The PiDome platform is a domotica/home automation platform which consists of a server, clients (desktop/phone/photoframe) and client libraries to build clients yourself.
The server is primarily build to run on the raspberry pi, with other platforms supported in the future. The clients run on every system capable of running java. The client libraries are written in such a way to be able to be used on all possible java platforms and android.
It is quite a young project and currently only available as alpha release with both most stable regular downloads and with ad-hoc builds available.
