meross 4 Pack Smart Dimmer Switch Single Pole Supports Apple HomeKit, Alexa Google Assistant & SmartThings, 2.4Ghz WiFi Light Switch for Dimmable LED, Neutral Wire Required, Remote Control Schedule

Great switch, simple install and setup
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.

Not bad
I’ve been using Meross products now for a few years as they are an affordable alternative to Hue and work well with HomeKit. Like all Meross products Ive used, this light switch is very easy to set up.The functionality of the dimmer is just fine. It’s inferior to a regular dimmer because the dimming function is not smooth and requires you to tap the button to dim each level. A slider would be much nicer. It also takes a few seconds for it to respond. However, it does solve a smart lighting issue I had and so it’s fine for now until a better option comes along.

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

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

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.
