Why did my sprinkler controller skip watering after rain?
Short answer: A connected rain sensor can interrupt scheduled irrigation after sufficient rainfall — the controller skipped on purpose, because the sensor told it the lawn had already had enough water.
A rain sensor measures rainfall and, once it reaches its set threshold, tells the controller to hold off watering until the sensor dries out. That is exactly what it is supposed to do, and in Texas it is not optional on new automatic systems — TCEQ rules (30 TAC §344.62(j)) require new automatically controlled systems to include a rain or moisture sensor, or other technology that interrupts operation during rainfall, and the same sensor is required when an existing controller is replaced.
If the system skipped after only a light sprinkle, the sensor may be set too sensitively, stuck, or shaded in a spot that stays wet. We check the sensor setting, its location, and whether it has dried out and reset — a sensor that never resets is a sensor that needs replacing, not a controller problem.
What we check in New Caney
This is a common call in New Caney, and it is the kind of problem we test in the yard instead of guessing at from the driveway. We run the system, watch how the water is actually moving, and check the parts that cause this — before anything gets replaced. That is the same approach in the full Smart Controllers service page.

Frequently asked questions
How much rain should trigger a skip?
A common setting is around a quarter-inch of rain. If your sensor trips on a heavy dew or a five-minute shower, the setting or the sensor itself is worth checking.
Is a rain sensor required in Texas?
Yes, on new automatically controlled systems — and when an existing controller is replaced — under 30 TAC §344.62(j). It is also simply good practice on any system, because it stops the sprinklers from watering in the rain.
