Hello, I’m using BME280 sensor for my project. temperature & humidity readings are correct but pressure reading is too high. I used another sensor for getting pressure which returns normal reading like 1000hpa while BME280 returns 1180hpa!! it’s too high. I am using python library. and I read the document. I set the pressure_oversample value according to the example written on document(https://qwiic-bme280-py.readthedocs.io/ … t/ex4.html) but still getting high value. Please help me if you have any idea. 
Did you ever get this resolved? I’m having the same issue - Running their sample code, I’m getting a pressure reading of 142920, which I believe equates to a barometer pressure of 42.20… impossibly high! I’ve tried various oversample settings with no difference. Very dissapointing. The temperature value seems reasonable, but the humidity seems low. I’m wondering if somehow when the board was built, the sensor hole in the chip got clogged… maybe with solder??
Nevermind… Fixed it… Sparkfun’s software is just broken. I tried Adafruit’s code, and it works fine. Really disspointed in the QC from Sparkfun recently.
I apologize for the inconvenience. I would suggest that you should file a GitHub Issue so our engineers have better visibility of the issue and can try to replicate your circumstances.
