The Lutron Caséta Smart Switches are the best you can buy, especially if you're looking for a remote-controlled whole-home smart lighting system.

Best In-Wall Smart Switch for Apple HomeKit
Lutron Caséta Smart Switch (PD-6ANS)

Lutron’s Smart Switch is the best for Apple HomeKit because it is one of the simplest Siri-enabled switches we’ve ever installed. It’s reliable, accurate, and, in addition to lights, the 120-volt switch is also suitable for use with ceiling and exhaust fans (something not all smart switches can do). It’s wired for single-pole installations, but can be converted to a three-way switch using the Lutron Pico Remote.

It does require a hub, something we aren’t normally advocates of, but if whole-home smart lighting is what you're after, the additional hardware is a great investment. A neutral wire is also required for installation.

We love the Lutron because of its versatility. The switch supports useful lighting features like geofencing, scheduling, and auto-off timers. You can manage your entire Lutron Caséta lighting system from an Apple Watch—a cool feature for managing your smart lights on the go. There are plenty of great picks on our list, but Lutron’s smart switch remains king.

Pros

  • Geofencing

  • Works with Alexa, Google Assistant, and Siri

  • Supports many smart home ecosystems

Cons

  • Hub required

Best Smart Dimmer for Apple HomeKit
Lutron Caséta Smart Lighting Dimmer Switch Starter Kit

Lutron's Caséta Dimmer Starter Kit system is a reliable, versatile, and intuitive choice for your Apple HomeKit ecosystem. It’s one of the few dimmer switches that doesn’t require a neutral wire, which is often absent in the electrical wiring of older homes, making it a stellar choice no matter where you live.

The starter kit comes with the required hub and Lutron's Pico Remote that can be used to control the lights when you're at home (in addition to Siri voice control and the Home app). You can also control the dimmer switch from an Apple watch. It’s responsive and offers one of the easiest and fastest setups of any HomeKit dimmer switch we tested.

Like other Lutron switches, the dimmer can do things like Away Mode, which turns the lights on and off at random times when you're not at home, and geofencing, which adjusts the lights based on your location. Overall, Lutron’s versatility and ease of use make Lutron a brilliant choice for Siri.

Pros

  • Works with Alexa, Google Home, HomeKit

  • No neutral line requirement

  • Geofencing

Cons

  • Hub required

How We Tested HomeKit Smart Switches and Dimmers

The Tester

Hi, I’m Rachel Murphy, Reviewed’s resident smart home expert. I live in a home full of smart speakers, home security cameras, smart lights, appliances, and more connected gadgets that work with smart assistants like Alexa, Google Assistant, and Siri. I’ve tested just about every smart home gadget you can imagine, but smart lighting is the category I interact with the most daily. For this guide, I spent hours with each switch, as well as plenty of time getting to know my breaker box and learning how to wire smart switches and dimmers.

The Tests

To adequately test these switches, I installed the switches and dimmers throughout my home and connected them to an Eero Mesh Wi-Fi router. I evaluated their setup processes, apps, physical and digital performance, smart home ecosystem integrations, remote control capabilities, and how well they work Siri. I lived with these products to figure out how they work on a day-to-day basis, just as you’ll be using them.

What You Should Know About Smart Switches and Dimmers

What is Apple HomeKit?

When it comes to the world of smart light switches and dimmers, there are lots of different options to choose from. If you’re buying new smart switches and dimmers for your home, first consider whether or not the switch or dimmer is compatible with your current smart home setup—especially if you use Apple’s HomeKit.

HomeKit is a popular voice-controlled platform that lets you manage your compatible smart home devices (like smart switches) using Siri, a virtual assistant embedded into Apple’s operating systems. This can be done using the Home app on your mobile device or via the HomePod Mini smart speaker, which functions similarly to the Amazon Echo and Google Home smart speakers.

If you’re already an Apple user, you’ll find the integration of Siri to control your smart switches easy to use. You can even use the switches to control bathroom fans, ceiling fans, humidifiers, garbage disposals, and outlets.

