Tired of fumbling for the light switch? A smart light switch provides hands-free voice control using modern conveniences like smart speakers and assistants to turn your aging house into a futuristic home of tomorrow. Not only can you can use smart switches for lighting (alongside smart dimmers), but most are also compatible with bathroom fans, ceiling fans, humidifiers, garbage disposals, and even electric fireplaces.
After weeks of testing, we’re confident the best smart light switch you can buy is the Lutron Caséta Smart Switch(available at Amazon for $59.95). Though it requires a hub, it offers plenty of versatility like support for single-pole or three-way light switches (when paired with Lutron's Pico Remote), compatibility with all three major smart assistants, and convenient smart features like geofencing. The Geeni TAP Smart Light Switch (available at Amazon) is also a great, value-packed single-pole option for those on a budget.
Here are the best smart light switches we tested ranked, in order:
Lutron Smart Switch
Geeni TAP Smart Light Switch
Gosund Smart Light Switch
Wemo Wi-Fi Smart Light Switch (second-gen)
Meross Smart Light Switch
Eve Energy Smart Light Switch
TP-Link Kasa HS200 Smart Wi-Fi Light Switch
Leviton Decora Smart Wi-Fi (second-gen)

Lutron is one of the leading names in smart home lighting and this smart light switch is the best it gets. Its dependence on a hub is something we usually frown upon due to the additional cost, but Lutron’s lighting system is worth paying more. Here’s why: It was the easiest to install and set up. It’s wired for single-pole, but can be turned into a three-way switch when paired with Lutron’s Pico remote. It’s also quick and responsive to voice commands via Alexa, Google Assistant, and Siri.
In addition to lights, the 120-volt switch can be used for ceiling and exhaust fans, and unlike some switches, it works with LED, incandescent, and halogen bulbs. The Lutron app is full of convenient smart home features like geofencing to turn the lights on when you get home (a rarity for smart switches), scheduling, and scenes, which all work well. Another reason to buy this switch is that it supports a plethora of popular smart home systems like Sonos, Samsung SmartThings, Ring, and IFTTT. You can even manage your entire Lutron Caséta lighting system from an Apple Watch. Lutron also has a full suite of smart home gadgets like smart dimmers and outdoor smart plugs to help you build out a more connected home.
The light switch requires a neutral wire, but if your home doesn't have one, check out the Lutron Caséta Smart Dimmer, which also works as an on/off switch but does not require a neutral wire. (The light switch can handle a larger electrical load than the dimmer, so we’d only recommend pairing the dimmer with lights and not exhaust/ceiling fans or other outlets that may draw too much power.)
Despite all of its great qualities, the Lutron app lacks two-factor authentication, a privacy feature that helps keep your account secure (though it’s something a lot of switches don’t support). As mentioned above, the switch needs a Lutron Pico remote control or a Lutron Caséta Smart Bridge to operate, which is an additional cost to mull over. But this system is really smooth and, unlike other switches, integrates with many different smart home platforms, making the extra cash worth spending if you’re whole-home smart lighting is what you’re after.
If you only need a switch or two, we recommend the value-packed Geeni TAP Smart Light Switch. It supports hands-free voice control with smart assistants like Amazon Alexa, Google Assistant, and Microsoft Cortana. This single-pole switch is easy to install and maintains a reliable connection. Additionally, Geeni’s companion app is one of the only ones we tested that offers two-factor authentication, an important privacy feature that helps keep your smart home secure.
Within the app are useful features like scheduling, remote control, and the ability to group the switch with other Geeni products for easy home automation. We had no issues installing the switch, which is designed to handle 120 volts, thanks to the clearly marked wires on the load box. As is the case with most smart switches, a 2.4 GHz internet connection is required for use. It does not work as a three-way switch, though Geeni does make one. It is designed to control a single light only and a neutral wire is required.
Now for the downsides: Geeni’s switch has a budget look and feel to it, but that’s part of the trade-off for a low-priced switch. It also lacks compatibility with Siri, so we don’t recommend it for Apple smart homes. But if you need a dependable smart light switch that offers remote control, good security features, and integration with Alexa and Google Assistant, the Geeni TAP switch offers great bang for your buck.
