This work proposes the integrated management of energy consumption using a low-cost individual meter, a time series database and a time series data visualization tool. For this purpose, open source tools available in the cloud will be used and the design of a prototype of a low-cost individual energy consumption meter will be carried out. This meter will be installed individually in appliances and other household equipment to measure their independent consumption and thus identify the devices that produce higher consumption. This meter not only provides accurate measurements of active power, but also stands out for its ability to accurately measure reactive power, making it a valuable tool for understanding and efficiently managing energy consumption in the home.
