Planning to migrate from LightwaveRF to Z-wave.
LightwaveRF seem to be taking a lifetime to move forward and i am fed up waiting.

So plan moving my home made control software over the the new protocol but seem to having problems finding out where i can get the API / Protocol info and maybe DLL's required.
New the z-wave, but all seems to be locked away behind expensive SDK's and non disclosure agreements.

Anybody done / tried this before or got any pointers where to look ?
