The WXSim forecast upload is fairly simple. If you’re running Weather Display software then you can just use the built-in FTP function.
In WD, go to Control Panel > FTP & Connections > General FTP Functions. Then press the “Choose the file” button and navigate to where WXSim files are and you’re looking for one called “plaintext.txt”.
Click on “Select this file” and you should see the file address appear in the Local filename window to the right and the “plaintext.txt” in the “Remote Filename” window.
Now select the upload times which need to be just after your forecast run. Make sure the switch under “save changes now” button is ON and then click the button above to save your settings.
You can test the uploads by clicking on the “Test” button.
As for displaying the forecasts, you can just add the plaintext.txt file to a web page, or use the plaintext script from Saratoga Weather, instructions on the linked page.
