YoLink Water Leak Detector, 1/4 Mile World's Longest Range, Wireless Smart Water Leak Sensor, Alexa, IFTTT, Hub Required
Key item features
- NO WiFi WORRIES! 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 (Not included!). Long range, obstruction penetration, no reliance on WiFi, 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.
- NO WIFI, NO INTERNET, NO POWER? NO PROBLEM! Our patented Control-D2D device-to-device pairing, over our LoRa-based wireless network, allows for devices to be paired to each other, in such a way they will continue to operate, even if WiFi is flaky, the internet goes down, or the AC power goes out!
- START SMART! A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business!
- BATTERIES INCLUDED! Two replaceable AAA batteries, good for over 5 years, are included!

About this item
Product details
YoLink, by YoSmart, a US corporation based in Irvine, California, is a line of wireless smart products for residential and commercial use, utilizing wireless technology initially utilized for industrial and other large-scale applications.
This technology, LoRa, short for Long-Range, is unique in the smart home industry and provides you with benefits that include 2 to 10 year battery life, 1/4 mile extreme long range, superior wall and obstruction penetration, including concrete, masonry and even metal!
YoLink benefits include a more secure automation network due to a centralized and encrypted internet connection, as the devices are not on the internet and they do not rely on WiFi. All communication is encrypted, and controlled by AWS servers, for finance-grade security, backups and redundancies.
Our patented Control-D2D device-to-device pairing allows for offline operation, including functionality even after the loss of WiFi, internet, and AC power, making it perfect for your critical operations, such as water leak detection and automatic shut-off and security.

Peace of mind if the Water Heater leaks !!
I have an old Water heater that I always worry about. This Leak detector gives me peace of mind, as I have already ordered numerous devices from YoLink, so I knew it would be easy to set up and very compatible with Alexa, and even IFTTT to set up alert routines. I was not disappointed - Set it up and tested it with a routine in under 10 minutes !!
