Just released the first version of my Z-Wave middleware: zfunk
I started with Z-Wave by buying a RaZberry daughter board for my Raspberry Pi. After testing several management applications, i decided to develop a solution by myself, because i was quite disappointed with the available apps. I want to have a robust and layered software architecture, which works well with my devices. And no all-in-one application, which may work with many devices, but not with mine very well. So i decided to begin with a simple REST server connected to the the Z-Wave controller to offer the OpenZwave API for the web and be consumed by other applications.
For Apple HomeKit support please try homebridge-zfunk.
