Smart Dimmer Switch Single Pole, Meross Smart 2.4GHz WiFi Light Switch for Dimmable LED, Compatible with Alexa Google Assistant and SmartThings, Neutral Wire Required, Remote Control Schedule,1 Pack

The installation, wifi, HomeKit and Alexa integration is outstanding BUT there is NO FADE. That means dimming is jittery and stepped. There are no other reasonably priced price Homekit 3 way dimmers and so I’m stuck with this until someone else comes out with it.

I have seen other 3 way kits but none that provide dimming function on both the switches. Works great with all the smart home solutions out there. It took a while to get it working but that was because my home wiring was not what I expected it to be. You have to install these exactly as described or else it wont work.

I put these in my kitchen on six LED can lights and it works great. I also install one in each bedroom for the kids and myself. They are easy to install with instruction right on the app. The switches work really well with Google Home. I can tell Google what level to put the lights to and it instantly does it. You can even program times for the lights to turn on and off. For the kids rooms I programmed the lights to turn off at 10 pm to let them know its time for bed (if by chance they hadnt turned them off by then). I put these and the single-pole switches all throughout the house now I just need to install the three-way switches to finish up all the light.

I bought these smart switches to control lights in my home. Most of the smart switches went to outdoor lights as it was the best option for me to have the best control of lights I needed to operated remotely. The install is super easy and they connect to my wifi with no issues. Every one that I have installed needed a firmware update immediately after installing but they were operational in minutes. Pairing with Alexa app was also easy and I was turing on and off my lights using my echo dot in minutes after install. They are a little bulky compared to normal switches so make sure you push the wires and wire nuts to the far back of the box you are installing them in or you wont fit them in on the first shot evenly. They do need to be grounded and I had to ground them to a metal electrical box in one installation as I have some older wiring in my home along with some newer but the switches work great and wifi signal is not an issue in plastic or metal boxes. I also love that when the lights are off you see a little red light in the body of the switch. You can instantly tell if the lights are on or off and if it is dark in the room you can easily find the switches. They also make a satisfying click when depressed and I havent had a single issue with any of the switches that I’ve got.

I have installed several Meross switch products with HomeKit compatibility, and am overall happier with these switches than others that I have tried (mainly from Lutron and Leviton). Given the overall favorable reviews, I thought I would identify several issues that buyers should be aware of before moving forward. I like the Meross products, so I hope they expand and improve their product line. First, Meross provides the wrong size/thread screws for mounting their switches to US junction boxes. They should be 6-32 machine screws but they are not. OK, no big deal, so I used the screws that are already on my switches. Well, those have round (instead of flat) heads. They bulge out just enough that it is essentially impossible to get the snap-on switch plate attached. There are reviews on this or other Meross switches that complain of the same problem with the covers, but they dont identify that this is the problem. Second, the leads are permanently attached to the switch box. I would much prefer screw or push-in terminals. Every Meross switch has at least four leads, which increases the number of ends in a junction box. I am certainly not an expert on the National Electric Code, but I do know that there are limits of how many wires can be in a junction box with a given volume. Two-gang switch boxes become very, very crowded when replacing both switches with smart switches, especially when there are other wires traveling through the same box. Third, the switch housings are very bulky. This is true of other smart switches as well. I ran into a problem where a two-gang junction box has conduit coming in from the side. The switch is so wide that it hits the side conduit fitting and could not be inserted. My solution was to file down a small part of the plastic housing on the switch so that it could fit. (I did not file all the way through, which is how thick the plastic housing is. Of course this means that it is a durable housing.) Fourth, where we live, conduit and grounded junction boxes are required. The Meross switches should be grounded at the plastic tabs so that we dont have to bother with the ground wire. Unfortunately, they are not. Finally, if you want to adjust the minimum dimming level of a dimmer switch, or check for firmware updates, you MUST sign up for a Meross account, which I dont like. The Leviton switches that we have do not require this. Minimum dimming levels and firmware updates can be done through the Decora Smart Home app without needing to set up an account.

This is the third Meross HomeKit light switch weve installed now. Over the course of 6 months or so weve had no hiccups with any of them. The more lights we put on HomeKit the cooler the scenes can be. We wanted the recessed lights in the kitchen to be just barely on while watching a movie so that people could grab snacks without flipping on lights. So we put the recessed lights on our new 3 way dimmer switch and set up a HomeKit scene for movie nights to turn them to 1%. Even at 1% there is no flicker. We also added a scene for washing dishes which turns the recessed lights up to full brightness so we can see that everything is getting clean. As far as insights about the switches themselves, the buttons have a nice click to them. They are a very bright white. The switch plates in the photos are your standard Leviton white plastic plates. The Meross switches definitely stand out a bit, but the photos exaggerate the difference slightly. The instructions Meross provides for installation are always great. I did myself a favor this time and bought a voltage detector to help identify wires. Its a worthwhile investment in convenience and safety if youre going to be replacing switches.

this comes in pair and if you have a new set up where ur exact need is not a pair of new smart swiches, do not buy. the logic behind these switches r different from normal dumb 3 way switches i tried to replace the main (one that draws line voltage) and only dimmer in 4 way (3 switches) set up. it works in adjusting and turning on off but my other 2 dumb switches stop working. i selected this because of homekit capability and because i have other meross switches. very disappointed i ended up with another brand of smart 3 way dimmer and have to suffer the indignity of using alexa :(

