What if my controller goes offline?

Rest Assured

Most connectivity issues you might see are normal behavior; the Rachio controller's Wi-Fi features hinge on the reliability of:

  1. Your internet service provider (ISP)
  2. Your in-home router and/or access point.

However, unless the device goes offline for an extended period of time, you won't experience any loss in functionality your controller. In situations of more lengthy disconnects, we send out email and push notifications to letting you know your controller has been offline for 24 hours and needs to be power cycled (unplugged and plugged back in).

On-Board Schedule Memory

If for some reason the Rachio doesn't reconnect to the Wi-Fi, the controller will continue to run the last schedule it saved until it can reconnect. The controller utilizes EEPROM (persistent memory), so the last saved schedule(s) are stored on the controller itself.

So please rest assured - if your Rachio controller loses connectivity with your Wi-Fi, it will always continue to water using the last saved schedule. Any updates/changes made to these watering schedules will automatically upload to the controller the next time it reconnects with the Rachio cloud (internet).

Note

If you are running Flex schedules, the Rachio controller will not run the last saved schedule, as they are dynamic. Instead, we will create a two week schedule based on the forecast for the upcoming two weeks. After the controller has been offline for that two week period, it will then revert to a Rachio-supplied default watering schedule until the controller gets back online. Then, we will send the controller a new schedule based off of your Flex Daily schedule selections.

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.

Total Blackout?

Should you lose power to your home, the system will not run because there is no way to power the solenoid valves without electricity (24VAC). When power is restored to your home, the Rachio controller will automatically reconnect to your Wi-Fi network.
