Thermometer accuracy. Hi Im ,looking to purchase a 5 in 1 system through my local Costco store in Australia. I was wondering how accurate the temp reading would be if the outdoor thermometer is locate in the one unit that is required to be located in the open in full sun as outdoor temps are usually measured in shade. Previous units I have had have the temp gauge separate & I have located in a shade area, problem I see with this unit if placing in shade then I wont get a accurate rain reading. Does the thermometer adjust for open sun?
