Change in request load classes

[JeB2022Nov]

Along with the API v2 obviously the structure of the 'load class' information has changed.

In PyViCareHeatPump.py the call is

@handleNotSupported
def getHoursLoadClass1(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.statistics")["properties"]["hoursLoadClassOne"]["value"]

but it should be now:

@handleNotSupported
def getHoursLoadClass1(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.statistics.load")["properties"]["hoursLoadClassOne"]["value"] 

This applies to all five load class requests.

The API v2 offers some more information (mainly compressor) than v1. The class 'compressor' in PyViCareHeatPump.py could be extended by (at least compressor load could be interesting):

@handleNotSupported
def getCompressorLoad(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.power")["properties"]["value"]["value"]

@handleNotSupported
def getCompressorInPressure(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.pressure.inlet")["properties"]["value"]["value"]

@handleNotSupported
def getCompressorInTemp(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.temperature.inlet")["properties"]["value"]["value"]

@handleNotSupported
def getCompressorOutTemp(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.temperature.outlet")["properties"]["value"]["value"]

@handleNotSupported
def getCompressorAmbientTemp(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.temperature.ambient")["properties"]["value"]["value"]

@handleNotSupported
def getCompressorOverheatTemp(self):
    return self.getProperty(f"heating.compressors.{self.compressor}.sensors.temperature.overheat")["properties"]["value"]["value"]

Now the fan load of the heatpump is provided as well. In class 'HeatingDevice' (PyViCareHeatingDevice.py) the fan load can be read out by:

@handleNotSupported
def getFanRotation(self):
    return self.getProperty("heating.primaryCircuit.sensors.rotation")["properties"]["value"]["value"]

I am not so familiar with the rules of GitHub so I wouldn't push these changes by myself, the risk to damage something is too high. Fell free to use the extensions or implement them here.

Pull-requests are always welcome, some of the data points are already implemented. Will see if I can do more. Also it's always appreciated if you provide a dump of your system to keep the test data up to date!

I noticed that PR #689 addresses most of the concerns raised here:

Load class path change: The PR implements a fallback mechanism that tries the new statistics.load path first, then falls back to the old statistics path for backward compatibility.

Compressor sensors: The PR adds getCompressorPower(), getCompressorInletPressure(), getCompressorInletTemperature(), getCompressorOutletTemperature(), and related methods.

Primary circuit rotation: Added as getPrimaryCircuitPumpRotation() - this works for both air/water heat pumps (fan speed) and ground/water pumps (brine pump speed).

Test data for a Vitocal 300-G with these features is already merged in #697.
