meross Smart Dimmer Switch Single Pole, Neutral Wire Required, APP Control

I have bought many of these and nearly the entire house now uses Meross switches for lighting. These are relatively simple to install. You absolutely must have a neutral wire in any switch box in the wall in order to use these. While a neutral wire (typically white) is present in most switch boxes, one might not be present in older homes (built before 1985 or so). These will fit in a standard sized switch box, but if you have an unusually shallow switch box, they won't fit. The installations instructions are quite clear, and several videos available showing how to install this, some by Meross, and some by others. After installation, initially the device is connected to and controlled by the Meross app. It is very easy to connect the device to the Meross app by following the instructions in the app. Once you have connected it to the Meross app, you can follow instruction in the Meross app to integrate the device into Alexa. If you have already connected the Meross app to Alexa for previous Meross devices, the new device will immediately work with Alexa. You can even remove the Meross app from your mobile device and Alexa will still properly control the switch and other Meross devices. (This also works with Apple Homekit, but I have not used that and so I can't speak to that.) The switch and dimmer buttons work perfectly with my LED lighs. The dimmer requires some slight additional setup in the Meross app. The tactile click of the switch and the dimmer buttons is a major plus. I used to use a more expensive brand that did not have the click and I found it very annoying. Up to maybe twice a year, one of the switches seems to lose track of whether it is on or off. For example, if the light is off and I say "Alexa, turn on office light", Alexa responds, but the lights don't turn on. This is because the switch seems to think the lights are already on. To fix it, I just say "Alexa, turn off office light", followed by "Alexa, turn on office light". Then the lights turn on properly. Please note: some people will tell you that in lieu of a neutral wire, you can just use the ground wire. DO NOT USE GROUND IN LIEU OF A NEUTRAL. If you don't have a neutral wire in the switch box, have an electrician run one in the wall from the nearest outlet. No current should be flowing through your house ground. That could lead to electrical shocks or even a fire, and it is not legal. Pros: 1. Clear installation and setup instructions (including numerous videos available) 2. Nice tactile click when you press the switch or dimmer buttons. 3. Excellent quality - I have installed about 25 of these and every one worked right away and all are still functioning fine up to three years after install. 4. No hub needed when using with Alexa. 5. Much less expensive compared to other brands but device appears solidly made. 6. Comes with a fancy screwless cover plate for a smooth look. Cons: 1. Very rarely switch seems to lose track of its status, but easily fixed. 2. Cannot be installed in an unusually shallow switch box. 3. Requires a neutral wire which may not be available in older home switch boxes. I obviously recommend this switch as I keep buying more to add to the home.

I have been working with smart home stuff for awhile now and have not been extremely satisfied with much of it. I had another 'smart' dimmer wall switch before that was too 'fussy' and would work sometimes and not others. I am an Apple guy, but haven't been largely satisfied with stuff supposedly Apple compatible. I purchased the Meross switch knowing it was not compatible with Apple, but it is wonderfully compatible with my Amazon Echo (Alexa). I have been using this switch for sometime now and can say unequivocally that, in conjunction with my Alexa, it has been flawless. It just works! When I have visitors like my daughter, her husband or my girl friend who visit and are not familiar with vocal commands, the Meross can be operated manually with the little tap control at the top of the switch that varies brightness. As it happens this switch is used to control the chandelier over my dining room table and it is wonderful. As the dining mood changes, I can say "Alexa dim dining room to 35% or set dining room to 100% brightness". Installation requires connecting the neutral wire to the switch (as to many others) as well as the ground and the 'hot' side. This could present an issue in a tightly wired, small box, but the installation is straightforward. Again what I love most about this switch is that it is so reliable. I have never had it go offline or need to be reset. it is quite trustworthy and, as I said, fully compatible with the Amazon Echo.

Love Meross and their products. They've been rock solid for me over the last couple years. However, they always provide mounting screws with a really odd non-standard thread pitch of 42 threads per inch. There is no such thing as that size for electrical devices in the US! My photo shows a standard 6-32 screw on top with the two 6-42 screws underneath that came with this switch. In the US, electrical devices are mounted with #6 screws with 32 threads per inch, 32 thread pitch, aka 6-32. The Meross screws measure the exact same diameter as a #6 screw but they have 42 threads per inch. I am sure you could force these screws into the box holes but I doubt they will come back out. You will also have destroyed the 6-32 hole in the electrical box thereby making for a really bad day if/when you try to re-install a standard switch with a 6-32 screw. My strong recommendation would be to save and re-use the original 6-32 screws from your old switch. EDIT: Once per day switch stops responding! Clicking physical switch on wall does nothing. After hitting the reset button, it starts working within seconds. The reset is not a big deal except that if I am trying to control the switch via automation, it appears to be responding while it is physically doing nothing. This is unacceptable and I have sent a message to tech support. I may exchange via Amazon to see if a new one is better. I also noticed that it was reporting a wifi signal of only 26%, but then after hitting the device reset button, wifi signal jumped up to 99%. I am assuming something is very wrong with the wifi radio on the device. EDIT: Tech support is going to replace it.

