Will your schedules still run if your Rachio goes offline? Good news, we have all the answers below! ### Related Articles 1.

However, unless the device goes offline for an extended period of time,  **you won't experience any loss in functionality of your controller if you have a saved schedule**. In situations of more lengthy disconnects, we send out emails and push notifications to let you know your controller has been offline for 24 hours and needs to be power cycled (unplugged and plugged back in). # Schedule Memory If your Rachio device loses its Wi-Fi connection, it will continue to run based on the schedules stored on the controller's internal memory. However, during this time, weather-based features (such as Weather Skips) will not function, since the controller cannot access forecast data without an active wifi connection. ## Sprinkler controllers * **Fixed Schedules:** The controller will continue running the last saved schedule indefinitely, as long as it remains powered on and has not been factory reset.  * **Flex Daily and Flex Monthly 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 those two weeks, it will revert to a Rachio-supplied default watering ## Smart Hose Timer * **Fixed Schedule:** You can have up to 400 individual run events saved directly on the Timer Valve. This means that up to 400 runs will continue to water if the WiFi connection is interrupted. If you have a schedule that runs once a day, the Valve will continue to run for 400 days without internet. #### Note A factory reset clears the controller’s internal memory, including the locally stored schedule data that allows it to run programs offline. As a result, schedules will not run again until the controller reconnects to Wi-Fi and syncs with the cloud. Once the connection is restored, all schedules and settings saved in the app will automatically be re-downloaded to the controller. # Track Offline History Even when your controller is offline, it will still continue recording watering events and keeping track of which zones are watered when and how long it watered. Each watering event will be cached on the controller and then combined with your watering history once the controller comes back online. #### Note If your controller comes back online after an extended period of time, the water usage displayed in your history may be much higher than expected. No need to be alarmed! This is because the controller aggregates all of the cached watering events and reports them at one time; your controller is still watering normally.

As a result, scheduled runs will resume at their appropriate times once power is restored to the device, even if the controller has not yet reconnected to your Wi-Fi. # Do you still need help?
