after update to new version and restarting in steelseries wind run is always zero. wind speed and gust calculating as before.

See issue #737.

Solution is to change 'prefer_hardware' to 'software' for windrun. While you're in there, you might as well change ET too. When you're done, it will look something like:

[StdWXCalculate]
   
    [[Calculations]]
        # How to calculate derived quantities.  Possible values are:
        #  hardware        - use the value provided by hardware
        #  software        - use the value calculated by weewx
        #  prefer_hardware - use value provide by hardware if available,
        #                      otherwise use value calculated by weewx
       
        pressure = prefer_hardware
        altimeter = prefer_hardware
        appTemp = prefer_hardware
        barometer = prefer_hardware
        cloudbase = prefer_hardware
        dewpoint = prefer_hardware
        ET = software
        heatindex = prefer_hardware
        humidex = prefer_hardware
        inDewpoint = prefer_hardware
        maxSolarRad = prefer_hardware
        rainRate = prefer_hardware
        windchill = prefer_hardware
        windrun = software

widmeter works well now  with windrun = prefer_hardware and , record[obs_type] = self[obs_type].sum if self[obs_type].count else None , in accum.py.  thank you!

updating.

after 2 days suddenly windmeter again always zero on steelseries page.

i suspicius that happens only on steelseries ,because in test page with $windrun.day.sum  , windrun updating well every 5 minutes , and the  steelseries odometer remains steel in zero.

with windrun = software and   record[obs_type] = self[obs_type].sum if self[obs_type].count else None , in accum.py