Stunning. I've purchased Meross products in the past, but this switch takes it to the next level. It looks like a premium switch without the premium price. Very high quality, easy to set up and looks amazing. The dimmer buttons are perfectly placed so you can easily turn the light on and off, and the light comes on at the last dimmer brightness setting. Their app allows for effortless setup, routines, and integrates with Google home, Apple and Amazon Alexa seemlessly. Customer service is quick to respond and resolve any issues that arise. This is an incredible value.

I had ordered this dimmer switch to work with 4 led recessed ceiling lights and faced all types of issues. Pros: Cheap price Easy to install (like most other switches) Cons: Clunky design: Personally I never found the design very appealing and modern. But it’s only after one holds the product, does one realize the clunky tactile response of the switch. Unresponsive hardware: The dimmer function would not kick in until I had physically clicked more than 50% down. I had four 18W led ceiling lights. When I changed this switch with Wemo, the response was much better. Unpredictable software: The dimmer response was much better with the app and HomeKit. However, strangely the leds were notably brighter at 15% than 25%. This only happened around those %-levels. No support: Since the company is based in China, there is no phone support. You need to raise a ticket and the process is quite cumbersome. I tried rewiring and reinstalling app couple of times. But it didn’t alleviate above issues. So, I requested a replacement, which solved the issue I was facing when dimming using phone. But the hardware response continued to be poor. Even though the idea of smart switch is to be able to use it over the phone, it doesn’t make using the actual switch physically any less significant, at least in my case. So, I ended up returning it.

I was originally looking at Lutron Casetas, but given the price and the number of switches I had to do, I decided to give these a try. The install is as easy as any other switch as long as you have a neutral wire. Pairing with HomeKit was also easy, just ensure to use your 2.4ghz network, it does not work with 5ghz. Very occasionally, I’ll notice the switch is blinking orange and needs to reconnect. Most of the time it will fix itself, but I usually press the small button underneath to reconnect. A very small trade off and hasn’t caused any major inconveniences

I have tried a few HomeKit switches and dimmer most of which had many problems and always left me unsatisfied. This one is different. Installation was easy with the included directions. The design is good and fit well in the cover plate the original dimmer, as seen in the picture. Initially, It would not connect to HomeKit and reported the dreaded "no response". Deleting and trying again everything worked. The function of the dimmer is nice. There is an On/Off switch on the bottom and the dimmer level is retained between switching. The response with either hardware buttons or HomeKit is good without the delay of some of the ones I have tried. I am going to buy another switch to replace the other dimmer in the picture. That is a good endorsement.

This a good switch if you are looking for an affordable HomeKit option to start your smart home set up. Installing was fairy simple, not too difficult. Linking it up to my wifi was a bit challenging at first using the app but I figured out I can link it up to my wifi faster and more effectively directly from Settings > Wi-Fi. It will show up in there and when you click on it, it will take you through the set up to link to wifi and then once it is set up in there you can wrap it up in the app and connect it to HomeKit with the code. Once I figured this out I was able to run through the set up quickly with the others I bought. Adding it to Alexa is also a breeze and it works great for that as well. The product itself is fine but does feel a little plasticky if that makes sense, but it still seems good. The features in the app itself are not that great and very basic and I only have the app for the set up process and never use it for anything. I use HomeKit exclusively to manage my light and switches and occasionally I shout a command to Alexa, which like I mentioned before, both works great. HomeKit recognizes it and functions well with it as well as Alexa. My one complaint about this dimmer is the lack of customization to the dimmer buttons. They are preset to dim at 75%, 50%, and 25% and then off. Personally on my light bulbs this does not really work that great and doesn't seem like it really dims that well. I don't know if this is the light bulb or the dimmer switch itself. I can dim it in HomeKit and it works great and I can get it as low as 1% with just barely enough light to light the room. But the buttons on the switch are not great. I had purchased TP-Link Kasa prior to Meross and really liked their switches and the app. The buttons on the switch were customizable in the app to the specific setting you wanted it to be. So I really like that option. I returned those because I wanted HomeKit functionality. The switch and app on the Meross is very basic and not customizable as other smart switches which is a bit disappointing but something I can live with since it is an affordable HomeKit option. I have had this dimmer switch installed a little over 30 days and I have installed 5 of these dimmers. Yesterday one of my dimmers stopped responding in the app. I tried everything to get working again, resetting, rebooting, pushing any and all buttons and nothing worked. I turned off the breaker to see if that would reset but nothing. It won't come back on and all lights on the switch are off. The thing is broken and just right after the return date! Not happy about that at all! These are affordable, but if they can't even last 30 days that is very concerning. I now have to go to Meross directly to get a replacement and I'm not too happy about that. We will see how that goes. I am hoping this is a fluke and I just got a dud and that my other switches don't follow suite and start crapping out on me as well. I'm giving this 3 stars due to one of my switches has already died. Before I would have given a 4 star based on the basic functions of the switch and app and affordability and it being HomeKit. If I can get my broken switch resolved quickly and painlessly with Meross I will give it a 4 star review.

