Configuration

Nothing Fancy. Check out the config.json.example file.
You need to register your weather station to CWOP here: http://wxqa.com/SIGN-UP.html
After registering your weather station, you should get a callsign/name for your station. station.name value is the callsign.
station.pass value can be empty (Didn't try that way) but you can get your pass here: http://apps.magicbug.co.uk/passcode/
The latitude and longitude is a PITA :) They have to be in DDMM.MM format. Here is more on that: http://ember2ash.com/lat.htm (I have no plan to convert the regular DD-MM-SS to DDMM.MM format in the code. If you want to contribute, send me a pull request)

Usage

python /script/folder/cwop.py --config /path/to/config.json

If you use with no flags, it will expect config.json to be in the same folder as the script:

python /script/folder/cwop.py
