Thank you very much @glhopital.
Yes, I have, in two ways:
- By clicking on the Scan button in the Add new thing/Netatmo binding screen: in a few seconds the scroll bar reaches 100% but no devices are detected.
- By running the following command in the Karaf openHAB console (assuming it is the correct one; I have inferred the binding ID from the source code):
openhab> openhab:discovery start netatmo openhab>
This is confirmed by the Netatmo API documentation.
You definitely know better than me, but this post (and the following two) imply that this kind of thermostat cannot be controlled in any other ways than through the cloud. Since you have considered discovery as an option, I am assuming that currently supported NA* devices are not restricted to this cloud-managed-only architecture.
So, in case this model is really still unsupported (I was also considering the humble option of contributing but, to be honest, I will hardly be able to 
) and considering the possible similarity of the Netatmo API with the former Legrand one for which the BTicinoSmarther binding exists, do you think that future development may likely consider this improvement?
The most I can think of in the meantime is to resort to less elegant workarounds (scripting, HTTP binding, etc.) to access the thermostat data.
