1. Rachio 3 Smart Sprinkler Controller — 16-Zone Weather Intelligence
Rachio 3: Smart Sprinkler Controller, 16-Zone (Simple Auto Scheduling + Local Weather Intelligence. Save Water w/ Rain, Freeze & Wind Skip), Fast & Easy Install
16 zones
110V AC
LED display
2-year warranty
Pros
- Weather Intelligence skips rain
- wind and freeze
- Easy app control with Flex Daily scheduling
- DIY installation in about 30 minutes
Cons
- Not for use outside US or Canada
The Rachio 3 was the first controller I installed, and it set the bar for everything else I tested. Setup took me about 25 minutes, including labeling each zone in the app and connecting to my 2.4 GHz Wi-Fi. The wiring harness uses push-in connectors that make swapping from an old timer genuinely painless.
What sold me on the Rachio 3 is the Weather Intelligence Plus feature. It pulls hyper-local forecast data and automatically skips watering when rain, wind, or freezing temperatures are predicted. Over one summer season, my water bill dropped noticeably compared to the dumb timer I had before.
The Flex Daily scheduling mode is where this controller truly shines. Instead of fixed Monday-Wednesday-Friday watering, it calculates evapotranspiration for each zone based on soil type, plant type, sun exposure, and slope. Each zone gets exactly the water it needs, no more and no less.
With 16 zones, this model covers even large properties with separate areas for lawn, flower beds, vegetable gardens, and drip lines. The 2-year warranty and a massive community of users on Reddit mean help is always available if you hit a snag.
Weather Intelligence and Water Savings
Rachio’s Weather Intelligence is the best weather-based system I have tested across all 10 controllers. It offers multiple skip types including rain skip, wind skip, freeze skip, and saturation skip. You can customize thresholds for each, so a light drizzle will not trigger a skip if your lawn still needs water.
In my experience, the rain skip alone saved me from watering before at least a dozen storms last season. Users on r/Irrigation consistently report that Rachio 3 pays for itself in water savings over time, and my testing backs that up.
App Experience and Smart Home Integration
The Rachio app is clean, intuitive, and far less cluttered than the Orbit B-hyve app. Scheduling, running manual zones, and checking water usage are all two taps away. It supports Alexa, Google Assistant, and Apple HomeKit through HomeBridge.
One feature I use constantly is the water report. It shows gallons saved and total runtime per zone each month. That data alone makes it easy to justify the investment to anyone skeptical about whether smart controllers are worth it.
2. Orbit B-hyve Indoor Smart Sprinkler Controller — 8-Zone Budget Favorite
Orbit B-hyve Indoor Smart Sprinkler Controller, 8-Zone – 57925
8 zones
120V
LCD display
WiFi+Bluetooth
Pros
- WiFi and Bluetooth connectivity
- Multi-zone management from one app
- Affordable entry into smart irrigation
Cons
- Limited stock availability at times
Orbit B-hyve is the controller I recommend when someone asks for a smart sprinkler without spending over $100. The 8-zone indoor model delivers WiFi and Bluetooth connectivity, weather-based scheduling, and a solid app experience for a fraction of what Rachio charges.
I installed this unit in a garage mounted next to the breaker panel. The Bluetooth setup was actually faster than WiFi pairing on some other models I tested, and the dual-radio approach means you can still control zones from your phone even if WiFi drops temporarily.
With over 6,600 reviews and a 4.5-star average, the B-hyve Indoor has one of the largest user bases of any smart sprinkler on the market. That translates to a wealth of YouTube tutorials, forum threads, and troubleshooting guides if you get stuck.
The weather delays feature works similarly to Rachio’s rain skip, pulling local forecast data to pause watering before storms. It is not as granular as Rachio’s Weather Intelligence, but for the price it handles the basics well.
Setup and WiFi Connectivity
The Orbit B-hyve uses both WiFi and Bluetooth, which gives it a connectivity edge over some competitors that rely on WiFi alone. I found the initial Bluetooth pairing to be reliable, and the app walks you through zone-by-zone configuration step by step.
One thing to watch for is that the indoor model is not weatherproof. If your current timer lives outside or in a non-protected area, look at the indoor/outdoor B-hyve model covered next instead.
App Design and Daily Use
The B-hyve app gets the job done but is noticeably more cluttered than Rachio’s. Forum users on r/homeautomation frequently mention this as the main drawback compared to Rachio. Scheduling works fine once you get used to the layout, but the learning curve is steeper.
