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

Due to a water claim for the previous owners on our new home, we needed to add an automatic water shut off device to get insured. We didn't have have the ability to do invasive work on the plumbing and all the other products needed to be installed by a plumber or a very confident diy-er who was willing to gamble with something as high risk as the main water line whuch we were not comfortable working on. The last thing you want is to make a mistake on something like this. Due to this requirement we decided to purchase this product but were honestly happy to do so. Our minds are at ease knowing that if there's a leak this device will not only notify my where- depending on where I install the little sensors, but also shut the water off entirely. Smart controls are fantastic you can set automations and decide if you want to be notified or have it shut the water off automatically. What's also nice is that you can have it powered with regular batteries, so there's no need to deal with wires everywhere, or finding an outlet nearby, or water proof connections- which I also didn't have where my yo link is now located. I believe the battery can last up to 2 years but even if it's just 6 months I wouldn't have an issue with it seeing as how convenient this is, I can't complain whatsoever. Powerful little device, gives me peace of mind and with all the other housework I'm doing by myself, it's nice to ask Google to shut the water on or off to test what I need to when working on minor plumbing repairs. Price is great and it's more analog than other devices since it uses water sensors and manually shuts off the water, but it honestly gives me more peace of mind since we know if it's wet it's going to set off the automation or alarm without a doubt. If it's running low on battery you'll see it right on the app. Huge plus is that you can place these sensors anywhere! I'm planning on purchasing more to add to my garage in the future! You can't go wrong with this. Good quality, easy to use app, easy to install, integrates with my Google home ecosystem, sensors can be placed anywhere you want giving you full control. Comparable products can be $500+ and that's not even including install which would have ran us another $600 at best. Whether you need it for insurance or for peace of mind. The cost of this is well worth preventing future damage that can occur by not having one installed. Oh and I can attest the sensor work great! Kids were splashing water a bit much in the tub. Wet the floor and just like that all the water was shut off immediately. Sensor works by water either falling on it or water poolibg under it so it can be placed under sinks or areas where leaks can occur, or directly on the floor like in a bathroom! Can't recommend this enough. You won't regret it and might even save you future headaches!

This device is life changing. I researched extensively compared to MOEN, and YoLink is head and shoulders above! Relies on device to device communication, not wifi, back up battery, and no false alarms (that the other brand is known for false alarms and things like the water shutting unexpectedly or hard water causing false readings) With YoLink you put sensors where you want, you select if you want the water immediately shut off or a warning first etc. The other brand relies on automation/ you don't control all actions (people reported they often needed to call a plumber). YoLink on the contrary got stellar reviews. YoLink leak sensors are available in puck style or rope style, audible or not. I LOVE MY YOLINK!! I had an entire pipe burst as I boarded a plane at thanksgiving this year - in the 30 min time when I got alerted from my previous leak sensor and scrambled to call a neighbor to run to shut my main, I had catastrophic damage. Whole house flooded, standing water inches deep. Yes I had sensors so I got "alerts" but I needed to get someone to the house. NOW with YoLink, the main is automatically shut off IMMEDIATELY at the first detection of water. Within seconds, the main is shut. I have my sanity back. After the flood, before I discovered YoLink, I was manually shutting my main off every time I left the house. But honestly even while you sleep, or run to the store is enough time for a burst pipe to do thousands of dollars of damage. Now the response is immediate. Leak detected = water off! You can also control the shut off valve from your phone but the entire system is automatic. I LOVE YOLINK! I finally have peace of mind. I cannot say enough about this device. It's flawless.

I purchased this kit after noticing some minor plumbing issues around the house and wanting peace of mind, especially when traveling. The bundle is comprehensive right out of the box: three water leak sensors, a smart valve controller, the EVO Valve Operator, and the YoLink hub - everything you need for leak detection, instant notification, and automatic shutoff to protect your home. Installation was easier than I expected. The EVO Valve Operator attaches to your existing shutoff valve without cutting any pipes, which was a huge relief. I had the hub configured, sensors placed, and the valve controller paired in well under an hour - no plumber, no contractor required. The included instructions are exceptionally clear, and this was honestly the easiest setup of any home automation system I've owned. Then it earned its keep almost immediately. About a week after setup, a bathroom sink connection started leaking. I got an alert on my phone right away, found the source, fixed it myself, and walked away with zero water damage. Without this system, I wouldn't have discovered it until water had already worked its way through the floor - potentially thousands of dollars in repairs. A few standout features beyond that core experience: Device-to-Device (D2D) communication is a game-changer. The sensors and valve controller communicate directly with each other, independent of your internet connection or power. If a leak is detected during an outage, the valve still closes automatically. That's real protection — not just an app feature. LoRa range is impressive. YoLink's technology covers up to a quarter mile between devices and the hub. I placed sensors in areas where Wi-Fi-based sensors would struggle, and every one connects without issue. Battery life is outstanding. Leak sensors are rated up to 5 years. The valve controller runs up to 2 years on battery, with a wired power option that serves as backup — no interruption even during outages. Notification options are flexible. SMS, app alerts, and email are all configurable per device. iOS users also receive Critical Alerts, which cut through Do Not Disturb - exactly what you want at 2 a.m. when water is pooling somewhere. No monthly fees! The kit includes 30 free SMS alerts per month (5 per device) and integrates with Alexa, Google Assistant, IFTTT, and Home Assistant without any subscription requirement. If you've ever dealt with a slow leak that went undetected, or worried about water damage while away from home, this system is exactly what you need. The combination of automatic valve shutoff, long-range sensors, and offline D2D communication makes it genuinely comprehensive - not just a notification tool, but an active line of defense. Highly recommend.

