Mine's a hypo as well! I'm going to have a hard time not handling or checking in on him for a whole week!
I'm using this thermometer/hygrometer from Acurite:
I don't think it's faulty as it was giving me other readings fine before, e.g. 50% outside of the enclosure. It does read high when it's touching the walls of the tub, so I've tried to change up its placement a few times, so far it's holding steady in the 80s![]()
