NEMESIS - Industrial EquipMent Energy SupervisIon System offers an energy supervision system for industrial equipment, allowing real time measurement of electrical parameters inside industrial applications. The energetic industry relies on devices from multiple companies that operate with different protocols and are not interlinked. We aim to support data transport standardization and prediction across heterogeneous equipment in industrial facilities. Our solution enables data gathering from multiple points with smart devices, uploading it in the cloud and providing a map of the entire system. We also offer differential access to cloud data, taking into account users’ permissions.
