The Virtual Energy Hub/ OEHU is a public, open-source, distributed database for smart meter data . Users can contribute their data and in return gain access to a personal dashboard , detailed datasets from all contributors, and cloud-based data analysis tools.
The primary goal of the Hub is to make energy data more accessible for the people who actually produce this data (i.e. everyone). Obviously, this goal is closely aligned with the movement for self-sovereign and community-owned data, a movement that has been growing in recent years thanks to Distributed Ledger Technologies such as Blockchains.
You will need a Raspberry Pi, that you connect to your smart meter. To get started visit https://oehu.org/get-started