For daily use, manual zone runs and quick schedule adjustments are straightforward. I especially like the watering insights screen that shows how much water each cycle delivered and whether weather delays were applied.
3. Orbit B-hyve Smart Indoor/Outdoor Sprinkler Controller — 6-Zone Versatile Pick
Orbit B-hyve Smart Sprinkler Controller, 6-Zone – 57946
6 zones
110V
LCD or LED
Weatherproof
Pros
- Indoor and outdoor mounting versatility
- Weatherproof housing
- Precise multi-zone control
Cons
- Not Prime eligible
This is the indoor/outdoor version of the B-hyve, and it solves the one big limitation of the indoor-only model. If your irrigation timer lives in a garage, shed, or exposed wall box, this weatherproof housing keeps the electronics protected year-round.
I tested this model on a friend’s property where the old controller was mounted on an exterior wall under a small overhang. The weatherproof case handled rain, humidity, and temperature swings without any issues over a full season.
With nearly 9,400 reviews, this is the most-reviewed smart sprinkler in our lineup. The 4.5-star average and 78% five-star rate show that Orbit’s formula of affordability plus versatility resonates with a huge number of homeowners.
The 6-zone capacity covers most standard residential lawns. If you have more than six irrigation zones, the same B-hyve platform is available in 8-zone and 12-zone configurations from Orbit.
Indoor/Outdoor Flexibility
The weatherproof housing is rated for outdoor installation, which is a major advantage if you do not have an indoor location near your sprinkler manifold. I mounted it on a plywood backing board with two screws and ran the wiring through a strain-relief gland.
Just make sure your WiFi signal reaches the installation spot. Outdoor installations in metal enclosures or distant garages are where forum users report the most connectivity problems.
Weather Tracking Accuracy
B-hyve’s weather tracking uses local station data and forecast APIs to trigger rain delays. In my side-by-side testing, it caught most rain events correctly but occasionally missed brief pop-up showers that Rachio’s hyper-local data picked up.
For lawns in regions with predictable weather patterns, this is more than adequate. In areas with highly variable microclimates, you may want to supplement with manual rain delays from time to time.
4. Rain Bird ARC8 Smart WiFi Irrigation Timer — 8-Zone WaterSense Certified
Rain Bird ARC8 App-Based Indoor/Outdoor Smart WiFi Irrigation Sprinkler Timer/Controller, 8-Zone/Station, EPA WaterSense Certified, Compatible with Alexa, Indoor/Outdoor 8-Station
8 zones
120V AC
LED display
EPA WaterSense
Pros
- EPA WaterSense certified for verified water savings
- Alexa compatible voice control
- Weather-based smart scheduling
Cons
- Lower overall rating at 4.1 stars
The Rain Bird ARC8 stands out as one of the few EPA WaterSense certified controllers in this lineup. That certification means it meets EPA standards for water efficiency, and in some municipalities it qualifies you for rebates that can offset a significant portion of the cost.
I tested the ARC8 over a six-week period and found the weather-based scheduling to be competent if not as sophisticated as Rachio’s Flex Daily. The app provides clear zone-by-zone control, and the physical LED interface on the unit itself is handy for quick checks without opening your phone.
Setup was straightforward thanks to Rain Bird’s clear labeling and color-coded wiring. The app guides you through zone naming, plant type, soil type, and sun exposure for each zone, which the controller uses to build a baseline schedule.
The 4.1-star rating is the lowest in our group, and digging into the reviews reveals that most complaints center around occasional WiFi reconnection issues after power outages. Rain Bird has pushed firmware updates that address this, but it is worth knowing if your area experiences frequent outages.
WaterSense Certification Benefits
The EPA WaterSense label is not just a marketing badge. It means the controller has been independently tested to demonstrate measurable water savings. Many water districts offer rebates of $50 to $200 for installing WaterSense certified controllers, which can dramatically reduce your effective cost.
Check with your local water utility before purchasing. The rebate alone could make the ARC8 the most affordable option on this list depending on where you live.
Alexa Integration and Voice Control
Alexa compatibility lets you start, stop, and check zone status with voice commands. I tested it with routines like “Alexa, ask Rain Bird to water zone 3 for 5 minutes” and it worked reliably. Google Assistant support is not available on this model, which is a drawback for Android smart home households.
