I’m using a Netatmo Weather Station consisting of an indoor and outdoor module, a rain gauge and an aenometer in conjunction with OpenSprinkler DC 3.1. The rain gauge can’t be used as a standalone product. The Netatmo Weather Station sends encrypted weather data peridiocally to netatmo servers. The encryption blocks end-users from accessing the data. You have to use the netatmo API to obtain the data from the netatmo servers.
The corresponding setup of how to connect a Personal Weather Station to a Local Weather Service is described here: OpenSprinkler Weather Service.
