      I'm not sure how your physical test was setup. In the past I've found the best test was to put the sensors in a cardboard box, maybe 6x6x8 with the sensors on a plastic platform (an old food container), close it and let it sit for some hours in an area away from heat / cool vents etc. Is the host board the same for both sensors? For humidity you can put both in a plastic bag with a saturated solution of salt and water. Let sit for a few days. The humidity inside the bag will be almost exactly 75%. Becomes a cheap and dirty "reference" There has been reports that sampling too frequently will cause internal heating to a small degree. At what rate are you sampling the device? These suggestions are not to say what you see is not part to part variation.

      Hi @Guillermo-Schimmel, I know it's closed but just noticed this issue, you most probably had STP (Spanning Tree Protocol) enabled on that port, which is normal for ent switch, and while it waits for a loop it blocks trafic from that port. Disabling that feature should solve this problem.
