This feature works great for my voice with no issues. Here’s the catch. If my wife try’s this command it says unable to connect app. This is with her sitting next to me saying it after I have done it with no issues. I discovered because I setup her phone by itself after mine works flawlessly. She wasn’t in the car when I set her phone and I left my phone shutoff while doing this and used my voice with her phone and it worked fine. It doesn’t work on her phone or mine with her voice using the “hey Mercedes” command. Crazy

How do you specify which of the three garage door buttons to use?

Don't the system have a training option to train the voice? I can't remember what is it called.

Does it use homelink or uses alexa or myQ integration?

I'm a bit confused with the problem description. This feature uses MyQ, so for it to work, one's MyQ account has to be connected to one's Mercedes me account. My generation car doesn't support this and as far as I know it's still a beta feature, so I haven't set this up myself. I do have MyQ, though and a complete smart home, so I can do the same by saying "Siri, open the garage", and/or open the garage from the phone directly or the CarPlay dashboard. As said, for this to work via Hey Mercedes, the two accounts have to be linked. For it to work for two separate drivers, I assume both would need their own Mercedes me account and the Mercedes app on their phone and then link the MyQ account to their respective Mercedes me accounts. It doesn't have anything to do with voice recognition. There's no longer a need to train these systems. It recognizes any voice, but the MyQ integration has to be done correctly for each driver's Mercedes me account. Since it's still in beta, though, I'm not even sure it supports multiple drivers. It doesn't even support multiple garage doors currently. If you have more than one garage door it opens them all at once if I remember correctly. I've commented before that this integration is a solution in search of a problem and it's half-baked. Much easier, simpler and quicker to just press the physical Homelink buttons.

I also have MyQ but have not bothered to set it up to operate through Hey Mercedes voice command. It is much easier to just push a button via Homelink in the car to open/close the specific garage door that I desire (Mercedes voice command will open/close all garage doors indiscriminately if you have set them up through MyQ).

I have MyQ as well and have it set up. Works fine but it’s usually a lot easier to just press the button on the mirror.

Somebody will probably bring up that in addition to opening and closing, you can also ask it about the status of the garage in case you don't remember if you closed it. That's definitely a great feature, but again its implementation is cumbersome. Instead of having a simple visual indicator somewhere to see right away if you forgot to close the garage, you first have to ask Hey Mercedes and then wait for the answer and if you forgot to close it, you have to issue yet another voice command instead of simply tapping a button to close it. There are much better ways. For example I can glance the status of my garage door and my entire home for that matter directly from my phone's lock screen and if I forgot to close/lock anything I can tap on the widget and go straight to the Home app from where I can remotely secure the house. In addition I have automations set up that close the garage automatically after 10 minutes. Somebody will say they have small children around the house, so automatically closing the garage door is dangerous, but so is remotely closing it w/o line of sight. I know we are not supposed to use our phones while driving, but now that pretty much all smartphones have always-on displays, I don't even have to pick it up to wake up the display. Just a quick gander and done. It's doubly useful to have this information in a single place on my phone, since I leave my house through the garage on foot more often than I do by car.

I just set my opener to close automatically after 30 minutes if no activity.

I have a somewhat custom home automation that will close the door if I leave my property in the car. No voice command needed. It even knows which car I am in and which door to operate. It will open automatically when I get home. It's a detached garage that is only used for cars so no chance of inadvertently opening and allowing someone in my house. Works on my motorcycle garage door as well. No MyIQ or other garage door system being and I also have AA integration with buttons that appear on the center display to see the status of all the doors and I can open/close with the buttons from anywhere as long as I have Internet.

Yeah, automation is essentially the way to go. I have a similar automation, but I have it set up to require confirmation and it ties in with the house, not just the garage. As soon as I enter the geofence around my house it brings up a prompt on my phone and if I confirm then it opens the garage, unlocks the door to the house and disarms the alarm system. Similarly when leaving, I tap one button and it closes the garage, locks all the doors and arms the alarm system. This works whether I'm on foot or in my car.

I like to visually verify the garage door is closed. Has happened a few times on a windy day: The door gets almost completely closed and a leaf blows into the garage, crosses in front of the door sensor and the door either stops or pops back open. In winter, snow/ice will also interfere with the closing, the door thinking it's hit something and pops back open. Ah the joys of living in rural Maine....

That's what notifications and the door status is for. Obstruction is one of the statuses and if the door is obstructed, I get a notification on my phone.

So somebody convince me why the always reliable button on my rearview mirror is so 15 minutes ago.

