Smart energy management for 217 garages in Milan with OPTA and smart energy meters

Thanks to OPTA and the 7M Series energy meters, it's now possible to monitor consumption, minimize expenses, and promote more conscious energy use.

A cutting-edge initiative has revolutionized energy management for 217 garages spread across four levels in the city of Milan. By implementing a state-of-the-art IoT system—comprising the OPTA programmable logic relay and 7M Series energy meters—both the condominium administrator and individual residents can now efficiently and personally supervise and regulate their energy consumption across various garages. This project arose from the need to accurately account for each garage's electricity consumption and to make this data clearly accessible to all stakeholders. The ultimate goal is to optimize energy usage and introduce a flexible billing system based on actual consumption.

The adopted solution involved installing 217 7M Series smart energy meters and 11 OPTA smart relays. An advanced and secure IoT infrastructure was created to collect real-time data and make it available through customized dashboards. System integration included software configuration, pairing and mapping OPTA devices to the cloud, and managing differentiated access to these dashboards based on user type. With the support of the software house DNDG, a dedicated web application was developed for both the administrator and residents.

The dashboards offer distinct functionalities: the administrator's interface allows for viewing aggregated data and historical readings, setting time-of-day based tariffs, and exporting data in Excel format. Conversely, the resident's dashboard provides access to historical readings, consumption visualization, multi-garage management, and the activation of additional services. This project is a striking example of how IoT technology can significantly improve energy management and efficiency in complex residential contexts, providing both administrators and residents with powerful, intuitive tools like OPTA and Finder smart energy meters to monitor consumption, minimize expenses, and promote more conscious energy use.
