Wind Speed error on WD every morning at 00:30

Running an Ultimeter 2100 WS here and Latest version of WD 10.37S45. WD reports a wind gust at 12:30 AM usually 21.6 MPH even though there is no wind or it is less at that time. Just noticed this occuring recently. It is not always 21.6, but it is there regardless. Anyone else notice this occuring? Also notice that the recorded gust at 12:30 is not shown on the WD graph or on the instrument control panel either.

I’ve updated to the latest version. Will see if it helps in the morning.

are you using the complete record mode?
if so , make sure the time on the weather station console matches the pc time

Darned Daylight Savings time… #-o Thanks Brian! Cheers! Keep up the good work.
