Good point. Since I turned off other parts, I'm surprised I didn't think of that before the /dev/null idea. Are there any calculations performed by the reports prior to populating the database that would be missing? > Having the reports done by a separate program running on a VM is a little > more complicated. > > The simplest option is to use wee_reports to do the report generation.

I really miss the wind speed and direction radial graph it provides (see dirplot.gif <http://www.canterbury-city-2000.co.uk/canterbury/canterbury/dirplot.gif> and dirplot.gif <http://jaxweather.net/WeatherImages/WD/dirplot.gif>). At a glance I could quickly understand the wind direction trends (since it's based on a compass, it's easier/faster than daywinddir or daywindvec for me) and speed (it uses many steps to transition from white to pink to red as the wind speed increases). This has been mentioned before (see this <https://groups.google.com/d/msg/weewx-user/0hGKjHwD3J0/uTeuqLr-J3gJ>), but I haven't found anything else about it. I do remember seeing it on a weewx wish list sometime back but that disappeared. I found something here <https://bitbucket.org/ozgreg/weewx-wd/wiki/Advanced%20Customising> but I haven't tried it or figured out if it yields what I want. > Those are the choices that come off the top of my head. > Such quick, quality help for my question makes me wonder if you have thoughts about my wish?