I thought we established that the physical buttons are not 15 minutes ago to just open/close the garage. As I said in my initial post, having to use a voice command is more cumbersome than just pressing the button. However, being able to open/close one's garage door from the phone opens other use cases such as opening and closing it when not in the car, or from the CarPlay dashboard when driving a service loaner etc., or tie it to automations that do more than opening and closing just the garage door when leaving or arriving. These automations can technically also be triggered via the Homelink buttons, since Homelink can control more than just gates and garage doors.

What the buttons don't do is indicate if the garage door is actually closed. Many times in the past I closed my garage door w/o thinking about it and then a few blocks away I wasn't sure anymore if I actually closed it. Similarly, in the past, leaving the house involved manually arming the alarm system, then locking all the doors and finally closing the garage door. Now I tap one button and it does it all and it gives me piece of mind if I'm away on a trip for example and can see on my phone that everything is locked and closed and remains so during my absence. If there was a break in, I'd be notified right away in addition to the alarm company. At any time I can also remotely unlock my front door or add a guest code to let somebody in during my absence if something comes up. Bonus points for not having to carry a key chain anymore and be locked out of the house if I leave it somewhere. This actually happened to my wife once. Now my locks have a built-in key pad, so I can always get in, even if I lose my phone.

Ultimately, we are talking about enhancing the basic Homelink buttons that don't provide two-way feedback such as the status of the garage door. These smart openers allow for automations, remote control and status information.

I don't think anyone is saying that so there is no need to convince you. I can still hit the button in the mirror too, but if I forget or the door fails to close for any reason, I get notified and the door will automatically try to close. When I come home, the door automatically opens. I can still use the button in the car and still do if the automation fails. I simply add the automation because I think it's cool and it's something I like to tinker with.

Home automation is an entire topic by itself, and like many others I have remote monitoring capabilities that include security cameras, temperature sensors, door and window status, backup/UPS power, etc. I just haven't found a reason to merge my cars' door openers into the mix.

Aren't we all saying that? The MyQ integration doesn't do much that the buttons don't already do for the most part and is less efficient/more troublesome.

No - the OP was complaining about the unreliable activation with his wife's voice, not making the car's MyQ system part of his home security complex.

Neither was anybody really championing replacing Homelink with MyQ, so who were you hoping to convince you? Were you looking for OP to convince you why they want to use this over the Homelink buttons? Arguably, the discussion deviated into home automation mostly to say it's not worth bothering with MB's MyQ integration and just stick to the Homelink buttons. Use MyQ etc. for other use cases. At least that's how I'm looking at it.

Yes, that's exactly it. My experience with voice command systems has been dismal. Cars can't seem to differentiate my voice from road noise (perhaps there's a subtle message there), and no matter how distinctively I attempt to articulate each vowel, consonant and syllable, the car remains clueless. I say "Highlands" and I hear back "Hawaii, is that right"? Having to pull off the road and stop the car, turn off the audio system and recite the same command 3 times while still not being understood is not worth the effort when pressing a button will do the job. Call me a Luddite -- I'm not offended.

I hear you, although voice recognition systems work quite well for me. I'd say 90% or higher success rate and I continue to be amazed by how well the one in my car works despite all the road noise, engine and exhaust roar that my AMG produces. Having said that, OP's issue is not a voice recognition issue. "Hey Mercedes, open the garage door" does not use the car's Homelink. Did you think it does? It's a completely separate feature and uses MyQ. Therefore this feature has to be discussed and understood in the context of smart home tech. As I said in my first post, for it to work, your MyQ account has to be properly linked to your Mercedes me account and you have to have the Mercedes app on your phone. The error message that OP's wife is getting is not that it doesn't understand her, but that it can't connect to the app to find the MyQ information. My guess is that his wife doesn't have her own Mercedes me account that is linked to his Mercedes me account in the Manage Users section in the app, so when she's trying to use it, it doesn't find the necessary MyQ information. She needs the Mercedes app on her phone with her own personal Mercedes me account. Then he as the primary driver needs to link her Mercedes me account to his, so that the car finds the MyQ information when she's trying to use this feature. As said, it's a lot of hoops and configuration to go through for something that's a simple button press to accomplish the same thing.

I suspect you are correct regarding why the voice is not working for the wife. It being worth the trouble to setup is dependent on one's ability to configure this stuff and desire to tinker. A seemingly impossible task for some is trivial task to another.

Voice command seems to be just about the only thing in my AT that works reliably....and that's amazing when you consider I have spasmodic dysphonia (think RFKJr.)

I configured this on the car because I was under the impression based on my car sticker that the car didn’t have homelink. There was I line item that said minus homelink. I assumed they had a supply chain problem and built the car without this feature. Seems that everyone here has that feature so I will try to program it when I get the chance, definitely would’ve saved me some time
