Smart, Weather-Based Sprinkler Controllers Explained
One of the biggest causes of wasted water is a 'set it and forget it' sprinkler timer running the same schedule year-round. Smart, weather-based controllers fix that automatically — and they're one of the best upgrades a Southern California homeowner can make.
How smart controllers work
A smart controller adjusts your watering automatically based on real conditions — local weather data, season, temperature, and your specific plants and soil. Instead of running a fixed schedule, it waters more in a heat wave and less (or not at all) when it's cool or raining. Many connect to Wi-Fi so you can control them from your phone.
Why they're perfect for our climate
The Inland Empire's swings between mild winters and brutal summers make fixed schedules especially wasteful. A weather-based controller adapts to those swings, skips watering after rain, and keeps you compliant with local watering restrictions — all without you lifting a finger.
The benefits add up
- Lower water bills from eliminating overwatering.
- Healthier plants watered to actual need, not a guess.
- Rebates: many water districts offer rebates on qualifying smart controllers.
- Convenience: adjust or shut off watering from your phone, anywhere.
Getting the most from one
A smart controller works best when programmed correctly for each zone's plants, soil, and sun. Pairing it with drip irrigation and a rain sensor maximizes savings. Our irrigation team can install and dial one in for your yard.
