Install Netatmo

Just downloaded the newest Linux version to test WD as a replacement of WeeWX. I want to connect my Netatmo weatherstation. I can install the software and connect my Netatmo account to it. When I do so I get a new screen for Cron Netatmo. In this screen I cannot do anything. There are 4 fields that can be filled in, but there is no discription what to fill in. I also cannot find any information about this. The Login button doesn’t work as it doesn’t show anything. The other buttons give an error ({“error”:“invalid_grant”}) I’m now running Open Suse LEAP, but have the same problems on different distro’s like the latest Ubuntu LTS. What is the right way to install Netatmo under Linux?
