Class extension/inheritance

[jordanj-pl]

Hello everyone, I was trying to extend OpenTherm class by adding additional requests. Unfortunately when I run the extended class communication with boiler does not work. Exemplary code is attached here below. Do I do something wrong?

Du summarise. When I run
OpenTherm *ot = new OpenTherm(1,2); ot->begin(handler);
it works. When I use the extension i.e.
OpenThermExtension *ot = new OpenThermExtension(1,2); ot->begin(handler);
it does not. Obviously it compiles without any warning.

`
class OpenThermExtension : public OpenTherm {
public:
OpenThermExtension(int in, int out);
float getOutsideTemperature();
};

OpenThermExtension::OpenThermExtension(int in, int out) {
OpenTherm(in, out, false);
}

float OpenThermExtension::getOutsideTemperature() {
unsigned long request = buildRequest(OpenThermMessageType::READ_DATA, OpenThermMessageID::Toutside, 0);
unsigned long response = sendRequest(request);
Serial.println("Response: " + String(response));
float temp = getTemperature(request);
return temp;

}
