The Vision
Our OCPP Broker: a powerful
connector in your tech stack
The Solution
An Open Platform and Architecture
HARMON-E
Connecting, controlling & monitoring
Data brokerage
HARMON-E provides set points accessible via API and MQTT, including OCPP data and DER data such as power meter readings, battery metrics, and solar panel information.
System Health
Charging Analytics helps CPOs monitor site data and detect anomalies for maximum uptime. Alerts notify CPOs of critical events in real-time via HARMON-E, email, or API, ensuring control over operations.
Benefits
Benefits for CPOs
Built around an OCPP broker, HARMON-E seamlessly connects charging stations, distributed energy resources (DER), and third-party systems, providing real-time data exchange and streamlining operations.
Independence and Reliability
HARMON-E uses highly available OCPP endpoints that work independently of any CPMS, ensuring seamless integration and robust connections. Each charging station has a dedicated broker, offering superior reliability and performance through a distributed architecture.
Seamless integration with 3rd party services
HARMON-E simplifies integration of third-party SaaS solutions like predictive maintenance and scheduling. It supports flexible API strategies and is compatible with OCPP standards (1.6 to 2.0.1), ensuring future-proof flexibility.
Hardware flexibility and simplified management
HARMON-E’s broker enables smooth OCPP communication, streamlining operations with batch management of charging stations. A single Websocket URL simplifies configuration and ensures consistent performance across all chargers.
Centralised data storage and access
The platform includes a central data sink independent of the CPMS, ensuring high data quality. All data is consolidated for easy access, analysis, or integration with third-party software, providing a consistent source of truth for your operations.
Efficiency, flexibility, and cost savings
HARMON-E captures real-time data like connection statuses and errors, helping you resolve issues before they affect your business. Its open platform supports third-party solutions and simplifies CPMS switching by updating the Websocket URL. Optimized for energy use cases, HARMON-E reduces costs and complexity compared to full CPMS systems.
