In recent years there has been a growing development of applications oriented to energy saving, based on the Internet of Things and cloud computing. These developments have not only economic motivations, but also environmental ones, related to the reduction of greenhouse gas emissions. The energy sector is perhaps the main global contributor to the emissions of these gases. In the present work, the development of a system based on IoT and CC for the monitoring of energy consumption at the residential level is described. It is organized according to the three-tier model: Edge, Platform and Enterprise. At the Edge level, some innovations are proposed, such as indirect energy sensing and the connection of sensors using the electrical network for data communication. Both would enable an agile deployment of the sensor network. The objective of the system is to provide the user with feedback about their energy consumption and certain environmental variables, in such a way that they can manage their energy consumption, while still achieving an adequate level of comfort.Facultad de Informátic
