Hey there!
No, I don't have hardware yet, but we're going to build a (new) house soon and Lutron RadioRA 3 is on my list of candidates. I just spent a fun-filled evening figuring out the RRa3 world, and it's, uh, interesting. Kinda reminds me of German Quality Engineering - the electrical stuff is first class, but the user interfaces and APIs are... limited.
How stable and how complete does LEAP look to you? Lutron seems to be pushing hard towards RRa3 (deprecating the interface hardware for RRa2 and with it, pretty much, Telnet mode).
Has anyone actually bothered to write up the protocol, or should I just read your code and follow along?
Short of buying a toy RRa3 system (that would be 6-9 months out for me), is there any way I can help?
Cheers
