Re: [mh] zwave info...

[Stu W. <st...@bl...>]

Is the Leviton device you got the "RZC0P-1LW- Plug-In Serial Interface 
Module(Zwave)"?  If not, which one have you been using?  I'm glad you 
said something, because "button pushes" are exactly what I want to 
track.  I assume your driver is for Linux?  I've been looking for an 
excuse to rewrite all my windows specific code and get that insecure 
win2k box off my network...
