See also another discussion about Netatmo, specifically about the weather station, but mentioning the same issues of lost connection / data transfer. This very annoying issue has still not been solved.
Short summerary from this other discussion:
The error seems to occur at least when multiple Homey systems are used (Pro and Premium, or two devices).
A workaround for who doesn’t have too may flows (such as I have), is to use the Bticino third party app instead of the official Netatmo app. I am still waiting for a solution.
