- World's Longest Wireless Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property.
- Easy and Effective Property Protection: The YoLink wireless Water Sensor could not be easier to install; just place near or under the equipment you wish to monitor. Suggested uses are near or under sump pumps, toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks and any other location subject to water leaks and flooding.
- Early-Warning Notifications: Receive real-time early-warning notifications (in the form of smartphone banner alerts, limited SMS/text messages, and emails) and protect your home and property from water damage; Due to the water-tight and submersible design of the original Water Leak Sensor, an internal sounder/siren would not be heard outside of the water-tight housing. For an audible alarm, consider our Siren Alarm or consider the Water Leak Sensor 2 which has a built-in sounder.
- Plug, Plug & Play! Plug Hub into an outlet, plug Hub into your router, scan in new devices, and enjoy your new system, in minutes! Your Hub is the only device that connects to the Internet, and a wired or WiFi connection is required (wired required for easy & fast Plug, Plug & Play, and most reliable and secure connection). WiFi connection set-up difficulty varies and requires changing settings to your network and/or your phone Changes to your network, passcodes, etc, require changes in the app.
- From Simple to Super-Smart: After setting up your notification preferences, keep it simple and let the YoLink system do the rest and monitor your home and property for you. Or, utilize available advanced automation features, including 3rd-party integration with Alexa and IFTTT, to interact with other YoLink and 3rd-party smart devices. Limited only by your imagination!

The instructions were simple. Download the app. Create an account. The in app hit ‘add Device’ and your phones opens up a camera scanner. Just aim it at the sensors backside and voila!! Plug the hub into internet cable ( or use wifi). Push a button for 5 seconds, then the app brings up your 2.4 wifi and asks for password. Enter it a boom- your done connecting. Now pick a spot for each sensor and push a tiny button the back. Boom connected. Name each one on the app. Set alarm to ‘on’ in the app. Add your phone number.
Now I’ve got a big house-5600 sq ft. . The hub is upstairs and about 80 feet from the the basement where I put sensor next to sump pump pit. It got a strong 76db signal from that far away and a level below in a finished basement. Wow!
I set it up so if a sensor gets wet it will text me and email me! I also added the YoLink skill to Alexa. I set it to have Alexa say on all my echos that there is an emergency water leak for each different location!!
Amazing and easy and I feel so protected now!! When I was setting it up I had a question, so I called the help number. Can you believe it? I got the designer of the system. His name is John and he was so helpful and patient and a pleasure to talk to!! Try that with a big box company!!
I’m so impressed with this company that I’m going to tell everyone! I’m giving this set of leak sensors and hub a 10++ and the customer service a 10++. The peace of mind I have from this product is awesome! Larry R. Chicago
When activated by moisture, the sensors triggers notification on device with YoLink app (for me it's my phone) and sends an email. You can determine how frequent this alert is repeated, and the sensor will continue to trigger notification and to send emails as long as wet.
There does not seem to be option for also sending text message. However, you could set email as mobile phone number if you prefer text message. The email address you would use depends on carrier: AT&T 10digitphonenumber@txt.att.net US Cellular 10digitphonenumber@email.uscc.net Sprint 10digitphonenumber@messaging.sprintpcs.com T-Mobile 10digitphonenumber@tmomail.net US Cellular 10digitphonenumber@email.uscc.net
The hub repeatedly dropped off WiFi signal. I think that issue was due to hub not being compatible with 5gHz signal. My WiFi has both 2.4 gHz and 5 gHz signal on same network. This issue might be solved by creating separate 2.4 gHz network. I didn't want to bother with that process so just connect hub with ethernet cable.
4 out of 5 stars for price, ease of use and functionality. 1 star off for lack of text message and WiFi issue.
(Please note that seller did provide free smart plug for posting a review)
I wanted a couple of water leak detectors for my well pump and my laundry room. My ultimate goal wasn't just to be alerted, but to have action taken if I had a leak. I have a TP-Link light switch controlling a contactor that turns on and off my 240V water well pump, so that when we're on vacation we can turn the well pump off. If we had a pipe burst, it's the only way we could keep our house from flooding, and I have one pipe that really bothers me with how it enters the basement...the 1" main line. So I wanted some assurance of flood prevention.
It took me about 2 minutes to get the hub connected to the iphone app and verified to be working. Then I added 2 of the water sensors which took maybe 15 seconds each, other than giving them a name. Very smooth. The only thing that I haven't figured out yet is why the SMS notification is greyed out. I can live without it but would like to set it up some time.
Once it was all connected, before I tested it, I went to IFTTT and within another 2 minutes I created my applets.
If - YoLink Leak Sensor (laundry room) triggers
Then - Turn off Kasa TP-Link Water Pump Switch
I set the sensor down, spilled some water next to it, and as soon as the water went under the sensor, it flashed, I got a notification that the sensor detected water, and IFTTT sent me a notification that it ran an applet. I checked my TP-Link switch and sure enough my water pump was turned off.
I'll tell you what...it doesn't get much better than this. My only fear is that this will end up being another flaky hub that gives issues with some firmware update or something, but, if the hub keeps doing its job, and these sensors get at least a year or two on their batteries and always work, then I'll consider this one of my favorite smart home integrations I've ever had! Thanks YoLink! Don't fail me!

Overall, very happy with these. I looked at cheaper options, but they had a lot of negative reviews.
I should give these a 4 due to the poor instructions in the box, however I did manage to figure out how to connect everything without using the online user guide.
To save yourself time and a headache, grab the online user guide first. It is useful and has good information.
These things work well. The batteries ARE replaceable and the user guide shows you how to replace them (AAA batteries). You can monitor the batteries right in the app.
It comes with 4 sensors. I put some water on a paper towel to test each sensor and they alerted right away. A notification pops up right on the main screen of my phone so you won't miss it and I have it set to send me an email as well. There are 2 sets of sensor probes on the bottom and one set on the top.
Update Oct 26. I bought these a few months back. Today I was alerted that there was a leak detected by the sensor I put next to my furnace room drain. Sure enough, I checked and the hose to my humifier had sprung a leak and water was accumulating in the room! Well worth the investment!
Love the feature that the hub can send notification through the app and/or SMS message when an event is detected. With the hub, now I will be adding door sensor as well.

Having a peace of mind helps. The only cons is, the alarm is dependent on your ability and Technical knowledge of you to setup.
You need to go to multiple pages settings and changes to get it right. App is very easy to navigate but it has room for improvement.
