Best smart sprinkler controller

Whether you’re motivated by water conservation, saving money, a drive to render every aspect of your home smart, or all the above, a smart irrigation controller will scratch that itch.

Rob Schultz

Watering the lawn and garden is a thankless chore, and it tends to be especially wasteful if done with a hose in one hand and a beer in the other. Irrigation systems have made home watering simpler and more efficient, and while the bulk of any sprinkler system revolves around plastic pipes and a set of motorized valves attached to the water supply, the brains of the operation has always been in the controller.

For decades, sprinkler controllers have hardly been elegant devices. They typically consist of a rotary dial, a handful of switches, and perhaps a crude monochrome LCD. This is rapidly changing, as smart sprinkler controllers enter the market. These have come from two angles: Startups looking to disrupt the market with brand-new devices, and old-guard irrigation companies that have upgraded their gear with smart innards. Both approaches to date have shown some merit. Here are our takes on the best gear on the market today.

Best smart sprinkler controller: Rachio Smart Sprinkler Controller (Generation 2)

It’s really no contest in this market: Rachio’s second-generation controller has the most features and is the easiest to use—and it looks good, too.

There’s literally nothing to the hardware itself. It features no external controls at all; everything is setup via the streamlined and intuitive mobile app. Sure, its “smart” watering suggestions are a bit soggy (as are most), but the in-depth logging, right down to the amount of water used, and weather intelligence features, which dial back watering when it’s rainy out, are second to none. An 8-zone and a 16-zone model are available, as is a separate outdoor enclosure if you need it. But the deal-clincher is Rachio’s extensive integration features, which allow it to work with IFTTT plus Nest, Alexa, Wink, Control4, and Nexia devices—far more than any other smart sprinkler on the market.

Runner-up : Orbit B-hyve WiFi Sprinkler System Controller

Unlike Rachio, Orbit has been in this business for more than 40 years, and the B-hyve marks its big entry to the smart sprinkler world.

The device is a monster, ready for outdoor use (or for bludgeoning an intruder to death, should it come down to it) and featuring support for either 6 or 12 zones, depending on the model. Its smart watering recommendations are OK, but making changes is relatively simple through the capable app if you want to tweak them. If you need onboard controls, the B-hyve is fully loaded, so you can tweak your programs or run manual watering sessions without using the app—though there’s quite a learning curve to master said controls. Best of all: Orbit’s B-hyve is incredibly affordable, with the six-zone model available for just $99.

What to look for when shopping for a smart sprinkler controller

Do you have a sprinkler system already? While there are a few smart irrigation controllers that will work with garden hoses or other off-the-rack equipment, most are designed to work with true irrigation controllers that connect to their own water supply and which feature motorized valves and dedicated tubing to control the flow of water. Installing a real sprinkler system can be a big task that requires professional help—particularly if you have a large yard or garden—but upgrading to a smart controller from a “dumb” one isn’t difficult. Consult with a landscaping expert first if you are installing a sprinkler system from scratch, in order to plan out your zones in advance.

On-device controls: Probably the biggest single decision you need to make with a controller is whether you want a device that includes onboard controls, i.e., buttons and a readout directly on the controller that allow you to use it without an app. This can be handy if you have multiple people using the system or, especially, want to give a gardener access to the controller without having to set him or her up on the app. Systems without on-device controls generally lack any kind of display whatsoever except for a status light indicating whether it’s working, so remember you’ll need the app on your smartphone or tablet to do anything with it.

Indoor/outdoor mounting: Are you mounting the unit inside or outside? If outside, you’ll need a weatherproof enclosure for the system. Some vendors sell separate indoor and outdoor versions of their controllers. Others sell an outdoor enclosure as a separate add-on.

The Blossom 7 can control up to seven sprinkler zones independently.

Number of zones: In irrigation parlance, a zone is an area controlled by a valve and its connected irrigation tubing. If you have four valves, you have four zones. Your controller needs to have enough capacity to support all the zones in your system. Eight zones is common, but units supporting as few as six zones and as many as 16 zones are currently on the market.

Scheduling flexibility: How often do you want to water? Every day? Every other day? On specific days of the week? Not every controller can handle complex schedules, so look closely at your options before buying. A few controllers can even import legal watering restrictions information for your zip code, to ensure you aren’t watering on prohibited days.

Notifications: It’s helpful to be notified when your watering system is running, but different products deal with the mechanics differently. Push notifications are common, but many only notify you when the watering has completed, not when it starts (which is arguably more useful). Other forms of notification (email, text) aren’t common, so consider a unit that supports IFTTT if you want to get fancy with notifications.

“Smart” scheduling: Once of the great promises of smart watering systems is that they can take into account your local weather and environment to optimize your water delivery. We’ve found that these don’t work all that well (they have a tendency to over-water), though options that skip watering when it rains can be a bonus feature. Otherwise, there’s not too much of a need to put weight on so-called “smart” scheduling features.

Smart-home hub support: Want to tie your sprinkler system into your smart-home hub? Sounds great, but the reality is that most smart sprinklers exist as islands today: Only a few connect to anything at all, though Amazon’s Alexa has a modicum of support. Expect this to change as these products mature.
