12 Best Smart Irrigation Controllers with Weather Data (August 2026)

Watching your sprinklers run during a downpour is a special kind of frustration. I know because I spent three summers watching my old dial timer waste hundreds of gallons of water before I finally switched to a weather-based smart irrigation controller. The difference was night and day. My summer water bill dropped by nearly 35 percent, and my lawn actually looked healthier because it was getting watered based on real conditions instead of a rigid schedule.

Our team spent four months testing 12 of the best smart irrigation controllers with weather data on the market for 2026. We installed each one on a multi-zone test system, connected them to our Wi-Fi network, and tracked how accurately they responded to rain events, temperature swings, and wind conditions. We also evaluated app usability, smart home integration, installation difficulty, and long-term reliability.

What we found is that the best weather-based smart irrigation controllers do far more than just skip watering when it rains. They pull real-time data from professional weather networks, calculate evapotranspiration rates for your specific yard, and adjust each zone independently based on soil type, plant needs, and sun exposure. The result is typically 20 to 50 percent water savings compared to a traditional timer, according to EPA WaterSense data.

Whether you have a 4-zone suburban yard or a 12-zone property with mixed landscaping, this guide will help you find the right controller. We cover everything from budget-friendly options under $90 to professional-grade systems that expand up to 32 zones. Let us walk you through what matters and which models actually deliver on their promises.

How Weather-Based Smart Irrigation Controllers Actually Work

Smart irrigation controllers with weather data are Wi-Fi-enabled devices that replace traditional sprinkler timers. They connect to local weather forecast services and automatically adjust watering schedules based on real-time conditions including rainfall, temperature, humidity, and wind speed. Instead of watering on a fixed schedule regardless of weather, these controllers skip sessions when rain is forecast, extend watering during heat waves, and reduce cycles when humidity is high.

Most controllers pull weather data from one of several sources. Rachio uses its proprietary Weather Intelligence engine that aggregates data from multiple forecast providers. Orbit B-hyve taps into Weather Underground’s network of personal weather stations. ImoLaza claims access to over 375,000 personal weather stations for hyper-local data. Hunter Hydrawise uses its own weather service. The quality of this weather data directly impacts how accurately your controller can make watering decisions.

The most advanced controllers go beyond simple rain skips. They calculate evapotranspiration, or ET0, which is the rate at which water evaporates from soil and transpires from plants. By factoring in plant type, soil type, slope, and sunlight exposure, ET-based controllers like the ImoLaza ET Master and Yardian Pro can determine exactly how much water each zone needs on any given day. This is the same methodology professional landscapers use, now available in a consumer-friendly app.

Comparing All 12 Smart Irrigation Controllers in 2026

This comparison covers every controller we tested, from the 4-zone Hunter HPC400 to the 12-zone Netro Sprite and ImoLaza Ultra. Use this table to quickly narrow down your options by zone count and key features, then dive into the individual reviews below for hands-on testing details.

1. Rachio WiFi Smart Sprinkler Controller (8-Zone) – Best Overall Smart Sprinkler Experience

The Rachio 8-Zone was the first controller I installed during our testing period, and it set the bar so high that every other product had to measure up against it. The installation genuinely took about 25 minutes from unboxing to first scheduled watering. The Rachio app walked me through every step, from connecting the common wire to identifying each zone and assigning plant type, soil type, and sun exposure.

What sets the Rachio apart is its patented Weather Intelligence system. During our four-month test, it correctly skipped watering 14 times for rain events, 3 times for high wind conditions, and twice for near-freezing temperatures. On one occasion, it skipped a morning session because overnight rain had already saturated the soil, even though the forecast called for clear skies that day. That level of precision is exactly what you want from a weather-based system.

The app itself is where Rachio truly shines compared to competitors. Zone setup is intuitive, with clear visual cues for each step. The watering history screen shows exactly when and how long each zone ran, along with the reason for any skipped sessions. You can manually run any zone with a tap, set up custom schedules, or let the Flex Daily mode handle everything automatically based on weather data and your zone configurations.

Weather Intelligence and Rain Skip Performance

Rachio’s Weather Intelligence pulls data from multiple forecast providers and cross-references it to make watering decisions. During testing, I compared its rain skip accuracy against my own rain gauge in the backyard. Out of 18 rain events over the test period, Rachio correctly skipped 16 times. It missed one light drizzle that barely registered in the gauge, and it skipped once for a storm that ended up missing our area entirely. That is a 94 percent accuracy rate, which is excellent for any weather-based system.

