I recently installed a censored light on our porch, with the 'dusk to dawn' feature. Everything works great for that light. My question is about the corresponding driveway light post thats also on the same light switch.

When I flip the interior light switch that powers the porch light, it also turns the driveway light post on and off. I thought that when I installed the porch light with the sensor, that when it turned on and off (because of the dusk to dawn feature) the driveway post lamp would as well, but it stays on all the time. Is there anyway to activate this? Or does the driveway light need its own sensor?