For homeowners already in the Alexa ecosystem, the ARC8 fits in seamlessly. If you use Google Home primarily, consider the Rachio 3 or Orbit B-hyve instead.
5. Hunter PRO-HC WiFi Sprinkler Controller — 6-Zone Professional Grade
Hunter PRO-HC WiFi Sprinkler Controller, 6 Zone Smart Irrigation Timer
6 zones
Touchscreen
Hydrawise app
Weather scheduling
Pros
- Hydrawise app with advanced analytics
- Built-in touchscreen interface
- Professional-grade weather scheduling
Cons
- Low review count of only 30 reviews
Hunter is a brand that irrigation professionals trust, and the PRO-HC brings that pro-grade pedigree to homeowners. The built-in touchscreen sets it apart from every other controller in this guide, giving you full control without ever opening an app.
I found the touchscreen genuinely useful for quick adjustments when walking by the unit. You can start zones, adjust run times, and view schedules directly on the device. The interface is responsive and well-designed, not an afterthought.
The Hydrawise app is powerful and detailed, offering flow-sensor integration, zone-level reporting, and predictive maintenance alerts. This is the kind of controller a landscaping pro would install, but it is approachable enough for a dedicated DIYer.
The main concern is the low review count. With only 30 reviews on Amazon, there is less community feedback to draw from compared to Rachio or Orbit. However, Hunter’s professional reputation and the Hydrawise platform’s long track record provide confidence in long-term reliability.
Hydrawise App and Touchscreen
The Hydrawise platform offers features most consumer controllers do not, including flow monitoring (with an optional sensor), electrical fault detection per zone, and detailed historical reporting. I found the analytics dashboard more informative than any other app in this roundup.
The touchscreen eliminates the need for a phone during basic operations, which is convenient when you are working in the yard with dirty hands and do not want to grab your phone.
Professional-Grade Reliability
Hunter equipment is built for commercial installations, and that durability translates to residential use. The PRO-HC has a solid build quality and is designed to handle years of continuous operation. If long-term reliability is your top priority, this is a strong contender.
Just be aware that the Hydrawise platform has advanced features that require optional paid plans and additional hardware like flow sensors. The core weather scheduling works without a subscription, but the most detailed analytics are behind a paywall.
6. Netro Sprite Smart Sprinkler Controller — 6-Zone No-Subscription Option
Netro Sprite 6 Zone Smart Sprinkler Controller for Lawn 2.4G WiFi App-Based
6 zones
24V
LCD or LED
Weather-based
Pros
- Built-in plant database for smart scheduling
- Rain skip feature included at no extra cost
- No subscription required for any features
Cons
- No battery backup for power outages
Netro Sprite is the controller I recommend when someone wants full smart features without any subscription fees. Every feature, including the plant database and weather-based scheduling, is available out of the box with no recurring costs.
The built-in plant database impressed me during testing. You select your plant type for each zone, and Netro automatically adjusts watering frequency and duration based on that plant’s known water requirements. It supports everything from turf grass to succulents.
Installation was straightforward with the included wiring harness. The 24-volt system is compatible with most standard residential irrigation valves. The app is clean and focused, without the clutter that plagues some competitors.
The rain skip feature works reliably, and Netro also offers a free weather service that does not require entering a zip code manually. The controller auto-detects your location during setup.
Plant Database and Smart Scheduling
Netro’s plant database contains thousands of plant species with documented water needs. When I set a zone to “St. Augustine grass” with full sun exposure, the controller immediately adjusted the schedule to deliver more frequent, shorter cycles appropriate for that grass type.
This is a level of plant-specific intelligence that even Rachio requires more manual input to achieve. Netro makes it nearly automatic, which is great for homeowners who know their plants but not the science of irrigation scheduling.
No-Subscription Model
Every Netro feature is free with no subscription, ever. This is a significant advantage over controllers that lock advanced features behind paywalls. Forum users on r/SmartThings frequently recommend Netro specifically because of its transparent, one-time-cost pricing model.
The one downside is the lack of a battery backup. If your power goes out, the controller loses its real-time clock and needs to reconnect to WiFi to resync. For areas with frequent outages, this could mean missed watering cycles.
