Very easy to setup and get going.
So far so good. I need to have reliable smart-device based garage door opener. I use the Apple eco-system and Homekit, combined with a Homebridge setup, and my priority is to have a smart-connection so I can ask Siri to open the door with my motorcycle communicator (I have Cardo Packtalk Edge) so I can easily park it. First, I had a myQ. I dumped it because they want a subscription to allow smart-home access. For the next few years I went with Aladdin Genie. They are free for smart-home functionality, but since I had that, I had NONSTOP issues with that. It didn't want to connect to my router from inside the house (I have a separated garage, so there is distance between router and the garage connected to the alleyway behind my house.) It would see my wifi, but just blink that it still had connectivity issues. So I got a more powerful router and that thing has no trouble connecting to anything in my garage... except that Aladdin unit. Then I got a repeater in the garage. That had no issues connecting to my router and still, the Aladdin unit had issues even with that. I gave up on the Aladdin when I got locked out of my own garage. It decided to just not connect to the app. Very weird too, it was disconnected right around 3pm, but when I got home at 1am after work, it worked. Maybe they had server issues, but then again, they don't send any emails saying there will be issues. And it happened Monday, Tuesday, then Wednesday. Not very convenient. Now after all that, I did my research and landed on this. The online community who knows Apple Homekit seemed to recommend Meross, and I never heard of them before, and I decided to give it a try. I got the unit and I watched a couple YouTube videos, followed the included instructions, and I had this device up and running in about 30-40 minutes, including tie-wrapping the cables and securing the device. After a few adjustments, learning some functionality in the app (like disabling doors 2 and 3 so Homekit doesn't access them for now, as I only have 1 garage door opener for a 2-car garage) I'm happy to say that this device works great. ZERO connectivity issues so far as my router and my repeater show full strength connection (the Aladdin did too so I'm assuming its on their end). The moment I "flip the switch" in Apple Home, or press the button in Carplay, the garage door opens and closes near instantly. My garage door opener is at LEAST 20 years old and to get it connected, it was just two wires. There is a compatibility list for openers on Meross's webpage so check BEFORE you buy. Because its wired to my garage door, theres no "learning" required and no button to push like an in-car garage door opener. The only thing I liked with the Aladdin device (when it did work) and the myQ was when a signal was sent to open or close the door, or if an automation kicked in (I had a requirement to shut the door after 30 minutes being open,) they had a bright white warning light flasher to indicate the door was about to move, since you didn't push any buttons. Meross's device DOES NOT have that, so if you setup an automation similar to mine, the door will immediately respond without warning. Also, It is important that if you tinker with the wiring, which you likely will be, to verify that you did not disconnect or cause your garage door obstruction safety system to be disabled. Another plus that I have with the Meross is its open/close sensor, which appears to be magnet based. You run the line from the Meross box to the garage door. I have mine at the top corner to my door along the wall, with the additional magnet also right next to it on the door itself. Very similar to window security systems. When you setup your app, it'll go into detail to verify the system is working by using these sensors. What I LOVE about this is that it is not battery based. The Aladdin and myQ used a button-battery-based sensor you stuck to the door which needed to be replaced after a year or two. Not necessary with the Meross thankfully. In fact, the other disadvantage I had with the battery sensor was in winter when the door was very cold as it gave poor performance. And if the battery sensor failed or disconnected due to a dead-battery, or a frozen battery, those garage door openers also failed because it couldn't tell if the door was opened or closed. Thankfully not the case with the Meross. I certainly recommend this unit, especially for people with more than one garage door. I may only have one opener but I know that when I replace that door and add a second opener for that, all I have to do is run another sensor line for that door similar to the way I did my current door and that this package ("meross Smart Garage Door Opener Remote with External Antenna" in case Amazon links this review with other Meross stuff) already comes with that expandability (up to 2 doors out of the box, if you have a 3rd garage door, you need another sensor cable add-on.)

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.

Great product, but needs better instructions
This unit is very easy to install on older dry relay openers. It took about 15 minute. The instructions need a ton of improvements. They do not have a wiring diagram or anything labeled. With that being said, it’s pretty easy to figure out. The stripped purple and gray wires go directly on the terminals for the garage opener button. It does not matter which lead goes to which terminal, just make sure they are connected to the same leads as the wired wall remote control. The red and black wires connect to the open/closed sensor. You will need to buy a few more zip ties to organize the wire down the lift bracket to the opening of the door. The white wire connects to the usb power block that plugs into a power outlet near the opener. Once it is all connected, the set up in the app is very easy. I use Apple Home. I absolutely love it. I added the widget to my Apple car play and now when I get close to my house the widget appears on my car’s screen to open and close the door. In addition, I am alerted on my phone and on the tv screen (using Apple TV) that the door is opened and closed and who in my family did it. I love being able to say, “Hey siri, open my garage door.” This device will not only work for older garage openers but anything that uses a dry contact relay. Overall I am really pleased with it. I did purchase two units and one of the two that arrived was clearly used and the open closed sensor was broken. It was missing sticky tape and zip ties as well. I returned it and will get a new one. The seller should inspect “B-stock” before trying to sell it as new. If you are remotely savvy with electronics, it should take you no more than 30 minutes to install this device.

Pour fonctionner avec Apple Home, il faut impérativement un concentrateur (par exemple apple TV). Pour Google Home il demande un code pour ouvrir. Mais fonctionne avec les deux et s'intègre facilement dans la domotique résidentielle.

Ich nutze den Meross Garagentoröffner und bin rundum zufrieden. Die Installation war wirklich unkompliziert, alles wurde in der App super erklärt und Schritt für Schritt geführt – da kommt man auch ohne Technikkenntnisse definitiv zurecht. Besonders begeistert bin ich von der HomeKit-Integration. Ich kann mein Garagentor jetzt bequem per Sprachbefehl steuern, bekomme Benachrichtigungen, wenn es geöffnet oder geschlossen wird, und sehe jederzeit den aktuellen Status. In der Meross App kann man natürlich auch das Tor steuern, sowie Öffnungzeiten und Alarme für ein offen stehendes Tor einstellen. Ein kleiner Kritikpunkt: Der Reed-Kontakt ist etwas fummelig am Garagentor zu befestigen. Mit etwas Fummeln klappt’s aber auch. Insgesamt ein super Gerät – klare Empfehlung für alle, die ihr Garagentor smart machen wollen, vor allem mit Home-Kit Integration.

Ürün montajı ve tanıtımı kolay. Tek eksik kapıyı sonuna kadar açıp yine sonuna kadar kapaması. Yani açmaya bastığınız an istediğiniz yerde durdurup geri kapatamıyorsunuz ve sonuna kadar açılmasını beklemek zorundasınız. Bu durum puan kırmamdaki en etkili sebep, onun haricinde işlevini yapan bir ürün.
