About this item

• LONGEST RANGE, BY FAR: wireless 1/4 mile open-air range, and superior obstruction penetration (even through metal!), and extreme long battery life, thanks to LoRa (Long-Range) and low-power cutting-edge technology.
• THAT WAS EASY! Simple, no-plumber-required, DIY installation (you can do it!), installs in minutes. PLUG, PLUG & PLAY Hub installation (plug it directly into your router), and SET IT & FORGET IT water leak sensors.
• DON'T JUST DETECT, PROTECT: Everything you need to start your smart water leak protection system! State-of-the-art smart water leak sensors and automatic water shut-off, even if the internet is down and the power is out, thanks to our unique Control-D2D device-to-device pairing.
• GET INFORMED! There are multiple ways to receive notifications about device activity. Get a text, get an email, get a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will bypass silent mode. Android phones may have similar features, depending on the manufacturer). SMS messages are capped at 5 per device, with a total limit of 5 devices. A hub and three sensors come with 25 free SMS per month.
• DON'T TRY THIS WITH WiFi! YoLink devices do not use your WiFi, while typical smart devices do and can bog down your network and can even present a security risk. Our 923.3 MHz Chirp Spread Spectrum technology allows you to place sensors on other floors and even in other buildings, through concrete and even metal, where WiFi can't reach or is spotty.
