Rated 3 out of 5 by from Helpful I have tried both the plug-in and in-wall devices from this company and while I like both products, I prefer the plug-in type for simplicity and portability. I had a bit of difficulty getting them to sync up with the app initially but after some troubleshooting, got it figured out. The compatibility with my Alexa devices was a must and they work great.

Rated 5 out of 5 by from Absolutely Awesome Dimmer I purchased this dimmer as a replacement for some some other smart wi-fi dimmers I have in my home. After having installed and used the Legrand dimmers for a couple of months, I can now say that I intend to replace all of my existing wi-fi dimmers (approximately 50) with Radiant - Smart Tru-Universal Dimmers. Without taking time to discuss my complaints with the other dimmers I will say that the Legrand dimmers address every one of my concerns with the other product. In particular, here is what I like about the Legrand dimmers: - Works seamlessly with Homekit. The setup was totally uneventful (what a difference!). - Connects directly to your home wi-fi without the need for a bridge. - Powered directly off of wall current and doesn't require batteries. - Works in 3-way and 4-way applications. When used in conjunction with the Legrand Remote Dimmers it can control multi-way switch installations. And the remote dimmers do not require batteries or the use some weird bluetooth signal. - All of the wiring connections are internal to the switch housing and not exposed on the outside of the housing - this practically eliminates the possibility of accidentally shorting one of the connections on the dimmer against the ground wire in the junction box. - Does not require the use of a traveler wire between the the main dimmer and the remote dimmers in multi-way installations (this means that you don't have to be a rocket scientist to wire multi-way switches). - The dimmers seem extremely stable and have never lost their connection to my home wi-fi. After having struggled for a couple of years with my existing wi-fi dimmers, I am totally impressed with the Legrand product. I hope they continue to grow and expand their product offerings in this area!

Rated 5 out of 5 by from Great functionality and easy to install! This product was super easy to install and integrate with Alexa, the instructions in setting the Smart Switch with our home network were very easy to follow and everything was up and running in a manner of minutes. Being able to remotely control the lights is very convenient, you can also manually click it on or use the app which is great. It is also still able to be used as a normal switch. The Wi-Fi smart switch looks almost identical to the other switches in our home with the addition of a nice small cool white led to show the switch is off and helps find it in the dark. This was a great addition on our journey to a smart home.

Rated 1 out of 5 by from I tried... I received the Smart Try Universal Dimmer, WiFi, white from Try It Sampling. Myself and my spouse, who is a certified electrician, attempted to install the device in our bedroom, but without success. There were two pieces missing from the kit that are required to have the dimmer fully functional. There is no way I could 've even gotten that far alone, so this was an unsuccessful sample and I believe it would be for many people who aren't "certified" electricians. Thanks for the oppritunity, though.

Rated 1 out of 5 by from Need a refund I bought the dimmer switch. I tried to set up the smart connect for 3 days and was unsuccessful. I downloaded every app possible to connect to the device. The smart light app asked for a QR code that it did not come with... waste of money. Also, the red light has consistently blink when the light is on!!! Smh

My contractor installed this, caulked the switch plate, and threw away the packaging. So I cannot get to the QR code very easily to set up wifi. What is a workaround for this? How can I connect to wifi without the QR code on the switch?

If I use this in a 4 way, do I need to add remote dimmers to the other switch locations or can I just use this one dimmer and regular switches in the circuit?

Asked by: Jules1
The WWRL50 master dimmer has to be used with remote dimmers(HMRTC or HMRW) in the other locations.

How do I set this up for google home? I used the Legrand Smart Lights WiFi app to set up the dimmer but its not in the choices for google..

Asked by: twinte3
Thanks the issue is I did just that and I now get a "something went wrong" prompt every time I try to turn it on from google home. It worked one time right after setup, and then didn't and hasn't.

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.