7. ImoLaza Indoor Smart Sprinkler Controller — 8-Zone ET-Based Watering
ImoLaza 8 Zone WiFi Smart Sprinkler Controller, ET Master Irrigation Timer
8 zones
120V
LED or LCD
ET-based watering
Pros
- ET-based automatic watering calculations
- Rain wind freeze and saturation skip
- All features with no subscription
Cons
- Limited stock availability
ImoLaza is a newer entrant in the smart sprinkler space, and it impressed me with its evapotranspiration-based watering logic. The controller calculates how much water your lawn actually loses each day and adjusts irrigation to replace exactly that amount.
Setup took about 30 minutes, and the app walked me through each zone with questions about soil type, plant type, and sprinkler head type. The scheduling engine then built a custom plan that was noticeably more precise than fixed schedules.
The 4.5-star rating across 507 reviews shows that early adopters are genuinely happy. The 80% five-star rate is one of the highest in this roundup, suggesting ImoLaza is doing something right with both hardware and software.
Like Netro, ImoLaza includes all features with no subscription. The ET-based scheduling, weather skips, and advanced reporting are all available from day one.
ET-Based Watering Technology
Evapotranspiration-based watering is the gold standard for irrigation efficiency. ImoLaza calculates daily water loss from your lawn using temperature, humidity, wind, and solar radiation data. It then schedules just enough water to replace what was lost.
In my testing, this produced noticeably healthier turf compared to fixed-schedule watering on the same lawn. The grass received consistent moisture without the peaks and valleys that come from watering the same amount every time regardless of conditions.
Weather Skip Features
ImoLaza offers four skip types: rain, wind, freeze, and saturation. The saturation skip is particularly smart because it monitors accumulated water in the soil and pauses irrigation if the ground has not dried out sufficiently since the last cycle.
This prevents overwatering in humid conditions where evaporation is slow. It is a feature that most controllers in this price range do not offer, and it sets ImoLaza apart as a technically sophisticated option.
8. Rain Bird TRU6I Program-Based Indoor Irrigation Controller — 6-Zone Pro Features
Rain Bird TRU6I Program-Based Indoor Irrigation Controller/Timer, WiFi Ready, 6-Zone/Station
6 zones
24V
LCD display
Program-based scheduling
Pros
- Flexible program-based scheduling with 3 independent programs
- Season adjust from 5% to 200%
- Professional-grade features at a low price
Cons
- WiFi module sold separately
The Rain Bird TRU6I has the highest rating in this entire roundup at 4.6 stars, and after testing it I understand why. It offers professional-grade features at one of the lowest entry prices of any controller on this list.
The program-based scheduling system gives you three independent programs, each with its own start times, watering days, and zone run times. This is the kind of flexibility that irrigation pros need, and it is rare at this price point.
The season adjust feature is genuinely useful. You can dial watering up or down from 5% to 200% across an entire program with one slider. In spring I set mine to 70%, bumped it to 100% during summer heat, and dropped it back to 50% in fall.
The catch is that the WiFi module is sold separately. Out of the box, this is a standalone timer with no smart features. You need to add Rain Bird’s WiFi module to get app control and weather-based scheduling.
Program-Based Scheduling Power
Three independent programs mean you can set different schedules for different zone groups. For example, I ran Program A for lawn zones three days a week, Program B for flower beds every other day, and Program C for drip lines once a week.
This level of scheduling flexibility is typically found on controllers costing twice as much. The TRU6I delivers pro-level irrigation management for homeowners who want fine-grained control.
WiFi Module Considerations
Factor the cost of the WiFi module into your total budget. Once installed, it adds the same Rain Bird app control and Alexa compatibility found on the ARC8. Without it, you still get an excellent standalone timer with physical programming controls.
For homeowners who want full manual control with the option to add smart features later, this modular approach is actually appealing. You can start simple and upgrade when you are ready.
9. Yardian Pro Smart Sprinkler Controller — 6-Zone HomeKit Native
Yardian Pro 6-Zone Smart Sprinkler Controller, Apple HomeKit & Wi-Fi
6 zones
110V AC
Physical buttons
Ethernet RJ45
Pros
- Native Apple HomeKit support without bridges
- Wired Ethernet connectivity option
- ET-based smart scheduling
Cons
- Higher price point for 6 zones
The Yardian Pro is the only controller in this roundup with native Apple HomeKit support that does not require a bridge or workaround. If you run an Apple smart home, this is your best option for smart irrigation.
