IAQ value not updating (BME688, BSEC2.0)

[MightyNate]

Hello,

I'm trying to measure the IAQ with a BME688 sensor and the new BSEC2.0 library on an RaspberryPi.

I had everything working with the BME680 and the BSEC1.4.

All values despite the IAQ are calculated and updatet correctly but the IAQ status is 0 even after letting it run for over 20 minutes.

What could be reasons for the IAQ to not update?

Thanks for any advice

I just let it run for over 1,5 hours and still no change.

Hello MightyNate,

Which power mode you configured?

[MightyNate]

I'm running the sensor in Low Power mode.

I just noticed, that the heat compensated temperature is constantly at around -4 degC which is very unrealistic.

The raw temeperature is at around 29 degC which matches the weather prediction for my location.

Might this be a hint  for what is going wrong?

Besides I'm not using a statefile for the moment and I checked the timestamps, they seem plausible.

Still the iaq accuracy is always at 0 even after hours of running in Low Power Forced Mode
