@Fozi Sorry for being late to follow up. My error is as follows:
When I start up MM2, it shows that the module is loading. A spinning cycle shows in the middle of the screen. However, no graphics are shown - just the spinning cycle icon. I have double and triple checked the config.js file, and all seems correct there. No errors show up in the logs on the npm or in my web browser.

Any idea what could be wrong?

@Fozi I am using that exact same fork - but without luck unfortunately. Are you using the module, and can you confirm that it works for you currently?

Does anyone have any news on this? It seems as if the data structure in the Netatmo API has changed, making the current MM2-modules unusable? Or is it just problems on my end?

Thanks.
