Table of Contents: How to Set up a WiFi Irrigation Controller
Smart WiFi irrigation controllers are one of the easiest ways to save water, reduce utility bills, and make your life a whole lot easier. Instead of adjusting your sprinkler schedule manually or guessing how much your lawn needs, a smart controller can do it all—automatically.
Most models can adjust based on local weather, control zones independently, and be programmed from your smartphone. Here’s how to get set up and take the guesswork out of watering.
Step 1: Choose the Right WiFi Irrigation Controller
Before you start installation, choose a controller that works with your sprinkler system and meets your needs. Popular options include:
Make sure to check how many zones you need, whether it’s compatible with your valve wiring, and if it supports features such as rain sensors or flow monitoring. Also verify that it works with your home WiFi and smartphone operating system.
Step 2: Shut Off Power and Disconnect the Old Controller
Safety first. If you’re replacing an old controller, turn off the power at the breaker. Then, take a photo of your existing wire setup for reference. Unscrew the wires and remove the old unit from the wall.
Mount your new smart controller in the same spot if possible. Most units come with mounting hardware and an installation guide.
Step 3: Connect the Wiring
Match each zone wire to the corresponding terminal in the new controller, just like in your old setup. Usually, wires are color-coded. Don’t forget the common wire (C terminal)—this is essential for operation. If your controller supports sensors, you can connect those, too.
Once wiring is complete, plug the controller into a GFCI-protected outlet and restore power.
Step 4: Connect to WiFi and Set Up the App
Download the manufacturer’s app on your smartphone or tablet. Most smart controllers will walk you through setup with a step-by-step wizard. You’ll typically:
- Connect to the controller’s local WiFi signal
- Select your home WiFi network
- Sync the controller to your account
- Assign zones and optionally name them (e.g., “Front Lawn,” “Flower Bed”)
- Set up watering schedules or choose smart auto-adjust settings
Many apps allow for weather-based automation so that your sprinklers won’t run when it’s raining. You can also control zones remotely, which is handy for quick tests or last-minute changes.
Step 5: Test and Adjust
Run a quick test on each zone to make sure everything is functioning. Walk around and observe water pressure and coverage. Adjust sprinkler heads if needed.
Over time, use the app’s reporting tools to fine-tune water usage and schedules.

Once you’ve got your WiFi controlled sprinkler setup installed, you’ll wonder how you ever lived without it.