supero mis expectativas , producto muy bueno que opera con siri y funciona muy bien, solo al principio batalle para instalarlo porque esta mas enfocada a android

This dimmer was easy to install, and works well with Apple HomeKit. The dimmer function works flawlessly (unlike the 3-way version). However, there is one desirable feature (to me anyway) missing - that is one of the device settings - LED - can only be enabled, or disabled. There is no "night light mode" choice which is available on the 3-way dimmer MSS570x and 2-way smart switch MSS510x. I hope this missing feature will be added via firmware update later on. [UPDATE] I contacted tech support and they confirmed that there is a new firmware version to provide the night light mode setting but just not yet released but they would push it to my switch to enable it. I revised my overall rating from 4 to 5 stars.

Funcionó de manera excelente, fue muy fácil configurar con HomeKit y no tiene desconexiones. Excelente producto

Made a choice to use Alexa, but after 11 months Amazon delayed to fix issue and indicated my Echodot mini 4th gen not connections to Wi-Fi would require replacement but warranty was over. Bought Apple HomePod mini, discovered Gosund were not compatible with Apple. So choose Meross as replacement. Works better, setup done 1st time, never loosing wifi connection. Unfortunately, scanning QR code from AppleHome allocation does not work with this switch. I had to enter the 8!digits number manually. Besides that very impressed, so much easier that previous switch to install and reliability flawless so far! Note: not sure why you have products Google/Alexa compatible only and other Apple HomeKit/Google/Alexa. Found this annoying when ordering and it's not always clearly indicated. AMAZON SEARCH, does not filter well Apple HomeKit product.

El dispositivo funciona perfectamente segun lo indicado, tiene buen precio en relacion a productos similares. La unica razon por la que no le doy 5 estrellas es por algo que es muy especifico de algo que me hubiese gustado tuviese pero no parece tenerlo. Si esto no es importante para ti el dispositivo vale las 5 estrellas. Pros: - Me gusta que los botones son fisicos y dan retroalimentacion de haberlos presionado, comparado con otras marcas/modelos donde es touch y no se tiene ese sentimiento de interruptor tradicional. - Funciona como atenuador desde 1 hasta 100% de luz mediante el uso de la app. - El conectar el dispositivo a la app es muy sencillo asi como vincularlo con google home. - Contras: - Mi mayo conflicto es que los niveles de atenuacion son fijos. Es decir solo se puede 5 niveles predeterminados de atenuacion mediante los botones, y el nivel mas bajo no es el minimo que se puede obtener. En la app como se mencionaba antes puedes configurar hasta 1% nivel de luz, sin embargo en los botones andara como en el 10-20%. Al configurar la app por primera vez parece que uno puede configurar ese rango, pero almenos en mi caso no parecio fijarse de forma permanente. Pero repito uno puede configurar a minimo en la app o por comando de voz (2% en Google home, por algun motivo en home solo deja al 2%, pero directo en la app se puede el 1%) Esta limitacion probablemente no le importe a muchos y en lo personal tampoco me afecta demasiado y entiendo el porque el dispositivo funciona de esta manera. Lo ideal seria se pudiera configurar el numero de niveles de atenuacion y el minimo y maximo nivel de luz para los botones fisicos. - La segunda contra, que no es como tal critica pero que DEBEN tener en cuenta quien sea que compre el dispositivo. Es que el interruptor REQUIERE el cable neutro. Y es importante conectar los cables correctamente. Si el interrupor en tu hogar esta colocado en el lado neutro del circuito (es decir el interruptor corta el circuito después del foco) el interrupotr no funcionara. Se necesitara que re-conectes la instalacion electrica del foco para que pases el interruptor al lado "vivo". Este fue mi caso, y requer[i hacer ajustes en el registro del foco cambiando el flujo de corriente para poner el interruptor antes del foco. No es muy complicado de hacer, pero para una persona que no le sepa o no tenga la paciencia para moverle al cableado y aprender de electricidad recomendaria que se la piense dos veces antes de comprarlo a menos que este dispuesto a contratar a algun electricista que se lo instale en caso de que no funcione facilmente al querer hacerlo usted mismo.
