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

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 :(

I already own multiple Meross products. When I saw they had a HomeKit 3 way switch, I had to buy it. Great product from the start, inside the packaging there’s labels for each wire, clear instructions if you are unsure what you’re doing. Setup was easy with HomeKit, super reliable and no issues with setup. Highly recommend!!

It was a bit trickier than expected to get this 3 way dimmer installed,mainly because of all the plain black wiring in my house and my inexperience wiring, but I had this put in by a pro and it works great!. Easily one of the most reliable HomeKit switches I have used, which is especially amazing as its a wifi one. Ive yet to see this fall off the HomeKit network or give me any problems. it always just works rock solid from both sides. I set this into multiple home automations and it works excellent every single time. So nice to be able to control my lights from both switches and remote and have dimming function all from this surprisingly affordable 3 way dimmer. I highly recommend thi switch, and meross in general, to anyone starting out in the HomeKit ecosystem. Great value for the money and all of their devices seem to work without a problem, unlike many competing brands!

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.

This is my 2nd set of 3 way switches from Meross. Had an electrician do the install because Im just too unfamiliar with the 3 way configuration. After he was done with the install, he was impressed with the switches so much, he ended up buying a set for his house. The Meross app is incredibly easy to use and navigate through. Highly recommend.

I was really excited to get these because of all of the great reviews. Unfortunately, I am disappointed with my purchase. I just installed one of these switches and immediately noticed that the minimum dim level is not nearly as dim as my lutron dimmer. I enjoy having very dim lights while watching TV at night so I can still see my surroundings, but also not blind me and glare on the TV. My picture shows the comparison of the Lutron dimmer (left) and the Meross dimmer (right) both set to their minimum levels. The lights are exactly the same so this is strictly the dimmer causing the difference. Excuse my mess, I am in the middle of a remodel. I will likely be returning these switches because the minimum dim level is very important to me. I still left 4 stars because everything else worked very well. Google integration was easy, installation was easy, and the Meross app was very easy to use.

These 3-way dimmers with HomeKit support were the final piece to my HomeKit lighting puzzle! With these installed, now all of the lights in my house dim from 1% to 100%, all through the Meross app, and Apple’s native Home app. Installation couldn’t have been easier (you can do it through the Meross app and/or Home app - your choice!), and you won’t find a better price for HomeKit light switches. Oh, and there’s no hub required!

I needed a smart dimmer for a 3-way switch in my hallway. This unit fit the bill on two fronts, first being a Merross product as I had several others installed already and second being able to control the light using an Alexa Routine. Installation is pretty straightforward once you identify the wiring correctly and get get the main and secondary switches wired in. Not as many dimmer options using the switch, but from the app and Alexa you have the ability to be more granular with brightness levels for the fixture.

The first switch set I received ended up being defective. Meross was very responsive and after a couple of emails, I promptly had a replacement, which worked as it should. I have several of the Meross smart switches and this is my first one that is a dimmer. I love all of them and will likely purchase more as I continue to make the switch to a smart home.
