For the accurite, the body of the device needs to be inside the enclosure in order to read the humidity, the probe only reads temperature.

Temperatures I read with a temp gun entirely. The thermostat determines the temperature of my heating element, the temp gun gives me temperatures for the substrate. I have an accurite on my wall for measuring air temperature in the room.

Humidity is measured inside tubs by the good/bad method. It's good if sheds are clean and there isn't condensation. It's bad if sheds are bad or there is condensation.
