ModbusSMA

modbusSMA is a smal and easy to use library for accessing the modbus interface of SMA inverters.The following code shows a basic example:

#include <modbusSMA/ModbusAPI.hpp>
#include <vector>

using namespace modbusSMA;
using namespace std;

int main() {
  ModbusAPI mapi("127.0.0.1", 502); // Create the main API object

  // Call further configuration functions here.

  ErrorCode err = mapi.setup();        // Connect to the modbus interface with ModbusAPI::setup()
  auto      reg = mapi.getRegisters(); // Get a pointer to the RegisterContainer where all registers are stored.

  // Use the shared RegisterContainer pointer (reg) to get a list of supported registers.
  vector<uint16_t> toFetch = {30051, 30053, 30529, 30535, 30538};

  err = mapi.updateRegisters(toFetch); // Fetch the values of the registers and store them in the RegisterContainer

  // The fetched register values can now be retrieved from the shared RegisterContainer
  vector<Register> registersWithValues = reg->getRegisters(toFetch);

  return 0;
}
