Another attempt (I did not increment the version, but re-copy the code)
[UPDATED] V3.0.4 03/24/2019
Further reduction on the character limit for myTile. This was primarily though renaming the icons to very short names. Because of this you will need to re-copy the icons from my GitHub repository (GitHub - Scottma61/WeatherIcons: WeatherIcons for Hubitat Drivers) to your webserver to get the new named icons.
If the MyTile exceeds 1,024 characters (including file paths to icons and HTML formatting) then it will attempt to display with no icons and no formatting. If it is still too long, it will truncate the unformatted string to 1,024 characters.
If this still does not work, then I will need much more detailed information to continue to try to help .... logs, screen shots, etc.... It is working on my setup so I cannot duplicate the 'no go'. I can only assume that the new Dashboard 2.0 maximum character length of 1,024 is being exceeded. I attempted to prevent that from happening.
