Leviton Decora Smart Controller Switch, Wi-Fi 2nd Gen, Neutral Wire Required, Works with My Leviton, Alexa, Google Assistant, Apple Home/Siri, & Wired or Wire-Free 3-Way, D2SCS-1RW, White

Pretty easy to install but is slightly bigger than the existing dumb switches from Leviton. This was to be expected though as the same would be true with any smart switch.I have had this product for roughly 2 weeks now and have had zero issues with WiFi connectivity. Will update if anything changes. The quality of these switches are much better than other brands we have tried in the past and absolutely worth the price.It functions have been extremely reliable as of now and plan to get more in the future. I do wish we would have gotten the dimmable switch but this switch will work for areas that don’t need a dimmable option. We haven’t experienced any flickering of our lights that I have seen in other reviews.

Easy to install, replaced an older rotary knob ceiling fan switch 1.5A.I didn’t use the enclosed decora plate as I installed in a 3-gang box with a 3 gang switch plate. Also Comes with an ivory colored switch cover but only a white single gang decora plate.Has separate English and Spanish instruction sheets which makes it very easy to work with. I do not like those sheets that put all the languages in paragraphs right next to each other in same document.I integrated it with the Amazon smart speaker system (Alexa) so I had to go into the Alexa app, then go to skills then search for the skill “My Leviton”. Once enabled the ceiling fan came up as a new device. I can now control it with my voice.Choice are Max, high, medium, low, off.

I have these all over my house, great for lazy Alexa commands, I set timers on lights to turn off the ones my wife can’t manage to find when she is done with it.Also great for my outdoor lights to shut off at a specified time.I even have one managing a relay for my 220v air compressor, it turns it off at 10pm every night because I forget. Also I can be in my shop and yell for Alexa to turn on the air compressor.

You need Android 12 or higher on your phone/tablet to use with Alexa. The dimmer plug seems to work fine, only have a few days use so far though. A problem people should be aware of is, it says you need android 8 or higher to use their app. Amazon says you need android 9 or higher to use the Alexa app. BUT went you go to link accounts the Alexa app says you need android 12 or higher to link accounts. Which means you can't use it with Alexa if you don't have 12 or higher. My 89 year old mother's phone has 11 and it can't be updated higher. I didn't want to sign out of the Alexa app with my phone because my entire house is smart and I didn't want to risk losing my setup. Finally I got my bothers phone to use (he doesn't have smart devices) and used his phone to link the accounts. But it was a pain to figure out what needed to be done and getting it done. Just a Warning for anyone that doesn't have android 12 or higher.

Best light switch i have ever put in my home. The instructions are easy to go through and installation takes no time with a screw driver and wire cutters. All my lights are on this timer with the app and its easy to control and connect. Makes it look like you are always there and still functions as a normal switch if needed. Highly recommend for outside lights

A review is sometimes only as good as the experience of the person who is leaving it. For this reason, I often ignore some reviews and give much more weight to others. I will begin by saying that I have over 20 years experience as a computer technician and have a family full of people who work in trades (plumbing, heating, air conditioning, and electric) so my home network and my electrical system are in solid working order. I have a wireless mesh network blanketing my property and there are no dead spots anywhere in my house. Here is my review of this item:(1) Ergonomics. Unlike other switches, this Leviton switch is a completely smooth, flat, featureless plastic surface. It is impossible to reliably locate the on button in complete darkness - it is exactly the same as the off button. While you can talk to it (and that has its own issues), the buttons should be easy to locate with your eyes closed and should be slightly illuminated so that you can see it but not be annoyed by it.(2) Connectivity. As you will see in other reviews dating back to 2017, the devices bings and bongs, bleeps and beeps, randomly and annoyingly throughout the day and night. It disconnects from the internet whenever it feels like it. My wireless access points are not more than 20 feet away and not one of my 4 Leviton switches can maintain a solid connection. The Tp-Link Kasa switch that is directly next to it has zero connectivity issues, and all my mobile devices have no issues with the home wifi. Leviton's response to my email is that the wifi is getting affected by the fact that it is installed in a metal box with a metal cover. "Unfortunately, for wireless in-wall devices, metal wall boxes or metal wall plates typically attenuate the signal, so even if connected, it could be intermittent. While we recognize that it is difficult to change a metal wall box, if you can, we recommend using Leviton Decora wall plates." If this is true, then why aren't the competitors' smart switches affected by the metal? As you can see in my photo, the Tp-Link Kasa switch is right next to the Leviton switch and has never had any connectivity issues.(3) Lighting Performance. To dim or brighten the lights, you must hold down the power on or off buttons. It makes the job very imprecise. In addition, every Leviton switch produces an audible hum over the internal speaker whenever the dimmer is used (I have halogen as well as LED bulb fixtures and it happens on all of them). Maybe because it is so compact, Leviton needs to shield the internal speaker from the feedback of the dimmer. I do not know why it happens but it happens on all four of mine.(4) Smart Home Performance. Occasionally, I will tell Alexa to turn on the lights, she will say "OK", and nothing will happen. I tell her to turn them off, she says "OK", and nothing happens. I then have to completely reset the switch and join it to my Alexa network. I have never had to do this with my Alexa Echo or my cheaper switches from Leviton's competitors. Other times, I will send it a voice command and it will stutter and lock up. When I try to use the switch to "drop in" on another Alexa device, it completely locks up the device and says "Calling with Alexa is not supp...Calling with Alexa is not supp...Calling with Alexa is not supp..." in a loop. Leviton says it is a known bug. Leviton has now informed me that using the switch to make a call is not supported, even though it has both a mic and a speaker and is connected to Alexa. Um... why not?Bottom LineIf you expect this to be an Alexa Echo inside your wall, it is not and it probably never will be. If you expect it to do its job as a dimmable light switch, it will do a poor job of it when compared to switches that are a quarter of the price. If Amazon is your smart home platform of choice, buy an Alexa Echo for half the price of this switch and you will get all the features along with some decent quality speakers. Then, buy your remaining switches from Tp-Link Kasa (pictured in the photo) or another capable manufacturer to round out your smart home purchase. I had high hopes for these switches but they are all being returned after 2 months of struggling to make them work.

I've had trouble getting other brands of wifi witches to pair with my dual band router. Most of those are 2.4 GHz and don't want to pair with with my 2.4GHz/5GHz router. I have returned items because they wouldn't pair. I saw a YouTube video about installing wifi switches and the guy said he had no pairing problems with Leviton wifi switches at 2.4GHz. He was right. I installed it and in less than five minutes it was paired and working. To reduce a lot of frustration I highly recommend the Leviton wifi switches.

Absolutely 5 star, easy to install, great functionality and using the companion switch can be controlled remotely.
