I recently purchased and set up the O-1PST Kit, but the temperature readings seem to be way off. It always stays between 25–28°C, even though it should be much lower (around 20°C). Is there any way to calibrate or fix this?
Could you please apply the Standard Open Air Calibration and let me know if that improves the accuracy? You can do so from the ‘Advanced Settings’ menu:
Once there, please navigate to the temperature/RH tab:
