The Rachio 3 Smart Sprinkler Controller is the best smart sprinkler controller you can buy for your in-ground irrigation system.
The Rachio 3 WiFi sprinkler controller offers the most features while still being easy enough for anyone to use.
The Rachio app has a busy interface, but it's easy to navigate.
The world's best smart sprinkler controller gets even better, with new features, better wireless connectivity, and smarter water management.
When powered up, the unit emits a high-pitched squeal that I can hear from a few feet away.
I found Rachio's recommended watering schedule to be a bit light, but better than most.
