To the uninitiated, a smart dimmer switch might sound like a contradiction in terms. In reality, it's a simple and convenient way to control the ambient lighting in your home, and there are several reasons why you might want to consider installing smart dimmer switches of your own.

Many smart switches allow you to control the lighting at home in a number of ways: through voice control, a smart app, or with a simple swipe of your finger.

You can preset favorite lighting settings for different occasions, saving time when such an occasion arises. App control lets you arrive home to a warm-looking, pre-lit house, and timers can of course be set at regular intervals - should you be away from home for any length of time.

Smart dimmer switches can also help you to achieve a greater level of energy efficiency at home, potentially reducing your impact on the environment and possibly even saving you some money too!

Here are the best smart dimmer switches you can buy right now.

Interestingly, this switch doesn’t rely on Wi-Fi to work, so you won’t experience any dip in performance, should your Wi-Fi go down at any point.

You will need the Lutron hub to operate this smart switch, however, as the Lutron app will not work with third-party hubs. Luckily this is included in this switch kit, so this shouldn’t cause any issues. In addition, there are four different ways to install this switch, giving you maximum flexibility.

Choose from single pole, wireless three-way, adding a second switch anywhere, or adding wireless multi-location, depending on what you’re looking for.

This smart dimmer switch can be controlled from the wall, via the remote control included in the pack, via the Lutron app, or with voice control. This Lutron Caseta kit also boasts compatibility with more leading smart home devices than any other brand, including Alexa, Google Assistant, Apple HomeKit, Serena Shades, and Sonos.

As this product does not require a neutral wire as part of its setup, it can therefore be installed into any home of any age. You should find that it works seamlessly with your current wiring, so you will save a bit of extra time and expense should you choose these switches.

Using the Lutron app, you can create personalized schedules to suit your routine at home. You can set lighting scenes across multiple lights, save these settings, and return to them whenever you like with the simple press of a button.

Adjust your lighting set up for different seasons, or simply create favorites to suit different activities; reading, watching movies, family dinners, and so on. Once you’ve set these up you can enjoy the perfect level of lighting whatever you’re doing, without having to fiddle with the dimmers each time.

The icing on the dimmable cake is that this Lutron Caseta smart switch is also compatible with over 500 types of dimming LED bulbs. With two smart switches included, you’ll be well on your way to achieving the perfect smart lighting setup for your home.

Lutron Caséta Deluxe Smart Dimmer Switch

Twice as many smart switches for a fraction of the cost as the Lutron Caseta dual pack, this four-pack kit from Treatlife is a solid alternative for anybody wanting to install smart lighting, yet isn’t perhaps as fussed about having the same levels of functionality.

In terms of what it can do, this Treatlife smart dimmer switch has voice control compatibility and works with Alexa or with Google Home Assistant. It doesn’t require a separate hub to function, and lighting can be fully controlled and customized via the TreatLife app.

Use the app to set timers, lighting levels, scenes, and so on; which can all be stored for your convenience. The Group Control function also allows for multiple users to share control of the lighting via the app; which is good news for the harmony of the home, as you’re not relying on one user being the gatekeeper of the smart lighting!

The switch is compatible with most non-smart dimmable LED bulbs with a 150-watt maximum, and its standard size will fit any standard multi-gang wall panel. An easy-to-follow installation up guide will walk you through the wiring process as well.

On the downside is the fact that this smart switch is only suitable for single pole set-up, and won’t work for three-way poles. As such, it’s not possible to have one light controlled by two switches, for example.

So, if you have two switches that control the same bulb—such as a landing light that can be manually switched on or off via a switch on the same floor, and one on the floor below—this might be a bit of a kicker for you.

However, provided that single pole set-up works for you and your home, this may not matter very much to you. You’ll get four smart dimmer switches with this pack and a decent level of smart functionality as well.

Key Features
  • Includes 4 smart dimmer switches
  • Voice control
  • Set schedules and scenes
  • Timer function
  • 1 to 100 dimming range
  • Group Control function
Specifications
  • Brand: Treatlife
  • Neutral Wire Required: Yes

This single-pole smart dimmer switch from Kasa is a good option for anybody looking to introduce smart lighting into their home but may be slightly restricted in terms of their budget. There’s a reasonable trade-off between function and value here, and as such it’s a worthy contender for consideration.

Voice control via Alexa and Google Home Assistant provides you with a hands-free experience, and you can set lighting schedules via the Kasa Smart app. Control the brightness, and set lighting scenes for ambiance from anywhere.

Timer functions also allow you to switch lights on remotely. Perfect as an extra home security measure if you’re not at home, and also makes things that much warmer and more inviting when you do return.

There will be a few more steps involved in the installation as you will need to check for and use neutral wiring for this smart switch. Depending on the age of your home, you may or may not have this, and you should therefore check first before parting with your cash.

