Notifications - Rachio Wireless Flow Meter and wired flow meters

What are flow notifications?

If you have a wired flow meter or Rachio Wireless Flow Meter installed with your Rachio controller, you can receive notifications to alert you of potential problems with your system.

Notifications can appear as push notifications, emails, in-app notifications, and events within the History feed.


Some notifications are exclusive to Rachio Wireless Flow Meter and will not appear with wired flow meters. See below for details.   

Why are flow notifications important?

Notifications should be relatively rare, but they are essential for alerting you to expensive or damaging issues related to flow rates or leaks. As a user, you cannot turn off flow notifications, as they are an essential piece of the flow monitoring process and crucial in alerting you if something is wrong. If you find that notifications are too frequent, you may adjust your thresholds to decrease your flow meter’s sensitivity.

What types of flow notifications may I receive?

There are several types of notifications. Some, like a high-flow leak, may require immediate attention.

Types of notifications: 

  • High-flow leak with auto shut-off. This alerts you to a high-flow leak and any zones that have been disabled to protect against the leak.

    High flow leak detected with auto shut off

  • High-flow leak without auto shut-off. This alerts you that a high-flow leak has been detected. If auto-shutoff is disabled, the problem zone will continue to run. 

    High flow leak detected

  • Low flow. This alerts you to any low flow observed outside of your set thresholds. This could deprive your landscape of necessary water or damage your system, so we recommend disabling the zone and attempting to resolve the issue. Check for common causes such as: 

    • Root crush (where tree roots grow around a pipe and squeeze it closed)
    • Obstruction of sprinkler head
    • Low water pressure


  • Inactive Flow / Flow detected when no zones are running. This alerts you to flow detected while your sprinkler system is not currently watering (either scheduled or manual watering). If your system is not active and water is still flowing through it, this could signal a leak. To investigate the cause, check for the following: 
    • Running hose connected to outdoor water
    • Stuck valves
    • Leaks between the flow meter and your valves 


Noticing frequent Inactive Flow alerts? Your system could be slower to depressurize after watering, which can lead to false positives. Go here to learn about false positives and how to adjust your Settle Time. 

  • Battery low (available only for Rachio Wireless Flow Meter). This informs you of low battery in your Wireless Flow Meter before your battery runs out of power. 

  • Flow meter connection lost (available only for Rachio Wireless Flow Meter). This alerts you to any lost connection between your flow meter and the Rachio 3 Smart Sprinkler Controller. 

  • Flow meter reconnected (available only for Rachio Wireless Flow Meter). This informs you when your flow meter reconnects to your Rachio 3 Smart Sprinkler Controller.
