Hello @Terdious,
I just launched with the image: terdious/gladys:netatmo-features-nrv-weather
I was able to log in with my credentials provided by the Netatmo site. I have a green message in Gladys confirming the connection: Gladys is connected to Netatmo (and I did accept the Netatmo message to allow access to all Netatmo devices (including the weather station)).
However, when I go to the Discovery section, no device is detected:
No Netatmo device was found. If you own a Netatmo Thermostat, have you completed all the steps in the documentation to register your devices on the Netatmo API?
An adjustment seems necessary to this error message; the thermostat contextualization is no longer accurate 
Do you see what might be causing this?
