The system monitors energy consumption at electrical board level, through the installation of the Univeral Monitoring Device that enables the transmissions with the server of the information gathered through network analysers and current sensors. This communication between these two devices is done through Machine-to-Machine (M2M) such as GPRS, WiFi, SigFox, LoRaWAN, etc. The UMD enables not only the monitoring of energy consumption but also the possibility to act in some circuits thanks to the switches installed for this purpose.
