3 Way Smart Switch, Meross Smart Light Switch Supports Apple HomeKit, Siri, Alexa, Google Assistant & SmartThings, 2.4Ghz WiFi Light Switch Neutral Wire Required, Remote Control Timer 2 Pack

To start with, I am very happy with my purchase thus far. It was priced right, easy to install (took about 5-10 min), and works very consistently. I have started to get more into smart devices recently, and had a problem I needed to solve. I own a 3-story townhome, with a deck on the 2nd/living room floor. There is a bright light over the deck, but there is no light switch near it or on the same floor. For whatever reason, it is controlled by (2) 3-way light switches: one on the top floor in the bedroom, and one on the bottom floor in the utility room. Why would the light be configured that way? I have no clue. To turn it on or off, I have to go either upstairs or downstairs. So here is where the idea of a smart 3-way light switch came up. The idea was to have it controllable while out on the deck, but still controllable from the light switches. Also, as I get more into the smart devices, I was wanting Apple HomeKit support as I am being heavily persuaded by loved ones to jump over to the Apple side of things and away from Android. Although I'm not fully convinced to make the jump, I wanted support for both options just in case. I purchased this 3-way switch from Meross for about $28, which was great compared to others I had seen that supported both Android/Alexa and Apple Homekit. You only need to replace one 3-way switch to make it smart, so I chose the one in the utility area on the bottom floor. At first I was a bit apprehensive due to not having messed with 3-way light switches before, and rarely have had to change a light switch (primarily rent). So a 3-way was a bit confusing to me. However, Meross made it quite simple with their instructions and wiring diagram. I have attached some photos, 2 of which I've added some notations for some guidance that I learned along the way. Also, your first step should be to shutoff the breaker in order to kill power to the light switch. Safety first. I was not familiar with "Traveler" wires that are used with 3-way switches. I found that these red and black "Traveler" wires connected to the original standard 3-way switch using brass-colored screws. This made them easy to identify. You just disconnect the wires from the original light switch and use the provided wire-nuts to connect them to the wires coming out of the new switch. So here is how it goes, referencing the marked-up wiring diagram and light switch photos I've attached: L = Live = Black wire connected to original light switch T1 & T2 = Traveler 1 & 2 = Red and Black wires connected to brass screws on original light switch N = Neutral = White wire. The neutral wires should be bundled/connected with a wire nut and stashed behind your original light switch, but not connected (mine wasn't). Just undo that wire-nut and add the white Neutral wire from the new switch, then screw on the wire nut again to bundle ⏚ = Ground = Green wire connected to original light switch (If you have one. My original light switch didn't have one) Hopefully that gives enough detail for others (like myself) who have never done this before. Simple enough. So, a few notes: the plate that comes with this switch is slightly skinnier than your standard light switch wall plate. It didn't seem to be a big deal for me, but just something to keep in mind. Also, you have to use the cover plate that comes with the new switch. It is designed to snap onto the switch and doesn't screw on (likely because there are more to the internals of a smart switch to house the additional electronics you don't have with a standard switch). Just something else to be aware of. This was fun to do and really helped solve my problem. I brought it into my Alexa app and I can control the light from my phone or Echo now and don't have to stop drinking on the deck! ADDED BONUS: If you use Alexa and configure this as a "light", you can use it with Alexa Guard, which allows an "Away Mode" with automated lighting. The Alexa Guard will use sunrise and sunset times (based on your location) to know when it starts getting nighttime, and will use some logic to turn your lights on and off automatically to make it seem like someone is home. With my outdoor deck light, this is easy for anyone outside to see and will be a great deterrent and protection. I already have my neighbors confused on if I'm home or not. Working as intended!

