YoLink Hub, 1/4 Mile Super Long Range Smart Hub LoRa Enabled Smart Home Automation Bridge Home Security Monitoring System - Central Controller for YoLink Smart Home Devices - White

Excellent build quality at a reasonable price and very easy to set up. The only criticism I have is about the mounting tape. It works too well as I found out when I removed the finger to slightly adjust its' position and it took the paint off right along with it. Not to worry though. It was on a garage wall. I did however use a double sided clear tape that can be removed easily to mount the other devices. A warning about the extreme grip of the included tape might be in order.All the devices I have purchased have performed flawlessly.YoLink first came to my attention when I watched Brian Read of Automate Your Life review YoLink products, I had been struggling with Smartthings and YoLink is the perfect replacement for my uses. The ease of use and setup allows people with marginal technical skills to begin automating their homes. Home automation will only take off when it becomes as easy as plugging in a new TV set. YoLink has taken a giant stride in that direction. I have contact sensors on outside doors, on a freezer door, motion sensor controlled lights in one room so far and a temperature and humidity monitor mounted in a protected spot on a covered patio. I also use a YoLink Finger to control my garage door. Changes in the state of these devices are announced on an Echo Show 8. I'm sure there will be many more YoLink products added soon.Another small mention. I noticed in several reviews on Amazon that people reported trouble scanning the QR codes. I had the same problem but discovered that the problem was that the place I was trying to do the scan, directly under a smart bulb set at 80% brightness, was too brightly lit. The problem was likely not the QR code but the camera on my cell phone. Moving to a room with only daylight filtered through a curtain cured the problem. The scan was instantaneous under those lighting conditions.

I needed to detect flooding on my patio, a left-open freezer door, and water leaks various places. I wanted to be alerted by text messages to my phone, notifications, and emails to me and other house occupants. I think you will find that getting such a combination in sensing and alerting is difficult to find. This company has offers all of this at very affordable prices. Also the user interface for their app is clear, the documentation is excellent, and the installation and setup are straight forward. I only had one problem in setting up the door sensor, but a quick call to the help line fixed that in five minutes. I am an electrical engineer, and very much appreciate the execution of these products, which have a lot of complexity going on under the hood. I cannot yet comment on the reliability, but expect they have done their homework in that regard too. I designed and built a soil moisture sensor for my own use that uses technology similar to theirs, with radio links and wifi connection to the internet. It was not an easy design. What a pleasure to just unbox their gadgetry, set it up quickly, and just have it work. Highly recommended.

great product for the price. Needed to add to existing hub

This is the main piece for the Yolink automation and monitoring systems. It's easy to set up as I have installed it in my equipment closet under the stairs to my attic right in the middle of my home. It gives plenty of range for all the devices and their interaction seems to be solid. My only concern as a former programmer is that they don't provide adequate written documentation. Right now they depend on YouTube videos. I am, though, very satisfied with the hardware itself and plan to use it. And the manufacturer has assured me that they will work with me to figure out the programming.Installed second Hub at end of House near generator whose metal cabinet blocked the signal causing an instability due to low signal strength. Problem fixed.

Having used a lot of home automation devices over the years (including X-10 and Z-Wave), this one is superior. Their installation process is quick and simple. They supply QR codes to get you started. The smart phone app is easy to use and intuitive. Another good thing is there are no fees to operate it unless you have a lot of sensor activity (high SMS traffic), but the fees are modest. I have heard that integrating to Alexa might be a problem but since I don't use that, I don't care.Having just installed it, only time will tell if it is truly a winner. However, since the hubs are inexpensive, I plan on getting a spare. I believe that installing a new or multiple hubs is pretty easy also.After using this for 6 weeks, I still find it to work very well. The only issue I have encountered is the area I am in has sporadic but brief power outages which can disrupt the operation of the dimmers and switches.

I bought the valve, controller and several sensors for a water link detection system from YoLink. I had an issue with the controller, and YoLink quickly sent me another which solved the problem and now the system works very well. Contact with their tech support was quick and easy both online and by phone, which earns huge points in my book. No long wait times, they were very quick to answer my call and very quick to respond to emails, and they solved my problems and answered my questions very well. Good customer service - 5 stars. I wish all companies had this kind of service. I later bought the hub and another sensor and added them to the system. The installation was a breeze. Couldn't have been easier. The products were well made and well packaged and easily connected to the hub and the app. A hint that I would pass on if you are pairing sensors to the controller without the hub and app: Close the valve first, then pair the sensor to the controller, then open the valve and then test with water on the sensor contacts. Repeat for other sensors to install. Don't try to pair with the valve open is the key - be sure it's closed. Thanks YoLink for a good product that does exactly what it's supposed to do and at what I believe is a very fair price.
