No, but as I mentioned above, community-created, reverse-engineered workarounds are probably the best we can hope for here—as with SmartThings, given Chamberlain’s lack of enthusiasm. After writing the above, I was actually able to port the DTHs and SmartApp from ST to Hubitat with minimal code changes. I haven’t tried setting up the devices themselves yet in Hubitat to see if they work, but I imagine that would work just fine (I’m still using them on ST but plan to move them over when I have more time).
