Hi,
Thanks for the information.
From your Excel file, the temperature calculation has correct result, while the pressure calculation has wrong result. It seems like both BMP280 and BME280 sensors on the tiny PCBs have issues. If you want, you can ship these two PCBs to your local Bosch support and then we can do failure analysis on these two sensors.
In addition, BMP280 has been end of life. Please switch to BMP390 or the new BMP581 for your projects.
Thanks.
