My garage is now smart
All-in-all, this little device works well and consistently, giving me remote access to opening/closing my Genie garage door. I purchased this MSG100 just a bit over a week ago. I was initially surprised to find some pieces missing (little screws, adhesive pads, test wire), so I reached out to Meross to see if there was anything they could do. They were able to send me a new package, this one with the missing pieces. Now that I had everything, I was ready to set it up. It really wasn't that difficult. I was initially worried that I didn't know enough about garage doors to do this, but it really wasn't that difficult. I watched a YouTube video where someone mounted this that gave a good easy-to-understand visual. They give you a little piece of wire that you can use to connect between two contacts on your garage door in order to test if the device is compatible with your opener. In my case, the terminals I needed to test had a number 1 and 2 next to them (see attached picture). If you would like to test before you decide to order, you can just use your own wire, or take a pair of pliers and bridge the connection. If your garage door opens/closes when you touch it to both of the terminals, then the Meross device will work. Walking through the app will go over all of the directions. After testing, they recommend to go ahead and plug up the device to power inside your home to get it started with wifi setup. If you can plug it up in the garage, that will also let you test if your wifi will reach. Once I had the app setup, I moved on to installing it. I used the provided adhesive pads to stick the device on top of the opener itself, and just bundled the cables together so they're all up there (see photo). The power cable is a USB plug that connects to a regular power adapter, and there should be an outlet just above your garage door opener. The control cable has two leads that now need to connect to those same two terminals that were tested before. The final cable on the device has a red connector that attaches to the long cable included for the door sensor. This was probably to longest part since I had to run the cable across the rail to the door itself. There should already be some wire running across this rail to one of the control levers that stops the door when it's closed. I just followed that and put the new wire under the plastic clips holding the existing wire. In my case, I opted to attach the sensor using the included adhesive pads to the top of the plastic piece that slides along the underside of the rail (the emergency release lever part). This is what the guy did in the Youtube video. It was a shorter run and easier than attaching the sensor on the door, while also serving the same purpose. If you do the same, just keep in mind this plastic piece also hits the levers on the rail to stop it once it's closed, so just put it like in the picture attached so it doesn't conflict. Once all was done, I just opened the app and tapping the garage door icon was opening and closing my garage door! It initially was giving an error saying that the garage door failed to open or close, even though it opened/closed just fine. This is because of the "Opening time" setting that you will need to adjust. This setting tells the app to wait a longer/shorter time before checking to see if it completed successfully. Since my door takes a while to open, I had to change the 15sec default to 20 seconds. Now I don't get the message, and successfully get notifications when the door opens and closes. These notifications work even if you use your manual remote or button in your car to open, which is cool. And on top of that, it also integrates with Alexa. Just download the Meross Alexa Skill and link it, then you can open and close it with your voice. At the end of the day, it works quite will so far and I am very happy with it. I was apprehensive at first due to my lack of knowledge, but it really was pretty simple. And Meross came through and did the right thing to get me the missing parts so I didn't have to return it. Just give them some time to respond. Final note: If I did have one small gripe so far, it would be that once you have it integrated with Alexa, the Alexa app does not have an open/close button that you can tap. So if you do not want voice control, you can't use the Alexa app to control it, so you'll just have to use the Meross app. I'm not sure if it's an issue with the Alexa app or the Meross skill. The Alexa app does not treat the garage door opener like a smart plug with a simple on/off button. I can't dock them for that, but if Meross and/or Amazon are listening: you guys should get together and find a way to have a simple open/close button in the Alexa app just like you do in the Meross app. That way you can use the Alexa app as the hub even if you don't want to use voice.

3 years in and still completely happy
I initially installed my Meross HK100 about 3 years ago and due to a move, had to remove/reinstall. It’s still working almost perfectly. The actual install process could not be any easier and requires no more than about 30 minutes. Once installed, you can sync it up to your Alexa, Google, or Apple device to control your garage door remotely. A well designed app is also available on the Google play or Apple App Store. My only issues have been just recently at times the app does not recognize that the door is closed or open. The actual functionality works with the door opening and closing correctly, it’s just that the app is reporting incorrectly. I believe this is likely tied to the sensor which I’ve confirmed is installed correctly. I’ve also adjusted the opening/closing time as instructed however it doesn’t seem to solve the problem. I’m well out of warranty period but will try reaching out to Meross anyway to see what they say. Regardless of this noted issue, I still highly recommend Meross. The cost to performance ratio absolutely favors the customer.

