Hi there. I have something that may be related. I've built numerous prototypes with BME280s as well as production devices. In this thread the "working device" has a data dump showing a calculated pressure of Pressure: 71354.62 Pa. I would assume that was taken at nominally sea level instead, but that value seems much too low. I'm at sea level approximately at the moment and my units are also showing very similar values. I've always assumed I have a bug someplace in the compensation code, though it is a cut-and-paste from a Bosch code example. The temperature and humidity values seem to be correct, and my calibration parameters are very similar (and sometimes exactly the same as) those in the thread above for a "working unit". So let's start with a simple question: Is that pressure reading in the right range of expected results ?
