Let customers speak for us
from 1611 reviewsI use the Local Hub with Home Assistant, and it works great for both local and cloud integration at the same time. Setup was easy, the range is excellent, and local control is fast and reliable. This is a solid step forward for LoRaWAN tech, and YoLink needs to make more local hubs available for everyone. The only downside is the price and availability, it sells out quickly, so hopefully they can keep up with demand.

This works great, I used it on my whole house generatior to notify me when and if the generator starts and stops.

We installed a YoLink water cutoff system in our Condo. The system consists of motorized values on the hot and cold water lines, a hub, and 8 leak sensors by all the sinks, toilets and appliances that use water. The app was easy to set up. Tests indicate that all is working well. So far, we are pleased with the system. There is every indication that it will work well if an emergency occurs.

These things have been a game changer for me. I use them all over the place in emergency situations to monitor temperatures all over our county. They have never failed me.

I used to have the grohe sense which were the worst imaginable unreliable problematic headaches. They also had the worst battery life. These are so much better.

Im using it with Home Assistant and it solved some problems. For example no other sensor (with wifi, zigbee or zwave) was reachable in my metal-mailbox. Also i'm able to use sensors in the basement now even if there are some floors inbetween.

Easy setup, reliable operation, and a great value as well. Sold all around device, will need to pick up additional units in the future as we expand our system.

Great product! Easy to set up and gives me so much peace of mind if something were to leak.

For stuff like this, what matters most to me is that it just...works. And it does! I have the sensor in my chest freezer and I used the hub on wifi only because we have a router with no extra ports unfortunately. It's working great and I have a lot more peace of mind now. Probably will buy a second sensor for the fridge.

I have not had time to install it yet but this is my second switch.
I live in a real remote area and like the fact I can turn on my outside porch light before I get home.
My second switch will be for above my sink so I can operate it remotely or use the timer option.

Door Sensor 2-Pack & Hub Starter Kit

I use these detectors under each toilet, each sink, and each refrigerator. In five years it has saved me from water damage on three occasions.

We 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.
