Just got my NetAtmo (http://www.netatmo.com/ WiFi Indoor and Outdoor weather station) and grabbed the opportunity to create an alfred workflow.
Special thanks goes out to PhilippeLt who wrote the Python that laid the basis for this workflow (https://github.com/philippelt/netatmo-api-python).
Grab it here: http://bit.ly/1gudid7
Import the workflow, edit the properties.py and type 'atmo', and your readings will appear.
In case you run into troubles, let me know!
Enjoy and let me know if you like it and how i can improve it!
Update 13/03/2014: added extra header field 'scope' for OAUTH2 security of NetAtmo.
