Problem with BME680 IAQ accuracy

[Ochrin]

Hello,

I am using the latest version of BSEC (1.4.7.3) as of today. This version solved the issue of IAQ staying to zero but I still have an issue with IAQ accuracy.

See these 2 links:

These are the IAQ and IAQ accuracy measurements for 2 different devices sitting next to each other.

We can see that since several days, the IAQ accuracy is 1 and does not change anymore.

I don't get any error messages from BSEC library. So I don't see what I could do wrong.

Does anyone may have an idea at what I should look/investigate?

For info, I am running the bsec library on esp8266.

Thanks for your help.

Your links seem to require a login to view the data. Would it be possible to also include the input signals (temperature/pressure/humidity/gas resistance) to better understand what the sensor is measuring?

Thanks for the answer.

Here are the images of the 2 links I wanted to send.

For now, I don't store the gas resistance, only temp, humidity, pressure, iaq and iaq accuracy. So I will update my firmware to store all of them and once I have results for one week, I will come back to you.
