Meter description

Hi,

I got a new heat meter with wmbus which is not supported by wmbusmeters.
It's from Meßtechnik the type HMM-2.
Datasheet Meßtechnik

The Meter seems to be a relabeled type from BMT / BMETERS acc. the output of the HA addon:
(meter) Heizung: meter detection did not match the selected driver c5isf! correct driver is: unknown! (meter) Not printing this warning again for id: 05040538 mfct: (BMT) BMETERS, Italy (0x9b4) type: Heat/Cooling load meter (0x0d) ver: 0x1a

The driver c5isf returns the best result for me.

The original type could be BMT / BMETERS HYDROCAL-M4
Datasheet BMT / BMETERS

Hi,
Support implemented, please test.

[killer0071234]

Thanks for the implementation!
It works like a charm!

I added a own file hydrocalm3.json in mqtt_discovery to get my sensors in HA (see Add mqtt discovery files for hydrocalm3)
