Power consumption heat pumps

[Toschi57]

Hi Oischinger,

I created also a request in the home assistant forum. Not sure which place is better.

It would be very great if you can add the power consumption values for heat pumps.

In pyvicare it is implenented
openviess/PyViCare@5b81132

By the way, great work and a big Thank.

+5 Ditto please!
Although the gas sensor that appears seems to be doing the right thing just called the wrong name.
Thanks so much for your work

At least I wrote some tests that indicate so.

However the sensor name is not good. I'll change it in an upcoming release

-        name="Energy consumption of hot water gas heating current month",
+        name="Energy consumption of hot water heating current month",