Including: • turns your lights on and off. Check • dims your lights. Check • undims your lights. Check • works with Alexa. Check, although whether Alexa works is a different story. The only way I could get it to work in my daughters room is if I changed her name to Brian. • works with Google. Check. Although running back and forth to Vital Statistics to change my daughters name to Brian and back again depending on which smart device I want to use is going to be a real pain. • easy to install. Well, yeah, pretty much. The instructions (which, by the way, are printed on the box—dont waste your time hunting around the house to see if you dropped them, like I heard some people did) simply say to use the Meross app. Which is a lot more useful than youd think. About eight screens worth of clear diagrams. The most important ones have been reposted in these reviews. If youve spliced wires together before using wire nuts (included), installation is pretty easy, once you understand what all the pictures are of. (I thought the switch was an iPhone for a long while.) There is only one diagram you really need, the one that shows how to connect the four switch wires to the four colors of wires in your junction box. The only trouble I had with installation was this step…the diagram tells you to hook one of the switch wires to a wire that will be either black or red, another to a wire that will be either black or brown. Well, the wires in my house are bare copper, white, black and…black. So two black wires, both coming from the same direction in the junction box, no red, no brown. So I just shrugged and picked a black wire at random, pretty sure (OK, hoping) that it wouldnt matter too much if I got it wrong (by the way, I dont think this is a common practice with actual electricians). Of course with 50-50 odds I lost. The switch did nothing. But, no sparks came shooting out of the wall toward my eyes, so I was heartened enough to take the switch back out, switch the black wires, and try again. And then everything was fine. The switch gave me a quick little light show to let me know it was working and to show off a bit, frankly, and that was that. If not for the two-black-wires snag, the installation wouldve taken about ten minutes or so. Thats not including adding the device in the app. Which was also pretty easy, but as I had bought a few Meross Wi-Fi outlet switches before, I already had the app, so it was just a matter of telling the app I was adding a new dimmer switch, and that was basically that. I didnt have to type in the Wi-Fi password again or anything. Basically my phone pointed double fingers at me and said, Gotcha covered. (This actually happened.) Then I had to go to Google and Alexa and add the devices there. That was also really quick and painless. Until, as I mentioned, I tried to get Alexa to understand my kids name, so if youre trying to decide between Google and Alexa, advantage: Google. Sorry, Amazon. :-S • You do need to have a neutral wire. Now me not being an electrician at all (maybe you could tell?), this was very confusing to me. In my wall Ive got sheaths that each contain a wire, and another wire, and a naked metal wire. I assume ones hot, ones cold, ones ground. I think but I wouldnt swear that blacks hot, whites not, and Im almost positive that bare copper is ground. But I dont know if any of them are neutral or not. And I dont know how to tell; they all seem nice enough. And the fact that Meross thinks I should be finding red or brown wires in my walls makes me wonder if I should trust their judgment. But this is the Age of Readily Available but Highly Questionable Information on the Internet. From what I found out, if you have a house built after 1980 or so, youve most likely got neutral wires in your wiring. Which wire? The white one. Whats the difference between it and a not-hot wire? I dont know. But basically, if you open up your junction box and it looks like the picture on the Meross app, youre good to go. And to be extra safe, I described my setup to Meross, and they wrote me back very quickly and assured me that I had what I needed to make the switch work. So I took a deep breath and went ahead and connected it (again, not how electricians do it), figuring if the switch didnt work out and my house burned down, well, thats a scathing one-star review for Meross. • it does remember the setting you last set it at, contrary to what another reviewer said. If you set it to half-bright on the wall, when you turn the light off and back on it comes up half-bright. Whats more, if you open Google or Alexa, they both show the light as half-bright. If you tell the Google app to turn the brightness to 20% and open the Alexa app, you will see the brightness is at 20% there too. And vice versa. So I had no troubles with the switch losing its memory. • the switch fit my junction box, no troubles there. The switch plate is pretty flush to the wall…maybe I wouldve liked it a smidge closer, but I dont think anyone but me would ever notice. But its not like its uneven or anything. The plate snaps onto the switch rather than screwing on, which is a bit clunky. • I had no delay in turning on the light. Unless you count the light quickly ramping up from dim to full brightness; it starts out dim and very quickly brightens to full in less than a second. I thought that was kinda cool, a feature, not a bug. • the light on the switch is bright enough to see and help you find the switch in the dark (if you cant remember that its where it always is, by the door), but its not bright enough to keep you awake, in my opinion. When its dark in the room, the bottom light glows a pale orangey-red. I have had devices with LEDs so bright I had to break out the electrical tape, but this is a subtle glow and wouldnt bother me. I do wish that the Meross app allowed you to do things like cut off the LEDs altogether, just because some people would prefer that, and why not allow you to? It couldnt be difficult to code that option in. Or change the maximum brightness level; you can change the maximum dimness, why not the maximum brightness too? Most people wouldnt care, but its an easy feature to add for those that would. • I fail to see why using wire nuts in wiring a switch is a problem. Thats how you do it, isnt it? (Again, not an electrician.) CONCLUSION: I would give it four and a half stars, but since I cant, and since the reasons for my half-star penalty wouldve been quibbly, five stars. Does what it says it does, works, not hard to install. Ill edit my review down if I have any trouble with it. Full disclosure: I received this switch for free in exchange for giving a review of it, but I didn’t go easy on them for that. They just asked for a review, period, not a favorable or five-star review. I just gave the switch that rating cz thats what I think it deserves.

Yet to try with Alexa

Works well, and pairing was fairly easy, but very limited dimming brightness range. Instead of having a brightness range from like 1 - 100 its more like 50-100. Even fully dimmed, they are not really dimmed much. I have other brands of smart dimmers that dim fully, but this was the only 3 way smart dimmer I could find that works with homekit. The other negative of these is that they dont come with the homekit scan QR code. They have the homekit number on the front of them so if you manually enter it, and it works fine, but it would be nice if they included the QR code to make it easier.
