I have two outside lights on my garage that are wired to a switch in my kitchen.
What I want to do is have them turn on for X hours at dusk and then switch off. I then want them to turn on via motion detection whenever there is motion and it is dark outside.
I have not seen anything on the market but I know that I could wire you a simple control panel panel with a timing relay on a light sensor and a bypass circuit controlled by the motion detector.
^^ That is a pretty cool product, unfortunately the reviews are pretty bad. I think that I may pick one up just to try it out since my switch and light are pretty close.