However, there’s decent functionality here for comparatively less money than other smart switches, so long as the single circuit set-up works for you.

Kasa Smart Dimmer Switch HS220

This hub-less, single pole, neutral wire requiring, smart dimmer switch pack from GHome comes with four smart switches included and represents very reasonable value for money for anybody wanting to introduce smart lighting throughout the home.

Voice commands can be issued via Alexa or Google Home Assistant, and a manual slider function on the switch itself enables you to increase or reduce brightness levels with a swipe of your finger.

Control every aspect of your home lighting with the Smart Life app, to give your home that air of elegance. There is a one to 100 dimming range, so you can set brightness levels in any room to whatever percentage you desire with ease.

Timers can be set for any situation, and brightness levels can be automatically set to increase gradually over a pre-set length of time. A handy feature for anybody who might need a little bit of extra encouragement to get out of bed in the morning, perhaps?

Countdown modes are accessible via the app as well, so that lighting can be set to reduce gradually until they eventually switch themselves off. Useful for saving energy if you have children that prefer the light to be left on while they nod off to sleep, as you’ll use up fewer units this way than by having lights remaining on throughout the night.

Set your own lighting scenes and share control with the whole household, using the Group Control function. And monitor the lights at home from anywhere with the app, so you’ll never have to arrive home and discover you’ve left the kitchen light on all day, again!

GHome Smart Dimmer Switch

This single switch pack from GE Brighten is three-way compatible, so you can integrate it into multi-switch setups if you wish. You can add up to four add-on switches to the same device, which is a useful feature if you’re looking to install smart lighting everywhere in the home.

There’s voice control via Alexa or Google Home Assistant, but you will need a Z-Wave-certified hub to use this. Luckily, this includes a large range of products so you shouldn’t have to look too hard to find one that’s compatible.

Neutral wire installation is required, so again you will need to check the current set-up in your home, as this device will not work without it. However, once installed, you can easily control your lighting via smartphone, tablet, or PC.

Schedule the lighting for preferred times of day, adjust the brightness settings, or set timers and scenes easily, from anywhere. This product contains ample functionality and has everything you could reasonably expect from a smart dimmer switch.

It works with all non-smart dimmable LED, CFL, halogen, and incandescent bulbs, and has a full range of dimming from 0-100 percent.

The main downside is the requirement of a separate hub for operation, which is not included. Not necessarily a deal-breaker in itself perhaps, just something for consideration.

Key Features
  • Supports multi-switch set up
  • Voice control
  • 0 to 100% dimming range
  • Fully customizable app functions
Specifications
  • Brand: GE Enbrighten
  • Neutral Wire Required: Yes

GE Enbrighten Z-Wave Plus Smart Light Dimmer

There are a few details to mention with this Martin Jerry single-pack smart dimmer switch, which may influence your decision positively or negatively, depending on what you’re looking for.

Firstly, this is a single-pole dimmer switch and will require a neutral line for operation. Multi-switch setups cannot be achieved with this product, so if this is something that you’re looking for, you might want to seek out an alternative.

Secondly, this smart switch allows for mains dimming only. This can be controlled via the SmartLife app on your phone, or through voice control via Alexa or Google Home Assistant. Shared control can be given to other family members, though scheduling functions are somewhat limited in comparison to other smart switches.

On the plus side, there’s no hub required, and this is a durable product made from fire-rated plastic, which should reassure any potential buyers of its quality. It should also work with any non-smart, dimmable LED and CFL bulbs.

This product would suit anyone who wants to install smart lighting at home but is not looking for some of the associated functionality of other brands. Limited functionality in terms of its features (absence of scene-setting, etc.), but perfectly serviceable as a means of dimming the lighting via voice control or remote/app control, and for making your lighting more energy efficient.

Key Features
  • Compatible with Alexa and Google Assistant
  • Fire rated plastic design
  • 100,000 button press tested

FAQ

Q: What Is a Smart Dimmer Switch?

A smart dimmer light switch is a replacement for a traditional built-in light switch on your wall that works by sending wireless signals through your home Wi-Fi or mesh network.

These switches control your lighting, ceiling fans, or anything connected to that switch and even adjust your lights' brightness.

Q: Are Dimmer Switches a Good Idea?

Yes. With a dimmer switch, you can reduce the light output, which helps the light bulbs last longer. This also means you don't have to replace the bulbs as often. As a result, dimmer switches can help you save on your utility costs and minimize the costs related to replacing the bulbs.

Q: Besides Energy Efficiency, What Other Reasons Are There for Installing Dimmers in the Home?

Dimmable LED bulbs are perfect for creating mood lighting, that's when they come into their own. They're also ideal for living spaces, bedrooms, and accent lighting. For movie nights-in or romantic meals, dimmable LED bulbs can be all you need to set the perfect atmosphere.
