i use these, one to control her hotspot and one to control the lamp for ambient air temperature -

they have temperature probes that read pretty exact temps. one is attached to the side of her tank (but not touching the glass) and the other one is buried in the substrate under her hot spot.

she does have 2 hides, one on her cool side and one in her hotspot.

she hasnt been wandering lately though, i think she may have just been hungrys, she hasnt been doing much sense she ate. but will try swapping out her log hide for the plastic one thats covered on 3 sides.
