For example, I have my backyard perimeter lights on a smart switch and I have them go off at 11:00 once in awhile we're out in the backyard past 11 and I can have them turned back on without getting up.
In my opinion the only advantage is if you don't keep them on all the way until dawn and you may have need to change the times on occasion. Is there an advantage of having the smart switch versus a light sensing dusk to dawn?
