YoLink FlowSmart All-in-One Smart Water Meter & Auto Shutoff for 3/4-Inch Pipes – NSF Certified, LoRa, Real-Time Leak Detection, Hub Included

Overview

YoLink FlowSmart is an NSF-certified, all-in-one smart water meter and motorized shutoff built for potable-water lines. It supports pipe sizes from 1/2 inch to 2 inches, including 3/4 inch, with a compact measurement tube designed to maintain accuracy across common household and light-commercial flows.

What you get in real life

In everyday use, FlowSmart acts as a vigilant partner for water safety and consumption awareness. When it detects unusual usage or a potential leak, it can shut the valve automatically and send timely alerts. This combination of sensing and control can help you act quickly without manual checks.

• NSF CERTIFIED, ALL-IN-ONE: integrated ultrasonic water meter and motorized shutoff valve for potable-water lines; sizes include 1/2, 3/4, 1, 1-3/4, 1-1/2, and 2 inches.
• REAL-TIME LEAK DETECTION + AUTO SHUTOFF: detects leaks and abnormal usage and closes the valve automatically; scheduling and alerts included.

• WORKS EVEN WITHOUT INTERNET: device-to-device rules let critical shutoff actions continue offline for resilience.
• LORA LONG-RANGE RELIABILITY: purpose-built low-power radio provides whole-home coverage where Wi-Fi struggles.
• 10+ YEAR BATTERY DESIGN: long-life power system designed for multi-year operation.

• HUB & CONNECTIVITY: requires YoLink Hub; Ethernet or 2.4 GHz Wi-Fi for flexible installs; works with Alexa, IFTTT, and Home Assistant.
• ABOUT PIPE SIZE & FLOW: sized by nominal pipe size (NPS) for thread compatibility; the ultrasonic measurement tube is intentionally smaller to meet accuracy standards and stabilize readings; designed for typical household and light-commercial service.

For property owners, renters, or facilities managers, the FlowSmart setup can blend seamlessly with existing smart-home routines while offering a lower-touch way to monitor water use and respond to change. The 80+ device ecosystem means you can pair it with other YoLink sensors, hubs, and automations to build a broader safety and efficiency system. While results vary by installation and water use patterns, many users report tighter monitoring, faster responses to anomalies, and a clearer view of consumption over time.
