No offense, but your irrigation system controller might not be “the sharpest tool in the shed”.
Does your yard get watered the same days of the week and with the same duration, no matter the change of season?
Does it keep chugging away through a rain shower, or on a day when the howling wind blows most of the water onto your driveway?
This little component may not be all that smart.
However, smart irrigation system controllers have changed the way we water.
