Background
A mid-sized commercial facility with multiple tenants needed an intelligent energy monitoring system to improve visibility across floors, departments, and tenant zones.
The goal was to automate data collection from existing Carlo Gavazzi EM340 energy meters and build a real-time dashboard for live and historical insights.
The Challenge
- Manual meter readings were time-consuming and error-prone.
- No centralized system existed for real-time energy data visualization.
- Peak load times and consumption anomalies were going unnoticed.
- Facility managers lacked data-driven insights for tenant billing and optimization.
- Inability to access data remotely or receive alerts on energy thresholds.
