We've tested each one in real homes and real yards with testers across the country, rounding up the five best smart sprinkler controllers.

The Rachio 3 Smart Sprinkler Controller is our No. 1 pick for smart sprinkler controllers, because it's an all-around easy to use device. From installation to managing your system daily, the Rachio 3 Smart Sprinkler Controller is the best of the best.

It comes in 8- and 16-zone options and has features like Weather Intelligence, which skips a watering cycle if rain is in the forecast, and Smart Cycle, which help break up watering sessions into shorter, more effective spurts.

You can also manage it via the Rachio app for iOS and Android.

If you're looking for a smart sprinkler controller full of value and low on price, check out the Netro sprite.

The fully automatic Wi-Fi-enabled smart sprinkler controller uses local weather data and information about your lawn to help craft the perfect yard watering schedule.

It works with Alexa and Google Assistant, and you can also manage the Netro Sprite in the Netro app for iOS and Android.

The Wyze Sprinkler Controller is full of customizable and intuitive features that water your yard efficiently, helping to keep the grass green while saving you money.

It supports up to eight zones and you can manage the controller in the Wyze app, where you can set certain weather conditions to help the controller skip a watering cycle due to temperature, rain, wind and saturation levels.

A Wyze Sprinkler Plus subscription is required to access features like smart schedules and weather skips.

The Orbit B-hyve Wi-Fi Sprinkler Timer is available with support for six or 12 zones. It is can be installed outdoors and comes with a keyed lock to keep the LCD control panel covered.

The controller uses data about the amount of sunlight your yard gets, zip code, the type of plants in your yard and soil composition to determine the best watering plan for your lawn. 

The Scotts Miracle-Gro smart watering controller is simple to install, but it is a bit limited in functionality.

It offers features like fixed or interval water schedules and a "hibernation" mode for when the sprinkler system isn't in use for long periods of time, like winter.

If you don't need advanced features and only want access to the basics, like turning the system on and off from your smart phone, then the Scotts Miracle-Gro Smart Watering Controller can help get the job done.
