  • I can confirm, that readings seems to be high compared to other I2C sensors. Since all available BME280 libraries give similar results i assume, there could be a misinterpretation of calibration values or a not yet discovered problem with the datasheet. I set up a small test on 3.3V bus with readings all 15s.
