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.
