    BME680 sIAQ and CO2 sudden permanent increase

    BME680 sIAQ and CO2 sudden permanent increase

    I've been running an BME680 in combination with an esp8266 and esphome for a few months, which had been giving me very plausible estimated CO2 and (static) IAQ levels. However, since a few days both appear way off, even next to an open window CO2 levels would be 1400 ppm and IAQ well over 200, which used to be 500 ppm and ~35 IAQ.

    Any thoughs what might have caused this sensor to be thrown off, and suggestions how to mitigate this ?

    How far back go the reference values for calculating the sIAQ (is that the 28days in the config filename ?)?
