Apologies for the thread hijack, @brewdexta what are you using to sense and log that data? Looks quite impressive!Both cars are showing -6 but the outside temp gauge behind the workshop was only -3.25, possibly as its near the building and keeps a bit warmer. The workshop pellet boiler and fan coil units are doing their stuff and keeping the temp above the dew point so no condensation on the tools. I cocked it up last year by about 1.5c as I had raised the sensor closer to the workshop ceiling and had to derust some newly cleaned up cast iron saw benches and planer/thicknesser.