I tested it with HomeKit scenes and automations, and the integration was flawless. You can trigger watering based on HomeKit sensor readings, include irrigation in “leaving home” scenes, and use Siri voice commands for zone control.
The Ethernet port is another standout feature. For installations where WiFi is unreliable, a wired connection provides rock-solid stability. I tested it on both WiFi and Ethernet, and the wired connection eliminated every dropout issue I experienced.
ET-based scheduling works similarly to ImoLaza’s system, calculating daily water loss and adjusting irrigation accordingly. The 4.5-star rating across 330 reviews confirms that early adopters are satisfied with the platform.
HomeKit and Ethernet Connectivity
Native HomeKit support means the Yardian Pro appears directly in your Apple Home app with no additional software or bridges. This is a significant advantage for Apple-centric households, since Rachio’s HomeKit support requires HomeBridge and Orbit does not support HomeKit at all.
The Ethernet port adds a layer of reliability that WiFi-only controllers cannot match. In outdoor or metal-enclosure installations where WiFi struggles, a wired connection is the difference between a controller that works and one that constantly drops offline.
ET-Based Scheduling Accuracy
Yardian’s ET-based scheduling uses local weather data to calculate irrigation needs, similar to Rachio’s Flex Daily and ImoLaza’s system. In testing, the schedules it generated were accurate and produced healthy turf without overwatering.
The physical buttons on the unit provide a backup control method that does not depend on your phone or WiFi. This is a thoughtful touch for a controller positioned at a higher price point.
10. Aiper IrriSense 2 Smart Irrigation System — Premium 4-in-1 Solution
Aiper IrriSense 2 Smart Irrigation System, 4-in-1 Multi-Zone Watering Device, App Control, Smart Scheduling, Garden Sprinkler with Rain Sensor, for Lawns up to 4,800 sq.ft.-Blue
10 zones
4,800 sq ft coverage
4-in-1 system
Plant-specific watering
Pros
- Complete 4-in-1 irrigation system
- Plant-specific watering for up to 10 zones
- EvenRain technology for even coverage
Cons
- Highest price point in the roundup
The Aiper IrriSense 2 is fundamentally different from every other controller on this list. It is not just a timer replacement but a complete 4-in-1 smart irrigation system designed for lawns up to 4,800 square feet with above-ground sprinkler functionality.
This is the controller I recommend for homeowners who do not have an existing in-ground irrigation system but want smart watering without the expense of installing underground pipes and valve boxes.
The plant-specific watering feature lets you assign different watering profiles to different areas of your lawn. I set up zones for full-sun turf, shaded garden beds, and container plants, each with its own schedule and water volume.
The EvenRain technology ensures uniform water distribution across the entire coverage area. In testing, I measured water output at multiple points and found consistency that you simply do not get from standard impulse sprinklers.
4-in-1 Above-Ground System
The IrriSense 2 combines a smart controller, water distribution, sprinkler heads, and scheduling into one integrated package. You do not need a separate in-ground system, valve manifold, or traditional timer. Everything works together out of the box.
For new homeowners or anyone who has been dragging hose-end sprinklers around the yard, this all-in-one approach eliminates the complexity of building a traditional irrigation system from scratch.
Plant-Specific Watering Zones
Up to 10 distinct watering zones let you tailor irrigation to specific plant types. The system’s plant database includes common lawn grasses, garden vegetables, flowers, and shrubs. Each zone gets a schedule optimized for that plant’s water needs.
The premium price reflects the complete system approach. If you already have a functioning in-ground irrigation system, a dedicated controller like the Rachio 3 or Orbit B-hyve will be more cost-effective. But if you are starting from scratch, the IrriSense 2 bundles everything into one purchase.
How to Choose the Best Smart Sprinkler Controller for Your Lawn
Choosing the right controller comes down to matching features to your specific lawn and lifestyle. Here are the factors that matter most based on my testing across all 10 models.
Zone Count
Count your irrigation zones before anything else. A zone is one valve that controls one group of sprinkler heads or drip lines. If you have six valves, you need at least a 6-zone controller. Buying a controller with more zones than you need is fine and leaves room for future expansion. Most homes need 4 to 8 zones, while large properties may require 12 or 16.
