What you’ve turned off is motion notifications. That’s different than event notifications. With motion notifications, you’ll receive a notification on your phone the moment there’s motion. That’s independent of whether or not your motion sensor triggers recordings on a camera.
If you’ve set your motion sensor to trigger recording an event on a camera, that CAMERA will still send you an event notification when it records an event, if you have notifications for camera events enabled. If so, that will probably arrive on your phone about 15 seconds after the motion event.
All of that seems like expected behavior to me.
Is your motion sensor directly next to your camera, pointed in the same direction, etc? Is it outdoors or indoors? If it’s outdoors, you’re always going to get a ton of false positives. The environment outdoors is too unpredictable. Wind carries heat with it, a bird can fly in front of the sensor, etc.
Are you getting NOTIFICATIONS for these? Or they’re simply appearing in the event history, without your phone actively notifying you about it?
Obviously they’d show in the event history. Why are you triggering a camera with a motion sensor if you don’t want to be able to review the event in your event history? I’m not sure I understand your problem.
