YoLinkHub, 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

YoLink has many home monitoring systems including water links, video and thermostats. I use only the water leak detection system. The system uses an app to program and control leak detectors that automatically detect and send notifications to email and mobile phone. I also installed an online inline automated water valve to turn off the water if a leak is detected. I have placed a detector near the washing machine, the refrigerator and dishwasher, and the water heater. Basically, anywhere there could be water leaks, there is a small detector. The detectors also have great range. I even put one near the intake from the well to monitor for frozen pipes.The system works extremely well. It will also connect to the internet to allow for online control anywhere there is internet. However, internet is NOT needed for the system to detect and turn off the water. But is needed for online control and notification. Not sure if you can set up for a phone call notification.The valve cutoffs are very good quality and work flawlessly. I have the model that allows you to simply fit it to the existing cutoff valve. This setup allows for a simple install usually without a plumber. There is also an improved inline cutoff valve that sadly was not available when I installed my system. This newer improved model completely replaced the existing cutoff valve. Or you could install the new inline valve in addition to the existing valve. Mine is in the pump house but it can easily be installed in the water cutoff box coming from the street.The system worked well for multiple years until I began having “detector offline” notifications. YoLink support worked immediately with me to diagnose and solve the issue. They even added an additional hub at their expense.All in, a very well designed and constructed system with excellent customer support. The app is also top quality. I would definitely recommend YoLink for instant peace of mind that your home will not be flooded while at work or traveling.

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.

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 got this device because the older version did not have direct (cable) internet capability. The inability of these devices to connect to Wi-Fi systems faster than 2.4 GHz is a real problem. Fortunately, if you connect to your router using a cable, you can connect to routers faster than 2.4 GHz. The other issue is the app. The app is weak, and it may take several tries (delete & add device) to get it and any sensors to work. The third issue I have is that the basic model no longer has a siren. So, you need to buy a different hub to get the siren or you need to buy a separate siren like I did.If you can overlook these issues, then you will be happy. I use mine to protect my car at night, and it allowed me to catch 3 young men breaking into my car two weeks after I got the unit. The siren went off, and I scared them off, gun in hand. Since then, there have been no more attempted break-ins.
