Inexpensive sensor that just works as it should. Customer service was fantastic.
Part 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.

Easy setup and monitoring.
I’ve kind of committed to Tapo and Kasa for remote control for lights and environmental monitoring for house. This, along with the temp/humidity monitor gives me peace of mind when I leave the house. I can see and control the status of the devices (4 lights inside and out along with water sensor and temp/humidity) from my phone anywhere with internet access. You just have to have the hub for anything but lights. All very easy to pair through the Tapo app. Kasa and Tapo work well together. Picked up my home wi-fi quickly and easily. They off a nice line of quality home monitoring products at reasonable pricing.

Reliable, TP Link quality
There are lots of water detection devices on the market today. I have other TP Link products in use and they have not disappointed so I thought I would give these a try. The software is top notch and constantly updated. I have a high deductible homeowner's policy and installed four of these for a piece of mind. I travel a lot and felt like this was a good investment. Interestingly, one of them went off the first night as a result of a very small, occasional leak in my kitchen sink. The alarms are quite loud. Long term, that leak could have been a problem. These seem reliable and the battery life is very long. I recommend.

Reliable protection and easy integration
This TP-Link Tapo sensor is a must-have for smart home security. It’s compact, well-built, and very sensitive to moisture. I love that it integrates seamlessly with the rest of my Tapo ecosystem. The battery life is rated for a long time, and the app alerts are very reliable. It’s a small price to pay to avoid expensive water damage.

Very easy to setup
About 2 weeks after I installed them we had a tiny leak under the bathroom sink. I would never have known about it without these sensors, it was inside the cabinet under then sink. 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. Their software works well too. 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 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.

Stable Device on a Great Platform
This is likely the best water leak detector out there. tp-link/Tapo offer great platforms at no cost and their accessory products are always good. This detector is no different, although it requires a $25 hub for wifi connect. It's ok in my case because I use other Tapo hub devices. Tapo does say the hub greatly extends device battery life, so it's worth something if that's the case. Anyway, they connect quickly (I have 3) and test well. My only gripe is the high profile. I came from Phyn, which offered a hockey puck that could fit under things like a washing machine. But Tapo never disconnects like other brands do, and that's worth a ton.

Works well for my sensors I have for my apartment which I have a three windows and plus an entrance with a sensor on it and if you desire you could connect it to your data if you are technically inclined which I am not.. plus you can connect it to the cameras of your home but again I don't know how to do that..I'm a firm believer in this product..

The sensor itself is really useful and I have multiple T300 sensors. However this one was ordered from the US and it didn't work with my H200 hub because of different wireless frequencies used in the US vs. rest of world. Had to return the item.

I bought this item to be used as an IRextender so I could control some cordless lights that I use to light up artwork. The hub connected to my WiFi network without issue and I could get it to “learn” the devices IR remote control. However it only controls the device when it is within about 10 feet of it. I had two devices to control and could not find a suitable mounting spot that was close enough to control them both. My main goal was to add the hub to Apple Home on my iPads so I could create a scene and have all the art work aluminate at the same time. Even through I could add the hub to Apple Home and I could see the devices and functions nothing could be controlled from my iPad. It says in the setting that Matter on this device is in “beta” stage. Maybe that’s why it doesn’t work yet. I had no choice but to send it back.
