I used plot juggler instead to get the device ids of the imu by doing the following action
import data from two PX4 log files and checking the imu_device id graph. i hope this is correct. It looks the ids matched for both PX4 v1.12.3 and PX4 v1.13.3
Also attached a PX4 v1.12.3 log file taken back in Jan / Feb 2023 at the same spot

Hope this is acceptable …
