Solar water heating collectors

Please, would it be possible to add collectors for water heating to the energy card? Integration would also need to be done, where the input values ​​would be the flow and temperatures at the inlet and outlet, and the result would be energy in Kw/h

Does your solar water heater system have an API?

I am interested in just such an implementation. For my case I use a Viessmann hot water solar system. I can get the solar energy yield directly from the heating control via the ViCare API.
I have already integrated this into the energy dashboard today. However, the yield is of course added to the electrical consumption, which is of course not correct.

I am interested too. My system is a buderus sm10 and I am reading the values via ems-esp. Intigration was pretty easy, but it is not a electrical consumption but for warm water.
