YoLink SpeakerHub Leak Detection Starter Kit — Water Leak Sensor 4 3-Pack, 105dB Alarm, LoRa up to 1/4 Mile, SMS/Text, Email & Push Notifications, Freeze Warning, w/Alexa, IFTTT

All-in-one leak protection: The YoLink SpeakerHub Leak Detection Starter Kit includes one hub and three Water Leak Sensor 4 units to monitor and alert you to water issues. Placement is simple — put a sensor near or under appliances and areas at risk of leaks, such as toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, and sump pumps. It’s also useful for other likely leak points. Long-range coverage: Using LoRa technology, this system can reach up to 1/4 mile in open-air, making it reliable in hard-to-reach spots like basements, outdoor areas, sheds, and remote outbuildings where Wi-Fi may be weak. Loud local alarm: Each Water Leak Sensor 4 features a powerful 105dB audio alarm so you can hear alerts immediately and respond to potential flooding before serious damage occurs. Durable, weather-resistant build: The sensors carry an IP66 waterproof rating to withstand wet conditions. Freeze protection: A built-in low temperature sensor provides freeze warnings, helping you avoid burst pipes and cold-weather damage. Smart home expansion: The YoLink Hub supports over 300 devices across YoLink’s product line — security, environmental sensors, power and lighting modules, smart locks, and upcoming cameras — allowing future system growth. Setup and notifications: To use the kit you need an Android or Apple smartphone and a stable 2.4GHz WiFi connection. The app is free and includes 5 complimentary texts per device; this kit provides 20 free SMS per month. Additional SMS plans are available for $2 or $5 per month. Power that lasts: The package includes eight replaceable AAA batteries that provide power for over 5 years, giving long-term, low-maintenance protection.
