heating_base

[MaKi68]

Hello,
Where do I need to change the heating_base so that the value is used for NOAA and history reports?
I have changed the heating_base in
[StdReport]
     [[Defaults]]
         [[[Units]]]
             [[[[DegreeDays]]]]
                 heating_base = 20, degree_C
but this value is only used in the NOAA report and not in the history report (heatdeg).

I'm using weewx 5.0.2 pip on a Raspi5 with a Vantage Pro2.

Thanks in advance
LG Manfred

I'm familiar with heating degree days in the NOAA reports but what are the 'history reports' you refer to?

Like this:

All-time

Now i edited xtypes.py (/home/pi/weewx-venv/lib/python3.11/site-packages/weewx)

class AggregateHeatCool(XType):
    """Calculate heating and cooling degree-days."""

    # Default base temperature and unit type for heating and cooling degree days,
    # as a value tuple
    default_heatbase = (20.0, "degree_C", "group_temperature")

and it works for history-report.

For NOAA-report I have to edit it in weewx.conf.
