Thanks for the reply Don, I'll keep everyone updated on her eating habits. If I see her eat anything or even look at a cricket sideways I'm going to be ecstatic. I might just give her a bath in some water with a bit of the medicine in it just to rule out something fungal. I'll move the sensor as soon as I get home.
What's the perfect place for the sensor? Right now I have it kind of high up near a plant but not TOO near...
