About this item

  • Track and view your water use daily and monthly to get ahead of your water costs, and see how your home compares to others. Over time, Phyn learns your system and communicates your water usage down to each fixture.
  • Discreet but powerful, Phyn monitors your entire home from one under-the-sink location. Easily install under any sink with hot/cold water lines and a power outlet.
  • Phyn measures microscopic water pressure changes in high definition — 240 times every second — to recognize the unique voice of each fixture in your home. So when you run a faucet, Phyn knows it’s a faucet. And if that faucet leaks, Phyn lets you know.
