Flume is a smart home water monitor that straps directly onto a home’s existing water meter — no pipe cutting, no plumber. It reads the meter’s magnetic field to measure usage down to one-hundredth of a gallon, and it uses machine learning to detect leaks and abnormal water use, alerting you right away.
The battery-powered Flume sensor and its Wi-Fi Bridge send data to the Flume app, where homeowners see real-time and historical consumption, set customized budgets, and receive leak notifications whether they are home or away. Flume reports that 70% of users receive a leak notification within their first 30 days, and that customers reduce their water use — and their bills — by about 15% on average. The Detail+ feature goes further, breaking usage down by category: toilets, showers, dishwashers, water softeners, sprinkler systems, and more. A newer Flume 2X model adds a reinforced weather-resistant design, upgraded Wi-Fi, and longer battery life.
Flume 2 is a paid hardware product priced at $249 from Flume’s store. Many local water utilities partner with Flume to offer discounts and rebates, which can lower the cost significantly depending on where you live.
Homeowners who want leak alerts and detailed water-use insight with a ten-minute DIY installation — and no changes to their plumbing at all.
Flume partners with water providers across the country, so many households can check whether they qualify for a discount or rebate on the device before buying.
