Programmable Light Switch Timer

Sunset and sunrise light programming

Between the front and back doors, a patio, a balcony, and a garage, my house has a bunch of entrance lights that I like to have on in the evenings (switching to LED made me feel less guilty about it). After some experimentation with IoT options, I settled on this simple time-based on/off switch. The device is completely autonomous, doesn’t talk and doesn’t listen, needs no network, software updates, or even batteries. It simply keeps track of the sunset and sunrise based on the latitude and longitude that you choose during setup and it even self-adjusts for Daylight Savings if you so wish. It’s been a few years and more than few power outages, but the switches continue to keep time and operate flawlessly.
