Thanks. All our computers at my place are running linux, and have for almost a decade. I set up pywws on the HTPC I keep in the living room. Everything was fairly easy once I figured out what you are supposed to do. Like a number of things in the linux world, the documentation leaves something to be desired.
The pywws site does the first part right - showing you how to install and setup the software, but then they fail in presenting the next steps. After it is setup, they need to cover weather.ini in detail, then point out that the graphics templates are fed to plot(), then cover plot(). After that, they need to point out that the text templates are covered under the templates heading, and go through that. Finish up the docs with a section on conversions, showing how to handle some of the more common conversions in both the graphics and text templates.
My brother and I got it going in an hour or two. The web-side template was also handy. Now I can take some time, adjust the range on various plots, maybe add a few more templates for specific things, and adjust the look of the page. This forum was helpful in this as I found threads on conversions.
