AFAIK it's an ASCII interface and the only way to get the API
documentation is to purchase a developers kit from Zensys for oodles
of moolah. You might find more info at LinuxMCE.

I haven't looked at Z-Wave in detail since shortly after it was
introduced. The high cost (hardware and API), high complexity network
(difficult to setup and maintain) and inherent limitations (there were
a limited number of modules that could be used in a network with
limited range and a limited number of hops between modules - you were
likely  to run out of modules/hops before you ran out of real estate)
convinced me to forget it. It may have since been improved but I'm not
going to waste time exploring it again. Zensys is now a division of a
larger company and may not get a lot of attention or funding.
