Yes I didn't see alot of reptile related uses for the thermostat, however the incubator that we have has an inkbird thermostat like the one I described in the op and it works amazingly, I really liked the sleek look of it and so I wanted to incorporate that in our new snake enclosure builds, and as far as wiring and calibration of the thermostat, it seems to me that it is very dialed in, it is a proportional thermostat, I believe you could be correct tho about it being the thermostat because there are settings for the thermostats proportional controller, which by default it is set to .4 seconds, so every .4 seconds it's supposed to control the heat source, which I can change to make it basically whatever I want but at .4 seconds the hot sides reading 88-89 and cool side is 79-80 with a pretty decent overall ambient humidity of 60-80
I went with the faqs on reptile basics, on their website it said a 40watt had good results in a 4x2x2 enclosure but I can see why I may need a bigger one for sure