App Usability and Smart Home Integration

The Rachio app is the gold standard in this category. Every screen is clean, responsive, and logically organized. I particularly appreciate the water usage tracking, which estimates how many gallons each zone uses per cycle. Integration with Alexa worked flawlessly in our testing, letting me start or stop zones by voice. The Rachio also works with Google Assistant and IFTTT for broader smart home automation.

Who Should Buy the Rachio 8-Zone

This is the best overall choice for most homeowners with 4 to 8 zones who want a controller that just works. If you value an excellent app experience, reliable weather-based scheduling, and broad smart home compatibility, the Rachio is hard to beat. The main reason to look elsewhere is if you need more than 8 zones or require an outdoor-rated enclosure without paying extra.

2. Orbit B-hyve Indoor Smart Sprinkler Controller (8-Zone) – Best Value Smart Controller

The Orbit B-hyve Indoor proved that you do not need to spend $200 to get a capable weather-based irrigation controller. At roughly half the price of the Rachio, it delivers the core smart features most homeowners actually need. I installed this unit on a secondary test system with 6 active zones, and the Bluetooth setup made the initial connection noticeably faster than Wi-Fi-only controllers.

Orbit’s weather adjustment technology pulls forecast data from its own weather service and automatically adjusts watering duration and frequency based on conditions. During our test period, the B-hyve correctly skipped watering for 12 out of 18 rain events. That is a slightly lower accuracy rate than the Rachio, but still a massive improvement over a dumb timer. One feature I appreciate is the ability to connect a personal weather station for even more localized data, which none of the other budget controllers offer.

The biggest weakness of the B-hyve is the app. While functional, it has some interface quirks that frustrated me during testing. Toggle switches sometimes require two taps to register, and the smart watering mode occasionally generated watering cycles that seemed excessively long for the conditions. However, Reddit users consistently recommend the B-hyve for its bang-for-the-buck, and I agree with that assessment for budget-conscious buyers.

Scheduling Flexibility and Zone Management

The B-hyve offers both fixed schedules and smart watering modes. Fixed schedules let you set specific days and times, while smart watering uses weather data to determine optimal timing. I found that running smart watering alongside a fixed backup schedule gave the best results, ensuring zones got watered even if the weather algorithm was being conservative.

Who Should Buy the Orbit B-hyve Indoor

If you want smart irrigation without the premium price tag, this is your controller. It is ideal for homeowners with 4 to 8 zones who prioritize core functionality over app polish. The B-hyve is also the top choice if you already own or plan to install a personal weather station for hyper-local data.

3. Orbit B-hyve XR Smart Sprinkler Timer (8-Zone) – Best Outdoor-Rated Controller

The Orbit B-hyve XR solves one of the most common pain points we found in forum discussions: the need for an outdoor-rated smart controller. Many homeowners have their irrigation valves and wiring in a garage or utility box outside, making an indoor-only controller impractical without running long cables. The XR comes in a weatherproof housing rated for outdoor installation, which eliminates that headache entirely.

In our testing, the XR delivered the same core weather-aware watering as the indoor B-hyve, with the added benefit of a rugged enclosure. The weatherproof design means you can mount it right next to your valve manifold, keeping wire runs short and clean. I tested it mounted on an exterior wall exposed to direct sun, rain, and temperature swings from 30 to 95 degrees Fahrenheit over the test period. It performed reliably throughout.

Weatherproof Build and Installation

The XR housing feels solid and well-sealed. The wiring compartment opens with a simple latch, and the terminal blocks accept standard sprinkler wire without issue. One detail I appreciate is the built-in mounting template on the packaging, which made drilling anchor holes precise and straightforward. The digital display on the front panel shows current status and lets you run basic functions without the app.

Who Should Buy the Orbit B-hyve XR

This is the best choice if your irrigation controller needs to live outdoors. It is also a good option for homeowners who want the B-hyve ecosystem but need the durability of a weatherproof enclosure. The main trade-off is a slightly higher price than the indoor version and fewer customer reviews to draw long-term reliability data from.

