Rated 5 out of 5 by from I LOVE this dimmer! I honestly had no idea that these dimmers existed, but I am so glad that I found this. It was an easy install and had no hiccups when setting up to wifi. I use Alexa to control my lights and dim as needed and the app for peace of mine when we're out and my semi-blind pug is home alone. I have had zero issues since installing a week ago and am planning to buy others for high traffic areas of my house. Amazing product and I highly recommend.

Rated 5 out of 5 by from Smart living! I received the Smart Tru-Universal Dimmer a couple of weeks ago am I’m hooked! Installation was done by a friend of mine, but that was due to my preference. He seems to install it easily and is not an electrician. Set up and connection to my google home was not a problem, and before long, google had yet another thing for me to ask of her (shutting off the light). I love that I can turn on my lights from anywhere from my phone! Great product! Highly recommended!

Rated 5 out of 5 by from Uses an app to control lights! This is for our new home we are building. What I really like about this radiant smart switch is, I can control it from my phone through an app. I don't have to have Alexa or Google products to use this- just the app. I will be able to turn the lights on in my home at any time! This will give me the added security and comfort I want.

Rated 5 out of 5 by from Excellent Easy To Install Dimmer Switch With WIFI I received the Smart Tru Universal Switch With WIFI capabilities and immediately opened and read the instructions on the installation process. I honestly could not believe how easy and quick it was to install. Typically I allow my husband to install things like this, but the directions were so clear I had no issues installing and hooking it up myself. It was very easy to hook up and works much better than I expected.

Rated 5 out of 5 by from smart If you have basic home DIY skills this should be pretty easy for a beginner even after watching videos how to switch out switches. We used this switch for our porchlight, because we have 12 month old and 2 year old, and we always forget to turn it on when we leave. Juggling doorlock in dark with 2 babies is no fun. We have alexa in our car, so we can now just turn on our porch light as we pull up! This is so perfect, we are not sure how we lived without it. Install was very basic and easy. Setting up with wifi and connecting to alexa was very easy. I plan to transition my whole home!

Rated 5 out of 5 by from Absolutely amazing. I loved this inwall dimmer for adjusting lights brighter or dimmer, no need to get out of your chair just select from phone App or Alexa to dim or turn the lights up brighter. The technology is great. Whats not to like about it, in addition you can operate fromswitch itself.

Rated 3 out of 5 by from Good product I have used similar items in the past, and this one I had the toughest time installing. I had to reference tutorials and YouTube plus a fair bit of trial and error to get it working. Hopefully your install is easier than mine was.

Rated 2 out of 5 by from Needs work I have had this for about 2 months now and it is a very finicky switch. It was easy to install but very difficult to get it to sync with the app. Once it is synced it may lose connection about once a week. It has gotten somewhat better but hoping for better stability

Rated 5 out of 5 by from EASY TO INSTALL DIMMER I am happy with this dimmer because not only it has a pretty nice packaging,it also exceeds my expectation.I can able to control my lights at home to save energy.This dimmer is made with high quality as well.

Rated 3 out of 5 by from Nice voice control! The switch looks modern, simple and refined. The switch works well, but it would be nice if the dimmer slider was easier to use and had a better tactile response. It's great setting up schedules for the lights via my phone, and dimming or brightening them an app via my phone. My biggest issue with this was the setup. It wouldn't connect to WIFI at first, and after two weeks of use it disappeared. I think as the company works out bugs with the app it will run smoother. So far it's been running great with several schedules throughout the day. This is a great plug if you want WIFI built in. Just make sure you know how to install a plug, and are OK with setting up devices via your WIFI network. Also, you need a QR code scanner on your phone/device to link the plug to the app.

Rated 5 out of 5 by from Easy to install! If you're looking for a smart light that is easy to install, this is it! After installation, the app lets you control your lights from anywhere - not only will you have a great aesthetically pleasing switch, but the comfort and ease of being able to turn on/off & dim your lights from your fingertips!

Rated 4 out of 5 by from Great product! I've been using this product for over a month. It's very simple to install and can be used with Alex to turn the lights on or off and to dim them. I have had a problem with it disconnecting and having to reinstall it to get it to work with my Echo Dot. Not sure what's causing that, but I do love it anyway. I can turn the lights on/off hands free and don't have to enter a dark room anymore.

Rated 4 out of 5 by from Good Design I have been using this for more than 3 weeks. Installing in wall dimmer was easy just had to replace my existing switch. I like the fact that Once i setup the device it was really easy to use and worked without any issue with app and google home. There is a slight delay between pressing and change but still really good. I would prefer if the added IFTTT or z-wave support so that it works with existing home system.

Rated 5 out of 5 by from Sophisticated lighting, top notch quality! I had the opportunity to try Legrand's Radiant Collection Smart Lighting, In-Wall Dimmer Switch in my home. The Radiant Collection combines innovation with elegance in order to meet traditional lighting needs in your home. Installation and set up of the Radiant In-Wall Dimmer Switch was straight-forward when following the wiring schematics provided within the written instructions (access to video installation is also available). This particular switch can be utilized on both a 2-pole and/or a 3-pole platform, depending upon the location and setup of your homes wiring plan. The Radiant In-Wall Dimmer switch features a classic look in solid white, and is easily powered on by the touch of a paddle switch. The dimness is controlled by a push-switch adjacent to the larger paddle switch. Radiant lighting takes a step into the modern world when utilized in conjunction with the Radiant Smart Lights app, which is an intuitive platform that enables a user to control their lighting via smartphone. The Smart Light app is compatible with the entire Radiant Lighting Collection, and provides the opportunity for users to control a single light/outlet or to control specific groups of lighting after scanning the QR code on a specific product. Additionally, users on the Smart Lights platform have the capability to set lighting schedules and to create specific lighting scenes to meet personal lighting needs throughout the day. The Radiant Collection In-Wall Dimmer Switch has transformed my kitchen. Products in this collection are compatible with various smart hubs (e.g. Alexa, Google Assistant, etc.), making the ability to control lighting in your home nearly effortless. I highly recommend this product if you are looking for a high-quality, modern update to your current lighting scenario.

Rated 5 out of 5 by from It’s a Great Buy! I was able to sample the dimmer switch and it exceeded my expectations! It was easy to install and also easy to use with the app and my smart speaker. I would definitely recommend this product to anyone looking for smart switches.

Rated 4 out of 5 by from Great for mood setting! I'm very happy with this dimmer switch. Installation was easy and it worked as expected. Integrates well with AI assistants and fits well with my decor. This switch is ideal if you like to set different lighting moods for different times of day/occasion. I did run across a few instances where it didn't remember programmed settings but I attribute that to voltage spikes from my power company.

I have an older home with 2 wire electrical. Will these dimmers work with that wiring?

Asked by: Scott
The SmartLights dimmer will require a separate Neutral wire to function properly so it will not work if you only have 2 wires in your electrical box.

Can you change the phase of the wwrl50 from forward to reverse without using the smart phone app? The app continuously closes when I try access the device settings.

Asked by: GregS
The only way to change the dimmer phase is through the app. I would suggest contacting Tech Support to help trouble shoot your APP issue. Radiant products 1.800.223-4162 opt 3 Mon - Fri: 8am - 8pm EST (excluding holidays) Email Us -

If I intended to only dim from one location can this switch be used with conventional Legrand three-way switches.  This is how my existing Legrand sliding dimmer switches are wired. 

Asked by: Disappointed
The Smart Lights dimmer(WWRL50WH) can only be paired with the HMRW(remote dimmer) for a 3way application.
