I was an early adopter of the Chamberlain, and was initially disappointed that, while it could pair with IFTTT (free of charge at that time), they refused to let the system be used as a "Then" action, only as "If" triggers...for "safety reasons" (the example given was that closing the door could crush a child, insert eye roll here). I gave up on integrating it with anything other than my security system, which essentially just groups it with my Nest thermostat into a one-stop dashboard on my phone that I almost never use.
When I was setting up my new Google Home Minis, and saw that Chamberlain was available, I got SO EXCITED, and was even more disappointed that they'd gone back on their "safety concerns" BS in favor of trying to swindle users for subscriptions for each. individual. service. Wanna pair with Google Assistant, which would let you voice operate your door? That'll be $10/year (at the discounted bulk rate). Double that if you also want to pair it with IFTTT. I'd love to find the person responsible for this and punch them in the throat, twice a month. But I'll do it at a discounted rate so they only get 20 punches per year instead of 24. Jerks.
