Sensor API for the BHI160 are also available on our GitHub: https://github.com/BoschSensortec/BHy1_driver_and_MCU_solution. As stated in the Readme, these drivers support for BHA250 and BHI160 (also their respective 'B' variants), therefore the repository took the name "BHy1" to cover all part numbers of our 1st generation of Smart Sensors (Hubs).

Please note that the sample code you linked is for the BMA400 rather than the BMA456. A (soft) reset is typically not necessary, but can be used to restore a known configuration/state to a sensor. Regarding BMA456's interrupt not firing, it is not clear why it is not working based on your sample code. Re-using your configuration for the accelerometer and the no-motion feature, I have written the attached example code. This example successfully runs in COINES (available from our Downloads page, Software tab) and confirms the no-motion interrupt is working by checking the level of the INT1 pin, as well as verifying the interrupt source in the INT_STATUS registers. It prints acceleration data in the console during motion, and a debug message if the no-motion interrupt is triggered.

The sensor refers to the 1g value of the location where the last calibration was performed. For most applications, the slight difference in g values at different locations doesn’t influence the application performance.

As mentioned in the other topic you have linked, the initial obervation reported of IAQ dropping to 0 for unexpected long duration of time could be linked to a glitch in the state file if one was used in the output you have shared. Since an accuracy=1 reflects that only low stimuli have been observed over BSEC's history, it is indeed possible that it remained at this value if the air quality itself in the room was stable for that same duration. This also seems to be confirmed as no significant events were seen in the IAQ output during this period.

Your values seem correct, but also highlights that the order of magnitude of CO2 and VOC concentrations are quite different. In a same way, CO2 sensors are VOC sensors are sensitive to their respective orders of magnitude, therefore VOCs can be detected even if they only represent a portion of the remaing 1% in this example.