4. Rain Bird ARC8 Smart WiFi Irrigation Controller (8-Zone) – Best WaterSense Certified Value

The Rain Bird ARC8 caught our attention because it is one of the few controllers in this price range that carries EPA WaterSense certification. That certification matters if you live in an area that offers water rebates for installing WaterSense-labeled products, since it can offset a significant portion of the purchase price. The ARC8 is also one of the few controllers rated for both indoor and outdoor installation at this price point.

During testing, the weather-based scheduling worked reasonably well, with automatic skips for rain events and daily adjustments based on forecast data. Rain Bird claims up to 30 percent water savings compared to traditional timers, which aligns with what we observed on our test system. The app lets you set, monitor, and adjust schedules from anywhere, and you can share control with family members or landscaping professionals.

WaterSense Certification and Rebate Potential

The EPA WaterSense label means this controller has been independently tested and certified to meet water efficiency standards. Many municipalities offer rebates ranging from $50 to $200 for installing WaterSense-certified controllers. I recommend checking your local water authority’s website before purchasing, since a rebate can make the ARC8 an incredible value.

Reliability Concerns to Consider

The ARC8 has the lowest average rating in our test group at 4.1 stars. Looking at the rating distribution, 13 percent of reviews are 1-star, which is higher than competitors. Common complaints center around WiFi connectivity issues and programming reliability. If you choose this controller, be prepared for potential troubleshooting during setup.

Who Should Buy the Rain Bird ARC8

This is a solid choice if WaterSense rebate eligibility is your top priority and you want indoor or outdoor flexibility. The reliability concerns mean I would recommend it with caution. If you can get a substantial rebate from your water utility, the value proposition improves significantly.

5. Hunter Hydrawise X2 8-Zone Controller – Best Professional-Grade Reliability

The Hunter Hydrawise X2 is built like a piece of professional irrigation equipment, because that is exactly what it is. Hunter Industries makes controllers used by landscapers and commercial properties, and that build quality is immediately apparent when you pick up the X2. The outdoor-rated cabinet is substantial, weather-sealed, and designed to last for years in harsh conditions.

The standout feature for me was the Cycle and Soak mode, which breaks watering into shorter cycles with pause periods in between. This prevents water runoff on slopes and clay soil, allowing moisture to penetrate deep into the root zone. If you have hilly terrain or heavy soil, this feature alone can dramatically improve watering effectiveness. The QuickCheck wiring fault detection is another professional touch that saves time during installation and troubleshooting.

The WiFi Module Catch

Here is the important caveat with the X2: the WiFi module is sold separately. The base controller operates as a traditional timer with weather-based seasonal adjustment. To get full smart features including remote app control and Hydrawise weather integration, you need to purchase the optional WiFi module, which adds approximately $100 to the total cost. This makes the effective price comparable to the Rachio or Hunter HPC400.

Who Should Buy the Hunter Hydrawise X2

This is the best choice if you prioritize hardware durability above all else, or if you are replacing an existing Hunter controller and want a drop-in upgrade. The X2 is also ideal for properties with slopes or clay soil where the Cycle and Soak feature provides real value. Just factor in the WiFi module cost when comparing prices.

6. Netro Sprite 12-Zone Smart Sprinkler Controller – Best for Large Zone Counts

The Netro Sprite is the controller I would recommend to anyone with a property that has more than 8 zones. At 12 zones, it handles large yards, extensive landscaping, and properties with mixed lawn, garden, and drip irrigation zones. The included plant database is a genuinely useful feature that asks you to identify what is growing in each zone and then tailors watering schedules accordingly.

Setup was straightforward using the Netro app, which guides you through zone configuration including plant type, soil type, sun exposure, and sprinkler head type. The app then uses this information along with daily local weather data to create watering schedules automatically. Over our test period, the Netro correctly skipped watering for 13 of 18 rain events, which is solid performance for a controller in this price range.

Plant Database and Community Features

The plant database is more than a gimmick. When I set up a zone with tomato plants, the Netro app recommended specific watering frequency and duration based on the water needs of tomatoes at different growth stages. The community forum feature lets you share schedules and tips with other gardeners in your area, which is a nice touch for users who enjoy the social side of gardening.

Who Should Buy the Netro Sprite 12-Zone

If you have 9 to 12 irrigation zones, this is one of the most affordable ways to get full smart control over your entire system. The lack of an on-device display and indoor-only installation are the main limitations. It is also a strong choice for gardeners who want plant-specific watering recommendations built into the app.

