Bring smart plumbing to your home with the Flo Smart Water Monitor and Shutoff. The Smart Water Monitor and Shutoff is a smart home water security system that provides 24/7 protection by monitoring for water leaks—some as small as one drop of water per minute—and other vulnerabilities.

Designed by plumbing and tech industry professionals, Flo Smart Water Monitor and Shutoff is installed on the main water supply line of the home. You can see live water use through the Moen Smart Water Network App, including water flow rates, pressure, and even temperature. If the Smart Water Shutoff detects an issue (e.g. high pressure, freezing water, or a small leak), a water sensor alarm will alert you through the app to assess the issue before it causes costly damage. If there is a catastrophic failure, like a burst pipe, you will be alerted in the app allowing you to shut the water off remotely—no matter where you are. If you fail to respond to the alert or are on vacation, the device can be set to automatically shut off water to help limit damage and loss.

The smart water app notifies you of abnormalities to remotely turn off the water from the Moen Smart Water Network App, or the device can be set to automatically close the valve to help prevent catastrophic damage. In addition to leaks, the device will notify you if it senses a fixture has been left on or if temperatures have dipped too low and pipes are at risk of freezing. The app is free, with no fees or subscriptions required. Should the Wi-Fi connection be lost, the device will still protect the home as it stores the latest learnings locally, allowing it to continue safeguarding the home until a Wi-Fi connection has been restored.

Everything needed for installation is included in the box. Professional installation is recommended and takes just a few hours when the home meets installation requirements.

The colors of the physical product may vary.

Customers find the water monitor easy to install with software that's simple to use, and appreciate its ability to monitor water usage and shut off water remotely. However, the device's functionality receives mixed reviews, with some saying it works well while others report it being useless. Moreover, the leak detection feature and overall quality are mixed, with some reporting defects within a week of use. Additionally, the app quality and value for money are also mixed, with some considering it worth the cost while others find it expensive.
