Just a quick heads up for those CS'ers running heatsnob with a laptop (plugged into mains power) that may encounter an alert that the thermocouple is shorted to ground.

The chances are the laptop itself is not properly grounded via the adaptor.

Big thank you to Andy for providing this answer on a Sunday afternoon whilst I was trying to sort out where the problem was.

Solution: Run the laptop on battery power and the issue did not reappear, else use a different fuse circuit.

Thanks Andy .... genius ...
