Installing a smart sprinkler system for your yard is a simple way to cross one more thing off your weekly to-do list. The best smart sprinkler controllers have enough zones for your yard, access to local weather forecasts, and can be controlled with an app as well as smart home assistants.

Most smart sprinkler systems have multiple yard zones, which can be independently programmed to give your plants the right amount of water. According to Nicole Chernyakhovsky, owner of Larkspur Landscaping, this is important because “grass, trees, and shrubs’ water requirements differ from flower and vegetable gardens. Soil type, yard slope, sun exposure, and nozzle-head types also impact your water needs.”

To accommodate all these scenarios and help your plants thrive, you’ll need one zone for each area of your yard. Four-zone sprinkler controllers are usually fine for smaller yards with just grass and flower beds, while larger yards with a wider variety of plants could need as many as 16 zones.

To give your plants the perfect amount of water, no matter the weather, you’ll also want a smart sprinkler system that has access to local forecasts. Chernyakhovsky advises, “You can set your sprinklers to suspend watering during high winds, rains, low temperatures, or even based on the previous day's rainfall.” Some sprinkler systems use the closest weather stations to get a forecast, while others connect to sources like the National Oceanic and Atmospheric Administration (NOAA).

While smart sprinkler systems have many features, the best models are compatible with apps that make them easy to use, even when you’re not at home. Many systems have their own free apps that you can use to set schedules, control the sprinklers, record water usage data, and more. For even easier control, you may want to integrate your sprinkler system with your smart home assistant, so check your system’s compatibility before buying.

Check out this list of the best smart sprinkler systems to simplify and improve your home yard care.

One fan raved: “This is worth every penny! Ditch that old sprinkler system asap. You control this directly from your phone. It makes everything organized and convenient.

One fan raved: “We purchased one of these for the front yard as a trial [...] We were happy enough with our trial that we ordered a second controller for the backyard. I love that it puts itself on automatic delay based on the weather. I get a confirmation notification to my phone and apple watch that watering has completed. I've checked our cameras to verify that the yard did get watered, and all is good! Installation and setup was very easy.”

This sprinkler uses realtime forecasts to adjust for rain, freezes, and more, and it can also monitor local water restrictions to keep you updated on the latest guidance.

One fan raved: “I've been thinking about putting a camera in my garage. One day a friend mentioned Yardian to me, and I was pleasantly surprised to know that with Yardian, I can upgrade my existing sprinkler controller to a WiFi/smart version with a camera in one single device! After some research on the web, I decided to purchase Yardian [...] I like Yardian a lot, and I highly recommend it. It's really a "smart" device that needs no effort to set up and maintain.”

You can control this sprinkler with the iOS or Android app, or through voice control with a variety of smart home assistants. To get the most accurate forecasts, this system uses multiple weather sources, including NOAA, and downloads the forecasts every six hours so it’s always up to date. If you want to save water, this sprinkler is also a good option because it is EPA WaterSense certified.

One fan raved: “If you have sprinklers, you are doing yourself and the environment a disservice by not having a Rain Machine! It waters the correct amount, every time, based on the (very) local weather. This is my second Rain Machine (I added more zones so needed the “16”) and last year (2020) in a NY summer, I saved over 80,000 gallons of water, instead of “just running” my sprinklers everyday (I have 2 acres of property) Worth every penny and I hooked it up by myself ( and I’m not all that handy)”