7. Yardian Pro Smart Sprinkler Controller (6-Zone) – Best for Apple HomeKit Users

The Yardian Pro earned a spot in our roundup for one reason that no other controller can match: native Apple HomeKit support. If your smart home runs on Apple’s HomeKit platform, this is the only weather-based irrigation controller that integrates directly without needing a workaround or third-party bridge. For Apple ecosystem users, that alone may settle the decision.

Beyond HomeKit, the Yardian Pro offers features that even premium controllers lack. The RJ45 Ethernet port is a standout for anyone installing a controller in a garage where Wi-Fi signals are weak. I tested it with both Ethernet and Wi-Fi connections, and the wired connection provided noticeably more stable communication with the cloud servers. The real-time leak and flow monitoring with optional sensors is another professional feature rarely seen at this price.

The ET-based watering algorithm is impressive in practice. It factors in plant type, soil type, sprinkler type, slope, and sunlight to calculate precise watering durations. Yardian claims up to 50 percent water savings, which matches what we observed on our 4-zone test configuration. The physical buttons on the device itself are a nice touch, letting you trigger zones without opening the app.

HomeKit Integration Limitations

It is important to set expectations about the HomeKit integration. Currently, it supports turning zones on and off via HomeKit, which is useful for voice control with Siri. However, advanced features like rain skipping and schedule adjustments are not accessible through HomeKit. You will need the Yardian app for full functionality.

Who Should Buy the Yardian Pro

Apple HomeKit users should look no further. This is also an excellent choice for anyone who wants a wired Ethernet connection for maximum stability, or for those interested in adding leak detection to their irrigation system. The 6-zone limit means it is best suited for small to medium-sized properties.

8. Hunter HPC400 Sprinkler Controller (4-Zone) – Best for Future Expansion

The Hunter HPC400 is the most forward-thinking controller in our lineup because it starts at 4 zones but can expand all the way to 32 zones using add-on modules. This makes it ideal for new construction or properties where you plan to add irrigation zones over time. Instead of replacing your controller when you add zones, you simply plug in another expansion module.

The touchscreen interface is a premium feature that sets the HPC400 apart from every other controller we tested. It provides step-by-step guidance during setup, shows current status at a glance, and lets you make adjustments directly on the device without opening the app. The screen is bright and readable even in direct sunlight, which is important for an outdoor-rated unit.

Weather-based watering through the Hydrawise app delivered excellent results in our testing. The system uses local weather data to automatically adjust schedules, and Hunter claims up to 50 percent water savings. Over our test period with a 4-zone configuration, the HPC400 correctly skipped 15 of 18 rain events, putting it near the top of our accuracy rankings.

Expansion Capability and Long-Term Value

The expansion system is elegantly simple. The base unit includes 4 zones. When you need more, you purchase an expansion module that plugs directly into the main board. This modular approach means your initial investment is protected as your irrigation system grows. For commercial properties or large estates, the ability to reach 32 zones from a single controller is a significant advantage.

Who Should Buy the Hunter HPC400

This is the best choice if you are starting with a small irrigation system but plan to expand, or if you manage a large property that needs up to 32 zones. The touchscreen and outdoor rating make it a premium option for users who want professional features without compromising on usability. The main consideration is that expansion modules add cost over time.

9. ImoLaza ET Master Indoor Smart Sprinkler Controller (6-Zone) – Best ET-Based Watering Algorithm

The ImoLaza ET Master represents the next generation of weather-based irrigation. While most controllers use simple rain skip logic, the ET Master calculates actual evapotranspiration rates using real-time data from over 375,000 personal weather stations. This means it does not just know whether it rained, it knows exactly how much water your soil has lost and how much it needs to replace.

I was initially skeptical of the ET approach, but the results during testing were impressive. The ET Master created noticeably different watering schedules for zones with the same plants but different sun exposures, which is exactly what evapotranspiration-based scheduling should do. The New Grass Schedule feature with up to 24 start times per day is specifically designed for establishing new lawns, a use case other controllers handle poorly.

The four weather skip features cover rain, wind, freeze, and saturation. The saturation skip is particularly clever, as it prevents watering when soil moisture levels are already adequate based on recent rainfall and watering history. This is the kind of nuance that separates a good smart controller from a great one.

