The entire system works on a low-voltage timer, similar to a Malibu light systems. Here is an image of the controller. It's the black box, which controls the low-voltage lighting for the fence lamps as well as the lights in the fountain in this garden. The gray box is the irrigation controller for the garden. The small black dot on the conduit pipe between the two controllers is a network port that allows us to control our irrigation via a computer here inside the house or by a weather station that I'm saving up for at this time.
