The Buyers Guide To The Best Smart Dimmer Switches

If you’ve made it to this section, you must be on the fence about which switch to choose. And that’s OK, as I said before, there are too many poor switches out there.

So, I’m going to give you a helping hand to find the best smart light switch, by the end of this section you’ll know exactly what you should be looking for. Sound good?

Great, let’s get started:


Setting light schedules can come in handy for a few reasons; my favorite use is for vacations. You can set the lights to go off on at various preset times, warding off any potential thieves. And while you're at home, you can set the smart switch to you.

Hub Required

Some smart dimmer switches require a hub to control the system, which can make it the expensive option if you do not already own one. But, if you do have a home hub, you'll need to make sure it's compatible with all your smart home devices to avoid disapointment.

Neutral wire required

If you live in a house that was built pre-1980's, there's a chance your home doesn't have a neutral wire. Some smart dimmer switches require a neutral wire to operate, buying the wrong switch could result in you calling out an electrician.

Control Options

The majority of smart dimmer switches will not work with a three or four-way lighting system. Which makes this something you need to think about before you purchase a smart switch. Think, "Do I need two switches to control one set of lights"?


Adding geofencing to your smart light switches can open a whole world of possibilities. Geofencing allows you to program lighting commands based on your actual location. For example, you could have it set for the driveway light to turn as you approach your house.

Voice Control

Voice control isn't a pre-requisite of a smart dimmer switch. If you're looking to add voice control to your light bulbs, then you better make sure it's compatible. In the list below, I've got something for any of the principal voice assistants.

And finally, the warranty:

Certain Z-Wave and Homekit switches can be costly; the lasts thing you want is it breaking. If you’re unfortunate enough for this happen, it’s nice to know the manufacture has your back.

The Best Smart Dimmer Switches

By now, you should have a good idea of what you’re looking for, and that’s the essential step. Now its time to find the right smart light switch for you. 

Below are five of the best dimmer switches; each one will offer important features, but are they the right features for you?

#1 – Lutron Caseta Smart Lighting Dimmer Starter Kit


Lutron Caseta

Lutron’s smart dimmer starter kit is compatible with all major brands of voice assistant Amazon Alexa, Google Assistant, HomeKit, and much more.

They are compatible with so many devices that no other smart switches can compete with them.

They claim to be a very easy dimmer to install, only requiring a screwdriver to get installed. 

With no neutral wire to connect, it takes three easy steps. Once the smart light switch is connected and ready to go, you can start scheduling. 

This allows you to schedules based on your routine or use their smart away plan; this turns the lights on and off randomly.

It includes geofencing capabilities through the App by creating lighting solutions based on your location. 


From one dimmer switch, you can control up to 17 dimmable bulbs. You can do this by creating groups or setting scenes for particular bulbs.

Key Features

  • Geofencing
  • HomeKit compatible
  • Voice Control
  • No neutral wire required
  • Can control 17 bulbs
  • 1-Year warranty

What Other People Say

They’ve been using this switch for the past few months and were very impressed with its versatility. It was great having a massive selection of voice controls to pick from. The whole thing worked seamlessly, but they did mention you need a little electrical knowledge to get it started.

Another user said this was the perfect dimmer switch if you’re looking for a complete home system. They had no trouble installing and connecting the light switches; it took them around 20-minutes. All in all, the majority of people would recommend it.

Final Verdict

Lutron is one of the most advanced dimmer switches on the list, and this comes down to compatibility it offers. And because of this, it allows you to make some pretty cool lighting solutions. For example, a motion sensor turning lights on, Amazon Alexa and Google Assistant, or carbon monoxide alarms that turn your lights on.

Another stand out feature for me was the Lutron App; everything was neatly laid out and looked clean and crisp. If you enjoy building complex smart home systems, this is an excellent option for you.

If you’re looking for a Z-wave light dimmer, then this is the one for you. 

It’s about half the price of any of its competitors and offers just as good if not better functionality. 

Due to the Z-Wave compatibility, it can connect to multiple smart home hubs, including SmartThings and Wink.

The installation is made more accessible because of the lack of neutral wire, although you may have to purchase a bypass in some cases. 

It’s compatible with Amazon Alexa and Google Assistant, so you’ll have no trouble adding voice controls to your smart dimmer switch.

You can also get third-party devices to perform lighting actions based on certain triggered events. 

This particular dimmer switch can be configured into three control options, including 3-way to 5-way. The RGB LED notifies you of actions being performed, scene selection, and remote energy monitoring.

Key Features

  • Creates Scenes
  • Connects to Z-wave hubs
  • Remote energy
  • Built-in configuration button
  • Google Assitant and Amazon Alexa
  • No neutral wire required

What Other People Say

They loved how well it worked with there SmartThings home hub. And they were also very pleasantly surprised with how cheap it was considering it’s Z-Wave capability. Using their smart hub made it very easy to configure all the different settings.

Others said it was the easiest Z-Wave dimmer to install out of all the ones they owned. So far they have a few dimmer switches littered throughout the house, they just wished they were all Inovelli. The smart switch could fit in the wall socket better than other brands, and they didn’t need a neutral wire.

Final Verdict

It was effortless to set up with a SmartThings hub, and the fact that there was no neutral wire made it even easier to install. One thing to mention was they suggest using a bypass by Aeotec; if loads that under 25W, and to open more control options, you can also install an AUX switch.

The problem is adding these things costs time and money, whether it’s worth it down to you. But, ask yourself this question “Am I willing to spend hours playing with all the fancy features?” If the answer is yes, then this is 100% the smart light switch for you.

What We Liked

  • Price is great
  • Easy to configure
  • Maintains a three-way connection

All you have to do is utter the words “Alexa/Google set lights to 50%”; the action will be completed.

What Other People Say

They’ve had the dimmer switch for some time now, and so far, they were delighted with the performance. The physical installation was straightforward. Compatibility-wise they had theirs connected to a SmartThing home hub, which they said worked fantastically.

Another customer said they had to place some wiring to get the dimmer to work; this was because they had no neutral wire. Once everything was set up, it was a breeze to get the whole thing set up and configured. They loved being able to turn on their lights with Amazon Alexa but felt the percentages didn’t match the actual brightness.

Final Verdict

It’s an incredibly cheap light switch, which is made better by the fact you can link it to your Google Home Hub or Amazon Alexa devices. The touch sensitivity was very responsive and gave you great control over your smart light dimmer.

There was one problem I found; the off button wasn’t isolated from the dimmer. This meant you could quickly turn off your lights instead of dimming them. Overall it’s an adorable, smart light switch, but it was let down by its little design fault.

What We Liked

  • Very easy to install
  • Alexa grants it Zigbee communication
  • Responsive to Alexa and Google Assistant.

What We Didn’t Like
