Add QPIGS2 support for dual mppt inverter

[johnjohn031]

Hi,
I've got some inverter AXPERT MAX TWIN 11kw with dual mppt tracker and value are read with QPIGS2 command.

Can you add this command?

Thanks,
John

Hi,
I've modified the loop

        inverter.update("QMOD")
        inverter.update("QPIGS")
        inverter.update("QPIGS2")
        inverter.update("QPIWS")
        inverter.update("QLT")
        inverter.update("QET")
        inverter.update("QT")

and modified/added some field.

    },
    "QT": {
        "Last_Inverter_read": {"index": 0, "type": "int"}
    }
}

It work fine.

I've used the MQTT_TOPIC_PREFIX option that is not mentioned on the readme and work fine.
I've 2 dockers, each on an inverter and each with a different prefix.

@johnjohn031 Great work, thanks for sharing!

Hello @lavron ,

I was wondering if it was possible to update the Docker src file to add more visibility with @johnjohn031 change.
Thanks a lot.

Could we get more info on the configuration, what to use there is no documentation but should be very usefull

Buongiorno sono riuscito a far funzionare tutto, mi chiedo perche io non riesco ad arrivarci come sia possibile avere la produzione giornaliera da fotovoltaico come da manuale che allego .
Ringrazio se qualcuno con più competenze voglia dare un contributo.

Partly it's solved here:
#8
Minor changes would be needed in Voltronic.unpack_data(), and that's basically all.
@1967luca will you handle it? I could implement it in the next release, but can't promise when that would be.
