I want a controller that will turn on my lawn sprinkler valve at 5:00 PM every day and off at 5:30 PM. I know I could build one from a Tiny85 and 5 or 6 lines of C code, but I'm too mentally lazy and don't have time for that sort of menial labor.
I want something that I can take out of the box, connect to my computer, type "turn on sprinkler valve at 5 PM and off at 5:30 PM every day", plug power into one end, sprinkler valve into the other and be done with it. Any recommendations?