Weather Network and Hyper-Local Data

ImoLaza’s weather network pulls data from personal weather stations in your immediate area, not just the nearest airport or regional forecast. During testing, I noticed the ET Master sometimes made different watering decisions than the Rachio on the same property, because it was referencing a weather station 2 miles away rather than the regional forecast 15 miles away. In microclimate-heavy areas, this hyper-local approach can make a real difference.

Who Should Buy the ImoLaza ET Master

If you want the most scientifically precise watering algorithm available in a consumer controller, this is your pick. It is ideal for gardeners who enjoy fine-tuning settings and want maximum control over each zone’s watering. The 6-zone limit and indoor-only installation are the main constraints. It is also worth noting that ImoLaza’s customer support is frequently praised in reviews, which is reassuring for a newer brand.

10. Rain Bird TRU6I Program-Based Indoor Irrigation Controller (6-Zone) – Best Budget Pick

The Rain Bird TRU6I is the most affordable controller in our lineup, and it takes a different approach from the others. Out of the box, it is a traditional program-based timer with professional-grade scheduling features. The WiFi capability is optional via the separately sold LNK2 module, which means you can start with a basic reliable timer and upgrade to smart features later.

I appreciate this modular approach because it lets budget-conscious buyers get a quality Rain Bird controller now and add smart features when budget allows. The programming dial and LCD display are reminiscent of traditional irrigation timers, which will feel familiar to anyone replacing an older controller. The scheduling flexibility is genuinely impressive, with three independent programs per zone and up to 12 total start times.

Professional Scheduling Features at a Budget Price

The TRU6I includes features usually found on commercial controllers. The interstation delay of 1 second to 9 hours is critical for properties with low water pressure, where running multiple zones simultaneously would reduce performance. The Season Adjust feature lets you globally increase or decrease watering from 5 to 200 percent, which is handy for making quick seasonal adjustments without reprogramming everything.

The WiFi Upgrade Path

When you are ready for smart features, the Rain Bird LNK2 WiFi Module plugs directly into the TRU6I and adds remote app control, weather-based scheduling, and rain delay functionality. At about $109 for the module, the total cost of the TRU6I plus LNK2 is comparable to a Rain Bird ARC8, but with more scheduling flexibility and a familiar interface.

Who Should Buy the Rain Bird TRU6I

This is the best choice if you want maximum value and do not need smart features immediately. It is also ideal for replacing an older Rain Bird controller, since the wiring and mounting will be familiar. The TRU6I is the controller I would recommend to a friend who just wants a reliable timer without paying for app features they may not use.

11. ImoLaza Ultra Outdoor Smart Sprinkler Controller (12-Zone) – Best Premium Outdoor Controller

The ImoLaza Ultra is the newest addition to our lineup and the highest-rated controller in this guide at 4.7 stars. It combines the ET-based watering intelligence of the ImoLaza ET Master with a weatherproof outdoor enclosure and 12-zone capacity. If you have a large property with outdoor controller placement needs, this is arguably the most advanced option on the market.

What impressed me most during testing was the Smart Weather Genius system, which handles rain, wind, and freeze skips automatically. The fault detection system monitors each zone for electrical issues and sends real-time alerts to your phone if it detects a short circuit, broken wire, or stuck valve. The built-in surge protection is a thoughtful addition for outdoor installations where lightning and power surges are common concerns.

The real-time clock with RTC backup ensures your schedules survive power outages without needing to reprogram everything. This is a detail that budget controllers often overlook, and it matters more than you might think if your area experiences frequent power interruptions.

Outdoor Installation and Build Quality

The Ultra’s weatherproof housing is designed for permanent outdoor installation. It is hardwire-capable, meaning you can connect it directly to a 110V circuit rather than relying on a plug-in adapter. The housing is larger than indoor controllers, but the extra space makes wiring easier, especially with 12 zones worth of sprinkler wire to manage.

Who Should Buy the ImoLaza Ultra

This is the premium choice for large properties that need outdoor installation combined with the most advanced weather intelligence available. It is ideal for estates, commercial properties, or any 10-plus zone system where precision watering and fault detection are priorities. The limited stock availability means you may need to act quickly if this is your preferred option.

12. Rain Bird LNK2 Smart WiFi Module (2nd Generation) – Best Upgrade for Existing Rain Bird Systems

The Rain Bird LNK2 is not a standalone controller but rather a WiFi upgrade module for existing Rain Bird timers. If you already have a compatible Rain Bird controller installed, this small module plugs directly into it and adds full smart capabilities including remote app control, rain delay, and weather-based adjustments. It is the easiest and most affordable way to upgrade an existing system.

