myatmo does not start - how can I fix that?

Solution

If myatmo does not start, but may crash after starting on your device, it almost always helps to delete the app from the device. Then restart the device once and reinstall myatmo.

The cause of such a problem is usually an authentication problem with the netatmo data server. Reinstalling myatmo deletes temporary authentication IDs and renegotiates them after reinstalling with the netatmo data server.
