Hi! I have a Zilla controller for my under tank heat mat. At 2am it stopped working and dropped to 79F before I caught it. I unplugged everything and unplugged it back in but nothing worked. I had to plug only my heat mat on and watch it. The controller is insanely inaccurate all of a sudden? I turned it all the way up to 100 on the controller but using another thermostat it read 87F. Does anyone know of a better one? I was thinking of the Jump Start MTPRTC Digital controller thermostat. I usually keep my girl at 88F on her hot side because she doesn't like anything lower or higher. She was okay for the night but she spent the night out of her hide unlike usual