Cost Effective way to make Old Series II Garage Door Smart.
I purchased this with my series II wall console. This is a very good and cost effective way to make you Old series II Garage door smart. The installation was fine and it works as expected. I am happy that I can control my garage door from anywhere. It uses power connection instead of the Battery. I configured this with Google home to control the Garage door with my voice. However, Google needs a PIN every time I use it to operate my Garage door. I has been working good so far and I would recommend it.

Connects to any opener with a workaround for incompatible models.
I have a Liftmaster garage door opener that is only compatible with 1 smart controller (the MyQ Smart Remote). Problem is, the manufacturer charges a monthly fee to allow Google Assistant or Amazon Alexa compatibility. The amount was minimal but the principal of it really bothered me. The manufacturer claimed they only charged the monthly fee to keep the product price down. However most other smart garage remotes cost about the same amount and include Google or Alexa compatibility free of charge. I had other Meross products and liked them so I looked into Meross. Meross has a workaround that alows their smart opener to connect to virtually any garage door opener. Simply connect the Meross smart garage door opener directly to one of your remotes and, vuala, it works. Great idea. But if you don't have a spare remote then what else can you do? I figured if I can hook the Meross Smart garage door opener to a remote then why not connect it to the wall button. I did some testing and found that it worked exactly the same as hooking it directly to a remote. This made it easy because I could place the Merros Smart GDO right next to the wall button where it was easy to service and also made it easier for me to locate the sensor in a place where it would work well with my garage door. I gave this opener 4 stars because of a couple deficiencies I see in the product that hopefully will be remedied in the near future. Pros: The Meross Smart garage door opener is easy to set up and connect to your Wi-Fi. The app is easy to use. It will connect to virtually any garage door opener even if the opener is listed in the Meross incompatibility list. The app alerts you when the door has been left open for a certain amount of time that you set. The app allows you to check the status of the door and will tell you if the door is open or closed. You can open or close the garage door from anywhere using the Meross app. It is compatible with Google Home and Amazon Alexa without having to add a hub AND THERE IS NO MONTHLY FEE FOR THAT FUNCTIONALITY. Cons: (Deficiencies) Right now the app does not allow you to put the Meross Smart garage door opener on a time schedule to close the door automatically at a specific time. I spoke to Meross about this and I was told that they would consider adding that functionality in the near future. I later found that Google allows you to include a time schedule when setting up a custom routine in Google assistant. This seems to work well and has been fairly reliable. Although you can add the location of your Meross Smart GDO into the app, I have yet to figure out how to make it open my garage door via proximity to my house. Google does not talk directly to the Meross Smart GDO so you have to say something like "Ask Smart Meross to close the garage door." Fortunately Google allows you to create shortcuts/routines that fix that annoying quirk. If Meross would just add a couple simple functions that many other smart GDOs already have, I would give it 5 stars.

Wish I Bought These Sooner
All to often, my wife calls me after she leaves the house to check if she closed he garage door. It's always closed, but I still have to check, so I looked into turning my opener into a smart opener so she could check by herself. After eliminating any device that requires a subscription, the Meross Smart Garage Door Opener emerged as the potential best choice for me and since the price was right, I bought three, one for each door. For some reason, I thought they would be a little larger but they are nice and compact. They arrived quickly and were packaged very well, with three boxes inside the larger (but still small) box, each containing a piece of the puzzle, opener unit, door sensor and cable, and installation accessories (not many). If you're at all handy, installation is pretty easy and straightforward. First plug in the unit (USB powered, adapter and cable provided) and the Meross app and it will connect to your wifi and walk you through the installation process. First one took about an hour, the other two, about 20 minutes each. A few installation tips (I have Marantec openers, yes I had never heard of them before either, but they came with the house and Meross said they are compatible, which they are): * I added a pigtail to the wires that connect to my opener just to give me a little more wiggle room and make it a bit easier. * Have a lot of zip ties around. They provide one, I guess to tie down the unit but I had to zip tie everything near the opener because there were a lot of wires (I also use the opener outlets to power security cameras) and the sensor wire is VERY long (had to coil up more than ten feet). I used 5 inch and 8 inch ties. Didn't need anything larger. * Comes with double stick tape for the sensors, but I also screwed them in, just because (screws are provided). * No special tools needed and if you don't pigtail the connection wires, I'm not sure any tools are needed (other than a ladder, and maybe something to snip the tails off the zip ties). I like the app as well. Somewhat basic but easy to use. Can set up notifications when the door opens/closes, is open for more than a specified period of time (mine is set for 30 minutes), or is open after a certain time (I'm set for 9:00 PM). It will also close the door after a certain length of time (I have this turned off), or after a set time (10:00 PM for me). You can set it to beep when it's closing the door (turned off). Says it works with Alexa , Google Assistant, and optionally, Apple HomeKit but I don't use any of these as I figure there are enough things listening to me already, so I can't comment on those. Also, I've only had it for a short time so can't comment on any longer term issues that may arise, but I'll update this review if necessary. I'm very impressed and if/when I do decide to automate more, I'll look into additional Meross options. To me, it does all I need it to do.

