first off, I did not investigate on this type of components deeply.

Anyhow, after reading the datasheet, this interesting BME280 from BOSCH seems to be defect, instead of having drifted.
Therefore I would suggest to simply replace that component, which is quite cheap.

Yes, it's clearly defect. What concerns me though is that I have 1 in 4
defect sensors. Sure, it could be just a fluke, but that it silently
failed is kind of concerning.
