OSGi Community Event 2015 There is already a broad spectrum of smart home products supporting their users in many ways in their everyday life. However there are also many products that can be categorized as "gadgets" that users quickly forget after the initial enthusiasm.</p> Security at home and reduction of energy consumption and costs are among the most requested features for smart home systems. Being honest, available products don't really fulfill this promise, since the acquisition cost can't be amortized for many years. Additionally, users need to be technical experts in using and customizing the system. Germany is heavily investing in the so called "Energiewende," which aims to use as much as possible renewable energy sources and less from traditional power plants. However, the energy network has not been designed for this. ProSyst and the peak lab., together with the German utility EWE and many other partners, collaborate to make the "Energiewende" a reality as part of a research initiative called "enera" with a total budget of 200 million €. This requires to connect all components in the grid from power plants, windmills, up to smart meters and smart home systems. Smart home systems are key for the success as they build a direct interface between consumers and utilities. Data collected from the grid needs to be analyzed with Big Data technologies to understand how and where in the network the energy consumption can be optimized. This data can be used to build new business models that will help to motivate users to directly participate in the realization of the "Energiewende." The project is going to use OSGi technology to build a non-discriminatory smart home ecosystem that is also open for the participation of startups and small medium enterprises offering a big variety of smart home / smart energy related services providing new exciting interfaces and user experience. We are going to present the challenges for building such a complex and connected environment as well as the role of OSGi for the realization.
