I have a remote temp/humidity sensor in the roost that trends the last 24 hours. last night it was like 15 degrees with 80% humidity out side, inside the roost it was 45% humidity and 42 degrees. the roost sensor is located on the outside wall across from the heating tube and element, so I am unsure if I may be seeing a colder reading then it really is in the roost. I am still tuning the adjustment for the heater as it has not got below 0 yet this year. I am going to move the senor in different spots in the roost to find out if I have a bigger temp differential then I am seeing.
