there is now a netatmo driver for weewx:
https://github.com/matthewwall/weewx-netatmo
if you have a netatmo, and especially if you have the rain, wind, or additional sensors, please give it a try.
the netatmo provides indoor temperature, indoor humidity, indoor sound level, indoor CO2 level, pressure, outdoor temperature, and outdoor humidity. with the optional sensors it can also provide wind speed, wind direction, gust speed, gust direction, rainfall, one extra temperature, one extra humidity.
the driver has been tested on a basic netatmo configuration (base station and one t/h module).
the driver uses the netatmo.com api to collect data. my intent was to have a second mode in which the driver gets data directly from the netatmo. i've had this sort-of working (its complicated) using a packet capture approach since early 2015. unfortunately netatmo broke this approach when they started encrypting/obfuscating data sent by the netatmo station (as of firmware version 102, mid-2015).
so until we crack the obfuscation, we're left with download-data-from-netatmo.com approach.
at least its something.
