What is Water Use Plus?

Last updated on 30 Jan, 2026

Water Use Plus is an enhanced water-usage feature that gives you deeper visibility into how water is being used throughout your home. It provides multiple ways to view and understand your consumption, helping you identify trends, spot inefficiencies, and make more informed decisions.

With Water Use Plus, you can see:

  • Monthly usage heat map:
    A visual, at-a-glance view of daily water usage. The darker the circle for a given day, the more water was used.

  • Daily fixture breakdown:
    A breakdown of how much water each fixture type (toilets, showers, irrigation, etc.) used on a given day.

  • Water log:
    A detailed log of individual water activities that can be filtered by:

    • Fixture type

    • Time of day

    • Amount of water used


Is Water Use Plus a paid feature?

No. Water Use Plus is provided at no additional cost to Phyn users.


Can I still view the original water-use charts?

Yes. The existing monthly, daily, and hourly water-use charts are still available in the app under the Water Use tab.


Why is Water Use Plus labeled “Beta”?

During the Beta period, Phyn is continuing to improve how accurately water activity is categorized by fixture type.

Phyn’s AI learns from:

  • Pressure and flow patterns

  • Real-world usage data

  • User feedback submitted through the app

At launch, some fixtures (such as toilets, showers, and sinks) may be identified more accurately than others. Over time, and as more feedback is collected, categorization accuracy will continue to improve across all fixture types.

Note: Improvements may not be immediately visible. As models are built and refined, accuracy will increase gradually.


Why are washing machines and dishwashers harder to detect?

Washing machines and dishwashers vary widely by:

  • Manufacturer

  • Model

  • Wash cycle behavior

Because of this real-world variation, your specific appliance may not be recognized accurately at first. As you continue to use these appliances, Phyn learns their unique patterns and improves detection over time.


How can I improve fixture categorization accuracy?

You can help Phyn learn by correcting labels in the Water Log:

  1. Open the Water Log in the app

  2. Select a water activity

  3. Update the fixture label if it’s incorrect

  • Labels corrected by you are marked with a person icon

  • System-generated labels are marked with the Phyn logo


When will I see improvements from my feedback?

You may not see immediate changes. Initial improvements typically become noticeable within a few weeks, and accuracy will continue to improve over time as Phyn’s AI learns from ongoing usage and feedback.


What does “Uncategorized” water usage mean?

Water activity may be labeled Uncategorized when:

  • The system cannot yet identify the fixture

  • The water use is still in progress

  • The device was temporarily offline

  • The activity is related to a leak alert

Once water use stops, Phyn will usually apply a fixture label within a few minutes.


Why does “N/A” appear for the number of events?

For dates prior to the launch of Water Use Plus, the app can display total water usage but cannot show:

  • The number of events

  • A fixture-level breakdown

This information is only available for data collected after Water Use Plus was introduced.