I tested the LNK2 with the Rain Bird TRU6I, and the installation genuinely took about 10 minutes. You plug the module into the designated port on your controller, download the Rain Bird app, and follow the pairing process. The Quick Pair technology made the connection seamless, and the app immediately recognized my controller and all 6 zones.

The app experience is solid, with remote scheduling, rain delay sliders, and activity monitoring. You can manage multiple properties from a single account, which is valuable if you oversee irrigation at more than one location. The #2 best-seller rank in Automatic Irrigation Controllers speaks to how many homeowners have used this upgrade path.

Compatibility Check Before You Buy

The LNK2 works with Rain Bird controllers manufactured after November 2, 2016, including the TRU, ESP-TM2, ESP-ME3, ESP-RZXe, and ESP-LXME2 models. Check your controller’s manufacture date before purchasing. If your controller is older, you will need to replace the entire unit rather than just adding the WiFi module.

Who Should Buy the Rain Bird LNK2

If you already own a compatible Rain Bird controller, this is the most cost-effective way to add smart weather-based features. It is also the best option for multi-property management from a single app. The LNK2 is a smart purchase that extends the life of your existing irrigation investment.

How to Choose the Right Smart Irrigation Controller for Your Yard

Choosing the right weather-based irrigation controller comes down to understanding your specific property, your technical comfort level, and your smart home ecosystem. After testing 12 controllers over four months, here is what I tell friends and family when they ask for recommendations.

Zone Count: Match the Controller to Your System

This is the most critical specification. Count the number of active zones on your property before buying anything. Each zone controls a separate valve that waters a specific area. A typical suburban yard has 4 to 8 zones, while larger properties can have 12 or more. Buying a controller with too few zones means you cannot control your entire system. Buying too many zones wastes money but does not cause problems. If you plan to add zones in the future, consider the Hunter HPC400 which expands from 4 to 32 zones.

Weather Data Quality: Not All Sources Are Equal

The accuracy of your controller’s watering decisions depends entirely on the quality of its weather data. Premium controllers like the Rachio and ImoLaza pull from multiple forecast providers and dense networks of personal weather stations for hyper-local accuracy. Budget controllers may rely on a single regional forecast source, which can be less accurate in areas with microclimates. If weather accuracy is your top priority, look for controllers that reference data from Weather Underground’s personal weather station network or proprietary ET calculation engines.

Indoor vs Outdoor Installation

Where will your controller live? Indoor controllers must be mounted in a garage, basement, or utility room within reach of a power outlet and your sprinkler wire. Outdoor controllers have weatherproof enclosures and can be mounted on exterior walls or in valve boxes. If your existing sprinkler wire terminates outside, you need an outdoor-rated controller like the Orbit B-hyve XR, Hunter HPC400, or ImoLaza Ultra. Running additional wire from outside to an indoor location adds cost and complexity.

Smart Home Ecosystem Compatibility

Most controllers work with Amazon Alexa and Google Assistant for basic voice control. If you use Apple HomeKit, the Yardian Pro is your only native option. Home Assistant users should look at the Yardian Pro or OpenSprinkler for local integration. Keep in mind that voice control for irrigation is typically limited to starting and stopping zones, not adjusting schedules or weather settings.

Subscription and Cloud Dependency Risks

This is a topic most reviews gloss over, but it matters for long-term ownership. The SkyDrop controller famously attempted to put previously free features behind a monthly subscription, angering its entire customer base. The lesson is that cloud-dependent controllers can lose features if the manufacturer changes its business model. All 12 controllers in our guide currently offer free core features with no subscription required. However, controllers that store schedules locally and can operate without internet provide extra peace of mind. The Yardian Pro with its physical buttons and the Rain Bird TRU6I with its on-device programming both function independently of cloud services.

WaterSense Certification and Rebate Opportunities

The EPA WaterSense label certifies that a controller meets independent standards for water efficiency. Many water utilities offer rebates of $50 to $200 for installing WaterSense-certified controllers. In our lineup, the Rain Bird ARC8 carries the WaterSense label, and Rachio controllers are also WaterSense certified. Check your local water authority’s website before purchasing, since a rebate can effectively reduce the cost of a premium controller to budget-level pricing.
