I too was using both ActionTiles and the “custom weather tile” from codebuffer’s weather_action_tiles . I had been using the custom weather tile for over a year, but lost the long custom URL when ActionTiles went down. I was using both the wide & narrow versions of the weather tile on two different panels.
I looked at SharpTool’s “Weather Tile - Open Weather - Current and Forecast custom tile” too, and although it very similar, I do like that the CodeBuffer has a few things SharpTool’s weather tile does not appear to include: Today’s High&Low forecasted temps on the main screen, the current wind direction, UV index, and the ability to see the upcoming forecast just by tapping it. This gif is from codebuffer’s weather_action_tiles website showing the behavior.

I went back to codebuffer’s weather_action_tiles and it was easy enough to step through the process to rebuild the URL, codebuffer’s system remembered the inputs I made before.
Besides being able to set the background and text colors to anything you want, I saw that codebuffer has included the standard Sharptools theme colors for ease of use.
I have not yet decided which direction I will be going in regards to a new panel provider, but I will definately be keeping CodeBuffer’s weather tile in mind.
