False motion detection on smart lighting motion sensor

Did anyone notice that the new firmware of the smart lighting motion sensor often gives false motion detections these days? I have two motion sensors. The one I am using which I believed just upgraded the firmware version to 1.8.8-33 has continuously report false motion detection even I set the sensitivity to 1. Now I replace it with my old one with the firmware 1.8.3-29. Everything back to normal even I set the sensitivity to 4 or 5, it won’t do the false detection. Is there any way that I can roll back my firmware?

I haven’t noticed any false motion alerts with my motion sensors running the same version of the firmware as of yet, but I’ll keep monitoring it.
