One of the most satisfying smart home devices to see in action are smart lights. The thrill of dimming bulbs and changing colors with an app or voice commands has yet to wear off, and it’s one of the easiest products to set up, schedule, and troubleshoot. But what if you want to add smart capabilities to an existing light fixture? If you’re dealing with a ceiling fan, sconce, or some other pre-wired bulbs, you’ll just need to invest in a smart light switch.

These web-connected products come in multiple gang box sizes, and are sold by many different companies. Not all switches are created equal though, and we wanted to round up the best options for those with Alexa, Google Home, and HomeKit ecosystems. So we’ve done just that!

Philips Hue has tied up the smart light bulb market pretty well by offering some great quality lights. While investing in Philips Hue is rarely the cheapest option, it’s certainly one of the easiest. That’s reflected by the Philips Hue Smart Wireless Dimmer Switch V2 which is perhaps the easiest way to add a dimmer switch to your home. It works wirelessly via battery power so there’s no need to worry about wiring or anything complex.

The Philips Hue Smart Wireless Dimmer Switch V2 doesn’t even need a Philips Hue bridge to work although it’s likely you’ll already own one. All you need to do is mount or stick the dimmer switch wall plate anywhere in your home and take a few moments to pair it. From there, you can toggle through four different light scenes by pressing a button on the switch or you can use the dimmer or regular light switch.

It also works as a remote because it’s magnetic and easily removed, so that can prove pretty useful as well. Simplicity is everything here although bear in mind that the Philips Hue Smart Wireless Dimmer Switch V2 does need you to be using Philips Hue bulbs in your home which can be restrictive in some cases.

Frequently Asked Questions

How did we choose these smart light switches?

Sure, you can just pick up any smart light switch and you could be very happy with it, but it makes sense to do some research beforehand. After all, you’ve probably already intensely researched the best smart lamp for your home or similar, so why not keep going? Here are some key factors we considered when compiling this list of the best smart light switches.

  • Accurate pricing: It’s an obvious one for pretty much all purchases but it’s important to think about how much you want and can spend on a light switch. While pretty much no smart light switches are prohibitively expensive, no one wants to spend more than they need to. Some smart light switches don’t offer any unique features but carry hefty price tags because of their branding. We took this into consideration and only highlighted reliable, powerful products that are accurately priced.
  • Compatibility and ease of use: Some smart light switches work with pretty much all smart light bulbs but that isn’t the case across the board. For instance, Phillips Hue light switches will only work with Philips Hue light bulbs, so make sure you buy something that’s compatible with your light bulb setup. We also looked for compatibility with smart home platforms like Apple HomeKit, Google Home, and Matter for the best compatibility.
  • Stylish:Whichever smart light switch you buy, it’s going to be placed on a wall in your home. You want it to suit the aesthetic of your living space so make sure you consider the style before you buy it. Some switches are more stylish than others but it all depends on your personal taste. It could be worth spending a little more if you really want everything to match up and look good.

Nest Smart Thermostat on wall.

Smart thermostats are helpful in reducing your home's energy use, and keeping things comfortable all the time. By factoring in local whether, presence of inhabitants, and electrical rates, you'll barely need to touch the thermostat once it's set up. On the occasion you do need to make some tweaks, hands-free assistants are often tied in. For those with a few Echo devices in the house, you'll want a smart thermostat that plays nice with Alexa. Let's dig into the best smart thermostats that work with Alexa.
Ecobee SmartThermostat with Voice Control

Ecobee remains one of our top picks for smart thermostats across the board. What makes Ecobee particularly Alexa-friendly is a model which has a built-in speaker and microphone. This feature allows users to talk directly to the thermostat as if it were just another Echo device. Ecobee makes a particularly strong name for itself thanks to remote sensors for multiple rooms. This helps your smart thermostat develop a more robust model for your home's climate. The sensors also expand presence awareness, so important rooms stay at a comfortable temperature, while power isn't wasted on rooms with less traffic.
