The official integration has been problematic from the beginning as both companies want the other company to create a full featured integration. There has been much discussion of this in the forum. I know @Diegocampy has been one of the people participating in those discussions.
So the linked services integration exists, but it’s not fullfeatured. It’s also limited to only a few devices. 
Here are some of the existing conversations about the brand:

How can we use Netatmo Weather Station in 2023? - #3 by Diegocampy
For those who have an Ifttt account, that integration has some triggers that the official smartthings integration does not, particularly for the WeatherStation, which would be relevant to this particular thread:

So this is another one of those situations where the first rule of home automation applies: “the model number matters.“
btw, Netatmo IS one of the companies participating in the smartthings early access matter program, so maybe we will see more integration in the future at least with the netatmo models that work with matter. But we will just have to wait and see.
