Note that I had solved similar issues by changing options in WXSIMATE. Customize → ‘Archived data time settings’ → ‘Use 0 minutes before hour’ instead of ’ Use 5 minutes before hour’.
It has been vague but a similar reference has been made in the forums. It seems the 3in1 scripts want the details on the hour/half-hour only.
I have not had a chance to research why, but it is on my list (to help out Henkka since I am in the US)
