promixis web site lists z-wave as a supported, but I've downloaded Girder 5 looking for any specific mention and have not found it.
I can personally see how to do it; Leviton VRC0P Z-wave<>RS232 bridge, then use Girder's generic Serial plug-in; Then I write a macros to send commands.
But please someone tell me someone has worked on this and has a better way.
Cheers,
