Thank you for the feedback, as the camera motion sensor detects the motion compared to the pixel changes, some unwanted alerts can only be reduced as much as possible by adjusted some settings.  Please check some tips here in FAQ here to reduce unwanted detection activities

How to reduce motion detections from rain,snow or insects

• Set Camera Sensitivity to Low or Lower levels

• Turn on Person Detection and deactivate the Motion Detection settings temporarily when there is rain

You may also adjust or turn off the notification settings temporarily when there is rain.