I bought this for homekit as i am starting to add some smart switches. I needed a 3 way switch that could replace a dumb 3 way, but oddly, they were quite hard to find. I found this and one from Kasa. this was the only one which worked with homekit, so i went with it (this is also listed on the apple website). Electrical installation was straightforward. I have a standard wall junction box with a neutral, so it was just a matter of making sure i kept the common wire labeled. Everything connected without an issue and tucked into the box. Setup in the app was weird as you have select the correct version, but version options provided didnt sync up with the label on the box. I selected one (guess) and homekit was fine, but it didnt install in the app. I started over (removed the switch from homekit) and tried the next option. This one worked as it completed the install in the app and then automatically finished the homekit one. a little odd, but worked in the end. i have it for about a week and so far, no issues. i do have a weird issue where sometimes the entire circuit will turn off or encounter a power hiccup, but i do not believe that is this switch as it has happened when i toggling the 4 way dumb switch. WiFi is lost with the this switch, but i am happy to say within a few seconds, the switch is back online. Overall, i like the switch.

I’ve used Meross smart switches throughout our house for some time now with no issues. Instructions are well written and the app works well. I control all our lights using Alexa without any issues. I have Alexa in our car and when we are almost home I can have Alexa turn on the house lights so we don’t enter a dark house.

I will start off by saying that I love the Meross products. I have installed several mini smart plugs and single-pole smart switches. They all installed great, no issues. Get them wired, connect your phone to the switch as an access point, add them to the Meross app, then use Alexa Meross skill to get them recognized by Alexa. On this 3-way switch I could not get the phone to connect to the switch. Half the time it wouldn't even see the switch as a network to connect to, then when it did it would say it was connected in the wifi settings, but then the App couldn't connect to it. I tried this on an iPhone 8 and an iPhone 12 and nothing would work. I tried selecting it as a 3-way switch type and standard switch in the app and nothing. I finally decided I would try to connect to it with iPhone Home since it seems to have a different way of connecting. I had to first connect my iPhone to my 2.4GHz wifi, then add device to Home, I assume Home then just transfers the wifi connection settings from the iPhone to the switch (SSID and pwd), and it will then connect to the network. After that I was able to go into Meross app and see it as an unbound device, which I could then select. It was then recognized as a device in Meross app, and then instantly recognized by Alexa. I am not sure what is different about the networking on this device, but it definitely does not behave the same as the single-pole switches I have. I even returned my first 3-way switch thinking it was defective. I hope this review helps others out there that may be struggling with this. I now feel confident in buying more of these for the rest of my house. I would give this item 5-stars if it were not for this wifi trouble.

Good. It works good . Easy installation but the small screw coming with for holding to the box, are very bad (very tight). If I use my old screws the cover is falling down all the time

En los comentarios leí que se podía instalar en un sólo switch y es correcto, la instalación es algo simple pero recuerda siempre llamar al técnico electricista a menos que sepas lo que haces; se ve de buen material y es algo ligero, funciona casi inmediatamente cuando activas el switch mediante Siri o desde la app Home del iPhone, en relación precio y función siento que es justo ($659 con dos switch) buen deal, ahora hay que ver cuanto tiempo dura.

This looks, feels and operates well at a great price. Wish I’d been able to set it up years ago. Just one thing! Getting it set up with Apple Homekit took days and several attempts. Finally buried in some extended setup instructions found on the Meross website, I found the instruction to check the Meross app to ensure that switch had access to Local Network. Mine was turned off and once it was turned on, bingo! problem solved. The Meross folks should add this instruction to their quick notes included in the package. Setup was a breeze after that. Great product!

Easy install but, I would suggest that you have a good basic knowledge of household wiring. Works great with Alexa. I was even able to set it up to do 3 things at the sametime, simply by saying "Alexa theater mode". Then, all at the same time my TV turns on, my overhead lights turn off and my mood lighting turns on. Perfect for movie night. I have a second one that I am planning to install in an upstairs hall. P.S. It also works with my smart watch.

Funciona muy bien, y solo le agregué una tapa encima y quedó súper minimalista.