It works! Alexa integration is a bit kludgy.
Update 12/27/2019 The Meross app on my Android phone gets confused. If you open the garage door using the regular door button or wireless remote, the open/close display on the Meross goes out of sync and shows the door open when it is closed and vice versa. To get the Meross app status back in sync, you have to operate the door using the non-WiFi device (button or wireless remote). Even though it's out of sync, the Meross app still works, but displays an error (door open/close failed) and the icon on the app does not display the correct door status. Alexa also performs properly when the Meross app is out of sync, but you have to repeat the Alexa voice command. Alexa incorrectly says the door opened on the first command. The door will open when the voice command is repeated. Once the Meross app is back in sync, everything functions normally. Not sure why this is happening. It's not a deal killer, but it is frustrating. I still recommend the product, but I'm hoping future app updates will resolve the issue. ++++++++++++++++++++++++++++++++++ I'm not quite sure why I bought this item. I guess I'm on a smart home quest and I scored an excellent deal on Amazon. With the on-line coupon at checkout, the unit cost $30 (list price is ~$50). Before receiving the device, I viewed all the installation videos. They were very helpful, but Meross has updated the WiFi controller box so that you don't have to open it up to attach the power, sensor, and signal control wires. It's all done for you. The strangest thing is that the unit is now powered by USB (don't worry, it comes with an AC adapter plug). The first thing you should do before venturing into the garage is to get the unit connected to your network using the Meross app and then linking it to the Alexa voice assistant, if that's what you use (more about Alexa below). Installation was difficult, but that is not the fault of Meross. My detached garage is not heated so I was shivering in 30° temperatures. The most challenging part of the install was attaching the signal control cable to the Liftmaster motor. There were already a couple of wires attached to terminals, so fitting the control cable was a major chore that was made worse by my shivering cold hand trying to get the screw driver in the screw slot (hey, Meross, put on wire spade connectors!). Note that as long as the existing wire connections are maintained, all the other devices that control the door opener (wireless remote, door buttons, etc.) are fully functional. Once that onerous task was completed, the rest of the installation was reasonably fast. Positioning the door sensors was a little tricky, but the sensors seem to be quite forgiving in sensitivity (placement of the sensors will be different depending on your garage door). The only thing remaining to be done is dressing the wires a bit more neatly when the weather warms up. A few words about integration with Alexa. The garage door opener is categorized as a "Lock" in the Alexa device settings. Makes no sense, but there it is. The voice commands are: "unlock garage" (or whatever you named the device in the Meross app) to open the door. Alexa will then query you for a four digit security code that you will have previously entered in the Alexa app (I've not discovered a way to bypass this). To close the garage door, the command is "lock garage". No security code is required to close the door. This is the main gripe I have. The Alexa integration is awkward and unintuitive. I like simplicity and having brief, logical voice commands. Unfortunately, Alexa and/or Meross have some work to do. Perhaps future updates will address this kludgy interface. It would be really nice if Meross products were supported directly by Alexa to bypass the Meross app. Despite the installation and integration issues, I highly recommend this product. It works as advertised (so far, anyway; I've only been using it for a few days). Meross seems to have its act together (I have six of their smart plugs that have worked wonderfully over the past year). Their product pricing, at least through Amazon, is highly competitive and the quality seems excellent. I'm hoping this garage door opener holds up. I will update this review to reflect future developments.

