YoLink Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

Water damage is one of those home disasters you don't think about until it's too late. The YoLink Water Leak Starter Kit changed that calculus for me completely — and the relief it provides is hard to overstate. Setup was remarkably straightforward. Getting the hub and four sensors up and running required minimal effort, which matters when you're dealing with hardware that's going behind appliances and under sinks. No wrestling with complicated configurations or cryptic instructions. The real magic is what happens once it's all running. If a sensor detects a leak, it automatically triggers the main water shutoff — no intervention needed, no frantic rush home, no crossed fingers. That automatic response alone is worth the price of admission. But on top of that, I can shut off my main water supply manually from anywhere, whether I'm at the office, on vacation, or just away for the weekend. That kind of remote control over something as critical as your water supply is genuinely reassuring. The LoRa long-range connectivity means the sensors stay reliably connected even in spots where other wireless devices might struggle — basements, utility rooms, far corners of the house. And the Alexa integration works seamlessly, adding another convenient way to interact with the system without reaching for your phone. If you're a homeowner who wants to stop worrying about what might be happening to your house while you're away, this kit is a no-brainer. It's practical, it's reliable, and it delivers exactly what it promises. Absolutely worth every penny.

I’ve been very impressed with this Wi-Fi water valve system. It connects seamlessly to my phone and allows me to remotely open or close the main water supply to my house, which adds a great level of convenience and control. I paired it with a compatible water leak sensor to create a smart leak detection system. I also integrated everything with Alexa, so if a leak is detected, Alexa immediately announces an alarm both in my home and on my phone. At the same time, the system is set up so the valve automatically shuts off the water supply—even if Wi-Fi or power is down—which gives me extra peace of mind. I’ve only been using it for a few months, so I can’t yet speak to the long-term battery life of the sensors. The valve itself is connected to a 110V power source but includes a backup battery to operate during power outages, which is a great feature. Overall, I feel much more comfortable knowing my home is protected against potential water leaks. It’s a smart investment for anyone looking to prevent costly water damage

I’ve had a great experience with the YoLink Water Leak Starter Kit so far. It provides a level of peace of mind that is well worth the investment. I have sensors placed in several high-risk areas, including near my water heater. While that hasn't leaked yet (thankfully!), I also have a sensor tucked under my refrigerator. My fridge occasionally leaks water, and this system catches it and alerts me right away. The instant notifications are fantastic because they allow me to address the issue immediately. It has already helped me prevent larger cleanups and, more importantly, potentially serious water damage. Pros: Instant Alerts: The speed of the notifications is impressive. Easy Setup: The hub and sensors were straightforward to get up and running. Preventative: Truly helps stop a small drip from becoming a major headache. If you're looking for a reliable and responsive leak detection system, I highly recommend this starter kit!

We bought the YoLink Hub + Sensor kit to monitor our attic water heater setup, including the T&P valve, cold water pipe, hot water pipe, and drain pan, as well as the water level in our basement sump area. So far it has worked very well. The biggest benefit is peace of mind. These are areas we do not check every day, so having reliable alerts makes a big difference. Setup was straightforward, the sensors connected without much trouble, and the system has been stable. Notifications have been timely, which is exactly what we wanted. If you need monitoring for places like an attic, utility area, or basement where early warning matters, this system is a great choice.

These leak sensors work well. The setup with Home Assistant was quick and smooth. I've got them monitoring my hot water heaters and two sinks. I tested them by dripping some water nearby, and they reported these "leaks" very quickly. This gives me high confidence in the sensors' ability to detect accurately. The only thing I've noticed is that they give false reports every now and then, indicating that a leak has occurred when it has not. This happens perhaps once every couple of month; that's the only reason for 4 stars as opposed to 5 stars..

