I am pretty sure they work together but just wanted to check with some of you who may pair them. I want to get the Herpstat 2 and use one probe for my BP rack and the other for my beardie cage. I like how I have seen people mention that they use the ramp up feature of the herpstat and that is what I would like to do for my beardies. Have the CHE kick on in the morning but warm up slowly. I will use one of my hydrofarm thermostats that I will no longer be using to regulate the UTH I have under the floor tile bottom of the cage at night.
