• REAL-TIME LEAK DETECTION + AUTO SHUTOFF – Detects leaks/abnormal use and closes the valve automatically; scheduling and alerts included.
• WORKS EVEN WITHOUT INTERNET – Control-D2D device-to-device rules let critical shutoff actions continue offline for resilience.
• LORA LONG-RANGE RELIABILITY – Purpose-built low-power radio for whole-home/building 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; the assembly is engineered for typical household/light-commercial service flows.
