YoLink's water detection system uses LoRa long-range radio technology instead of Wi-Fi — a major advantage in basements, crawlspaces, and other areas where Wi-Fi signals are weak or unreliable. The 4-pack sensor kit includes a YoLink Hub and four leak sensors with a stated range of 1,000+ feet through walls and floors. When any sensor triggers, YoLink sends push notifications within 8 seconds — even without Wi-Fi at the sensor location. The LoRa network is also far more resilient during power outages, since it operates on a separate radio frequency. Each sensor runs on included AAA batteries for up to 5 years, and the app displays historical alerts and battery status. YoLink integrates with SmartThings, Home Assistant, IFTTT, and Amazon Alexa. The go-to system for basements, detached garages, and vacation properties.
