Topic: RELEASE: PyWeather 0.8.2 for Davis Vantage Pro + WeatherUnderground

[wolfdown]

PyWeather is Python module for accessing Davis Vantage Pro/Pro2 serial weather data. It also supports data upload to the WeatherUnderground. Included in the package is a working script for collecting and reporting data I am using on my own weather station.

You can find the source code and more information here: http://github.com/cmcginty/PyWeather

Additional Background:

I've spend the last few months improving the last official PyWeather 0.7, which was some years ago. At the time I could not find any simple Linux-based drivers for the Davis Vantage Pro weather station, except PyWeather. Since then I've re-written the entire Davis interface module. With this release it is now possible to configure and read Archive Record data fields, and a number of bugs were fix. The Python code has been tested on Ubuntu 9.10, but it can likely easily be modified to support Windows or Apple OS.

If anyone finds this software useful, I'd love to hear from you.

How about support for uploading to PWSweather.com? 

[wolfdown]

Shouldn't be a problem. I'll take a look at it soon.

I couldn't find any data regarding the reporting format. If you have the details, this would really help me add support for the site.

If you fill out a support request at http://www.pwsweather.com/support.php it'll be e-mailed to you.

WARNING! I tried this software, and the first thing it does is WIPE ALL THE ARCHIVE DATA off the Weather Station. This is really dumb and it caught me out. I'm like - where has my data gone, so I looked into the code a bit more, and it actually does it ON PURPOSE, WITHOUT WARNING! so nice try, but, *sigh*

  What you said is correct. The record clear speeds up the system startup. The assumption was that archived data is stored online. Sorry you had to be the first one to discover this "feature".

I will disable the format command for an alternative solution.

Are you just using the device memory for the LCD graphs or is there some other reason? Is it a problem that the software change the archive interval?
