actually it should be working already with the latest wdmysql version update
Nope, still not working.
All the missing data is being replaced with 0 (zeros).
Fields missing from the old data files based on the standard WD mysql fields are :-
average_windspeed, gust_windspeed, daily_rainfall, monthly_rainfall, yearly_rainfall,indoor_temperature, indoor_humidity, extra_temperature_sensor_2, extra_temperature_sensor_3, extra_temperature_sensor_4, extra_temperature_sensor_5, extra_temperature_sensor_6, actual_solar_reading, max_daily_temperature, min_daily_temperature, icon_type, current_weather_desc, barometer_trend_last_hour, max_gust_current_day, max_humidex, min_humidex, max_windchill, min_windchill, davis_vp_uv, max_heat_index, min_heat_index, max_average_windspeed_day
There are other items such as the WMR station batteries and the like which I don't have, but I'm guessing they don't work either.
Not much good importing old data if all you have is "0" as the data stored.
From my perspective I haven't done anything with mysql for my weather station because I can not make it worthwhile, as you have no historical data to go with. Unless of course you set up mysql from day one with WD, and most people don't think about it when they first setup.
