I just installed a Lutron Occupancy Sensing Switch. At first, the light was off. Don't know what I did but it came on. It's been over five minutes (the default setting) and the light did not go off. I tried to change the timeout settings, held the button as shown in the picture but no sensor light flashed. Same thing with changing the sensor mode, held the button on the side but no sensor light flashes. I even tried to reset all settings to default by holding both buttons, the sensor light didn't flash. The switch's ground wire is connected to the ground wire in the switch box. Any ideas what is going on?
