The Eclipse SmartHome project is a framework that allows building smart home solutions that have a strong focus on heterogeneous environments, i.e. solutions that deal with the integration of different protocols or standards. Its purpose is to provide a uniform access to devices and information and to facilitate different kinds of interactions with them. This framework consists out of a set of OSGi bundles that can be deployed on an OSGi runtime and which defines OSGi services as extension points.
The stack is meant to be usable on any kind of system that can run an OSGi stack - be it a multi-core server, a residential gateway or a Raspberry Pi.
