Pass & SeymourLegrand Radiant WWRL10WHCCV2 Enabled, White Smart Wi-Fi Switch,

As far as the actual hardware goes, these things seem pretty solid. Easy to install if you understand how switch wiring works. I can install one in about 15 minutes now, after having installed 5.A few gripes: the software occasionally reverses the state of the switch in the Android app. The switch itself is unaffected by this-- but sometimes I have switches reporting as on in the app when they are actually off, and vice-versa. This gets even more annoying when I try to use Alexa to control them since, to Alexa, they appear to be in an opposite state than they really are. I suspect this might be a weak wireless connectivity issue, since it only seems to happen on certain switches.The other issue is that you have to install an app on your phone that requires yet another account and registration. This is really the worst part about it. I get sick of having to manage yet another set of usernames and passwords for nothing. I have WAY too many accounts already.

I like how easy these are to install. With the QR code I find them to be easy to set up as well. I think these could have a lot of uses. I have two and use them primarily in the winter when we are short on daylight. Before I leave work I can open my app and have the lights on before I get home. It makes it convenient.

Replaces wall switches for lights, allows daily scheduled on and off times, and works on three-way switches without replacing the slave switch.

I’ve also bought the smart dimmer switch and this switch was easy to install and worked in different location with different light fixtures.

Switch doesn't always respond to voice command from Google or the app.

Pure junk would not recommend this switch at all the switches very picky on what type of router it will connect you. I have a high end ASUS gaming router it will not connect at all and I’m using 2.4 to connect it. It will not connect but it will connect to my Netgear nighthawk router so with that being said I would not recommend this because it is very picky on what routers it will connect to.

Home automation particularly anything that connects over wifi is going to for me, require significantly tighter security standards than downloading an app, walking in the door and saying "Alexa" or "hey google."For just this reason I think products like this besides price, are slow getting off the ground. Most homeowners are too smart to purchase a product for their home that was conceived by someone that doesn't even own a home.I did install this device for my kitchen counter lights, it works, but so did the $3.99 original manual switch and all I had to do was lean over and switch it on. If you're desperate to justify that hefty wifi bill go for it. Most homes built since 1970, don't even have "lights." The toggle that this would replace would be an outlet and I challenge you to attenuate 120v with an app, without smoking the outlet. So I approached this carefully, For kicks some people hack their neighbors wifi passwords or de-author their routers. For me this has pretty limited applications. True automation isn't starting the washing machine, true automation is folding the clothes.

Everything worked fine for the first few weeks after I installed this. Then the app stopped working. I reloaded the app and the switch still didn't work. So I (stupidly) took the device off of the app and tried to add it back on. Unfortunately, the app requires that you scan the QR code on the switch, which is now gone, to add the device. Just purchased a replacement, non-Legrand wifi switch.
