That’s great! The support is in the form of a new bridge (leapbridge) for the existing Lutron binding. The existing ipbridge uses Lutron Integration Protocol (LIP), which is supported by HomeWorks QS, RadioRA 2, RA2 Select, and Caseta Smart Bridge Pro, but not by Caseta Smart Bridge. There is a newer protocol called LEAP that is supported by both Caseta bridge models and also by RA2 Select. The new leapbridge should theoretically work with all of those, but so far has only been tested with Caseta Smart Bridge Pro and RA2 Select.
It’s still an alpha version at this point. Once I think it is beta quality I’ll post a link to it here, but for now I’ll send you the link in a PM.
