Key features:

  • Scientifically precise watering
  • Intelligent weather skip technology
  • Remote app control
  • Flexible scheduling options
  • Fastest and most stable connection

ImoLaza’s Smart Sprinkler Controller combines technological innovation with environmental stewardship in a way that’s revolutionizing lawn care. This 6.3 x 6.3 x 1.18 inches, 2.57-pound device strikes the perfect balance between efficient water usage and optimal plant health. Our hands-on testing revealed the effectiveness of this 8-zone WiFi irrigation controller in a real-world context. Built on a powerful 2.4GHz WiFi System-on-Chip (SoC), the unit boasts exceptional wall penetration, ensuring a stable and uninterrupted connection.

The controller’s New Grass Schedule feature, allowing up to 24 start times, proved particularly useful for high-frequency watering needs. The controller uses an advanced evapotranspiration algorithm to calculate the optimal watering frequency and duration for different zones, preventing both underwatering and overwatering.

In our test, this meant that regardless of weather changes, the plants received exactly the right amount of water, promoting lush growth and vibrancy. Overall, ImoLaza’s Smart Sprinkler Controller sets a new benchmark in smart irrigation, demonstrating a perfect fusion of advanced technology and sustainable practices.

Since we have been using the ImoLaza for about a month now, we’ve barely bothered with it. We checked the irrigation records for the past month and found that it surprisingly skipped every rainfall with total accuracy.


In contrast, Hunter, Rainbird, and Orbit irrigation controllers have a much-more complicated App, which can be a bit difficult to understand. ImoLaza, on the other hand, has a clean and simple interface that’s very smooth to use and quick to get started without any difficulty.

ImoLaza is undoubtedly the best choice, both in terms of connection speed and stability, as well as in terms of the water-saving technology used and the accuracy of weather data.

Rachio 3 Smart Bundle

Key features:

Setting up the device proved to be an effortless task, thanks to its DIY-oriented design. We were able to replace an old controller, wire up, and complete the setup through the Rachio app in about 30 minutes, even without any special tools. The app itself is intuitive and user-friendly for the most part, allowing control of the sprinklers and visibility of upcoming schedules and estimated water usage. We felt that some instances were clunky and difficult to navigate, but those were few and far between.

Additionally, Hyperlocal Weather Intelligence Plus is highly beneficial. This exclusive technology leverages data from over 300,000 weather stations, providing accurate forecasts that adapt your watering schedules and prevent unnecessary water waste. What’s more, it intelligently skips watering during rain, wind, or freeze events. Tailored smart schedules were another game-changer. Rachio customizes schedules according to the specific needs of your lawn, including plant type, soil type, and sun exposure.


In our testing, the accuracy of this feature impressed us, ensuring each plant received exactly what it needed. The Rachio 3 Smart Bundle is a step forward in irrigation technology, merging intelligent automation with easy-to-use interfaces, all packaged in a compact design. We like that it’s compatible with Alexa and Apple HomeKit. The added benefit of remote control is always nice to see. And the fact that it measures 9.1 x 5.5 x 1.6 inches and weighs a mere 2.5 pounds makes it a good fit for any garden shed or garage.

What we liked:

  • Easy to set up and use
  • Accurate weather adaptation
  • Effective water conservation

This unit, with dimensions of 4 x 9 x 11 inches, combines functionality and sophistication in a compact, charcoal gray design. Its easy programming, accessed via the free B-hyve App, allows for the creation of watering schedules and duration settings and enables alerts, all from your smartphone. It’s hard to ignore the convenience of the long-range Bluetooth connectivity, which ensures swift device pairing.


Perhaps the most impressive feature is its WeatherSense technology. With it, the unit adjusts water delivery based on real-time weather data, taking into account factors such as rain, wind, and freeze delays. It increases watering during dryer periods, saving both your plants and your time. It’s also gratifying to see Orbit’s commitment to conservation, as the B-hyve XR is EPA WaterSense-certified.


The controller further offers ultimate control, providing status updates via a multicolor LED light ring and three full-color digital displays. A built-in manual watering override button ensures you can control watering without relying on the app. However, during testing, we did notice some connectivity issues when attempting to connect to WiFi.

