If you really want to do this, you would be better off writing a simple
WeeWX service, rather than trying to squeeze it into StdCalibrate. It's
really pretty simple. Something like this (NOT TESTED):
*File user/temperature_fix.py:*
import datetime
import weewx
from weewx.engine import StdService
def fix_temp(record):
hour =
int(datetime.datetime.utcfromtimestamp(record['dateTime']).strftime("%H"))
if record['outTemp'] > record['extraTemp1] + 4 and 16 < hour < 20:
record['outTemp'] = record['extraTemp1']
class FixMyTemperature(StdService):
"""Service that switches between temperature sensors"""
def __init__(self, engine, config_dict):
super(FixMyTemperature, self).__init__(engine, config_dict)
self.bind(weewx.NEW_LOOP_PACKET, self.new_loop_packet)
self.bind(weewx.NEW_ARCHIVE_RECORD, self.new_archive_record)
def new_loop_packet(self, event):
fix_temp(event.packet)
def new_archive_record(self, event):
fix_temp(event.record)
Add this new service to the end of the process_services:
process_services = weewx.engine.StdConvert,
weewx.engine.StdCalibrate, weewx.engine.StdQC,
weewx.wxservices.StdWXCalculate, user.temperature_fix.FixMyTemperature
But, do you really want to do this? There is no substitute for a properly
calibrated and sited instrument.
