That's strange, the Lutron tech support rep made it sound like this limitation applies to all versions.
I think I saw 5.5.4 on the dealer's laptop screen (if I remember correctly). Do you mean that 5.5.4 is "really old"? Could you tell me the latest version so I can check it against his version next time he comes over?
I see some courses listed on the Lutron website entitled "RadioRA® 2 Preferred Systems Provider Accreditation Training" and "RadioRA 2 Preferred System Provider Training." If I sign up for one of these, is it free, and when I get there are they going to ask if I'm a dealer or be cool with the fact that I'm just an end-user?
