Hello wtc-peg, Currently, BME680/BME688 only supported IAQ index output. ... View more

There is no further AppNote/documentation than the BME680 datasheet and documents in the BSEC release package. The static-IAQ output still tracks air quality history so that 25IAQ corresponds to typ. good air observed, but uses a fixed sensitivity. The range of the sIAQ output has been unlocked above 500IAQ, and you should experience a more linear response/behavior of the output. ... View more

So not in any case it can be perfect 😉 Michael ... View more
