Let customers speak for us
from 1599 reviewsWe looked for an inexpensive and accurate way to include school bells (e.g. for recess and lunch), and to provide other emergency messages to each classroom in our small private school. The hub was a critical piece in this application, along with the ability to play back personalized audio files (like an old school bell).
In addition, we added aYolink Outdoor Alarm Controller connected to LED strobes and Yolink Mini On/Off Fobs for a silent alarm in each class . Each teacher has a fob we use as a panic button, that we've set to turn on strobes in every class should there be a threat in or near the building giving our teachers and students an early warning system.

I've had several water leak detectors and also some other 2.5G items that took a lot of time to pair and get working. The YoLink Hub got my 5 leak detectors running in less than 10 mins! I'd definitely recommend if you're looking for an effortless install.

Have used Yo-link door sensors for years. They work perfectly and the batteries are still original!
Great product and will not disappoint.

Delivered on time, water sensor works fine.

Works well relatively easy to install. Since building in 1998 I have had three water leak events, Yolink water leak detector saved a Attic hvac air handler possible over flow this year.

YoLink is my go-to for whole house automation.
I currently use Home Assistant (HA) to control irrigation, wastewater, indoor and outdoor lighting, and solar. YoLink products seamlessly integrate with HA and make things easier for me than other vendors.

When researching this purchase I did find lower cost options but then I thought, If I am on vacation in another state or even half an hour away at work and I get a flow alert do I really want to count on a low cost option? Getting the EVO valve and controller I was impressed by the weight alone. It is a high quality piece of equipment with stainless steel parts. When it turns my valve there are no weird noises or crunching of gears as are mentioned in reviews of lower priced items. Those lower priced options run off WIFI which isn't optimized for where most people have their water valves. Setting up the network and installing the valve was easy.
Save yourself money and heartache and get this item instead of it's competitors. When you need it you will be glad you did.

Bought more sensors for every leak point in the house (16). I feel very secured and safe from flooding.

My issue was handled quickly and efficiently. Exactly what I want when I chat with support.