One final, but important, note is that an Apple Home Hub like the HomePod Mini is needed to control the smart switches and dimmers via the Home app when you're away.

Do I Need Smart Bulbs or a Smart Switch?

Replacing every light in your home with smart bulbs can get expensive quick (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 chandellier'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 it would be to simply install the cheapest smart bulbs, but your dimmer switch will never burn out or 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 Siri to turn on the light, but somebody turned the regular light switch off without thinking, and therefore your smart bulbs are off-line and there you are just screaming into the darkness for no reason. Not that we have ever experienced anything like that.

Smart bulbs might be a more attractive starting point for those who want to ease their way into smart 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, but it's generally just less fussy—and tech that's less fussy is something we could all use a little more of.

Things to Consider When Looking for a HomeKit-Compatible Smart Switch

1. Compatibility

As you shop for smart switches that work with HomeKit, there are a few things you should keep in mind. First, remember to check the product to see if it is even compatible with HomeKit, as many smart home devices aren’t. To determine whether or not a smart switch is compatible with HomeKit, look for the words “works with Apple HomeKit” on the product’s packaging or in the product description.

2. Devices you already use

Check to make sure the smart switch is congruent with your mobile phone or tablet. For example, certain smart switches, like the Leviton Decora Smart Switch, are only compatible with iOS devices, while others are more compatible across various platforms. This is especially important if not everyone in your household uses iOS devices.

3. The right bulbs

You don’t need a smart bulb or smart lighting to make your smart switch work. Most smart switches work just fine with the fixtures and bulbs you already have installed in your home. But you do need a hub like the Apple HomeKit system to operate our top picks listed above.

The good news is that most smart switches, like these options listed above, function just like a traditional wall switch when you don’t want to use their high-tech capabilities. However, if you use the smart switches for their intended purpose, you'll find turning the lights on and off more convenient than ever before.

Privacy and Apple HomeKit

There’s always a security risk when using internet-connected devices at home, but there are ways you can protect your privacy when using HomeKit devices. Apple claims that all HomeKit user data is encrypted end-to-end locally (meaning on your Home Hub) before being transmitted to the cloud so that no one has access to it but you. According to the company, HomeKit's infrastructure uses iCloud, iOS, iPadOs, and macOS to "protect and sync private data without exposing it" to others, including Apple employees. To secure your account further, turn on two-factor authentication and make sure your password is unique and hard to guess. You can read more about Apple's HomeKit data security policy.

One thing to know is that Apple, by default, keeps your Siri voice interactions (one of the primary ways to control HomeKit accessories) and may review the audio clips to help improve Siri’s accuracy. You can opt-out of this by turning off Siri and Diction in the Settings > Privacy > Analytics & Improvement > turning off Improve Siri & Dictation. To delete your Siri voice history on a HomePod Mini, open the Home app, press and hold the HomePod Mini icon, select Siri History, tap Delete Siri History, and confirm the deletion. To delete your Siri voice history on an iPhone or iPad, open Settings > Siri & Search > Siri & Dictation History > Delete Siri & Dictation History. For more information, check out Apple’s Siri dictation and privacy disclaimer.


Other Smart Switches for HomeKit We Tested

Wemo Smart Light Switch (second-gen)

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 with Siri.

This switch is for single-pole use only and a neutral wire is required. Automation features like scheduling, an auto-off timer, Away Mode, and remote control are available with this switch. 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.
The Wemo Smart Light Switch is a reliable, no-fuss option that works with Siri voice control to control your incandescent, halogen, CFL, fluorescent, and LED bulbs.

Pros

  • Attractive design

  • Works with Alexa, Google Assistant, and Siri

  • Reliable

Cons

  • App lacks two-factor authentication

Meross Smart Switch

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 Siri voice commands and via remote control in the Home app.

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. It doesn’t feel as luxurious as our No. 1 pick for Apple HomeKit smart switches, but the Meross Smart Switch is still a great choice for controlling your lights.

