YoLink Water Leak Sensor 1 Kit: 6-Pack + Hub

After a colleague had a MAJOR leak that caused a lot of damage, I decided to get water leak sensors and picked the YoLink ones after a lot of reading/research. So far (about a month), I've been very happy with them. They were easy to set up and connect, and I tested each one by setting it in water to be sure it worked. All triggered a leak alert to my phone. We bought this starter kit as well as additional sensors to cover all anticipated leak locations at home. We connected the hub via ethernet to our router for stability and so far, all has worked well and has provided peace of mind for a reasonable cost. Initially, we had some trouble with losing the Internet connection, but then I discovered that it works best when plugged in using the actual plug - not just inserting the USB end into my power strip. Using the actual plug provides more stable power and since doing that, I have not had trouble with losing the Internet connection. When our Internet goes down (e.g. a storm or a need for a reboot), the YoLink router comes back smoothly most of the time. If it doesn't, unplug the hub from the router, reboot the router, then plug the modem & router back in, plugging the hub back in last.

I cannot recommend the YoLink Water Leak Starter Kit enough. After dealing with a minor basement leak last year that went unnoticed for two days, I knew I needed a reliable detection system. I did a lot of research before settling on YoLink, and honestly, this system blows the standard Wi-Fi sensors out of the water. Here is why this kit deserves a full 5 stars: LoRa Long-Range Technology is a Game Changer: This is the main selling point. Unlike standard smart home devices that struggle to stay connected in my basement or utility closet, the LoRa (Long Range) tech punches through walls and concrete with zero issues. I have one sensor in a detached garage about 100 feet from the house, and it has full signal strength. Ridiculously Easy Setup: I am not a super technical person, but I had the Hub and all 4 sensors up and running in under 15 minutes. You just scan the QR code in the app, and it connects instantly. No fiddling with complicated Wi-Fi passwords for each individual sensor. Silent but Deadly Accurate: Note that these are the "Silent" version of Sensor 1. They don't scream at you with an onboard siren, which I actually prefer because I have pets that would be terrified by a loud alarm. Instead, the Hub handles the audio (if you want it to), and the phone notifications are instantaneous. I tested one with a wet paper towel, and my phone buzzed within 2 seconds. The App is Fantastic: The YoLink app is clean, intuitive, and lets you set up all sorts of automation. You can even configure it to send emails or texts to family members if a leak is detected while you are on vacation. The Bottom Line: For the price of a single plumbing visit, you get a Hub and four reliable sensors. If you own a home, this isn't just a gadget; it is essential insurance. Do yourself a favor and buy this before you need it!

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.

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!

The system is fairly easy to set up. It probably took me 20 minutes with 4 sensors. I ended up using the cable to connect the basestation to my router after some trouble getting connected tirelessly. The system has been in place a few months and already helped detect a leak under the kitchen sink that could have caused significant damage. We would not have found this leak without the YoLink system in place. I am considering buying another set. Definitely recommend this product.

YoLink water leak sensors are very well designed, perhaps one of the best design in the market. I have a couple of water sensors from other brands, and none of them have a pair of sensor electrodes ON THE TOP. Each Yolink sensor has three pairs of water sensor electrodes, one at the top, two on opposite sides at the bottom, so it maximizes the chance of detecting any leak nearby. It also has a small footprint and easy to fit most areas that you need them. The instruction manual is easy to follow. I got the devices set up in minutes. I tested each unit with damp cloth or drips of water. Each unit gives an alarm right away, showing high and reliable sensitivity. Note that the alarm only went through the App (you can set up email alerts for free too if you like). I'm not sure whether it can produce an audible alarm yet, but I don't really need them and prefer App alerts anyway. I did sense bell-like buzzing noise when they were shook by chance, so I think they may be physically capable of giving audible alarms. The build quality and QC looks really good. I bought them for about six months now and they haven't got a single issue, so I would say they are pretty durable too. Finally, the App and signal transmission is also one of the best design among all the IOT devices out there. I connected the hub to the internet via Ethernet, so I don't need to worry about bad Wifi. The sensors are connected to the hub via a lower frequency 923.3 MHz RF, so the signals are excellent at penetrating multiple walls and ensuring devices stay connected within a wide range. The app is well designed, responds fast, and easy to use. I also love that each device shows its signal strength and battery level on the home screen, very convenient. Overall, I would highly recommend this product.

I needed to monitor for water leaks, keep track of the temperature in my deep freezers and greenhouse, monitor the water level and the temperature in the chicken coop, and know when several gates and doors were opened (and closed). YoLink covered all of it, and does it well. The battery life and range are exceptional. I am monitoring locations spread around my property with no issues. I have a speaker hub in the house that gives audible alerts when there is a problem, and I get notified of all alerts on my phone (via the app). I ended up with a sensor under every sink and behind each toilet, at the water softener, and washing machine. Temperature sensors in all 3 deep freezers and both refrigerators. (Can you imagine a freezer failing that you only go to about once a week? If there was a problem, I would get an alert while there was still time to move the contents before they were destroyed.) And best of all, it just works. It was simple to install and set up and there have been no problems with the equipment. My only complaint is that they are still out of stock on smoke detectors. I found all of this because I was searching for a remote monitored smoke detector system. Having a detector sounding in a detached garage or garden shed is of no use. With YoLink I will know if there is a problem wherever I happen to be. (If YoLink is reading this, hurry up and restock smoke detectors!!!) I highly recommend this product.

Fantastic! Super easy to setup, get connected and get going. Directions are spot on and the app works as it should. Tested each sensor after setup and the alerts were super quick. Works with Google Home too. Overall couldn't be happier.

Happy with the product as it has help deck about 5 leaks so far in 4 years. I keep these sensors in under sinks and in sump pump area.. batteries still show about 80% full after 4 year mark.

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.
