In response to the increasing need to digitalize energy consumption and the growing demand for data transparency, this bachelor thesis examines incorporating blockchain technology into Home Assistant to verify domestic energy usage. The project investigates technical feasibility, reliability, and usability of linking a smart home automation platform with a distributed verification system. A proof-of-concept module harvests energy data from Home Assistant sensors and checks it through a blockchain API utilizing cryptographic signatures. Early attempts at implementation via a Home Assistant custom component were put on hold due to stability issues. This pave the way for a transition to an external GitHub-based solution. The transition enhanced system flexibility, modularity, and robustness. The study is justified by a literature review that highlights the use of blockchain in peer-to-peer energy markets, smart grids, and decentralized community energy management. Five recent publications are discussed in depth to guide the project design choices and broader societal applicability. The solution demonstrates how blockchain can be employed practically to increase the trust in smart home energy data. These insights facilitate future applications including dynamic energy markets, integration of charging points, and sharing at neighbourhood level.
