Before giving up try a quick test to find the trigger path. Tape a thin strip of tissue paper over the door gap inside the closet and close the door. If you find it moved in the morning the sensor probably saw that same draft. Then mask the lens on that side with a tiny wedge of opaque tape and add a narrow door sweep so the pressure change does not push air past the crack. If the tissue stays still look for a heat source change instead. Water heater on a timer, attic hatch above, even a charger in the closet can create a gentle plume. Shift the light so the sensor stares at a blank wall and give it a short auto off setting so any rare false trip is brief. That combination usually tames them.
