The temp sensor seems fine but only get a reading of -273c.
Pin 15 has a standing voltage of only 0.015v on it, I would have expected it to have internal Pull-Up resister inside the Xtreme to something like 3 or 5 volts?
I have previously installed 8 or 9 of these and all have worked fine but don’t have access to another to compare with at the moment
