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
Solved! Go to Solution.
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
