- Reviewed in the United States on March 20, 2025Style: Water Leak SensorVerified PurchasePart of this review is about the device and the other is about the customer service I received.
The guys that plumbed our house 30+ years ago used substandard materials and coupled that with shoddy work. We have had several leaks in various places in house causing thousands in water damage over the years. I have used the basic battery operated leak sensors and they work well enough but you have to be home for them to do any good so I have been searching for a way to detect leaks when we are away. I tried using a Zircon wifi leak sensor but it ate batteries like I eat cookies and it didn't always alert me when the batteries needed to be changed, It was also much more expensive than these Tapo sensors. It sent alerts through email and you do not always see those for a while so after just a few months, I stopped feeding my unit batteries.
I decided to give these Tapo sensors a try because the Tapo hub requires a very low power usage to stay connected and you can use their phone app to check the battery strength. I have had these for several months now and the batteries strength is still practically new. I have one behind every toilet, next to the water heater pan, washing machine, dishwasher and under each sink in the house (and I am going to order a few more because I just thought of a couple places that might benefit). I do test them occasionally either by simply putting a wet finger across the contacts or setting them on a wet surface just for piece of mind that they are still operating and they always trigger an alert on my mobile devices (iphone and Ipad). The leak notification pops up almost immediate on my phone. They also have a test button which allows you to just test that the device is working and communicating with the hub. Getting a leak notification when you are away is a game changer which I hope will help avert a disaster because you know that these things usually happen when you are on vacation. Now I can get my neighbor to run next door and turn off my water to minimize damage. I cannot believe how cheap they are.
Except for one unit, the setup process for these through the app was about as easy as it can get. Within minutes, it was activated and sending alerts when I tested them. I disconnected my phone from WiFI to also test that I got alerts when away. Unfortunately one unit activated but had a "local only" error status meaning that it would not give me updates while away. The good news is that the app was smart enough to know that there was a problem and flagged it with a big red flag but alerts would trigger on my phone only when connected to WiFi. I contacted their customer service and the assigned tech seemed to take this problem personally and over a few days (not sure they had seen the error before) of doggedness got it working as it should. The dedication that CS tech Graham showed to solving this issue has given me the confidence to invest in other TP-Link smart home devices. I now have several others and the Tapo/Kasa and TP-Link ecosystem in my home continues to grow.
I have tried several different smart home brands over the last 5 or 6 years and the this one gets my vote as the best envisioned so far. Note that I also use Alexa for some automatons and these devices work seamlessly with Alexa as well. My only complaint is that the automatons you can create in the Tapo app are still evolving but Alexa fills that void nicely for now and there has been nothing that I wanted to do that I could not. Also note that TP-Link has an excellent forum for asking questions. TP-Link is dedicated helping people utilize their technology by answering questions there but you also get other users providing input as well which greatly enhances the knowledge base.
- Reviewed in the United States on October 24, 2024Style: Water Leak SensorVerified PurchaseWe have not had a water leak yet, than goodness. I tested each sensor and they all responded.
They were very easy to setup on my mesh network. The app found all my old Kasa light switches and added them automatically, Now I have both set of devices on a quality app.
I have had smart devices from TP-Link. They also make a good devices and apps that work well.
When testing them, the sensors sent a notification to my phone, so in addition to a loud alarm it will let me know even if I an not home.
I had previously tried to setup the top rated Moen water sensors. I spent at least 3 hours on tech support calls with them. They even decided the first ones I had were all defective and sent me a new set. These also would not connect to my network. The reset button is poorly designed and hurt to press, and I had to press it a lot.
This is much better and it seems to work. I hope I never have a water leak but I feel much better prepared now. I had 2 water leaks at our previous house and they were very expensive to repair. This was easy and inexpensive.
- Reviewed in the United States on April 1, 2025Style: Water Leak SensorVerified PurchaseI've been using the TP-Link Tapo Smart Water Leak Detector for a few months now, and I can't recommend it enough. It’s a small device that packs a big punch when it comes to peace of mind.
Setting it up was a breeze; I had it connected to my Wi-Fi in no time. Once it's up and running, you can place it anywhere you suspect water might be a problem, like near hoses, sinks, or in the basement. The real magic happens with the notifications. If it detects even a little moisture, it sends an alert straight to my phone. That feature really gave me confidence, knowing I could catch potential leaks before they turn into major issues.
What I appreciate most is how sensitive it is. I've tested it a few times, and it picked up even the smallest drops of water. Also, the battery life has been impressive; I haven't had to replace it yet, which is a plus.
And since it's part of the Tapo ecosystem, it works perfectly with my other Tapo devices, so I can monitor everything easily through one app. Overall, if you're looking to safeguard your home from water damage, this little detector is worth the investment. It’s reliable, efficient, and just makes life a bit easier!
- Reviewed in the United States on July 31, 2024Style: Water Leak SensorVerified PurchaseThis sensor is better than others I've looked at, for a few reasons. It's surprisingly easy to set up using the Tapo app. I particularly like that if it detects a leak, it alerts on the sensor itself (loudly), the Tapo hub (which can be located where you can best hear it), and my phone. After I set it up in the app, I set it in a puddle, and got alerts in all three places within 1-2 seconds.
During setup, the LED would not come on. The app prompted with suggestions for resolving this, and it turned out that one of the batteries had been installed in the wrong orientation. As soon as I installed the battery correctly, the setup completed as expected. If you run into a setup problem, don't assume the factory installed the batteries correctly.
- Reviewed in the United States on March 23, 2025Style: Water Leak SensorVerified PurchaseAwesome devices, work great, communications with hub solid.
- Reviewed in the United States on December 7, 2024Style: Water Leak SensorVerified PurchaseThe title says it all. Pulled out the blue tab. I could not get the device to power up. Turns out, the batteries were installed backwards. Definitely a QA issue at the factory.
- Reviewed in the United States on April 20, 2024Style: Water Leak SensorVerified PurchaseFirst and only con: batteries dead on arrival (easily fixed)
Pros: extremely easy Setup with hub. Placed the device in our sump pump room in the basement, hub is main floor, test worked perfectly for connection. Dripped some water on the top sensors and received an immediate alarm at the sensor, hub and phone. Will order a second one for the water heater in the equipment room. I use a Deco X55 mesh system and have created an IoT network for this device and all my Kasa/Tapo devices. Runs like a charm.

on my other TP products I bought this item needs to attach to a another unit. All of my other TP products attached directly to my phone.
There was no mention of requiring a second unit in order for this to function. If that were the case, I may as well have gotten the more expensive newer model.
I will be returning this model due to the fact it was poorly advertised, and not what was expected.
In my opinion, this item deserves no star due to incomplete. The explanation on the site deserves one star, or the retailer deserves one star or poor information.
