Flo has to balance protecting against water damage and irritating homeowners by turning off the water while someone is having a long shower. It does learn about 'normal' water flows over time, but 'normal' may still be 20-30 gallons.
Flo
The Flo monitor communicates constantly with the Flo cloud servers so that water flows are tracked and categorised. When a Flo leak detector is triggered, the Flo cloud will generate an alert that triggers the Flo to shut off the water immediately. Similarly, unexpected high water usage will trigger a warning that the water will be shut off in five minutes.
After a flood in the garage due to a burst hose fitting, I installed a Flo by Moen Smart Water Monitor and Shutoff in 2020 to protect against pipe bursts and help monitor water usage.
