The Rachio 3 is the default recommendation in smart irrigation, and the app is why: PCMag scored it 4.5 out of 5, with its reviewer calling it the best designed and easiest to use of the controllers he tested. Weather Intelligence Plus handles rain, wind and freeze skips with no subscription, it ties into Alexa, Google Assistant, IFTTT and SmartThings, and schedules keep running locally when Wi-Fi drops. CNET's take on the same hardware was more measured at 7.5 out of 10. The catches are practical: it needs the supplied AC adapter, it mounts indoors unless you buy the weatherproof housing, and it wants reliable Wi-Fi where the valve wiring is.

Strengths
  • — Automatically adjusts watering schedules based on local weather conditions
  • — Easy installation taking 30 minutes or less with no special tools required
  • — Works with Amazon Alexa, Google Home, and Siri Shortcuts for voice control
Watch-outs
  • — Caps out at 16 zones, so large or commercial properties need a different controller

Unrated2 sources$90.13as of Sep 25

The Rain Bird ARC6 is an indoor smart WiFi irrigation controller that pairs intuitive local controls with a more capable mobile app. Reviewers noted it adjusts watering schedules automatically from weather data, which can cut water use by as much as 30%. It handles up to six stations and accepts a rain sensor, but it has to be installed indoors and needs 120V power. Residential users who want automated irrigation control with smart home integration are the natural buyers.

Strengths
  • — Accommodates up to six stations plus master valve/pump start relay and rain/rain freeze sensor
  • — Self-adjusting technology reduces water usage up to 30% based on weather forecasts
  • — Meets EPA WaterSense criteria and is independently certified by ICC-ES for efficiency
Watch-outs
  • — Limited to indoor mounting only

How they stack up

Rachio WiFi Smart Sprinkler Controller (8-Zone Irrigation Remote Control)

The Rachio WiFi Smart Sprinkler Controller's app carries a 4.9 App Store rating, where the app for the Orbit B-hyve Indoor Smart Sprinkler Controller is described as finicky and confusing.

Rain Bird ARC6 Smart WiFi Sprinkler Timer

The Rain Bird ARC6 Smart WiFi Sprinkler Timer runs up to six stations, the same count as the Netro Smart Sprinkler Controller (6-Zone) and two fewer than the eight-zone Rachio WiFi Smart Sprinkler Controller, which costs more.
