I understand that the readings go straight to the hub, then to wunderground. Unfortunately, if I can't get my calibrated readings to post on wunderground, it doesn't do me any good. Too many people rely on me posting accurate readings to WU. In the hot Texas sun, my unit shows as much as 7 to 10 degrees too high, and yes, the fan on the unit is working. Maybe the programers can figure out a way to get the readings from the Dashboard to go to the hub. It's too bad we don't have a choice in staying with the old system versus the new one, therefore, now is the right time to look into getting a Davis weather system, which is more expensive, but also more reliable and accurate.
