I cannot find a field in you DTA file which would represent a flow value. Some DTAs have a direct flow field. Others have AIn / AnalogIn / AIn1 to calculate the flow from.
Does your heat pump has a flow sensor?

thank's for taking a look at it.
It has an flow sensor. On the website of the LWC i get values for the flowrate. The id of the flowrate is 0x0x230d20 in the website source.

Unfortunately, I can not find a field in your DTA file which could represent the flow. Maybe it is not stored in DTA? Do you see, at which port the flow sensor is connected to the controller? Usually it is AIn1.

At least I know that the pump is controlled by AO4.
At the website of the LWC I can't find an AIn1 anywhere.
AIN3 could be the flowrate, it's looking pretty similiar.
7.1 equals around 730l/min
7.5 equals around 790l/min
14.6 equals around 2200l/min
I compared AIN3 from DtaGui to logged values in fhem (captured from lwc website)

AIN3 could match to some flow values. However, I do not know, how to calculate the flow from the analog input. Do you know, what kind of flow sensor your heatpump is using? So far, I have only seen a Grundfoss VFS 5-100 and this sensor provides input signal between 0 and 5V. (Which is actually not the case here.)

i don't find any useful translation for the value. I think even if there is an translation formula, it doesn't realy make sence to build it in opendata. I'm afraid it's much to specific rated to my local Alpha Innotec LWC60.
edit: Is the value in opendta for AIN3 correct scaled? now at warmwater generation I have 2200l/min and 1.46V in the webinterface. Maybe the scale for opendta is 1:10? Then 5V could be max

csv is created by the dtagui .2
Can you please attach the DTA file (or send it via email to me).

not the one from the screenshot (downloaded it a few minutes ago)
