Chamberlain is dead set on chasing away free access to its MyQ ecosystem of products and focusing on making it a paid platform for anyone looking to do any more than use its app to open or close your garage door. Ending support for third-party platforms like Home Assistant.
The company has recently announced that it was going to kill off API access to anyone outside of its authorized partners. Calling it unauthorized usage of its services and that this helps the company provide the best quality service to its customers (through, you know, trapping them behind paywalls).
Those using Home Assistant and other platforms to integrate MyQ into the rest of their smart home setup are now left dry without any way of achieving this without using IFTTT (which will run you a monthly charge unless you only use it for a couple of triggers with MyQ and literally nothing else). You can integrate it with certain vehicles like Tesla but it comes at an even higher cost.
So in the end, it all seems to come down to maximizing profit and a complete withdrawal from the open connectivity communities. Chamberlain is a member of the Connectivity Standards Alliance (the organization behind the new Matter protocol), which is surprising since it leans in the opposite direction of the moves it has been making to chase away ease of access to its devices. So it will be interesting to see what comes of that if anything.
For those looking to continue using their smart home ecosystem without an additional charge of some sort, you will have to look for an alternative solution to replace MyQ in their garage space.
