What to Consider When Choosing the Best Smart Sprinkler Controller
In the same way that having an automated lawn mower will save you from time spent maintaining your lawn, a smart controller will make effective watering decisions, so you can spend more time doing the things you enjoy.
If you have an underground sprinkler system, it’s likely set up in zones to ensure that there’s sufficient water pressure to lift the sprinkler heads in a specific area of your lawn, one zone at a time. The larger the yard, the more zones. A smart controller will accommodate a specific number of zones, anywhere from about 2 to 16. You can usually find a zone setup diagram on the inside of your existing watering system control box.
Smart sprinkler controllers come with apps you download to your smartphone or another digital device. Some sync with smart home systems such as Amazon’s Alexa, which lets the user turn the water on or off via voice control. You can configure most from either a smart device or directly on the unit itself.
For a smart sprinkler controller to work, your home must have WiFi. The controller syncs with your home’s router. Different controllers are also compatible with various smart home systems, such as Amazon’s Alexa, Google Assistant, Wink, and Samsung SmartThings. So if you have an existing smart home system, consider a compatible controller.
With many of today’s smart controllers, you won’t have to worry about changing the watering schedule during times of heavy rain or drought. Smart sprinkler controllers automatically download weather data in your area by using your zip code and adjusting the watering schedule depending on the weather.
For example, suppose you configure your controller to water all parts of the lawn with 1 inch of water per week, and it rains ½ an inch. In that case, the controller will automatically adjust the watering schedule to provide an additional ½ an inch rather than a whole inch that week.
Many smart controllers come with the ability to notify the user in case a problem arises, such as a water shutoff; a faulty valve that’s keeping the system from turning on or off; or excessive water flow, which could indicate a broken sprinkler head. Some apps can be configured to send text messages or audio alerts to your smartphone, while others emit an audible signal to alert anyone in the yard.
EPA WaterSense Certification
To conserve water, look for a smart sprinkler controller that comes with the WaterSense label, which means the controller meets EPA standards for conserving a maximum amount of water without underwatering. In addition to utilizing information about the weather and rainfall in your area, the controller will also monitor your community’s watering ordinances during a drought, so you won’t violate any watering rules.
Many smart sprinkler controller units are installed on the exterior of your home. Others have the option of being installed on an interior wall, such as a garage or foyer wall, so you can check the controller without having to go outdoors. The controller often pairs with an inground sprinkler system, but different models will also pair with a drip-irrigation system or even a garden hose.
Mounting is relatively simple, as the new smart controller works in conjunction with the existing controller. You’ll download the supporting app first, which will walk you through the rest of the setup process. Access to an electrical outlet to power the controller will be required, or the unit will need to be directly wired into your home’s electrical system. The latter requires an electrician to run the line.
Our Top Picks
To qualify as a top pick, a smart sprinkler controller must be capable of handling the existing watering zones in your yard. And it should have an app that’s simple to understand and will allow you to configure the controller and then relax and let the controller do all the rest. The following seven smart sprinkler controllers will work in various watering situations, and one will likely match your lawn’s watering requirements.
The Weather Intelligence Plus feature on the Rachio 3 Smart Sprinkler Controller comes with local weather integration to make watering your yard more efficient. An intuitive downloadable app makes setup a snap, and it will control up to eight watering zones.
From your smart device, you’ll be able to see your estimated outdoor water usage and configure watering schedules. You can also fine-tune the schedules by entering the type of grass being grown, soil type, and even how much sun exposure a specific zone receives.

You don’t have to spend a lot of money to enjoy the convenience of a smart sprinkler controller. The Orbit 21004 B-hyve Smart Sprinkler is designed for use with a traditional hose. While it controls only a single hose, you can attach a multiple-faucet sillcock to your exterior faucet and add an Orbit controller to each head for more watering options.
This affordable controller is also WeatherSense certified, so it will adjust watering to suit your area’s current weather conditions as well as gather information about local watering ordinances. You can also configure the app to consider soil type, grass type, and site conditions, such as whether your yard slopes. Monitor your water usage and receive alerts on a smart device.
If watering with a standard garden hose, check out the multifunction LinkTap G2 Smart Sprinkler Controller that adjusts watering time based on current weather data. It will alert you if a problem occurs, such as the unit falling, a water shutoff, or a broken valve allowing water to flood out. You can also configure the app to send an email alert to a family member or neighbor when out of town.
The intuitive app makes setup easy, and you’ll be able to see 90 days of water usage. You can also enter your per-gallon rate from your water bills to see how much money is being saved while watering.
For an easy-to-use controller with a responsive touchscreen display, check out the RainMachine Touch HD-16 Smart Wi-Fi Irrigation Controller that comes with a large, color touchscreen display that allows you to view water usage and set a schedule right from the unit, as well as from your smart device.

The 16-zone RainMachine is WeatherSense certified, so you can rest assured you’re conserving as much water as possible while your lawn still gets enough to stay lush and green. The controller is compatible with Alexa and can gather weather data from your choice of national weather stations or even your own private weather station.
If you want to mount a controller unit indoors, consider the Orbit Indoor/Outdoor Smart Sprinkler Controller since it doesn’t need to be mounted right by the watering system. Instead, you can mount it inside a garage or inside a back or side door where you can view the screen and program the unit without going outdoors.
The Orbit offers all the same perks as other smart controllers, including the ability to regulate watering cycles based on current weather data in your area. It is also WeatherSense certified for conserving as much water as possible. Program the controller remotely via the smartphone app or from the controller unit and receive alerts both on the unit and on your smart device.
