About this item

• AVOID USING WiFi FOR THIS! Unlike conventional smart devices that rely on your WiFi and can overload your network and potentially pose security threats, YoLink devices operate independently. Our advanced 923.3 MHz Chirp Spread Spectrum technology enables reliable placement of sensors across different levels and even in separate buildings, penetrating through concrete and metal where WiFi signals may be weak or unavailable.
• 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.
• 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.
