Want to have your home lights turn on and off at a set time or make it look like you're home when you're on vacation? Smart light switches let you do just that. With these switches, you can also control your lights through your smartphone and connect them to other smart home devices, so that your lights will turn on if your security system detects an intruder or your smoke detector senses fire.

After testing numerous models, we think the best smart light switch is the Leviton Decora Smart in-wall switch. It supports three-way switches (so it will work in rooms with more than one light switch); has a robust app; works with Alexa, Google Assistant and Nest; and doesn't require an extra piece of equipment to connect to your Wi-Fi network.

If you have Philips Hue lights and don’t want to replace your wall switches, then the Philips Hue Dimmer is your best bet. Not only is it the least expensive option, but it's also the easiest to install, since you merely attach it to the wall — no wiring necessary. Plus, you can pop it off and use it as a remote control.

Latest News and Updates (May 2019)

  • Lutron's new Aurora Dimmer Switch ($40) looks like an old-school circular dimmer, but this battery-operated devices attaches to the top of a traditional light switch, and allows you to control Philips Hue lights directly. It also locks the regular light switch in the On position, which means that a family member can't accidentally turn off the power to the Hue lights and rendering them inoperable. The Aurora will be available in early June.

1. Leviton Decora

Best overall smart light switch

Rating: 4/5 stars

Size: 4.1 x 2.1 x 1.4 inches | Wi-Fi: Yes | Motion Sensor: No | Works with: Google Assistant, Amazon Alexa, Nest IFTTT | Dimmable: Yes | Supports three-way switches: Yes

Pros: Supports three-way switches; Doesn't require a hub; pretty robust app

Cons: Doesn't support as many smart home systems as Lutron; Lacks geofencing

Leviton's switch won't win any design awards, but we like its no-nonsense approach: a large paddle switch, with a smaller toggle on the right, which lets you dim the lights in increments. A row of LEDs shows you the brightness level, and a small status LED on the bottom lets you locate the switch in the dark.

Unlike Lutron's switch, Leviton's connects directly to your Wi-Fi, so there's no bridge needed. It also supports three-way switches, which is helpful for larger rooms.

The Leviton app is pretty robust. You can set how long the status LED and the dimming LEDs remain on, specify the type of bulbs you're using and adjust the rate at which they dim and brighten. The app also lets you create schedules for the lights to turn on and off, such as at sunset or sunrise.

The Leviton Decora works with Amazon Alexa, Google Assistant and IFTTT, but it supports fewer smart home systems than Lutron does. The Leviton also lacks the geofencing feature found in Lutron's app.

Overall, though, Leviton’s Decora is the best bet for homeowners looking for a great all-around smart wall switch.

2. Lutron Caseta

Most-connected smart light switch

Rating: 4/5 stars

Size: 4.6 x 3 x 1.5 inches | Wi-Fi: Via Lutron Bridge | Motion Sensor: No | Works with: Apple HomeKit, Google Assistant, Amazon Alexa, Nest, SmartThings | Dimmable: Yes | Supports three-way switches: Yes

Pros: Wide range of useful features; Exceptional customer service; Supports three-way switches

Cons: Requires a hub (Smart Bridge); Pricey

The Caséta line of switches from Lutron offers an impressive list of features: geofencing, which means your lights will automatically turn on or off when you leave or arrive at home; the ability to schedule your lights to turn on or off at particular times or days; dimming capabilities; and compatibility with a long list of smart home platforms. You can also control the system using your voice through Amazon Alexa and Google Home, among many others.

Lutron's smart starter kit comes with one in-wall switch, one wireless remote and one smart bridge (hub), which can also be used to connect other Lutron products to the cloud (such as its smart plugs and smart shades) and control them.

The switch itself looks high-tech, with several buttons laid out to control the numerous options Caséta offers. Lutron has gone for function over fashion for the most part with this dimmer: The white and gray buttons are front and center, not hidden by touch-sensitive controls, as is the case with other dimmers in this category.

The only downside is that the switch, like all of Lutron's products, must be linked to the Smart Bridge (you can get it packaged with the switch for $90). The bridge itself must be plugged into your router so that you can control it from your smartphone.

