Apparently you can hijack the mqtt setup and manage it locally (I mostly wanted to know if I forgot to close the door, so I'm pretty okay with the Meross app).
I guess it doesn't have the built in support for the obfuscated protocol, my opener is just a dry contact so I didn't need to look into it.
I also got a Meross garage door opener, primarily so the kids could get in and out of the house without having to shuffle our two physical clickers around every day (depending on who would be home first).
My wife commented that it's the only useful technology I've ever implemented.
Like you, and haven't yet done the "make it work locally" hijack thing yet - but I haven't needed to because it works well.
Knowing that the door has been left up has also come in handy a couple of times. Also been able to open the garage door to let people into the house to feed the pets while we're away.
Only issue I had is that the WiFi range on the single unit is woeful. I had to put a WiFi repeater within the garage for it to see the signal.
I don't know how anyone could stand to work at Chamberlain. Getting rid of the previous HomeKit integration they supported, basically for no good reason other than greed, is corporate brained idiocy.
That has to be some kind of fallacy. Just because something grew large, doesn't mean that it always does good things.
Along the lines of your comment: Apple sent private security that impersonated the police into a personal man's home, but Apple is so large, that means that was okay, right?
A bit of fiddling to get it properly flashed and configured, and ever since it's worked flawlessly with HA.
MyQ is nice, especially with the account management and easy door status viewing from your smartphone anywhere at any time. But I'm not up for the enshittified exorbitant rent-seeking subscription fee and needlessly closed API interface.

It's a reverse-engineered device that you can attach to the opener. It works perfectly, and provides local control and monitoring.
You can also use it alongside the official myQ client, if you want to use in-garage delivery from Amazon.
