The "weewx way" would be to write a simple service that binds to the
NEW_ARCHIVE_RECORD events and replaces the value of heatindex with the
results of your calculation. Something like (NOT TESTED):
from weewx.engine import StdService
class MyHeatIndex(StdService):
def __init__(self, engine, config_dict):
# Pass the initialization information on to my superclass:
super(MyHeatIndex, self).__init__(engine, config_dict)
self.bind(weewx.NEW_ARCHIVE_RECORD, self.new_archive_record)
def new_archive_record(self, record):
record['heatindex'] = my_fancy_formula(record['windGust'],
record['outTemp'], ........)
Run the service *after* StdWXCalculate.
See the section *Creating a new service
<http://weewx.com/docs/customizing.htm#Adding_a_service>* for details.
