I go off 2 temps, the hot spot which like i said is either from the top of the warm hide if using a CHE or RHP and the glass temp or floor temp under the substrate if using a UTH or heat tape. The second temp i pay attention to is the overall ambient temp which is the air in the whole cage. I keep that temp at 77-79F depending on the room temp. This is because a snake needs to cool down and warm up. Being stuck in either only will lead to health issues.

And this was meant for the OP, not Calm
Yup I get my ambient with my Acurite thermometer Unit mounted on the cool side and then its probe is run out the back and over into the Hot Side.
That Thread on how to set up a PVC is good as Gold. There is one for a Glass Tank too if I remember correctly.
