In the process of checking all of my Rainmeter packages to ensure they are functioning properly... this will take some time, but I hope to have this done by the end of Jan 2026!
** Updated APIKey value to correct all weather skins **
APIKey=71f92ea9dd2f4790b92ea9dd2f779061
To correct any TWC weather skin, locate 'WeatherComJSONVariables.inc' file (usually in the '@@Resources' folder).
Open that file in your text editor and locate the line APIKey=21d8a80b3d6b444998a80b3d6b1449d3 and change the line
so it is APIKey=71f92ea9dd2f4790b92ea9dd2f779061
Save the file and click Refresh All in Rainmeter or restart the program.
As of August 25, 2023 it appears people in some countries (Russia has been mentioned) are not able to access Weather.com
I do not know if this is a permanent issue, but it may be why some people are having trouble with weather skins.
