Rachio vs. Rain Bird vs. Orbit B-hyve: smart sprinkler controllers compared

By Smart-Irrigation.com · Last reviewed October 2026 · Sources linked inline and listed at the end

Rachio, Rain Bird, and Orbit's B-hyve line show up on nearly every Front Range rebate list. This guide compares them using the manufacturers' published specifications, so you can pick the one that fits your system and your utility's rules.

Our method: we compared manufacturer specification pages and utility eligibility lists. We have not hands-on tested these controllers. Prices are list prices shown on the manufacturers' stores when we checked in October 2026 and will change.

The short version

All three brands appear on Aurora Water's list of eligible smart controllers (City of Aurora), and most Front Range rebates require EPA WaterSense certification. That makes the WaterSense status of the exact configuration you buy the single most important detail.

Rachio 3

Rachio's pitch is software. Its product page describes three schedule types: Fixed schedules, where you set specific days and times (Rachio notes this is helpful if you have watering restrictions); Flex schedules, which Rachio updates daily or monthly; and overseeding schedules. Automatic adjustments include Rain Skip and Seasonal Shift. Rachio says the app has no monthly fees, but some features, such as Heat Wave Boost and Valve Monitoring, are listed as "premium" (Rachio).

Rachio says most users can expect to save 20% or more water compared with traditional controllers (Rachio). That is the manufacturer's own claim, not an independent result. It also integrates with a Tempest personal weather station if you want backyard weather data.

Colorado note: Colorado Springs Utilities allows sprinkler watering up to three days a week (Colorado Springs Utilities). If you use a Flex-style schedule on any controller, make sure it can't water on more days than your local rules allow. Fixed schedules make this simple.

Rain Bird ARC8 and ESP-TM2 with LNK2

The ARC8 is Rain Bird's all-in-one smart option. Rain Bird lists eight stations plus a master valve or pump start relay and a rain/freeze sensor input. It has three programs with four start times each, custom, odd/even, and cyclical day options, and a watering delay of up to 14 days. Rain Bird says its self-adjusting technology "reduces water usage up to 30%" by using historical weather averages, yesterday's weather, and tomorrow's forecast for your postal code (Rain Bird).

The ESP-TM2 is a conventional controller in 4-, 6-, 8-, and 12-station models that can be made "smart" by plugging in the LNK2 Wi-Fi module (Rain Bird). Two details matter for rebates and setup:

The ESP-TM2 route makes the most sense if you need more than eight zones but not more than 12, or if you already own a compatible "LNK Ready" Rain Bird controller.

Orbit B-hyve XR

Orbit lists the B-hyve XR as controlling up to 16 zones of 24 VAC sprinkler and drip systems. It has three color displays and a light ring that show status by zone, Bluetooth plus dual-band 2.4/5 GHz Wi-Fi, and four program slots (A–D) with multiple start times for cycle-and-soak. It can power a pump start relay and one valve solenoid at the same time. Orbit says its WaterSense label qualifies it for rebates in many areas (Orbit). Orbit also lists a rain delay feature to skip watering during rain or freeze, and a digital lock-out to prevent tampering at the device.

The on-device display is a practical difference if more than one person in the house needs to check or change watering without opening an app.

How to choose

  1. Count your zones. Open your current controller and count the wired stations. Buy for the number you have, with room to grow if you plan to add drip zones.
  2. Check your Wi-Fi where the controller will hang. Garages and exterior walls are often weak spots. The LNK2 needs 2.4 GHz.
  3. Check the program first. If you are a Colorado Springs Utilities customer, the free controller program may make the decision for you. Elsewhere, see our Front Range rebate table.
  4. Confirm WaterSense for your exact model and configuration on EPA's WaterSense controller pages before you buy. Rebates often require it.
  5. Keep the receipt and take a photo of the installed unit. Aurora and Thornton both require an installation photo for their rebates.

Installation notes

All three are designed to replace a standard 24 VAC controller using your existing valve wires. Rachio says the Rachio 3 installs in 30 minutes or less with no special tools (Rachio). Before you disconnect anything, photograph the existing wiring and label each wire with its zone number. If your system has a master valve or pump, check that the new controller supports it. The Rain Bird ARC8 and the B-hyve XR both list master valve or pump-start support.
