Need help....

First, you need to finish setup of Weather-Display to upload your testtags.php to your website – the one currently there contains demo data from my station from 01/27/2011. Use: https://saratoga-weather.org/wxtemplates/setup-WD.php as a guide on how to do that.

When it is working normally, your status page http://www.cedarridgewx.com/wxstatus.php will show “Current Data” and your site will show all of your current conditions. At present, only the realtime clientraw.txt file is being updated, not your testtags.php file.

You set the ‘refresh rate’ in two places. First, Weather-Display has to upload your clientraw.txt file at 10 second intervals. Use WD, Control Panel, Web Files/Realtime/WDL, Realtime Client FTP/AJAX TAB and set the interval to 10 seconds.
You’ve already set ajaxWDwx.js file to have

var reloadTime = 10000;       // reload AJAX conditions every 5 seconds (= 5000 ms)

so it will check every 10 seconds for an update.

For Oregon, try https://www.weather.gov/ and search for your city name. On that page with your forecast shown, there is a link near the bottom of the page for “Printable Forecast” it will look like

https://forecast.weather.gov/MapClick.php?lat=45.5118&lon=-122.6756

– copy that link and use it in the Settings.php for your forecast. Also on that page is a link to the Zone forecast… hover over that link and you’ll see an URL with ORZnnn in it… the ORZnnn is your Zone forecast code.
To find your County Zone code, go to https://alerts.weather.gov/cap/or.php?x=3 and look up your county … it will have an ORCmmm code… remember to use both ORZnnn and ORCmmm codes you discovered to configure the NWS alerts area in Settings.php

for 4 and 5 above, you just have to configure Weather-Display to upload testtags.php regularly (5 minute intervals).