This thing is great - I had used a couple of other styles (wifi, zigbee) but the valve attachment mechanism was not as secure and the signal unreliable. My valve is in an in-ground box outside and the other ones each died within a few weeks each - this one has been going strong for at least 6 months. The yolink app is intuitive enough and the sensors are immediately responsive and have not gone offline once - in fact they are so reliable that I've bought about 20 other yolink devices (leak sensors, smart hose timers, thermometers) since getting this valve, and they all perform flawlessly. The ability to link leak sensors directly to the valve without meeting to go through the Internet is crucial and works great. And as much as Alexa sucks, yolink integrates with it and I believe it can be made to work with Home Assistant.

The hardware is easy to mount and install (1" copper supply before the water meter) and wiring connectivity between the valve, operator module, set up the wireless connectivity through the hub was pretty easy. The power connector and connections have been pretty stable. Pairing with the app was easy. The features in the app are intuitive to use. Actions work reliably well and are accurate. I have configured 1 leak detector for now and will be setting up couple others soon. Overall, the app is intuitive and handles everything maturely. These are a bunch of good products with good quality material and gives me peace of mind.

I had an excellent experience with YoLink's customer service and wanted to share my appreciation. After experiencing an issue with one of my water shut-off actuators, the YoLink support team responded quickly and professionally. They promptly processed a refund, sent a replacement device, and provided a prepaid return label for the defective unit. The replacement actuator arrived quickly and is working perfectly. What impressed me most was the quality of their customer support. I was able to reach a knowledgeable and friendly representative by phone on a Sunday, and their email support was consistently prompt, thorough, and courteous throughout the entire process. I've been very happy with YoLink's products overall. Their water leak detection and automatic shut-off system provide tremendous peace of mind and have become an important part of protecting my home from potential water damage. Thank you to Phoebe, Clair, and the entire YoLink team for your outstanding quality team-oriented service and support. It's refreshing to work with a company that stands behind its products and truly cares about its customers.

I’ll start by emphasizing great customer service. I had a minor issue with my order. The kit I purchased included four sensors but only three arrived. I contacted the company, they apologized and within two days the additional sensor was on my doorstep shipped all the way across the country. The system installation and set up was a breeze. It could not have been easier. I tested it after set up and it worked exactly as described, no issues. The app was an easy download and allows me to see and control the system from anywhere. Great piece of mind because we once had a water heater leak and it was a long cleanup. Now with this system any future leak will be minor as it shuts the water down immediately. I highly recommend this company and their products.

I did a lot of research before choosing the YoLink shut-off system. And I am very happy I purchased the system. Within two weeks of having it installed (I had to have a plumber install some lines, as I had very little room), the system alerted me to a leak in the master bathroom toilet and another leak underneath my kitchen sink. I have YoLink sensors placed everywhere in my house where that potential for a leak would happen. The device is easy to install, and the app on your phone is really easy to follow. Amazing how it works when it senses a leak. The valve closes within seconds and alerts you to the exact location of the leak. Simply an amazing product. I also had to call their service department for a small issue with setting up the app, and to my amazement, a person answered within seconds and fixed the issue with great instructions from a very pleasant person. Thank you, YoLink, for a great product that I highly recommend.

Easy to install, works excellent!

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.

Excellent system, if you’re not r teck savvy get a friend to go through the setup together everything connected easily once I figured out the instructions lol

I purchased this diy water leak detection and shut-off start kit recently, it is very easy to setup the controller with the new water leak sensor, firmware version 0361. However during the time when do D2D pairing between the controller and the sensors, the connection is not working with my old sensors firmware version 030a. After talked to Yosmart support and the issues are fixed after they issued new upgrade from cloud to the my sensors in questions. During the time of troubleshooting, I can tell their team is very friendly, incredibly knowledgeable and provided the detail instructions step-by-step. Also, Mr. Thomas from Yolink support should be given 5 stars service award, he has been helping me out to get the issue sorted out finally. Yolink's products are highly recommended and I have been using their products over 5 years without having any issues, it will bring peace of mind regardless you are at home or away on vacation.

Simple setup, works as advertised. Purchased after washing machine failure. This was super easy to setup and works great. Valve response is pretty quick. Alerts you on your phone and closes the valve automatically.
