Lower your water bill

Surprise bills are a thing of the past. Buoy shows your use water in real time so you can control your water budget, and stop paying for water you're losing to slow leaks.

Prevent costly damage

A leaking pipe can wreak havoc on your home. Buoy alerts you when there's a leak and lets you shut off your water remotely, preventing costly damage and water waste.


Keep your water lifestyle

Use water where it matters most to you. Buoy's data means you can keep your lawn or pool and be a responsible water consumer without big sacrifices to your lifestyle.

The toilet in my guest bathroom has always run. It was so quiet that it seemed like it was very little water. After I had Buoy installed, I was able to quantify that toilet running. It ended up being about 150 gallons/day and doubled my regular daily water usage. I realized the money lost was the equivalent of buying three new toilets a year.

What is Buoy?

Buoy is a smart home water device that attaches to your water line and sends real-time data to an app that categorizes your water use, alerts you to leaks, and lets you shut off water remotely.

It's as easy as 1-2-3


Install and connect

Once it's attached to your water line, Buoy's sensors detect even the smallest water use. When you connect Buoy to WiFi, Buoy will send your water use data to the app.


Download and learn

Get the Buoy app, then dive into your water — or don't. Buoy automatically categorizes your water usage, so you can see the big picture or dig into the details.


Shut off and relax

Buoy sends you an alert when it detects a leak; if you're worried about damage, you can shut off your water remotely via the app, giving you control and peace of mind.

See your water in action.

Buoy mobile app


After a licensed plumber installs your Buoy next to your home's water shutoff valve, you use the Buoy app to connect your Buoy device to your home network.

Buoy gets to work immediately, flexing its machine-learning muscle to analyze your water data. From the moment you're connected, you can see your household water use and, in an emergency, shut off your water from a button in the app.
