Hi, Further to what Tom said, I have been working on an 'wee_import' utility for weewx under issue 97 <https://github.com/weewx/weewx/issues/97>. Initially I included import from a single CSV file and a WeatherUnderground PWS and have recently added support for importing from Cumulus monthly log files (which are really just a series of CSV files). From your description your VWS data sounds very similar to the Cumulus monhtly logs; its just a bunch of CSV files albeit covering a different time period and I expect different format. If you care to give me the format of the VWS files I expect it will be a simple matter to extend wee_import to work with the VWS data.
1) The VWS data does not have dewpoint, heatindex or windgust10 values. Do > I need to add these values to the archive table as I'm inputting records? > wee_import has an option to automatically calculate and include any missing *derived* obs, so this would take care of your missing dewpoint and heatindex and possibly a number of others too (windchill and rainrate if they are missing), depending on your source data. It will also take care of any missing pressures provided you have one of them and know what it is (barometer, pressure or altimeter). > 3) The VWS had an archive rate of 15 minutes. Can I switch to 5 minutes > once I switch over to weewx, or will this cause problems with historical > averages? > Since I am working on the fix Tom mentioned I would only suggest that you make may life easier for yourself if you can do the cutover from 15 to 5 minutes on a midnight boundary (ie your last 15 min record is timestamped 00:00, your first 5 minute record is 00:05). > 5) any other gotchas in doing a conversion to weewx? > Not really a gotcha (you will soon notice if your daily sumamries are incomplete after you import data into the archive) but if you end up manually importing data into the archive you will need drop then rebuild you daily summaries <http://weewx.com/docs/customizing.htm#Dropping_and_rebuilding_the_daily_summaries> using the `wee_database` utility. wee_import will take care of this though.
