*2.5. Novel Contribution*

Due to the existing limitations of the website that stores the data on the variables of electrical consumption homes, this research realizes a platform that allows to visualize the different electrical variables *v*, *i*, *p*, *q*, *s* and *PF* in real time with data upload every 0.5 s from the SMs installed in the different homes. In addition, each user has an app that allows to visualize the data in real time. Since the measured time series are below 1s, a large amount of data is produced for each of the measured variables, so they must be treated by NoSQL data management system and structured storage, which reduces the processing time. Included in the platform is the comparison between different households, which allows to analyse all the households that have been monitored since 2018.

The design of the measurement equipment and data upload to cloud are other advantages this research provides/achieved. The data uploads to the cloud every 5 s, and the data storage in both the cloud and measurement equipment have a data limit of one year. The SM was designed with a cost of EUR 46.28, considered as a low-cost equipment. Being an open-source equipment, it can be programmed according to the needs at any time and for each user.

After analysing the different existing platforms, this work adds the following innovations.