This Yolink water leak sensor system is really, really, excellent. I installed the hub and four sensors about a week ago and I am impressed. I first noticed the info about its LoRa radio link between the sensors and the hub. As an engineer I wanted to understand more about that technology. First, could it reliably maintain the link for that kind of distance, and second, can it do so with such a small battery draw to make it sensible for battery only powered sensors. If you read about LoRa on Wikipedia, along with the Chirp transmission method, you can see why it’s exactly the right radio link for small battery powered sensors at a long distance. It’s the same type of low speed data link that scientist use to track tagged animals in the wild. They need a small battery powered transmitter to chirp a few bits of data for as long as possible and over the longest possible distance. LoRa does that. And now the people at YoLink have used the same technology to build what appears to be the ideal system for homeowners to prevent a water leak from destroying property. One tech note here. When I first deployed the sensors in a guest house about 150 feet from the hub in my main house, I saw that the sensors were running with a radio link receive level of about -37dbm. That info is available from looking at the phone app. That is a very strong signal despite five or six walls and150 feet distance. However over about a day I noticed the radio link level dropped down to about -100 dbm. Even though one would think that is a low level, it’s actually still a good signal for a LoRa link. I think YoLink has done a very cool trick and have the sensors drop the transmitter level over a period of time in order to conserve battery life, at the same time still maintain a solid data link. That is why they are able to get years of life from a set of normal batteries in the sensor. It’s the perfect way to operate the alarm system. Loved the wired Ethernet connection option also. I suggest you use it instead of Wifi for the hub. I was so impressed with the initial hub and sensors after a couple of days I decided to go forward with purchasing the siren and water valve cutoff unit. I now have those in place and tested multiple times. The whole system works perfectly. When I place a moist paper towel under one of the sensors it alarms within seconds, the siren goes off, the water valve closes, I receive a notification on my iPhone, and an email as well. All four sensors were tested that way and they all four worked flawlessly. The hardware seems really high quality. Fit and finish, the cables for the hub and siren, and the sensors look to have good sealing to maintain the batteries in a dry and solid housing. I understand changing the batteries will be simple with just removing a few screws and taking the sensor apart. That is way better that just a clip like battery cover design. I did notice that the water valve hardware is not stainless steel. That will not be a problem if your water valve is inside, but mine is mounted outside. I plan to build a small housing to fit over the water valve to keep it out of the weather, along with keeping the steel hardware greased to prevent corrosion. But for the price, I think its an amazing device and system to same you from the disaster of water damage. Now a word about support, After I received the siren and water valve and got them paired to the hub it was not exactly clear if they were ready to automatically do their thing when a sensor alarms. So I called the support line and right away Clair answered and within a few minutes explained the process of getting things properly set up for automatic siren and water valve operation. She took the time to capture and send me screen shots of the app and stepped me through the process. The key is clicking on the Smart button on the app, then the automation button, then + to add a rule for each sensor. It’s quite easy if you just hit those buttons in the app. Setup took no more that a few minutes. Thanks Clair. I get the impression that YoLink has set the standard for a perfect water leak prevention system. The fact that’s it’s low cost is just an added benefit. And another note. My work involves taking care of high powered water cooled television transmitters across the country. I am planning to install YoLink sensors in every location. The cost is so low I will just add it to my monthly expenses. It’s not even a capital expense to do such an important upgrade to my remote sites. Just get the things, you will not regret it.

If you are running the YoLink system, buying more sensors is not a maybe it is a must. I picked up this 3 pack to cover the rest of the house and it was a no brainer. Setup took minutes, they synced right up, and now every risk area is covered. Under sinks, water heater, laundry, you name it. These things catch leaks fast and alert you within seconds through the app. Pair that with the automatic shut off and you are basically shutting down problems before they turn into expensive lessons. The range is legit too. No signal issues, no drop offs, just solid performance. At this point, if water gets loose in my house, it is going to have a bad day not me. Bottom line, if you already have the system, do not cut corners. Get the sensors and cover everything.

These are the best. Quietly deliver notifications, easy to suppress as needed. I bought 3 sets so far and I plan to buy more so that every accessible water pipe or toilet has one. These have saved me tens of thousands of $$ in damages. Super easy to connect. Never had a problem with the range, as this technology seems to pass through the walls unlike the WIFI. The only problem is that I cannot buy sensors in bulk. The “starter kit” is the cheapest even though it comes with an extra hub that I certainly don’t need after the first kit. A single hub covers all sensors in the house. I like that the batteries are replaceable, but I haven’t tested it yet, as these last many years.

Excellent product. Easy to install easy to use and setup. Highly recommended.

Notifications are excellent and very accurate when detecting water

Works well once reset to Europe wifi but it would not connect with their European/UK hub without a fair amount of resetting and liaison with tech support. I was expecting this so was not a problem for me.

Works very well and detects water, notifications are excellent