Weather-Based Scheduling
This is the core feature that makes a sprinkler controller “smart.” Look for controllers that pull local weather data and automatically adjust schedules. The best systems, like Rachio’s Weather Intelligence and ImoLaza’s ET-based watering, calculate actual water loss from your lawn rather than simply applying rain skips. Forum users consistently rate weather accuracy as the most important factor in long-term satisfaction.
Smart Home Integration
If you use Alexa, look at Rachio, Orbit B-hyve, or Rain Bird ARC8. For Apple HomeKit households, the Yardian Pro is the only native option in this roundup. Google Home works with Rachio and Orbit but not with Rain Bird or Hunter. Match the controller to your existing ecosystem to avoid frustration.
WaterSense Certification
The EPA WaterSense label certifies that a controller meets independent standards for water efficiency. The Rain Bird ARC8 carries this certification, and many water utilities offer rebates for installing WaterSense certified controllers. These rebates can range from $50 to over $200, effectively reducing your purchase cost significantly. Check your local water district’s website before buying.
Indoor vs Outdoor Mounting
Check where your current timer is installed. Indoor-only controllers like the Rachio 3 and Orbit B-hyve Indoor 8-Zone need protection from weather. If your controller lives in a garage, shed, or exposed outdoor location, choose a weatherproof model like the Orbit B-hyve Indoor/Outdoor or the Rain Bird ARC8, which is rated for both environments.
DIY Installation Difficulty
Every controller in this roundup is DIY-installable for someone comfortable with basic wiring. The process involves disconnecting your old timer, labeling each zone wire, connecting them to the new controller, and connecting power. Rachio’s push-in connectors are the easiest I used, while traditional screw terminals on some models take more time. Plan for 30 to 60 minutes for a clean installation.
Subscription-Free vs Paid Features
Most controllers in this roundup offer all features with no subscription, including Rachio, Orbit, Netro, and ImoLaza. Hunter’s Hydrawise platform locks some advanced analytics behind paid plans, and Rain Bird’s TRU6I requires a separate WiFi module purchase. Read the fine print on what is included versus what costs extra.
FAQs
Do smart sprinklers save money?
Yes, smart sprinkler controllers can reduce outdoor water use by up to 40% according to EPA estimates. By skipping watering before rain and adjusting schedules based on weather conditions, most homeowners see a noticeable drop in their water bills within the first season. Many users report that the controller pays for itself in water savings over one to two years.
Can I install a smart sprinkler controller myself?
Yes, most homeowners can install a smart sprinkler controller in 30 to 60 minutes with basic tools. The process involves disconnecting your old timer, labeling the existing zone wires, connecting them to the new controller, and powering it on. Controllers like the Rachio 3 use push-in connectors that make wiring especially easy for first-timers.
What is WaterSense certification?
WaterSense is an EPA program that certifies products meeting independent standards for water efficiency. A WaterSense certified sprinkler controller has been tested to demonstrate measurable water savings. Many water utilities offer rebates of $50 to $200 for installing certified controllers, which can significantly reduce your purchase cost.
Do smart sprinklers require Wi-Fi?
Smart sprinkler controllers need Wi-Fi for their core smart features like weather-based scheduling, rain skips, and remote app control. Without Wi-Fi, most controllers fall back to running their last saved schedule manually. Some models like the Yardian Pro offer Ethernet as a more stable alternative, and the Hunter PRO-HC has an on-device touchscreen that works independently of the app.
How do smart sprinkler controllers work?
Smart sprinkler controllers replace your traditional irrigation timer and connect to your home Wi-Fi. They pull local weather data including temperature, rainfall, wind speed, and humidity, then automatically adjust watering schedules to match conditions. Advanced models use evapotranspiration calculations to determine exactly how much water your lawn loses each day and replace only that amount.
Final Thoughts on Smart Sprinkler Controllers for Lawns
After testing all 10 controllers across multiple seasons, the Rachio 3 remains my top pick for the best smart sprinkler controllers for lawns. Its Weather Intelligence, Flex Daily scheduling, and clean app experience set the standard that other controllers aim for.
For budget-conscious buyers, the Orbit B-hyve Indoor 8-Zone delivers the core smart features at a fraction of the cost. And for homeowners without an existing in-ground system, the Aiper IrriSense 2 offers a complete all-in-one solution that is hard to beat for convenience.
Whichever controller you choose, the water savings are real. Pick the model that matches your zone count, smart home ecosystem, and budget, and you will wonder how you ever managed irrigation with a dumb timer.
