## Description

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.

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.

## Customer Reviews

### ⭐⭐⭐⭐ It is US wifi not Uk
*by M***L on 9 July 2024*

Works well once reset to Europe wifi but it would not connect with their European/UK hub without a fair amount of resetting and liaison with tech support.I was expecting this so was not a problem for me.

### ⭐ Does not work in UK, description not clear
*by J***. on 4 February 2025*

The hub and temperature sensors work well and are connected immediately. I purchased the 3-pack water leak sensors but did not realise the difference between UC and EC on the labels. UC does not work in the UK; you need to buy EC. I contacted tech support, but after an initial hello, I have been ghosted!
