Question about Netatmo Smart door and window sensors

From my point of view, it doesn't work (yet?). In any case, it is not currently described anywhere and the tags could not be found in the Home app.

I had also tried this, but it doesn't work. However, the Netatmo products can be controlled on the mobile phone via an app. They are very good products and can certainly be recommended.

I also thought that I could create automations in the HomeKit app, for example. But they are nowhere to be seen in the app. So unusable for me!