With a hefty weight of 6.23 pounds and compact dimensions of 4 x 10 x 9 inches, the device is robust and perfect for outdoor use. Easy installation stands out as one of the defining features of this device. Users can quickly set up the controller, utilizing the wiring compartment and terminal strips.


The wiring process is effortless due to the spacious and user-friendly design, ensuring an organized setup inside the box. The controller’s operation is impressively smooth, as well. Utilizing the touchscreen, users can manage all features and also access the full functionality via an app. The interface offers complete control over zones, allowing for a pre-defined schedule based on run times per zone and configured start times.

The device’s smart software, Hydrawise web-based software, maximizes efficiency by adjusting watering schedules according to the local weather data. By monitoring past, present, and forecasted temperatures, as well as wind speed, humidity, and rainfall, the Hunter’s little box adapts to ensure optimal watering. One minor concern was the delay in schedule updates on the free plan, which occur only once a day.


However, with the paid plan, updates are pushed hourly. The system also uses a polling approach when manually controlling a zone from your phone or PC, leading to slight delays. Despite these minor issues, the Hunter PRO-HC PHC-1200’s predictive watering adjustments and smart device compatibility make it a top choice for intelligent irrigation control.

What we liked:

  • Compatible with Amazon Alexa, Google Assistant
  • Water usage reduction up to 30%

Its primary advantage is that it allows the user to fully control an irrigation system using the Rain Bird mobile app. From adjusting watering schedules to monitoring system performance, it’s the epitome of smart gardening. The only thing really lacking is the inclusion of a touchscreen display. While the images might make you think it has one, that’s not the case. Instead, built-in buttons serve as the primary point of control from the unit.


Thankfully, controlling is much more accessible and friendly via the aforementioned app. It’s not the most advanced software (it appears to be built around Android 6.0 and iOS 8), but it really doesn’t need to be from what we experienced. For starters, the ARC8 is adaptable to a wide variety of smart home ecosystems. Equipped to control up to 8 zones, it offers three individual programs per zone and up to 4 start times per zone – a truly flexible system for diverse gardening needs.


The device’s clever features extend to efficient water usage, too. It can reduce water consumption by up to 30% by adjusting or skipping daily watering schedules based on local weather forecasts and historical data. This feature, combined with its notifications about malfunctions, WiFi disconnections, incorrect time/date, or potential freezing, empowers gardeners to care for their plants in a resource-conscious way. Rain Bird’s ARC8 is impressively sized at 7.92 x 3.51 x 7.86 inches and weighs 3.66 pounds. Despite its weight, it’s a good fit for both indoor and outdoor use, and its sleek gray and green design blends seamlessly into any setting.

10 thoughts on “5 Best Smart WiFi Irrigation Sprinkler Controllers [2023 Updated]”

  1. The second edition of the Rachio Smart Sprinkler Controller has made my life a whole lot easier. Out yard sees a lot of sunlight so watering it at the perfect time is ideal if we want to keep it green all year around. Thanks for recommending these, I agree – I think Rachio is the best.

  2. Do any (or all) of these devices enable me to limit the watering to specific day(s) of the week, in order to follow local HOA requirements?

  3. I have a standalone wireless network that is not connected to the Internet

    I am looking for a web based wireless sprinkler controller that can function without connecting to the Internet.

    Are you aware of models that will operate without Internet access?

  4. Thanks for your reccomendations! Last week I came to your site and read about the Rachio and ordered it. I just installed it yesterday and the thing is amazing! Works exactly as I need and we LOVE the smartphone integration.

  5. is it possible to control 9 zones irrigation valves with a 8 zone controller. I am thinking to combine wires for 2 zones which requires lesser water pressure ? Are there any other alternatives

    • I would caution against wiring 2valves on one zone. Most controllers cannot supply the increased current requirement of the two valve solenoids and you risk damaging the electronics.
      Check the installation instructions of your unit.
      Would be better to connect the piping of the two low flow zones rather than wire two valves on one zone.

  6. I have a b-hyve system. Loved it at first. But, the app on my phone and IPad don’t indicate which zone is running. It worked great for awhile, but now having problems. The box itself is correct on which zone is running. Have sent numerous emails and tried calling multiple times with no response. Very unhappy with customer service. Any suggestions? Thanks
