Rachio Smart Sprinkler Controllers are all about saving you water. We create customized watering schedules for your irrigation system that reduce water use and gives you control from anywhere. The NEW Rachio 3 Smart Sprinkler Controller expands on our best-selling Rachio Generation 2 Smart Sprinkler Controller with a sleek new look, game-changing technology and upgraded Weather Intelligence Plus.

Can I control my watering when I’m not on my Wi-Fi network?
Yes, you can! Once your Rachio controller is connected to your home’s Wi-Fi network, you can control it from practically anywhere as long as you’re connected to the internet (through your data plan, another Wi-Fi network, etc).

Battery Backup
The controller does have a battery backup, but it’s not used to maintain a schedule; instead, it’s used to maintain an internal clock so that when the controller comes back online, it can resume running your schedules correctly, before syncing with the Rachio cloud.

Keeping track of waterings while offline
Even when your controller is offline, it will still continue recording watering events and keeping track of which zones are watered when (and with how much water). Each watering event will be cached on the controller and then combined with your watering history once the controller comes back online.
