  • Why Worry About WiFi? YoLink devices communicate by LoRa, an industrial-grade protocol that provides up to ¼ mile open air range. Devices do NOT connect to your network or even to the internet; they communicate with the Hub. Strong signal level, obstruction penetration, no (WiFi) holes in your internet security, and fully-encrypted communications provide more than most ask for from their smart home system!
  • ⏱ Set it & Forget it! Installs in seconds! The YoLink wireless Water Sensor could not be easier to install; just place near or under the equipment you wish to monitor. Suggested uses are near or under, toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, in or near sump pumps, and by any other location subject to water leaks and flooding.
  • Extreme Long Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property. Low-power operation squeezes the most out of the batteries, which can last from 2 to 10 years!
  • Know Now! Choose from activation of 3 siren models, the (audio) SpeakerHub, app notifications, emails, text messages and automated calls*, as well as central station monitoring, for your most-critical applications. This sensor is water-tight and does not have an integral sounder. Consider our Water Leak Sensor 2 and/or one of our smart sirens and/or the new SpeakerHub.
  • ⚠️ Requirements – Android or Apple smartphone, YoLink Hub or YoLink SpeakerHub is REQUIRED! (please search B09FSS95G9 for SpeakerHub, our new audio SpeakerHub or B07TQLKQLJ for the original Hub) and wired ethernet port (original Hub) or stable WiFi connection (SpeakerHub or original Hub) *Optional central station monitoring, and optional add-on SMS and automated calls subscriptions are available. App is always free, with 5 free texts per device, plus 5, per month.