3. Philips Hue Dimmer

Best for Philips Hue lights

Rating: 3.5/5 stars

Size: 4.5 x 2.5 x 0.55 inches | Wi-Fi: Via Philips Hue Bridge | Motion Sensor: No | Works with: Amazon Alexa, Apple HomeKit, Google Assistant, Philips Hue | Dimmable: Yes | Supports three-way switches: n/a

Pros: No electrical installation needed; Voice control using Siri, Amazon Alexa and Google Home; Creative and colorful themes

Cons: Works only with Philips Hue lights; Requires Philips Hue Bridge

For those who have outfitted their homes with Philips Hue bulbs or don’t want to replace their wall switches, the Philips Hue dimmer is a handy little device. It can be used as a wireless remote or as a wall switch, but this switch doesn't need any installation, apart from peeling the covering off the adhesive on its back.

This switch works with only Hue bulbs, though it's almost magic when it does. Just turn on the light containing the Hue bulb as you normally would (even if it's via a traditional wall switch); then, start using the Philips dimmer, and it will automatically work. And don't worry — there's no interference or conflict between the Hue Dimmer and your normal wall switch. The magic in the dimmer lies in the Philips Hue bridge, which is required ($59) for the dimmer to work (and is required for any Philips Hue system).

The Philips Hue app is full of fun controls and creative themes for your Hue bulbs. You can set schedules for your Hue bulbs, which can be controlled by your voice through Amazon Alexa, Google Home and Apple HomeKit. It's also compatible with a host of other smart home platforms.

4. Brilliant

High-tech touch screen

Rating: 3.5/5 stars

Size: 5.6 x 3.3 x 1.7 inches | Wi-Fi: Yes | Motion Sensor: Yes | Works with: Amazon Alexa, Google Assistant, Ring, Sonos, Philips Hue, Ecobee, Honeywell Lyric | Dimmable: Yes | Supports three-way switches: Yes

Pros: Beautiful interface; No subscription required; Alexa built in

Cons: Limited interoperability; Expensive

Brilliant's touch-screen panel lets you control not only your lights, but also other smart home devices, such as cameras, speakers and more. In addition, the panel has built-in motion sensors, so it can turn lights on and off as you enter and leave a room; a small camera lets you use multiple Brilliant panels as video intercoms, and it has Alexa. However, the company needs to add more smart home partners before it can truly justify its high price.

5. Ecobee Switch+

Alexa built in

Rating: 3.5/5 stars

Size: 4.7 x 2.9 x 2 inches | Wi-Fi: Yes | Motion Sensor: Yes | Works with: Amazon Alexa, Apple HomeKit | Dimmable: No | Supports three-way switches: No

Pros: Alexa built in; Turns lights on and off automatically; Motion and temperature sensors; Integrated night light

Cons: Expensive; Can't set schedules for features; no dimmer

Ecobee's Switch+ is more expensive than some other smart switches, but it has a ton of next-gen features. For starters, a motion detector can automatically turn the lights on and off in a room as your enter or leave. A small night light can be activated to help you find your way in the dark. It also has Alexa built right in (along with a microphone and speaker), so you can more easily use Amazon's assistant. The Switch+ also has a temperature sensor, which you will be able to link to the Ecobee thermostat to better control the climate in your house. One caveat: You can't use the Ecobee Switch+ in a three-way setup, and it requires a neutral wire.

6. WeMo Dimmer

Simple dimmer switch

Rating: 3/5 stars

Size: 5 x 3.3 x 1.7 inches | Wi-Fi: Yes | Motion Sensor: No | Works with: Amazon Alexa, Apple HomeKit, Google Assistant, Nest, IFTTT | Dimmable: Yes | Supports three-way switches: No

Pros: Excellent design, high-quality construction; Lighting modes for different situations

Cons: Too many color-coded status lights to remember; Does not support more than one switch per light; Expensive

The WeMo Dimmer looks cool, with its glowing LED status lights, but remembering what each light means (there are seven different statuses, each with its own special LED color) is virtually impossible. One standout feature of the switch is that it calibrates to work with any kind of light bulb for maximum dimming and minimum flickering.

