my-PV & Victron: Intelligent Data Integration with Node-RED

Practical example: Temperature display from the AC•THOR

In a current use case, the water temperature is read from the AC•THOR via Modbus TCP. With the help of Node-RED, this value is mapped to a virtual temperature sensor and then displayed in the Victron VRM Portal.

The solution is deliberately kept simple and demonstrates how quickly and flexibly my-PV devices can be integrated into existing Victron installations. In addition, more advanced, cross-system control strategies are also possible.

What the my-PV & Victron integration offers:

• Modbus TCP connection of my-PV devices to Victron systems

• Visualization of live temperature data from the AC•THOR in the VRM Portal

• Display on mobile devices and smartwatches

• Data processing and logic via Node-RED

• Expandable to additional sensors and data points

In principle, all devices that provide their values via Modbus TCP can be integrated. Any potential challenges mainly relate to local network configurations rather than the system architecture itself.
