@Jimi: this is depending on the environment the bme280 is working. The data sheet mentions that the operation range is only for non-condensing environments. If you run your BME280 indoors, you're most likely fine. I ran some of them outdoors, in very humid conditions, especially below freezing point, the BME280 is just not the right sensor to use.
