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

Replaced and under cabinet kitchen lights switch. Works great and Im was/am really impressed with the easy of installation, both physical and app. Physical installation was simple enough at the switch has your standard two connections (line & load), so that part was easy as it doesnt matter which wire connects to which lead on the switch, which are labeled well on the switch. As I was installing this in a two gang box I had a power plug, next door, which gave me access to a neutral wire, which is required for the smart part of the switch to work. Please make sure you have a neutral wire in the box you are installing the switch in, otherwise it wont work, unless of course you run a new neutral (either from the panel or from a closer location. If you do that please follow your local municipalities electrical practices or high an electrician). The app worked well better than I thought it would, which is a very nice plus. It quickly found the device and within minutes I was able to turn on/off & dim the lights. I opened Google Home (my preference) and added Meross to my home and the switch was there. Ive been testing both the Hey Google and the app incessantly and neither has failed yet, which is very impressive. Overall great product, great integration to my smart home and simple enough installation. Im very pleased.

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 a great upgrade to our old sliding dimmer switch. It works without a problem with the app and Alexa. “Alexa, turn on light” “Alexa, 50% (or whatever % you want) light” “Alexa, turn the light off” It saves the last (dimmer) setting when you turn it off. So if you have it 10% light output then you turned it off, the next time you turn it on it’ll be at 10% light output. -I like that- Installation is pretty straightforward -make sure you have the Meross app and you’re logged in. Make sure the main power switch is turned off!!- the switch wires are well labeled. The app has a step by step guide to get you through. Or if you’re a handy diy-er, you’ll get it installed in less than 5 minutes. If you are starting your smart home project, I highly recommend Meross’ product. They have a lot to get you started and they all work with just one app(!) and all of them (the ones I purchased -garage door opener, smart plugs, smart switch-) works with Alexa.

I installed this switch in my bathroom in about 20 minutes. Note, it does require a neutral wire. Set up is very easy, and the switch does exactly what its supposed to do. One of my recommendations is that the firmware be updated so that when the light switch is off, pushing any of the 3 buttons would turn it on. Right now, the switch only turns on if the bottom button is pressed. For guests that might be fumbling around in the dark for a light switch, they may have some trouble turning this on if they are used to the rocker style switch. My other recommendation is that one of the LED light be illuminated when the switch is of, to aid in finding it in a dark room. My z-wave switches have this option and it can be enabled or disabled. Overall, if youre looking for a single pole smart dimming wifi switch with Alexa and Google control, you cant really go wrong with this item for under $25.

These are very good switches, but understand that this two pack does not contain two complete smart dimmer switches. One is a master and one is a slave switch.

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.

The meross switches I bought/installed are to replace slider style switches that are able to dim LEDs. The LED bulbs in these cases were Phillips Hue. I liked the idea of having Hue bulbs everywhere and I mostly like the Hue bulbs, but after using them for a while I realized we dont use the color and the bulbs just are not all that bright. It also became clear that not having the switches was more trouble than it was worth. Sometimes you really just want to flip the switch and not talk to Google or Alexa. These Hue two lights were connected to LED dimmer switches I had installed, but those crummy switches caused blinking/flickering every now and then. Something had to change. All of that to say, these switches are perfect for us and I will be ordering more. They offer exactly what I was looking for -- the ability to turn the lights on by time or voice, and control them remotely when needed. They are easy to set up, have real on/off and lighter/darker buttons. They look great, but I deducted one star because there doesnt seem to be a way to disable the green and red LED lights on the switch. Another review had mentioned that there may be a firmware upgrade coming for that. If that happens I will update my review. The Meross switches will not dim/brighten the Hue bulbs. Thats ok though, because regular LEDs are -so- -much- -cheaper- and can be much brighter. I never liked that the kitchen wasnt as bright after installing Hue. I can see what Im microwaving now. :)

After latest update the switches are working perfectly. My original review is below. I was super excited by this product and it worked great...for about two weeks. Now the manual switch doesn’t work. I cannot turn the light on or off without my phone. I had a similar problem a couple of days ago and hit the circuit breaker to try and reset the product and that seemed to work for a few days and now I’m back to the manual switch failing again. It’s a bit frustrating. I’m hoping to find a way to update the product in hopes it will correct it he problem or else it will be returned. Original review: I don’t usually get very excited about light switches, but I am about this one. For a couple of years now I have been looking for a decent blue tooth enabled light switch that is dimmable as well as not overly expensive to run my bedroom lights. The switch is by the door and it’s a good distance from my bed, so I have often tripped over a dog toy or slipper while making my way to the bed. If I could only shut the lights off with my phone which is right beside me on my night table? I’ve tried a couple of pricey Bluetooth switches and returned them for not working well. The Meross smart WiFi dimmer switch is everything I wanted. Easy to install, nice looking led’s on the switch, and a very simple app to control the lights with, even when I’m away on vacation. Like many apps I am sure there will be some glitches, but so far I found it very straight forward and easy to use. The install was just as simple since the instructions pop up on your phone and walk you through it one step at a time. My other light switches run a black a white and a green (ground) wire. However after looking closely I noticed that the white wire coming from the switch was actually also connected to the black wire from the wall. Basically that is the break that the switch then opens or closed to allow the power to continue. Behind the switch was the white wire which you need to make this product work correctly. I attached white to white, the two blacks to the now two blacks after I separated them from the switch, and the green to the green. The switch came with wire twist connectors so it was really easy. I then turned the power back on and connected the WiFi and I was done. Less than 10 minutes for me. It’s been working great to date, and my package even came with two switches to make the price per unit even better. I couldn’t be happier.

Update: Downgraded to two stars. I would have gone to one star, but they do still work, eventually. These dimmers dont often respond the first time I ask Alexa to turn them on or off, or to dim them. I often have to ask three or four times. Alexa sometimes complains that they are not responding but most often she just accepts the command then acts like it completed successfully when it didnt. The ones I got look different than the current pictures, so maybe Meross updated them and fixed the problem, but I am replacing them with Kasa anyway. I have many other Kasa dimmers and smart switches and they all work great, so these Meross are going in the trash. :-( ----- I have these integrated with Alexa. I like to have a night light in the main part of the house during the middle of the night. I programmed a routine in Alexa called Good Night that turns the LED lights in the living room down to 5%, turns off the lights in my bedroom, tells me the overnight weather, and starts my sleep sound. Update: I got a new router and it refused to allow me to use certain characters in the password that the old router didnt have a problem with. That meant that I had to change my wifi password and reprogram EVERYTHING in the house. These switches were a real PITA to change the wifi pasword on. I eventually did it, but Im not exactly sure what steps I took to get it done. When youre programming them for the first time, its pretty straightforward. If you have to change the programming for any reason, it is quite a chore. Docking a star for that.

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.
