Hi Sepro,
Thanks for your inquiry.
The completion of IAQ backend calibration takes time, and the calibration time depends on the configuration you are using. For example, generic_33v_3s_28d, the backend calibration time will take 28 days.
In addition, when you check the IAQ and CO2 output, you can also check the calibration accuracy value to see whether the calibration is currently completed or in progress.
