no, I'm working on a completely new codebase, based on AMQP messaging (vs DCE). Most stuff is written in python, the Z-Wave part is handled via the OpenZWave library. 1Wire is also supported. Will be fairly easy to extend the system. It also comes with shiny cloud features (portal where you can control everything [even multiple installations]). No 1,5y learning curve :-)
