Short answer
Choose the Rachio 3 if you want the more capable smart controller: Wi-Fi on either band, two sensor inputs and zone-fault alerts on your phone, on a controller that hangs indoors. Choose the Orbit B-hyve 6-zone if you want a dial at the unit as well as the app, need to mount it outside without an extra box and have six zones or fewer. It also costs less.
These are the two smart controllers homeowners compare most when an old sprinkler timer needs replacing: our best overall pick and our best value. Both are on EPA’s list of WaterSense labeled weather-based controllers, both drive standard 24 VAC valves from any brand and a master valve or pump start relay, and both carry a two-year warranty. We score them 8.3 and 8.1 out of 10, too close for either to win outright, so the right one depends on where the controller will hang, who changes the schedule, how many zones you have and your Wi-Fi. We compared the 8-zone Rachio 3 (8ZULW-CP) with the B-hyve 6-zone indoor/outdoor model (57946); both are in our comparison of every sprinkler controller we track.

Choose the Rachio 3 Smart Sprinkler Controller (8-zone) if you want Wi-Fi on either band, two sensor inputs and zone-fault alerts on your phone, and the controller can hang indoors.
Choose the Orbit B-hyve Smart 6-Zone Indoor/Outdoor Controller if you want a full dial at the unit as well as the app, an outdoor-ready cabinet and six zones or fewer, for less money.
Controls at the unit
This is the clearest split. Behind the B-hyve’s cabinet door is a dial with a classic timer’s settings: start times, run times, how often, budget and manual, for four programs with up to four start times each. Budget scales every run time from 10 to 200 percent, and a rain delay pauses watering for 1 to 32 days, so you can set the whole schedule without a phone. The Rachio 3 has buttons to pick a zone on its light bar, run it and stop it: enough while you fix a head, but schedules live in the app. One B-hyve owner we read chose it over a Rachio for exactly this reason.
Wi-Fi and setup
The Rachio 3 joins 2.4 GHz or 5 GHz networks, so it can use whichever band reaches the wall best. The B-hyve pairs with its app over Bluetooth, then joins Wi-Fi on 2.4 GHz only: Orbit’s manual says 5 GHz networks won’t appear in the app, and asks for at least two bars of signal where the timer hangs. Dual-band is no promise of a steady link. Some Rachio owners we read report units dropping off Wi-Fi, one every late spring, and missing waterings; others cured it by reserving a fixed IP address on the router or moving to the 2.4 GHz band. One B-hyve owner reports occasional drops that a reboot clears.
Fault alerts and sensors
Both notice a shorted zone, but the Rachio tells you more. When a valve wire or solenoid shorts, it sends a notification to your phone, logs the zone and pulses red over it on the light bar. The B-hyve shows Fault and flashes the zone number on its display, and stops powering that terminal until the fault is fixed. The Rachio also has two sensor inputs, for normally closed rain, freeze or soil sensors or a wired flow meter; the B-hyve has one pair of rain sensor terminals. Florida and Texas require a rain or moisture shut-off on new automatic systems (Texas also when the controller is replaced), and both controllers accept a wired rain sensor.
Mounting indoors or out
Rachio builds the Rachio 3 for indoor walls. Outside, it has to go in Rachio’s weatherproof enclosure (part 16RACHBX), sold separately; Rachio rates the controller for -13 to 140°F. The B-hyve’s cabinet is weather-resistant to the UL-50 enclosure standard, so it can hang on an outside wall as it comes, out of direct sun and running water, plugged into a 110 V GFCI outlet; Orbit gives its operating range as 32 to 158°F. If the old timer is in a garage, either will do; on an outside wall, the B-hyve saves buying the box.
Safety: both controllers come with a plug-in transformer. Rachio says never to hardwire the Rachio 3 itself, only through its outdoor enclosure with the power off at the breaker, and to ask an electrician if you have any doubt. Orbit advises an electrician for hardwiring the B-hyve and a GFCI outlet when it hangs outside.
Zones and wiring
Count the zone wires on your old timer before you choose. The Rachio 3 we compare has 8 zones, and Rachio sells the same controller with 4, 6, 12 or 16. The B-hyve has 6; Orbit’s 12-station model (57950) shares its manual. The Rachio’s terminals accept 14 to 22 gauge wire. The B-hyve manual asks for 20 gauge on runs under 700 feet and 16 gauge beyond, and allows one valve per station terminal at up to 250 mA, so if your old timer drives two valves from one terminal, plan to split them. Not sure how many zones your yard needs? See how many sprinkler heads per zone, and how many zones you need.
Weather skips and offline running
Call this one a tie. EPA lists both as WaterSense labeled weather-based controllers that take their weather data over the internet, and estimates that swapping a clock timer for a labeled controller can save an average home up to 15,000 gallons a year. If the internet drops, Rachio says the Rachio 3 keeps running its stored schedules, but weather skips stop until it reconnects. The B-hyve keeps its programs in memory, and its dial schedule never needed Wi-Fi. Owners we read like the Rachio’s weather skips once tuned, though its first smart schedules can ask for very long run times; one B-hyve owner found its smart watering ran too little in a hot, dry spell.
