Pros

  • Feature rich
  • No neutral wire needed
  • Smart assistant integration

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 Lutron Caseta wireless dimmer. 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.

GE

GE C-Start Smart Switch

Motion sensing

Pros

  • Helpful motion sensor
  • Sleek, unobtrusive design
  • Doesn’t need neutral wire

Cons

  • Must be in Bluetooth range for setup
  • Adapter required for three-pole installations

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 rather 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

TP-Link Kasa Smart Wi-Fi Light Switch

Security-conscious

Pros

  • Elegant wiring design
  • DIY walk-through via app
  • Random lighting mode to simulate occupancy

Cons

  • Large wall plate
  • No HomeKit support

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

Alexa inside

Pros

  • Works with three-way switches
  • Includes additional sensors
  • Works with smart speakers

Cons

  • Some connectivity problems
  • Neutral wire required

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.

Frequently Asked Questions

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 and scenes that you can activate using voice control via 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.

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 your outdoor porch or patio lighting.

Can you make a smart light switch?

Yes, there are a number of ways to make non-smart lights into smart lights. You can make your lights smart by using smart bulbs, smart plugs, or using instant products like Switchmate.

Can you dim lights with a smart light switch?

If your smart light switch and bulbs have dimmer capabilities, you’ll be able to dim the lights. However, you won’t be able to dim your lights if the hardware doesn’t support that feature.

How do you install a smart light switch?

Most people can install a smart light switch in an afternoon. However, keep in mind that most smart light switches require a neutral wire for installation. You should have neutral wires if your home was built after the 1980s. If you have an older home, you might need to find a smart light switch that doesn’t require a neutral wire, like the Lutron Caseta Switch.

Where can I buy a smart light switch?

You can find smart light switches on Amazon and at big-box retailers and hardware stores like Best Buy, Walmart, and Home Depot. Amazon probably has the most comprehensive collection of smart light switch products, though.
