I’ve had my wyze floodlight for around a year and it seems the PIR is no longer detecting motion and turning the lights on. Cam is still working fine, and I can manually toggle the floodlight off and on. But when I go in the app to adjust the sensitivity of the PIR sensor, and then tap the button to test it, walk around under the unit, nothing happens. Likewise, when I drive up in the car, the lights don’t turn on like they used to. Is there any solution or do I need to replace the thing?
