Hi,
If it is indeed the heatindex data that is incorrect you should be able to
use the new --calc-missing action in the wee_database utility to be
released with WeeWX v4 to re-calculate your heatindex data. That is of
course provided the obs used to calculate heatindex (outTemp and outHumidity)
Not sure if this is what you are after but:

Towards the bottom it gives the formula for 'apparent temperature' (which
the article states is called 'heat index' in the US).