It is a very fiddly gadget (garage opener).
It is a very fiddly gadget (garage opener). It often gets stuck in either open or closed state, while you are looking at the door being in the opposite state. Sometimes you have to close the app, and reopen it, and then it initializes correctly. All the meanwhile, you are sitting in your car fiddling with the app to make it work. Sometimes it does not initialize correctly even when you close and reopen the app. Then I need to go inside the house and open garage door manually. One time the app just signed me out. And I don't have the password in my head. So I had to go inside the house to open the garage manually. It does not do this a lot, but it happened. One time, it send to me a message, and this is after, I watched the door close, and I drove off, and reached my destination, and am interacting with people, and receive a message saying something like your door is stuck open. This may be becaused by the time allocated for the door to open or close being set incorrectly. Shell we go to your garage door and make adjustments. This is not exact wording I got, but something to that effect. At one time I found it would work better if I would turn off the blue tooth that my phone uses to connect to my car. Anyway, it is very fiddly. And it is too bad. Because I prefer using my phone versus storing a dedicated garage opener in my car. And when it does work, it is a beautiful thing. Anyway, that is my experience with it. I have not investigated if good alternatives exist. But if I was to do it from the start, I would not choose this particular gadget. Oh, and one more thing that I want to share, that is not the fault of the system, but is a pretty scary situation. The app has an option to checkmark to close the door after 10 mins of inactivity. It sounds reasonable. As in case you forget to close the door. It will compensate for that. But then you forget that you authorized that. And you park your car right under your garage door, and do whatever, like talking to your neighbor, or do an oil change, or whatever. And all of a sudden, the door starts coming down on top of your car. That is nerve wracking. Again, it is not the problem of the gadget. It is a user problem. But I wanted to "air" this out there, to remind people not to fall into such trap that you your self created. Anyway, I don't know if one star is a fair assessment. Because it does work, with some fiddling, most of the time. But one star is definitely reflective of how frustrating it is. In a very least, fiddling with it by your garage door, most of the time. And in a worst case, having to leave your car, to go inside the house, to open your garage door manually. But also, to get a frustrating message that your door is open, when you are not even at home anymore, and you watched your door close: just a frustrating gadget.

Nice product, but there are some considerations
The most challenging part of installing the Meross garage door opener is installation of the magnetic sensor that is used to determine whether the door is opened or closed. The door mounted part of the sensor is magnetic, but I wanted to ensure that it didn't inadvertently move because of contact or vibration. That meant drilling small pilot holes in the door and using small sheet metal screws to secure the device. Running the wire neatly from the sensor to the device is tedious, but not difficult. You will need something to hold the sensor wire in place. Connecting the Meross app to the network is straightforward, but getting the device to work reliably, particularly with Alexa was a little more challenging. To improve robustness, it was necessary to modify settings in my router. If your router by default supports the following settings great. If you are unable to evaluate or modify either because of skill or lack of access (for example, a provider's router), you may want to pass on this device. After having addressed the following, the Meross and Alexa connections worked as expected and I am pleased with the results. 1. Use 20 MHz channel width (NOT 40 MHz) Meross devices choke on 40 MHz because it increases interference and retry rates. Set 2.4 GHz to 20 MHz only. 2. Use channels 1, 6, or 11 — never 3, 4, 5, 8, 9 Meross expects standard non‑overlapping channels. Channel 5 (your previous setting) overlaps with both 1 and 6 → packet loss → cloud session resets. 3. Disable “Smart Connect” / band steering If your router merges 2.4 GHz + 5 GHz under one SSID, Meross sometimes gets forced into reconnect cycles. Use separate SSIDs or disable Smart Connect. 4. Wi‑Fi Reliability at the Opener (Even if RSSI looks “perfect”) RSSI must be better than –67 dBm You reported –60 to –65 dBm — borderline but workable. Alexa is more sensitive than the Meross app, so even small fluctuations matter.

Very good product and easy to install
Very good product. I was bit sceptic when bought this bec' my garage door opener ATA GDO-2V6 is around 24 years old. I was able to connect perfectly and working like a charm. It's operate easily from mobile and getting "open and close" notification also correctly. Very happy and recommended.

Excelente opción para controlar la puerta del garage desde el celular
Muy fácil de instalar, la misma aplicación te indica paso por paso qué hacer. Su aplicación es muy fácil de usar. Si quieres utilizarlo con Alexa, busca alguna otra opción, ya que solo te agrega el dispositivo pero no puedes manipularlo, te indica que actives la opción de voz pero no se muestra en la configuración.
