I found these on Amazon, and I ordered them right away. Based on what I know these will be turning on my front porch and outside lights when the sunsets and then back off when the sunrises. This will happen automatically, because I will tell the switch what my longitude and latitude are on the earth. Pretty amazing stuff. I was busy this weekend completing the plumbing, and conduit work, while my contractor/builder completely finished out the guest house, or second container. I will post that in the next couple of days as there is a lot of work to catch up on.
