[Case Study] EnergieServe’s Energy Monitoring Solution with Gravio

Executive Summary

EnergieServe, a Singapore based provider of energy management solutions, conducted a Proof of Concept (PoC) to evaluate the feasibility of integrating external devices for real-time electrical parameter monitoring. The solution was built around Gravio as the middleware for data aggregation, processing, and visualization, utilizing the MQTT protocol to seamlessly connect various power meters and gateway devices.

The PoC successfully demonstrated how Gravio collects, filters, and displays energy consumption data on a dashboard while maintaining compatibility with third-party visualization tools like ThingsBoard and Grafana. This solution provides businesses with a scalable, no-code energy monitoring system that can easily be extended for real-time insights, automated alerts and many other Gravio adapters enhancing operational efficiency.

Solution & Implementation

Technology Stack

Gravio was the tool of choice for integration in the energy monitoring system, receiving real-time data from power meters and gateways via MQTT. The system components included:

‍

• Devices & Sensors
  • HeYuan Digital Power Meter: Measures and reads electrical data, integrated with an MQTT gateway via Modbus.
  • Four Faith MQTT Gateway Router: Converts Modbus signals to MQTT data and transmits it to a local Mosquitto MQTT broker.
  • Eniscope Digital Power Meter: Publishes real-time power consumption data via MQTT to the same broker.
  • ASUS Industrial Fanless PC: Runs Gravio, hosts the Mosquitto MQTT broker, and provides dashboard access.
• Gravio's Role in the Solution
  • MQTT Data Collection: Gravio subscribes to energy consumption data streams published by power meters.
  • Automated Data Processing:
    • Uses JSONPath filtering to extract required electrical parameters (e.g., V1A for voltage readings).
    • Performs real-time event-driven processing based on incoming data.
  • Visualization & Dashboarding:
    • Displays filtered energy consumption data on Gravio’s Coordinator Dashboard.
    • Supports third-party visualization tools like ThingsBoard and Grafana.
