No problem, By the way the probe in the thermometer only measures temperature. The Unit itself mesures humidity. So you have to stick the unit inside too.

I would put the probe under the warm hide and the unit in the cold side. In itself, the unit has a thermometer and also measures humidity, the probe is a secondary thermometer. So you get warm side temperatures from the probe, Cold side temps from the Unit and also humidity. All 3 measurements in 1.
