Installing a smart light switch is a great way to reap the benefits of connected lighting without buying individual smart light bulbs in many sizes. Best of all, having an in-wall smart switch means you won't have to explain how your smart home works to your guests. With a smart light switch, you can turn lights off and on and dim them with your voice, an app, or a smart speaker from Apple, Google, or Amazon. If you're ready to add some smarts to your home setup, look at this list of top picks.