Each switch was installed and tested inside of a 1,400-square foot home and connected to an Eero Mesh Wi-Fi router. The home we tested in was built in 1955 but rewired with all new electrical in 2017 (including neutral wires). We evaluated each switch’s setup process, app (including security features like two-factor authentication), physical and digital performance, smart home ecosystem integrations, remote control capabilities, and integration with popular virtual assistants, including Siri, Amazon Alexa, and Google Assistant.
Replacing every light in your home with smart light bulbs can get expensive quickly (especially if you have lots of multi-bulb fixtures). That's one of the best things about buying smart dimmers and switches—you can convert an entire chandelier's-worth of "dumb" bulbs to smart ones with one switch.
Depending on the smart switch you choose, the initial cost of installation may be slightly higher than the cheapest smart bulbs, but your dimmer switch is far less likely to need to be replaced, which will save you money over time. Plus you will never run into the frustrating scenario where you are yelling at Alexa to turn on the light, but somebody turned the regular light switch off without thinking, and therefore your smart bulbs are off-line. Not that we have ever experienced anything like that.
Smart bulbs are a more attractive starting point for those who want to ease their way into smart home lighting slowly, one bulb at a time, and the more expensive smart bulbs are also loaded with lots of options when it comes to color lighting and scenes. A smart dimmer won't offer you the same bells and whistles as a multi-color smart light bulb, but it's generally less fussy—and that's worth a lot.
Tips to Know Before Buying a Smart Light Switch
Before you buy, take stock of what switches in your home you’d like to replace. Most smart switches are broken up into either single-pole or three-way switches. A single-pole switch controls one light. A three-way switch also controls a single light, but from two different locations (like at the top and bottom of a staircase) instead of just one. Some combine single-pole and three-way wiring into one switch, though it’s more common than not that it supports one or the other.
Most of the smart switches in our guide offer remote control via companion apps on both iOS and Android, but make sure to check that your device is compatible before you buy. Most switches support automation features like timers and daily schedules, but only a few offer convenient features like geofencing, which uses your location to automatically power the lights on/off as you come and go, and Away Mode, which randomly turns the lights on/off when you’re away from home for an extended period of time.
As is the case with many smart home devices, a 2.4 GHz internet connection is required to set up and use most smart light switches.
Privacy and Smart Switches
There’s always a potential privacy risk involved when you use internet-connected devices at home. To help safeguard your smart home, there are some steps you can take. First, look for devices that offer two-factor authentication, which sends a code to your mobile device to verify it’s really you. That way, if someone tries to hack into your account, you will receive an alert and can quickly take care of the problem. Many devices also allow you to activate email or other push notifications in the settings to alert you if someone has logged on.
Additionally, make sure to use a unique, strong password composed of multiple characters, numbers, and letters for each of your smart home accounts. Data breaches feel like the norm as of late, making it all the more important to use different passwords across multiple websites and apps.
Gosund’s Smart Light Switch works well for remote management and hands-free voice control via smart assistants Amazon Alexa and Google Assistant (but no support for Siri). It’s a simple, budget smart switch that can be installed in just a few minutes.
The app is polished and works well on both iOS and Android. In the Gosund app, you can access scheduling features like timers and a countdown, which shuts off the lights after a certain amount of time. The app doesn't offer two-factor authentication, but verification codes are sent during account creation and if you reset your password.
On the downside, the switch’s materials feel cheap. For example, the included wall plate feels exceptionally flimsy like it could break while removing it, so be gentle during installation. The aesthetics could be better, too. The Gosund logo takes up a sizable portion on the bottom of each switch plate and looks gaudy. We’d recommend using your own switch plate for more of a low-key look and feel.
In short, there’s nothing wrong with this light switch, but nothing remarkable about it either.
Wemo’s second-gen smart light switch has one of the slimmest, most modern profiles of the light switches in our guide. It is responsive and works well for remote control, as well as voice control via Alexa, Google Assistant, and Siri, which can all be used in tandem.
The Wemo app offers useful automation features like scheduling, an auto-off timer, and remote control. However, if you’re using HomeKit, make sure to create Rules in the Apple Home app and not in the Wemo app to avoid potential conflicts and ensure your automations go off as intended. One bummer with the app is that it does not offer two-factor authentication so you won’t be alerted about unwanted login attempts.
