YoLink Water Leak Sensor 1 Kit: 6-Pack + Hub

Highlights from the listing

• What’s Included: This package includes 1 YoLink Hub and 6 Sensors—7 items total. The “Number of Items: 7 Pack” refers to the 7 individual products in the package, not 7 sensors.
• Catch leaks at home or away: Includes 6 Water Leak Sensor 1 units and 1 YoLink Hub. Get app, email and SMS alerts through a powered, online YoLink hub (SMS limits apply). Name each sensor by room so you know where to check. Sensors are silent, with no built-in siren.
• LoRa coverage up to 2034 feet: Built on Semtech LoRa technology, sensors communicate with the hub using a low-power radio link. Monitor basements, laundry rooms and other indoor leak-prone areas across large properties. Up to 2034 feet (620 meters) in open air; walls, metal and placement affect actual range.
• Add automatic shutoff, even during outages: Control-D2D lets a sensor directly trigger multiple compatible YoLink shutoff devices, including EVO, Bulldog, motorized valves and FlowSmart ultrasonic meter/shutoff systems. Once paired, local control works without internet or hub power while sensors and shutoff devices remain powered and in range. Choose battery-powered shutoff options for operation during AC outages. Shutoff hardware sold separately.
• Up to 5 years of battery life: Each sensor includes 2 installed, replaceable AAA batteries for fewer battery changes under sinks and behind appliances. Low-power LoRa helps reduce maintenance. Battery life varies with usage, activity and temperature; check battery status in the app.
• Plug, scan and place: Connect the included hub by Ethernet or 2.4 GHz Wi-Fi. Scan device QR codes in the YoLink app and place sensors near sinks, water heaters or washing machines. Top and bottom probes detect drips and pooling water. IP68-rated sensor housing; indoor use only and avoid continuous submersion. No sensor wiring or individual Wi-Fi pairing required.
