YoLink Smart Home Leak Detection Starter Kit — Hub + 3× Water Leak Sensor 4 (105dB Alarm, IP66, Freeze Warning, LoRa up to 1/4 Mile) — SMS/Text, Email & Push, Alexa & IFTTT

What's included: One YoLink Hub plus three Water Leak Sensor 4 units — a complete starter pack for water leak and freeze protection. The hub plugs into Ethernet or connects over 2.4GHz WiFi for a quick plug-and-play setup to get you monitoring in minutes. Placement and use: The compact wireless sensors are designed to sit near or beneath equipment prone to leaks — toilets, water heaters, dishwashers, washing machines, sinks, sump pumps, fish tanks, sheds, and other vulnerable spots. Long-range connectivity: Using LoRa radio, the system delivers industry-leading reception up to 1/4 mile open-air, making it ideal for basements, outbuildings, remote areas, and other locations where WiFi is weak. Audible and environmental alerts: Each Water Leak Sensor 4 includes a powerful 105dB audio alarm to draw immediate attention to leaks. They also feature a low-temperature sensor that issues freeze warnings to help prevent frozen pipes. Durability: Built to endure tough conditions, the sensors carry an IP66 waterproof rating. Smart home integration and scale: The YoLink Hub supports over 300 devices and works with the full YoLink ecosystem — security and environmental monitors, power and lighting products, smart locks, and upcoming cameras. It also integrates with Alexa and IFTTT. Notifications & app: Receive notifications via SMS/text, email, and push messages. The free YoLink app supports Android and Apple devices. The service includes 5 complimentary texts per device and this kit provides a total of 20 free SMS per month; additional SMS plans are offered at $2 or $5 per month. Power: The package includes eight replaceable AAA batteries, designed to provide more than 5 years of operation for long-term protection.
