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

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.

YoLink is a great product with many to choose from. I have water leaks detectors under every sink, behind every toilet, by the washing machine, AC pan and by the water heater. It has already alerted me to a leaky faucet.I also have temperature/humidity sensors in both my refrigerators and freezers. The refrigerator door was accidentally left open in my garage and the sensor alerted me when the temperature had risen above my set parameters. Saved me the loss of everything in my fridge!I also have the temperature float for my pool so I always know the temperature of the water. Love it!!They’re so easy to set up and use. Just love their products. I even got a discount on my homeowners insurance for having the least detection system installed!!I have already had a few friends and family also purchase and install YoLink sensors. They all are very happy with the system and its various uses and capabilities. Highly recommend YoLink. Their customer service should you need them is excellent! Couldn’t be happier with these products!

Excellent accessory that lets me have an audible alarm with door sensors, etc. Acts as a hub, too, to extend the reach of my other accessories. App is really easy to use and responsive.

I'm totally blind. The first thing I noticed about this is the box is square in shape and about 1 inch tall when sitting on a table. The power cord is a micro USB cord and plugs into the box with the points down. The box is meant to be set on a shelf or table. There are 3 buttons on the front of it near the front edge. The QR code is on the underside of it. There are little wholes all around the lower edge of the unit when sitting on a table.After plugging in the box and then trying to determine what the 3 buttons did! I found the left most is Volume down, the middle one I'm guessing is for configuring it being it didn't seem to do anything when pressed a few times. The right most if volume up.When into the App and scanned the QR code and then pressed the center button to get the hub online.The hub on its own doesn't give any voice messages or nothing like that. Tried that to see what it would do on its own out of the box. But again that could have been the way I have the sensors configured as far as alerts.Next went and played with the Automation smart stuff in the App to see what I could do.Yes you can create automation for the hub and have it play a sound along with speaking a written message that you type into the App on your phone. You can have the tone and message also repeat a few times if you like. You can also set the volume in the App, but that doesn't work for a totally blind person Being the controls doesn't work for a person using a screen reader. The nice thing is there is a test button that you can tap when setting up the sound/voice stuff so you can hear how it sounds. Default volume is whatever you currently have the hub set at if you have the volume box unchecked in the automation. So using the buttons on the hub itself and the test button in the App, set the volume to your liking and leave it.I found the speaker when doing this is on the underside of the unit and is facing down. The sound will hit whatever the hub is sitting on and then the little wholes around the lower edge causes the sound to come out all around the unit. So this unit should be set on a hard place like a table top or wooden shelf. Do not set it on something soft! If you do that, the sound will be soft and muffled.At highest volume, this may be OK for a single room. For me, this will not wake me up from sleeping being it takes something with more room filling sound to do that.If you want or need something with more room filling sound, you cannot connect an external speaker to this to help out with sound or volume.

I have nine Yolink sensors connected to this hub and I couldn’t be happier with my Yolink system. Yolink products are well made, accurate, reasonably priced, simple to get up and running, and if you ever have any issues, Yolink’s customer service is exceptional. I highly recommend Yolink products to anyone looking to purchase these types of sensors.

Overall, the hub has been great. Setup was super easy - added to network, and linked 2 temperature sensors for freezers. The sensors are about 40 feet away from the hub and connection is fairly stable. We've had a couple of drops of the connection of the sensor, but a quick button push gets them back online, and I am notified when they disconnect.
