As a former MyQ user, I can say definitively that this is accurate. There's a magnetic sensor that you put on the door for it to track the state of the door, so the app is always correct on whether it's open or closed.

Yes, but according to their statement, the official client seems to behave better than the HA-implementation. Maybe HA is brute forcing something, like pulling state every 10 seconds or so. And this is a legit complaint from their side if this is the case.

Probably because the official client only checks the state if you open the app, while HA probably does it every so often.

Legit solution would be for the company to allow local access to the garage door to check the state without needing to go through their servers.

If pulling the state goes through the cloud app it is their (self-inflicted) problem.

Sure, and because it was their problem, they made it the problem of those who gave them this problem, and pulled the plug.

But let's get real, 0.2 of customers are probably also matching around 0.2% of their income with those products. So it's probably not really a problem, short term.

Long term, they probably have damaged their brand hard, and missed out on some revenue from grassroot marketing. But that's a problem of future chamberlain. Today, the one responsible for this has solved their problems, calls it done and gets their paycheck.

And who knows, maybe next year they switch to Matter, get some good marketing from it, raise the sales and the victims from today are forgotten. That's business..

any home IoT solution without a cloud inbetween and which shall also be able to communicate with you while on the go requires a lot of technical expertise (and perpetual maintenance...). It is therefore not viable for the mass market.
