About this item

• 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.
• KNOW NOW! You have many options for being notified of device activity! Receive a text, receive an email, receive a phone push notification (including Apple phone "Critical Alert" severe weather/Amber alert type notifications that will activate your phone even if in silent mode. Android phones offer similar functionality, depending on phone manufacturer). SMS messages are limited to the total of 5 times each device plus 5. A hub and three sensors provides you with 25 free SMS per month.
• 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.
• THAT WAS SIMPLE! Effortless DIY setup that doesn't need a plumber (you've got this!), takes only a few minutes to install. Just PLUG IT IN, the Plug & Play Hub connects straight to your router, and once you SET IT UP, you can FORGET ABOUT IT with the water leak sensors.
• 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.
