Just to add this question on for when I can get the CHE off the dimmer and on a proper thermostat- where exactly would the probe go for that? I've been measuring the space the area hits with my temp gun for now and adjusting the dimmer based on that for the time being, but I know the thermostat probe won't measure in the same manner once I get that. I've only found maybe 2 threads that even go into this for BPs- almost all just said switch to UTHs but didn't really detail how to set things up if you need both. The other that did talk about it varied from putting the probe on the substrate, to partway down the enclosure wall, to on top of a hide, or to right on the top of the tank right under the CHE. So admittedly 100% lost there as I can't even figure out a proper middle ground because each bit of placement advice is drastically different. The only consistent thing was making sure the probe is secure but that I knew already.
