My 5 in 1 pro runs about 5 - 6 degrees higher than my other reference temperature sensor at night. During the day as soon as the sun comes up they both read the same. I also checked WU for units in my area, and they are all lower at night than mine.
Model 06037. I have it mounted 6 ft high in an open area except for a 6 "block wall that is 2 ft below below the station. I haven't paid attention to the humidly. I am comparing it to a Pro Accuracy Indoor Temperature and Humidity Monitor that is mounted in open air under my patio cover, to protect from weather.
