Test the rain sensor
The law requires one that works.
Because the rain sensor the law requires failed years ago and nobody tested it.
Florida requires a functioning rain sensor or soil moisture device on every automatic irrigation system, and the requirement is widely met on paper and rarely in practice. The devices fail quietly after a few years, the system keeps running its schedule, and the only symptom is a water bill and sprinklers working through a thunderstorm.
The second universal fault is zoning and run times. Systems are routinely installed with planting beds and turf on one zone, which guarantees that one of them is wrong, and run times are set by whoever happened to be standing at the controller. Measuring what each zone actually applies, with catch cups, turns guesswork into a number.
What irrigation cannot do is save a lawn that is failing for another reason. Fungus, chinch bugs, compaction and mowing height all kill turf under a perfectly tuned system, and a contractor who blames the sprinklers for all of it is selling repairs rather than diagnosing.

Catch cups beat experience.
Schedules are set to what applies now.
Free, with every zone run and watched, and no obligation.
