I installed an occupancy sensor in my laundry room. The light stays on continuously. After verifying that I had all wires correctly spliced and insuring that the ground from the sensor was run to the metal outlet box, I called the technical support (for the product). The technician verified my wiring connections. Then he told me that the reason the sensor would not shut off is because my house ground is not strong enough. I've been reading about house grounding problems, but have not found a good solution. I think I need to improve the ground connection which is located outside near the fuse box, but I do not know how to do that.
