Hi
I've added [windGust] to the heatindex part of wxservices.py:
def calc_heatindex(self, data, data_type): # @UnusedVariable
data['heatindex'] = None
if 'outTemp' in data and 'outHumidity' in data:
data['heatindex'] = weewx.wxformulas.heatindexF(
data['outTemp'], data['outHumidity'], data['windSpeed']
*, data['windGust'])*
In wxformulas.py, I've added "G_mph" to represent the gust, as follows:
def heatindexF(T_F, R, V_mph*, G_mph*):
Have I done this correctly so that G_mph could now be used in a formula?
Thanks