This switch supports one-way connections only and is not compatible with 3-way switches. A neutral wire is required. The Wemo app offers useful automation features like scheduling, an auto-off timer, and remote control. Away Mode, a feature that randomly turns lights on and off to give the appearance you're home when you're not, is also available in the Wemo app.
One thing to note is that, if you’re hooking the switch up with HomeKit, make sure to create Rules in the Apple Home app and not in the Wemo app to avoid potential conflicts and ensure your automations go off as intended. An Apple Home Hub like the HomePod Mini is needed to control the plug using Siri when you're away from home.
The Meross Smart Switch is easy to install and comes with labels so you can mark your wires during setup (an especially helpful extra if you’re new to understanding your home’s wiring). This is a single-pole light switch that requires a neutral wire. Overall, we found it to be responsive to voice commands and via remote control in the Meross app.
It works with Alexa, Google Assistant, and Siri. However, you can’t use all three smart assistants in tandem like you can with other switches that support the big 3. It also works with Samsung SmartThings. An Apple Home Hub like the HomePod Mini is needed to control the plug using Siri when you're away from home.
One annoying feature about the app is that it asks to confirm if you want to turn the light on/off when you press the power button. This was automatically turned on for us during setup, but can be turned off in the app’s settings. Like a lot of switches, Meross’s companion app also lacks two-factor authentication, a security feature that alerts you to attempted account logins. It also doesn’t feel as luxurious as our No. 1 pick and when you physically press the switch, it makes a pretty loud “click” sound.
If you need a smart switch that exclusively works with Apple HomeKit, the Eve Light Switch is a savvy pick. Though it doesn't support Amazon Alexa or Google Assistant, Siri can handle turning this switch on and off for you without delays. Aside from great performance, the switch is also one of the most aesthetically pleasing to look at, and the touch on/off is really slick to use.
In addition to Siri, you can also use an Apple Watch to control Eve's smart wall switches. An Apple Home Hub like the HomePod Mini is needed to control the plug using Siri when you're away from home. The switch requires a neutral wire and does not work with three-way switches.
As far as app security goes, Apple HomeKit requires your iCloud Keychain to be active. Since an Apple ID is required for HomeKit and Eve, two-factor authentication is available to help keep your Eve switches secure. The switch can be managed from the Home app, but you'll need the Eve app to set schedules, install firmware updates, and adjust the LED status light. Overall, this is a solid option if you need a smart switch that works with HomeKit, but steer clear if you prefer to use Android or smart assistants like Amazon Alexa, Google Assistant.
From indoor security cameras and smart plugs to smart light switches, Kasa is no stranger to reliable smart home devices. We’ve been living with TP-Link Kasa’s Smart Light Switches for more than a year and can confirm they are responsive in both the Kasa app and via voice control with Amazon Alexa and Google Assistant. One fairly unique feature of this switch is that you can also check out the current and total runtimes, broken down by day, week, and month in the Kasa app.
There are a few downsides to this switch, though. The switch sometimes randomly goes offline (but manages to reconnect itself), and the Kasa app does not offer two-factor authentication for increased account security. The switch also doesn’t work with Apple HomeKit, so if Siri is your smart assistant of choice, check out other options in our guide.
Like other switches, Kasa’s works for single-pole switches and needs a neutral wire. The app, available for both iOS and Android, supports features like remote control, timers, scheduling, and away mode.
The new generation Decora from Leviton streamlines everything into a single switch for hands-free voice control with Amazon Alexa, Google Assistant, and Siri. The switch is compatible with single-pole or three-way installations and requires a neutral wire. However, for an additional cost, you can add the wire-free DAWSC Anywhere Switch Companion. The companion switch is a really nice supplement for areas of the home that lack proper wiring, like a hallway or base of a staircase.
The switch is slightly smaller than other smart switches, which is nice if you have a crowded in-wall electrical box. The installation itself was quick and easy, and we had no issues integrating it with all three smart assistants. However, after a successful setup, the switch randomly lost connection and needed to be reconnected several times during our testing. Additionally, the Leviton app does not offer two-factor authentication to help secure your account.
We liked Leviton’s second-gen switch when it worked (and the ability to add the Anywhere Switch is a nice bonus), but it didn’t maintain a reliable connection during our tests, which is crucial to managing your smart home remotely or via voice assistants.
