and rock solid reliability.

Lutron's Dimmer can be controlled via all of the major smart home platforms, such as Siri, Alexa, and the Google Assistant with just your voice. Of course, you can also use the Caseta Wireless App, or Apple's Home App for those that use HomeKit, to toggle your lights on and off when you are away. Physical dimming buttons are also located on the switch itself, providing a quick and easy way to adjust the light levels in your home.

The Caseta Wireless Dimmer can also be used in more complicated electrical scenarios, such as three-way wiring where two light switches control the same fixture. This type of wiring is a breeze with the Caseta Dimmer, as a coordinating Pico wireless remote can be used to replace the second light switch entirely. Other Caseta accessories include fan speed control switches, and traditional on and off switches to cover pretty much every switch type that you may need.
