I purchased the 06007rm & 06004rm setup a week ago. I live in Dallas/Fort Worth area. The 5in1 sensor is on a pole out in the yard about 6 feet off the ground. Every morning at 6:00am when I look at the display the humidity is 99%. After the sun hits the 5in1 sensor the humidity starts to decrease. I have 3 other temperature/humidity sensors (ranging from 20% to 50% over the last week) and they have been close to our local airport and three other weather reporting stations (within 2 miles of me). It seems that the 5in1 sensor has a leak that is allowing condensation to drip/collect on the sensor or the system has a design flaw.
