Using Weatherlink.com as a data source there are no uploads needed and no config program for the template.
You should edit the lines 44-48 in wsUserSettings.php where you have to enter your ID and password for Weatherlink.com.
# for weatherlink.com users -------------------- #$SITE['WXsoftware'] = 'DW'; // ##### Davis WeatherLink.Com ONLY uncomment after setting the id and password $SITE['wlink_key'] = 'xyz'; // ##### Your weatherlink.com user id $SITE['wlink_pw'] = 'xyz'; // ##### and password.
Remove the comment mark as your weatherprogram is coded internaly as 'DW' for “Davis Weatherlink.com”. Set the wlink_key to your userid for the weatherlink.com website and wlink_pw to your password for that site. it should look like
$SITE['WXsoftware'] = 'DW'; // ##### Davis WeatherLink.Com ONLY uncomment after setting the id and password $SITE['wlink_key'] = 'herent'; // ##### Your weatherlink.com user id $SITE['wlink_pw'] = '123456'; // ##### and password.
There are no “yesterday' values registred by WL.com. So to get those values a small script should be run every day around 23.45 but before 00:00
The script that has to be run is: www.yourwebdsite.com/weather27/yesterday.php
The easiest way to do that is to use cron http://en.wikipedia.org/wiki/Cron
