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

Update: I discovered a fix. To dim to more acceptable levels, use the app. Select the switch, then pull down the menu, upper right, 3 bars. Select compatibility test, press start testing, a graphic bar will appear, and brightness is set at 40%. Lower the brightness to 1%. Then exit. This should be your new default when you next lower the brightness level, either manually or when using Alexa. Not perfect, but much better than the default level of 40%. I am a fan of Meross switches, I have 2 that we have been testing and they have been very reliable. I cant say the same for the dimmers. The main issue is the range of dimming. We began having several installed but stopped after the problem became obvious with the single pole dimmer. It was installed in the master bedroom and has been a major disappointment. The range of the dimmer is pretty much useless, as it will not go below about 50% brightness. There is no firmware fix, or one planned. So we will reluctantly look for alternatives.

I was pleasantly surprised that this was indeed a kit to re-wire and control both ends of a 3 way switch setup! My biggest complaint has been mis-matching switches on either end and this resolves that and both switches act as one. Actually works better than typical mechanical 3 way switches where one switch will end up opposite of the other. You toggle either switch and they communicate and will always be in the same state. And with the added smart functionality you only add one switch since they act as a single unit! Meross has been bringing a lot of great new smart products and this one really sets the bar high. As far as installation goes they have improved the wire leads by soldering them, no more need to twist the wires prior to putting on the wire nuts. Included instructions were easy to understand and within 10 minutes I had both switches replaced and full functional. I set these up to control my kitchen LED lighting which I wasn’t even sure were dim-able but after testing they work perfectly! Each level of brightness is a clear change and absolutely no light pulsing. As well the switch will remember the last brightness level after being toggled off and back on. I set these up with HomeKit as well they popped right into my Alexa app since I already had the Meross skill setup, so no user intervention there. I have been using them for about a week now and have 0 issues. I would highly recommend these to anyone wanting to setup 3 way smart switches. Now I hope they release regular non-dimmable 3 way switch kits.

Package comes with 2 switches. I used the Meross app to add the dimmer switch and added it to Apple Homekit without any issues.The app has a lot of really nice features including setting the minimum brightness so your lights always come on when power is turned on. I have been using them for about 10 days now and have no issues. I would definitely recommend this product to anyone wanting to setup 3 way smart switches.

These can be a little tricky to install - in my case - the master and slave had to be installed in a certain location and they wouldnt work in the other location. From the wiring alone - you couldnt tell which location was which so It took some troubleshooting to figure out how to get it setup correctly. Once setup though - i have found the Homekit integration rock solid. It hasnt dropped or shown offline and it has worked quickly every time i have opened up my phone and tried it. I also have the Meross garage door opener and having tried several smart products i feel like Meross makes some of the best ones.

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 the second meross product Ive bought (first was the garage door opener which also works well). It was easy to install. If you can install a standard light switch then this is not too much different. The meross app found the switch with no problem and completed the setup. The app works inside the home and when Im away. I like the look of the product. Its simple compared with some of the smart switches out there. It comes with a single gang face plate. If you were installing it in a multi-gang box, youd need to order your own face plate. Have a look at some of the customer images for examples.

Item is built very well. I had issues with their single pole switches from about a year ago where they had dead spots on the physical button, but these switches do not appear to have that problem at all! Very well built, install was super easy, and they worked with my Phillips bulbs I got from Home Depot for other parts of the house. Homekit pairing and integration was perfect on the first try as well on my Eero mesh system. The only suggestion/wish list item I have is for the dim and increase buttons to have a different feeling. Maybe the increase has a bubble feel and the dimmer have the recessed feel just to make it easier in the dark to know which one youre hitting instead of having to feel up and down to see which one youre hitting.

Works perfectly with Alexa and my existing dimmable LED lightbulbs. Installation instructions were very clear. Unfortunately, my fixtures were wired differently (two traveller wires and live rather than two traveller and neutral in box with dimmer). Luckily, I was able to change this relatively easily and the lights work well with this dimmer. One difficulty with all these smart switches is that they occupy more space in the box, and the neutral wire cap also occupies additional volume. You need to be very aggressive about folding the wires back in the box for it to fit.

I have decided to use only Meross products for my home automation project. They all are of high quality, easy to install and work trouble-free. The company’s customer service is great. Prompt replies and eager to solve any problem. I strongly recommend this company.
