It appears that WeeWx is asking the console for an update every 5 minutes, but then sits on the data until the top and bottom of the hour. Because of my location, CWOP always wanted a 5 minute reporting interval. So did Wunderground.
I can't find anything that changes the time between reports that I haven't changed.
