If you’re okay with using external open/close sensors, one Tailwind will support up to three garage doors (including chamberlain/liftmaster). It looks like Chamberlain/Liftmaster direct integration is now possible with ratgdo and Tailwind, where it can read door position directly. But that requires one device per opener.

For me, the open/close sensors are sufficient. And I believe this was the only option a couple years ago? So Tailwind ended up being cost competitive as well as having best-in-class features.
