I want my lights to go on every day at sunset and then off at 10 pm. We have light timers for that. Do you need to turn your pool pump on and off 4 times a day? We can do it. It would great to hit a button to turn on your bath exhaust fan when you get in the shower and turn off automatically 20 minutes later. They make many kinds of light switch timers today. Astronomical timers know the area you live in geographically and can turn things on and off based on sunrise/sunset without you ever having to change the timer for the change in seasons. If you haven’t looked at timers lately, maybe it’s time!
