Introduction
The YoLink FlowSmart All‑in‑One Smart Water Meter & Automatic Shutoff is a comprehensive smart plumbing safety system designed to protect your home from water damage. It combines real‑time leak detection, ultrasonic water flow monitoring, and automatic shut‑off valve control in a single device that connects to your home network via a hub. This system not only alerts you to unusual water use immediately but also can stop the water flow automatically to prevent costly floods or pipe damage — even if the internet is down.
Product Overview
📊 Smart Water Monitoring with FlowSmart
FlowSmart integrates a water meter and motorized shutoff valve into one unit designed for use on typical home plumbing lines (e.g., ¾″, 1″, or other sizes). It continuously tracks water flow and detects abnormal usage patterns that suggest leaks or pipe breaks, providing real‑time alerts through the YoLink app.
🧠 NSF Certification for Safe Water
The unit is NSF certified for potable, drinking water applications, meaning it meets strict health and safety standards for drinking water systems. This certification indicates it’s safe to use on main water lines that supply your home’s water.
🚿 Automatic Shut‑Off Valve
If a leak or abnormal flow is detected, FlowSmart can automatically close the water supply using its built‑in valve — reducing the risk of major flooding damage. A manual override is also available if you want direct control.
Key Features & Benefits
📲 Long‑Range Connectivity with YoLink LoRa
Using LoRa long‑range wireless technology, FlowSmart can communicate reliably over distances up to ¼ mile in open air — much farther than typical Wi‑Fi or Zigbee systems. This makes it suitable for larger homes, properties with outbuildings, or difficult‑to‑reach areas where Wi‑Fi might be weak.
⚠️ Real‑Time Leak Detection
The ultrasonic meter detects even subtle anomalies in water flow and instantly sends alerts to the YoLink app on your phone. This helps catch leaks early — at the first sign of trouble — rather than waiting until you notice puddles or damage.
🔋 10‑Year Battery Life & Offline Operation
FlowSmart uses low‑power wireless technology that can operate for years on battery power — many models advertise up to 10 years without battery replacement. It also supports device‑to‑device (D2D) automation, meaning critical shutoff actions can occur even without internet or power.
🛠️ Smart Home Ecosystem Compatibility
FlowSmart is part of the YoLink ecosystem, which includes 80+ compatible devices (leak sensors, thermostats, security sensors, etc.). You can integrate it with smart home services such as Alexa, IFTTT, and Home Assistant to expand automation possibilities.
Performance & Daily Use
In everyday use, FlowSmart helps ensure you know what’s happening with your home’s water system in real time. By providing meter readings, alerts, and automatic control, it keeps you ahead of leaks and bursts — which can otherwise cause significant damage or high water bills. Its long‑range connectivity and offline operation mean it stays functional even in basements, garages, or areas where Wi‑Fi fails.
