Hi, These sorts of template/Cheetah errors can be difficult to pinpoint and time consuming to track down. That being said the error message gives us a couple of clues. The error message indicates there is a an expression somewhere in the gauge-data.txt.tmpl that is trying to calculate the difference between a floating point number and the python value None. The None value is likely the result of a 'missing' observation value, most likely windSpeed or dewpoint. The puzzling part is that the gauge-data.txt.tmpl template has been hardened over a number of iterations and the current version should be immune to such errors.
Could you confirm which version of gauge-data.txt.tmpl you are using; either provide a link to the file/extension you are using or post the actual gauge-data.txt.tmpl from you system. Also is your site internet accessible? A link would help in determining which observation is returning the None value.
