Your pwsWD/wuCSV_Replace/
=> I am not familiar with that folder and do not know were it comes from.
=> I can not find that name in any of my recent dashboard or Leuven scripts.
=> checking the contents https://armon.com/pwsWD/wuCSV_Replace/ all files are dated October 24
==> it seems an older copy of the https://armon.com/pwsWD/wudata/ folder which has today time-stamps.
pwsWD/wsreports/
=> Leuven script, stand-alone version.
=> the supported version tailored to dashboard => wureports/
=> This version is not correctly adapted to the new MITM script it uses pwsWD/WXDailyHistory.php
=> discard this folder and install the correct version from External scripts which use WeatherUnderground .CSV data
=================================
The folders most often used in correct installations:
pwsWD/wudata/
=> that folder is located inside the pwsWD/ folder.
=> should be copied to the new version-folder when updating the dashboard
=> data is needed for the graphs and can be used for the extra wu-scripts outside the pwsWD/ folder
=> data is generated by the MITM script pwsWD/PWS_DailyHistory.php by using API to load data and storing that data for general use
=> the folder should contain each years WU data in PHP-array .arr files which are updatable by a separate script _wu_upd.php
=> the .arr files are the main data storage files used to generate the .CSV data as used by all other scripts.
=> there should be one file named YOURWUID-metric-YYYY.arr for every year (YYYY) you were uploading to WU after the year 2008 (older data is lost from the WU data base)
=> the pwsWD/wudata/ folder can also contain cached versions of .CSV files in extra folders/subfolders with name YYYY/
==> year and month files inside the yearly folders can be discarded at any time
==> if daily .CSV files are removed the data need to be retrieved from WU again as that datas is not stored in the .arr data storage
wuhistory/
=> outside dashboard folder
=> dashboard version of my Leuven WU history script using the old .CSV format and supporting day, month, year and custom periods
=> it should not have any cached data
wureports/
=> outside dashboard folder
=> dashboard version of my Leuven WU table/report script using the old .CSV format, only uses yearly files
=> wureports/wudata/ cache folder to speed up the data retrieval of yearly files
==> the cache folder can be emptied if the main wudata/ folder with the .arr afiles is updated.
Hope this helps,
Wim
