The project captured, stored and shared power generation and usage data from domestic renewable energy installations, including solar, wind and solar/geothermal sources. It used low-cost, off-the-shelf systems to transmit data to a central repository, enabling students and researchers to query and analyse the data in multiple ways. The initial deployment utilised open-source energy monitoring devices manufactured in North Wales, which were easy to install, expandable for additional sensing and control, and transmitted data via domestic internet connections. All contributed data was anonymised, with source locations limited to partial postcodes.