Pros

  • Works with Alexa, Google Assistant, and Siri

  • Comes with helpful wire labels

  • Reliable

Cons

  • App lacks two-factor authentication

  • Budget build quality

Eve Light Switch

The Eve Light Switch exclusively works with Apple HomeKit. Aside from great performance, the switch is also one of the most aesthetically pleasing to look at, and the touch on/off is slick to use. In addition to Siri, you can also use an Apple Watch to control Eve's smart wall switches.

A neutral wire is required and does not work with three-way switches. 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 fantastic option if you need a smart switch that's sleek, modern, and designed specifically for the Apple HomeKit ecosystem.

Pros

  • Works with Siri

  • Two-factor authentication available via iCloud

  • Attractive

Cons

  • No support for Alexa or Google Assistant

Leviton Decora Smart Wi-Fi Switch (second-gen)

The new generation Decora from Leviton streamlines everything into a single switch for hands-free voice control with 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 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 Apple HomeKit. We did experience some connectivity issues with this switch, but overall it’s easy to use and works with Apple HomeKit.

Pros

  • Work with Alexa, Google Assistant, and Siri

  • Great build quality

  • Slimmer than other switches

Cons

  • Unreliable connection

  • App lacks two-factor authentication

Other Smart Dimmers for HomeKit We Tested

Product image of Meross MSS560 Smart Wi-Fi Dimmer Switch
Meross MSS560 Smart Wi-Fi Dimmer Switch

The second-generation Meross Smart Wi-Fi dimmer is a value-packed HomeKit switch that makes for a very enticing option for the price. It won us over thanks in part to its clear-as-day instructions and handy wire-label sheet. If you’ve never rewired a light switch, the Meross single-pole dimmer is a great place for beginners to start, though be aware that it requires a neutral wire.

The physical switch has two buttons that can be toggled up and down, but they only adjust the brightness at 20% increments at a time, so you'll need to rely on Siri or the app if you don't prefer one of the five brightness settings. It also does not offer customizable fade on/off rates.

Despite those minor shortcomings, this is an easy investment that’s well-built and isn’t loaded with potentially confusing bells and whistles, making it a good choice for Apple HomeKit novices.

Pros

  • Works with Alexa, Google Assistant, and Siri

  • Quick and simple installation

Cons

  • No custom fade rates

Leviton Decora Smart Wi-Fi Dimmer (2nd Gen)

Leviton’s second-gen dimmer switch is a notable upgrade over its predecessor, offering compatibility with Apple HomeKit (as well as Alexa and Google Assistant) in a single switch that supports both single-pole and three-way connections.

We had no problems integrating the dimmer switch with Siri and using voice control to dim the lights during our tests. New to the second-gen switch is compatibility with August, Yale, and certain Schlage smart locks, so you can add lighting controls based on the status of your door lock.

Like most smart dimmer switches, a neutral wire is required. One downside to the physical switch itself is that the dimmer slider pops out partially, so you need to give it a gentle push back to secure it. But, it performed well during our tests, and we think it would make a reliable option for any HomeKit household.

Pros

  • Works with Alexa, Google Assistant, and Siri

  • Supports three-way or single-pole

  • Easy setup

Cons

  • Materials feel cheap

Wemo Wi-Fi Smart Dimmer Switch (second-gen)

It took us several attempts to get Wemo’s second-gen smart dimmer switch up and running, but once we did it was smooth sailing from there. The Siri-compatible switch has one of the most satisfying digital dimmers around, allowing you to slide your fingers up and down the switch to control the brightness of the overhead lights. Like others in our guide, the single-pole switch requires a neutral wire for installation.

One thing to know about the switch’s design, which might not be evident to the naked eye, is that it works with single and multi-switch rocker switch plates, but it does not fit with metal faceplates. Despite the setup headaches, Wemo’s dimmer switch is a solid and reliable choice that’s full of features like schedules, timers, and night mode (when the lights turn on to a lower light level during certain times), and plays nicely with Apple HomeKit.

Pros

  • Works with Alexa, Google Assistant, and Siri

  • Satisfying digital dimmer

  • Great features

Cons

  • Connectivity issues during setup
