YoLink DIY Automatic Water Leak Detection & Shut-Off Starter Kit, Valve Operator, Wireless Valve Controller, (3) Leak Sensors, Hub

Easy to install, works excellent!

We are not home a lot. I have a flume water monitor (purchased in Amazon). Thee flume gives you a push notification when water has been running more than 20 minutes. (You can set up the notification time period.) When you are not home and get this notification you can see how many gallons of water is running. This is where YoLink comes in. You open the YoLink app and can shut off the main waterline for the whole house. If you don't have a flume, YoLink has small water leak monitors (see photo). You can strategically place them where a water leak can occur, such as under toilet or under a sink. (Four of these come with YoLink and additional ones can be purchased.) When these little disks detects water it sends a signal to the main YoLink and the main YoLink turns on and automatically shuts off the water main valve. The YoLink and disks are easy setup. (Takes about 20 minute and no technical knowledge is needed.) Everything connects to your WiFi easily. It's very intuitive. There is very good customer service if you need. It is well worth the small cost. Ours has been working flawless for several months now. We test it monthly by using the app to turn the water main off and on again. The main YoLink at your water valve must be plugged into an electrical outlet with or without an extension cord. The unit also needs WiFi. As one last note, make sure you check your main water shut off valve. This unit works with a main water shut off valve that has a lever handle to shut it off. (See photo.) YoLink also has other units for different types of shut off valves. If you are unsure of what type to purchase, just give them a phone call.

the valve controller i received is look like used before , there is scratch in the back side , advise me how i can share with you the photo

Easy to install, works well. It has triggered once accidentally (someone spilled water on the sensor), and was easy to reset manually and via app.

This was an easy DIY install and gives peace of mind because it can automatically detect a water leak, send a notification, and close the main water valve to greatly reduce the risk of extensive damage to the home. By far the hardest part, and it was still easy, was installing the valve operator (see photo) onto the existing main water valve. Adding new devices, such as leak sensors, is simple as can be, just scan the QR code on the device using the YoLink app, press the power button, and it's connected, works every time with no glitches. All of the devices are either battery powered or have battery backup, so will protect your home even when there's a power or internet outage.
