Irrigation Controllers

Upgrade your system with controllers that do more than turn sprinklers on and off. Our Irrigation Controllers collection brings you advanced, smart-ready devices built for efficiency, precision and flexibility.

Whether you’re managing a home lawn, a large professional install or a combined drip + sprinkler system, the right controller makes the difference. Smart controllers use real-time weather data, soil or zone-specific scheduling and remote access to optimize watering and reduce waste.

Certified models, like those labelled under the U.S. Environmental Protection Agency’s WaterSense program, can save thousands of gallons per year simply by avoiding over-watering.

In this collection you’ll find:

  • WiFi-enabled and app-controlled controllers that let you manage your system from anywhere—ideal for busy homeowners, property managers or pros.

  • Multi-zone controllers capable of handling everything from 4 zones to 48+ zones, perfect for expansions, drip landscapes or commercial installs.

  • Weather-based controllers that adjust watering based on temperature, rainfall, wind and ET (evapotranspiration) data, helping protect plants and conserve water. 

  • Durable indoor/outdoor models with freeze/rain sensors, manual overrides and compatibility with pumps, master valves and sensors—matching pro-level system needs.

  • Controllers compatible with both sprinkler and drip systems—so your entire irrigation layout can be managed under one smart roof.

Why shop with Big Frog Supply? Because we understand irrigation, plumbing and lighting—and know controllers aren’t plug-and-pray. We give you expert-curated models, clear specs and real-world help so you pick the right one for your zone count, system type and budget.

Pro tip: Before you buy—count your zones (sprinkler zones + drip zones), check if you’ll need pump start or master valve wiring, decide if remote control is important, and ask if your local water-utility offers rebates for smart controllers.

Browse the collection, pick the controller that fits your system size and tech expectations, install with confidence—and manage your watering from your phone.
