Tnx Ray,
i have found my problems (and resolved):
1st one was the DST, my system was always -1 h, after inserting the WU key everything was ok. The DST is done by WU?
2nd was with the Yesterday Rainfall/precipitation that are always 0, that was because i have set my location and AFTER put the WU key, everything was working except the Yesterday Rainfall/precipitation, i have re-set the location, now on map appears also the station near here, choose one and the Yesterday Rainfall/precipitation works now correctly.
Tnx
