Dear @Anders_Hartmann if usr/psswd is correct it should work. Problems with floors are now solved.
I really don’t know whats happening. What you can do (if you want) is to add me as a guest in melcloud app and I can try by myself if I can add your device on my homey or do a couple of tests to investigate which problem is happening…
If you want me invite me at … in melcloud app.