Price, add-ons and warranty
The B-hyve costs less; current prices are at the top of this comparison. Neither charges a monthly fee. Rachio includes its weather features and sells two extras, Valve Monitoring and Heat Wave Boost, as optional one-time purchases; Orbit describes the B-hyve app as free. Both warranties run two years. Orbit’s transfers to a later owner, which helps if you sell the house; Rachio’s covers units bought from Rachio or an authorized dealer, not second-hand ones. Both can qualify where your water utility offers a smart-controller rebate, and several Rachio owners we read say one covered much of the cost.
What owners report
These are anecdotes from small samples, not failure rates.
- Rachio 3: we read 48 owners, 33 on Rachio’s own community forum and 15 on Slickdeals. Several report three to seven years or more, indoors and outdoors in the enclosure. Against that, threads from 2023 to 2026 describe units that would not boot after a winter or died around the end of the two-year warranty, and refurbished replacements that also failed. A support forum gathers problems, so it shows what goes wrong, not how often.
- B-hyve 6-zone: we read 27 owners, 14 on Orbit’s store and 13 on Slickdeals. Several report four or five years without trouble; one rental owner had a unit fail within a year and its replacement after seven months. Orbit’s store reviews come from recent buyers, and we left out those marked as earning a discount.
Rain Bird bought Rachio in October 2025. Rachio is now a wholly owned subsidiary and still sells under its own name, so warranty claims for a Rachio 3 still go to Rachio.
What about the B-hyve XR?
The Orbit B-hyve XR is Orbit’s outdoor 8-zone controller (a 16-station version is sold too). It answers two of the 6-zone’s limits: it joins 2.4 or 5 GHz Wi-Fi, and Orbit builds it for walls exposed to the weather. It is on EPA’s WaterSense list too, and on Wi-Fi it can act as the hub for B-hyve hose timers. We rate it lower because we could not read its manual, so its sensor wiring and warranty length are unconfirmed, and we found too few owner reports to judge it. When we last checked, one store sold it for about what the 6-zone costs, so compare the offers on its page.
Which should you choose?
Choose the Rachio 3 if…
- The controller hangs indoors, or you’ll add Rachio’s enclosure outside
- You want the choice of 2.4 or 5 GHz Wi-Fi
- You want zone-fault alerts on your phone, or a second sensor such as a flow meter
- You have seven or eight zones, or need the 12- or 16-zone version
Choose the B-hyve if…
- Someone in the house wants to set schedules with a dial at the unit
- It will hang on an outside wall with a GFCI outlet nearby
- You have six zones or fewer, or will buy the 12-station model
- You want to spend less, with a warranty that passes to the next owner
Neither quite right? The best smart sprinkler controllers ranks all eight we track, including Rain Bird’s ESP-TM2, a dial timer that goes online only with Rain Bird’s LNK2 module, and the expandable ESP-Me3. Or compare every sprinkler controller side by side.
How we compared them
- Read both makers’ manuals, install guides, spec sheets and support pages for controls, Wi-Fi, sensors, mounting, wiring limits and warranty.
- Checked both models on EPA’s WaterSense product list on November 2, 2026.
- Checked prices at Rachio, Orbit, Sprinkler Warehouse and DripWorks, and show the date we checked.
- Read 48 owner posts about the Rachio 3 and 27 about the B-hyve 6-zone for reported problems. The samples are small, and we say so.
What we don’t do: install or bench-test controllers. Everything here comes from the makers’ documents, EPA’s list and what owners report.
Rachio vs B-hyve questions
Do the Rachio 3 and B-hyve qualify for water rebates?
Often, in the US. Both are on EPA’s list of WaterSense labeled controllers: the 8-zone Rachio 3 as 8ZULW-C and the B-hyve as 57946. Rebates come from local water utilities, not from EPA, and each sets its own terms. Search EPA’s WaterSense rebate finder or ask your utility before you buy, and keep the receipt.
Did Rain Bird buying Rachio change anything for buyers?
Not that we can see yet. Rain Bird announced on October 1, 2025 that it had acquired Rachio, which became a wholly owned subsidiary, keeps its co-founder as chief executive and still sells controllers under its own name. The Rachio 3 still carries Rachio’s two-year warranty. We’ll update this page if the app, support or compatibility changes.
Can I buy either one in Canada?
Not easily. We found no Canadian retailer selling the US Rachio 3 (8ZULW-CP), and Rachio’s store prices in US dollars. Orbit’s Canadian store lists the 6-zone as part 91946 rather than 57946 and charges in US dollars, and Orbit doesn’t say the two are identical. WaterSense is a US label, so ask your utility whether any rebate applies.
Will the B-hyve work if my router only broadcasts 5 GHz?
No. Orbit’s manual says the B-hyve 6-zone connects only to 2.4 GHz networks, and 5 GHz networks won’t appear in its app. If your router also broadcasts a 2.4 GHz network, use that one. If it doesn’t, the Rachio 3 and Orbit’s B-hyve XR join either band, and the B-hyve’s dial still runs a full schedule with no Wi-Fi at all.
