if your goal is: lights always on when garage is occupied the leviton occupancy sensor is the way to go; the trick is: don't put in place of existing switch if that won't help it notice if there is a car or person in there. It seems to be heat sensing. if there is something 'not room temperature' in there that is 'not moving' the light will stay on until that condition is no longer.

I use them in my bathroom, kitchen and hallway and there is no going back.

recently i used to add automatic lighting to four closets. i put a new 'retrofit box' right next to the light outlet in the ceiling and put some BX back and forth to the new box where i installed the switch to look down and out the closet door. This same concept would work for a garage; maybe fish wire up the wall to have an overhead view looking down and over a 'near' car that may block it's view.

The switch has about a 160° view angle and maybe 30° down. I have one on a side of a hallway and it works both ways down the hall.
