We tested and compared the best smart irrigation controllers that use weather data, soil sensors, and flexible scheduling to cut outdoor water waste. Our top pick is the Rachio 3 for its Flex Daily scheduling and Weather Intelligence, with budget-friendly alternatives from Netro and Wyze.
A typical lawn sprinkler runs whether it just rained or a heatwave is coming. That's a lot of wasted water — and money. Smart irrigation controllers replace the old timer with a system that checks local weather, soil conditions, and plant needs before deciding when to water. The EPA estimates that households using WaterSense-certified controllers save an average of 8,800 gallons of water per year.3
Here are the best smart sprinkler controllers for saving water right now.
The Rachio 3 is the most recommended smart sprinkler controller across expert reviews for good reason.1 Its Flex Daily scheduling adjusts watering based on real-time weather, soil type, and plant zone data. It also includes a feature called Weather Intelligence Plus that skips cycles when rain is forecast and adjusts run times when temperatures spike.1
It works with Alexa, Google Assistant, and Apple HomeKit, and supports up to 16 zones depending on the model. The app is polished and gives you fine-grained control over each zone's schedule.2
The Orbit B-hyve offers many of the same weather-aware features as the Rachio at a lower price. It uses local weather data to automatically adjust schedules and includes a rain delay feature that pauses watering after precipitation.2
It's compatible with Alexa and Google Assistant, supports up to 12 zones, and has a straightforward app. For homeowners who want reliable smart watering without spending top dollar, this is a strong pick.
The Netro Sprite is a compact, affordable controller that still earns EPA WaterSense certification. It uses real-time weather data and supports zone-by-zone customization. The app provides water usage reports so you can track your savings.2
It works with Alexa and Google Assistant and supports up to 8 zones. If you have a smaller yard and want a no-fuss smart controller, the Sprite delivers the essentials.
Wyze brings its signature low price to the smart sprinkler category. The Wyze controller includes weather-based scheduling and rain skip functionality, so it won't water your lawn in a downpour. It supports up to 8 zones and integrates with Alexa and Google Assistant.2
It lacks some of the advanced soil and plant customization of pricier models, but for the price, it's a solid entry point into smart irrigation.

Smart irrigation controllers save water by replacing fixed schedules with decisions based on actual conditions. Key features include:
The EPA's WaterSense certification is the gold standard here. Controllers that earn the label have been independently tested to reduce outdoor water use by at least 30% compared to a standard timer.3
Zone count matters most. Count how many sprinkler valves you have and make sure the controller supports that many zones (plus one or two for future expansion).
Indoor vs. outdoor mounting: Most smart controllers are rated for indoor installation only. If you need an outdoor unit, check the IP rating. The Rachio 3 offers an outdoor-rated enclosure.
Wi-Fi stability is critical — a controller that loses connection can't adjust to weather changes. Place your router close enough that the signal reaches the garage or utility room where the controller lives.
Smart home integration: All of our picks work with Alexa and Google Assistant. If you use Apple HomeKit, the Rachio 3 is the best option.1
