Smart lighting is one of the major reasons for initially launching a smart home ecosystem. Controllable with top voice assistants like Alexa, Google Assistant, and HomeKit, smart lights can be powered on/off remotely, automated, and more, all with simple voice commands and companion app controls. If you’ve been wanting to integrate your lighting into your smart network but can’t stand the thought of retrofitting all the bulbs, a smart light switch is a great alternative.
Offering a number of the same perks as today’s leading smart bulbs, smart light switches are easy to install and simple to manage, whether at home or on the go. For your consideration, here’s a roundup of the best smart light switches available right now.

Lutron Caseta wireless dimmer
As far as smart lighting systems go, this switch by Lutron is one of the easiest to install and most feature-heavy on the market. This smart light switch doesn’t require a neutral wire. Plus, it offers geofencing capabilities, which means your lights can automatically turn on when you arrive home and turn off when you leave. You also can schedule them to turn on or off by themselves at certain times of the day, a great feature that can make it seem like you’re at home when you’re actually away.
The switch itself is highly functional, with different buttons indicating exactly what your options are, whether you want to turn out the lights or adjust the brightness. Want to use voice commands to control the lights? Integrate the Lutron switch with Amazon Alexa, Google Assistant, or Siri to get started.
Keep in mind that you’ll need to get the Lutron Smart Bridge to use all the features with any Lutron products, including the Caseta. You can purchase a starter kit, which includes the bridge and a remote control. The bridge must be plugged into your home’s router for you to control the lights from your electronic device, such as a smartphone.
WeMo Wi-Fi Smart Dimmer
Looking for a light switch that doesn’t require you to buy a whole new set of bulbs for the house? This one by WeMo will calibrate itself to any type of light bulb by way of the WeMo app. The switch also has some interesting design touches that place it ahead of the competition. For example, you can use a finger to control the brightness by running it along the gutter in the center of the switch. Whatever light the switch is associated with will then dim or brighten accordingly. The switch also offers a night mode that gives you just enough lighting to find the bathroom in the middle of the night.
The WeMo app offers even more, including the ability to review your home’s electricity consumption and control multiple WeMo devices. The WeMo Wi-Fi Smart Dimmer is compatible with Amazon Alexa, Google Home, IFTTT, and HomeKit. Plus, you don’t need a hub, so you can get your smart light switches set up for a low upfront cost.
GE C-Start Smart Switch
The C by GE is a powerful amalgam of minimalist design and easy performance. The plate’s casual design isn’t obtrusive or distracting, but is, in fact, pleasant to look at. Controls are simple touch and drag gestures, and the tiny rings of lights make for an effective (but not overbearing) nightlight.
Scheduling and remote control are handled by the GE C App, but the switch is also compatible with voice commands via Google Assistant or Alexa, giving you many different ways to control it, including options to dim. On its own, the GE C-Start Smart Switch also is incredibly adaptive: It can automatically dim or brighten lights based on the natural light that it detects in the space or if it senses movement in the area.
TP-Link Kasa Smart Wi-Fi Light Switch
As part of the Kasa family of smart devices, the TP-Link Kasa Smart Wi-Fi Light Switch allows for detailed schedule settings via the Kasa Smart app. Users can easily integrate timers and countdowns that the switch will respond to, along with ‘random mode,’ a feature that will throw your lights on/off at random, making it seem like someone is home.
The TP-Link Kasa Smart Wi-Fi Light Switch is a simpler switch than some on our list, but an excellent pick for those who seek minimalist designs, or those who like TP-Link’s devices and want to keep all their devices linked and integrated. It also has great voice control options, offering compatibility with Alexa, Google Assistant, and even Cortana. The Kasa app has a walk-through specifically designed to help homeowners install this switch themselves, which is really something that more smart switches should offer.
iDevices Instinct
There’s nothing better than having a virtual assistant at your disposal. With the iDevices Instinct, a smart light switch with built-in Alexa functionality, that’s precisely what you get. Since Alexa is behind the device, it essentially functions like any other smart speaker using Alexa. From being able to turn on/off various lights connected to the Amazon Alexa ecosystem to checking up on your future calendar appointments, the Instinct does it all. There’s also a blue ring on the switch itself to indicate Alexa’s responses and other functions. The ring also doubles as a handy night light.
What we like about the iDevices Instinct is that it offers additional sensors in the package. For example, light and motion sensors can kick your lights on automatically at certain times of day (or when someone walks by). You also can receive notifications when events happen — like motion detection — even if you’re not home. In short, the Instinct can do double duty as a security system and voice assistant.
Leviton Decora
The no-frills design of the Leviton Decora smart wall switch makes it perfect for someone who is just beginning the process of upgrading their home to “smart” status. The large paddle switch is no-nonsense and straightforward, and the small toggle on the right-hand side makes it easy to adjust the brightness in increments. Thanks to a row of LEDs, you’ll know how much dimmer or brighter you can go. There’s also a small LED on the bottom of the switch, so you’ll be able to find it in the dark — although it’s not so bright as to disturb your sleep.
Got a large room where you want to add a smart light switch? This one by Leviton supports three-way switches, and since it connects straight to your Wi-Fi, you won’t need a bridge. As for the compatible app, you can use it to set how long the dimming LEDs and bottom LED (the one that stays on in the dark) remain on. You also can create schedules for when the lights should automatically turn off or on, meaning you can even use your lighting to wake you up in the morning. Integrate the Leviton Decora smart wall switch with Amazon Alexa, Google Assistant, or IFTTT for a smarter, more connected home.
Gosund Smart Light Switch (4-Pack)
If you’re looking to update your home with smart light switches everywhere, it’s best to have them match. This way, you get an aesthetically pleasing look, as the switches all look the same. Having the same switches also makes it easier to control your lights on the same companion app.
Gosund’s four-pack of smart light switches is an excellent value, and each switch only costs around 10 bucks. You can outfit your entire home with smart switches for less than the cost of one switch from other brands. They don’t require any hub, and they work with Alexa and Google Assistant for voice control. You will need neutral wires to install these switches, and they only work on a 2.4 Ghz network (not 5 Ghz), but installation isn’t too bad. These Gosund switches have a surprisingly good build quality, too, with anti-surge, fire, and UV plastics, and a high gain antenna.
Research and buying tips
What is a smart light switch?
A typical smart light switch has a regular on/off switch, giving it the ability to turn on and off like a regular switch. But, smart light switches also connect via Wi-Fi or Bluetooth to a companion app that allows you to control the switch from a distance. Most smart light switches also allow you to create schedules, scenes, that you can activate using voice control using an assistant like Alexa or Google Assistant, which makes them even more convenient.
How Does a smart light switch work?
A smart light switch usually contains a wireless adapter and connects wirelessly to a companion app (usually via Wi-Fi, but sometimes via Bluetooth). You can connect that companion application to a digital assistant like Alexa or Google Assistant for voice control and centralized control along with your other smart home devices.
Do smart light switches need a hub?
Most modern smart light switches don’t require a hub, but some need a hub to gain full access to the switch’s features. Hubs are becoming less common, and you can find a number of affordable smart light switches that don’t require one.
Can smart dimmers and switches be used outside?
Most smart light and dimmer switches are designed for indoor use only. However, you can find a variety of smart plugs that work outdoors that can control string lights and other outdoor lighting. You can also install a smart switch indoors and use it to control outdoor porch or patio lighting.
