[Bug]: X3 Ultra - Inverter power always 0

[styriaman]

Describe the bug

HA displays always 0 as inverter power although the sum of inverter power1 to inverter power3 is not equal to 0
I haven't tried it yet, but it will probably also have negative effects on Remote Control, where ‘houseload_nett’ is also calculated from it

Perhaps it can be calculated in the 1st step from the sum of inverter power 1 to 3

Possible working changes in plugin_solay.py:

Add

def value_function_inverter_power_g5(initval, descr, datadict):
return (
datadict.get("inverter_power_l1", 0)
+ datadict.get("inverter_power_l2", 0)
+ datadict.get("inverter_power_l3", 0)
)

and

SolaXModbusSensorEntityDescription(
name="Inverter Power",
key="inverter_power",
value_function=value_function_inverter_power_g5,
native_unit_of_measurement=UnitOfPower.WATT,
device_class=SensorDeviceClass.POWER,
state_class=SensorStateClass.MEASUREMENT,
allowedtypes=AC | HYBRID | GEN5,
),

and remove | GEN5 from the register based "Inverter Power" EntityDescription

Enjoy
