The NetHomeServer is a software/hardware project for home automation. The core functionality of the home automation server is to integrate functions like lamp control, temperature measurements and control of audio and video equipment into one framework where it is possible to mix and match devices from different vendors and build features which integrate functions from all kind of units. The core is a server program which is easy to install and runs on Windows, Linux and MAC OSX (probably on many others as well).

The server itself is written as a set of loosley coupled modules which exposes an interface consisting of attributes and methods. The modules are connected to a common message bus where they can listen for events in the system and send events when something happens. Here you can see an index of the modules that are currently avaliable.
NetHomeServer interfaces with a number of avaliable home control systems like:
Home built hardware for control of IR and Radio devices. Read more...
The different systems have different prices and feature sets. See here for a comparison between the systems.
