detection of wireless charging

Is it possible that the detection of (wireless?) charging is slow/unreliable when motion detection setting in preferences is turned on?

Background: I have a home profile that becomes active when either wifi connection OR location (geofence) indicate that I am at home. Since I do not want the home profile to be active when my car profile is active I also added the condition “not car-profile active”. The car profile becomes active as soon as wireless charging is detected and stays active as long as the phone is in contact with the wireless charger. – Now, when I leave home, detection of wifi disconnection and crossing the geofence are slow, according to the online help. However, since I have added “motion detection on” in the home enter task, the detection of the wireless charger seems slow / unreliable to me as well. I have the impression that the car profile does not start unless the home profile becomes inactive (=wifi disconnected AND not at home location).

Please let me know if the charging state detection is also affected by the motion detection preference and if this behavior is intended.