WeMo has included a number of small but nice touches that put the switch at the forefront of this genre of switch. For example, just run your finger along the gutter in the middle of the switch and you can dim or brighten the light the switch is hooked up to. There's also a clever night mode that keeps you from blinding yourself with full-on bright lights when you're headed to the bathroom after hours.

The WeMo app supports numerous smart products and has lots of features, including light scheduling and various lighting modes. You'll also be able to review power-consumption data and to control multiple WeMo devices with a single swipe. It's not compatible with a ton of smart home systems, but the WeMo Dimmer does work with Alexa, Homekit and Google Home, which should be enough for many users.

Smart Wall Switches vs. Smart Lights and Smart Plugs

There are a ton of smart light bulbs on the market that you can control using your phone, so why would you need a smart switch? Smart switches make the most sense when you have a room, or rooms, with many ceiling lights.

Adding a smart switch can be much more cost effective than adding four or more smart lights, each of which can cost as much as a single switch.

If your room is lit by floor or table lamps, then smart plugs are the way to go; you simply connect the lamp into the smart plug and then the plug into the wall outlet. Plugs are generally less expensive than in-wall switches and are easier to set up — there's no wiring involved.

How to Install a Smart Switch

Unlike most smart home devices, which merely require you to plug them into an outlet, installing a smart switch involves replacing a current in-wall switch. Since few, if any, light-control products include professional installation as part of the package, you will need a basic understanding of electrical work, which includes turning off the circuit breaker. For full wireless access, you then replace the entire existing unit with the smart switch by attaching all the wires to the new switch, including the neutral wire.

Smart switches are often bulkier than their traditional counterparts, however; so if they don't fit in the electrical box properly, you may need to get a new box, which is probably a job for an electrician. Similarly, some older homes don't have the right wiring, so an electrician is a good idea here, too. Finally, some smart switches won't work if you have multiple switches controlling a single light (which is called three-way or four-way lighting).

How We Test Smart Light Switches

To test smart switches, we first had them installed (by an electrician) in our house. We then evaluated the switches based on the following criteria:

  • Design: Is it an attractive switch? The best will come in multiple colors to best match your decor.
  • Functionality: Does it support three-way or four-way connections?
  • App: How easy was it to use the app that works with the switch? What sort of features do you get, such as scheduling when lights turn on and off?
  • Smart Home Compatibility: Does the switch work with other smart home devices? How many?

    Good title but content could use some improvement. where is TP-Link, where is wemo light switch, Elgato Eve etc?
  • rocky.seelbach
    Great article. I'd like to add a bunch of smart switches during a remodel, but don't understand why the legacy form factor (toggle) is all but missing from product offerings today. Insteon makes one that's been very reliable for me. The 2466SW is a three position (momentary up and down from center for on and off), but it only works with Insteon. Haven't seen anything similar for Alexa, Siri, or Google.

    Why do none of these have motion sensors?

    Seems obvious. Clicking buttons on the wall seems so 1980s. Google home / Alexa voice controls + motion sensors = I should rarely have to go touch the wall like a cave man. :P
  • nikola99
    IDevices definitely has a dimmer switch and a remote...
  • rapomeroy
    Found there is another consideration - Whether switch can be installed in a 2-, 3- or 4-gang box. I was going to replace only the Right-side switch with WiFi one in a 2-gang box, but cover plate (this was a KMC dual) not compatible with leaving a standard toggle on the left position, I would've had to change BOTH to WiFi.
  • dubinskd
    what about Meross brand?
  • jrmckins
    PHILIPS HUE DIMMER is "best value"?? You can ONLY use it with Hue products. Sorts of defeats the purpose of a smart light switch.

    I am checking out the Meross though (Thanks @dubinskd)
  • cologneled

  • smhmgo
    No word about Gosund brand here. Smart Light Switch of this brand is affordable, design is beautiful and the customer support is simply awesome.
  • cologneled
    Awesome Article!

    Are there any options yet to eliminate wall switches entirely? It seems like a tiny inline component wired at the fixture could be easily done by now. Saving all that extra wire, boxes, and components would seem to offset much of the cost. I suspect that offset would go a long way toward countering people's need for the security blanket of a manual switch they can touch.
