Right now inside & outside modules and rain gauges are supported.
It would be great to integrate the wind gauge.
I think it does not required too much work (just add the required value in SENSOR_TYPES inside sensor/netatmo.py), but the thing is that the developer of the Netatmo sensor has not got a wind gauge (and me too, I haven’t got one) so he can’t valid its development
I do have one 
And I’d like to help.
Just tell me how I can support you.
