PyVantagePro 0.3

Communication tools for the Davis VantagePro2 devices

PyVantagePro is a python project which aims to make the communication with weather stations Davis VantagePro2 easier and funnier…i.e. more Pythonic.

The main feature of this project is to get data automatically. In order to do so, it uses the basic methods get_archives() (to get archive data) and get_current_data() (to get real-time data).

About configuration, it only uses gettime() and settime() because we are assuming that stations are already configured.

Note: PyVantagePro uses the PyLink lib, offers a universal communication interface with File-Like API.

Examples

>>> from pyvantagepro import VantagePro2
>>>
>>> device = VantagePro2('tcp:host-ip:port')
>>> device.gettime()
2012-06-13 16:44:56
>>> data = device.get_current_data()
>>> data['TempIn']
87.1
>>> data.raw
4C 4F 4F ... 0D E6 3B
>>> data.filter(('TempIn', 'TempOut', 'SunRise', 'SunSet')).to_csv()
SunRise,SunSet,TempIn,TempOut
03:50,19:25,87.3,71.5
