How to pull SOC levels off Venus OS.

We want to feed SOC levels from a Cerbo GX in the field into an ESP32 microprocessor programmed with Arduino IDE. Use when SOC levels fall below certain presets, different load shedding regimes for a 300 home mini-grid would be triggered by the ESP32.

Hi,

I want to control an 8 channel relay card depending on the SOC, via an Arduino ESP32. Can you tell me how you succeeded in your project please?

You can use MQTT or Modbus-TCP to fetch data from the Venus device over ethernet.
The Modbus-TCP register list can be downloaded from here:
