I had the same problem more than a year ago and was searching for a solution. At the end I had to take down my website for few months and take the time to find a reasonable solution without killing the Cat.
There is one solution that worked out for me since Stu wrote the API link to Meteotemplate (
www.meteotemplate.com). Through this there is not need for SFTP because WeatherCat sends the data directly to Meteotemplate.
This resolved another issue for me i.e. the fact that although Ken's Saratoga template is great I didn't have the time (or the brains) to take care of regular updates and add-ons.
I think that few WeatherCat users are also using Meteotemplate and can give an opinion about it. As far as I am concerned the template is providing a myriad of functions that are overwhelming for many. On the other hand there are many ideas and solutions for individual regions and countries that open a new world of possibilities for weather lovers.
Maybe this helps.
