This rapid response capability can make all the difference in preventing water damage, giving peace of mind even when I’m away from home.

The build quality feels durable, and the device is designed to withstand prolonged exposure to damp environments. Smart Home Integration The Tapo Smart Water Leak Detector integrates well with other Tapo devices and is compatible with smart home ecosystems. This synergy makes it easy to incorporate into an existing setup, enabling automated actions like turning off smart plugs connected to appliances in the event of a leak.

A Great Addition to Smart Home Devices
I added the Tapo Leak/Water sensors to my Smart Home set-up after also adding the doorbell and hub as the hub/chime unit is required to provide the connectivity for the leak/water sensors. As with the doorbell, I chose TP-Link so that I didn't require yet another app on my phone. Once the hub was added to the app, the leak/water sensors were added really easily. I find the Tapo step by step guides really intuitive and these were added within 2 minutes. Their connectivity is reliable and they remain connected to the hub over a distance of 5-6m in my case. The units are nicely designed with the ability to detect water on a surface or dripping onto it from above. Overall I am glad I continued with TP-Link/Tapo products as these work well and operate in the background without any problems. At present, their battery life seems very good. I needed to contact TP-Link Technical Support regarding the doorbell I also purchased/set-up at the same time and the excellent customer focused response from Aurelia & Tyrone has made me super glad I expanded my Smart Home with Tapo. Great devices which work well together.

Great with the apo
The Tapo water leak sensor is a fantastic addition to any smart home setup. It’s compact, easy to install, and super responsive. I placed mine under the washing machine and kitchen sink, and it gives real peace of mind. As soon as it detects moisture, it sends an instant alert to my phone and sounds a loud alarm. Battery life is excellent, and it integrates smoothly with the Tapo app. A smart, simple way to prevent costly water damage—highly recommend!

Fantastic Leak Detector – Reliable & Easy to Use!
I’ve been using the TP-Link Tapo range for a while now, with over 10 different devices, and they never disappoint. This leak detector is no exception! Setup was incredibly easy, and it connected to my system instantly without any signal issues—something I’ve always loved about Tapo. Unlike my previous experience with SwitchBot, which had constant connection problems, Tapo has been 100% reliable. The app alerts are fast and clear, giving me peace of mind that I’ll know immediately if there’s a leak. I also use Tapo’s smart LED strip lights, motion sensors, and temperature sensors, and everything works seamlessly together. If you want a user-friendly, trustworthy smart home brand, Tapo is the way to go! Highly recommend this leak detector.

Great for peace of mind - brilliant App
Am a great fan of Tapo , have five of their camaras, 18 of their plugs , load of bulbs and just recently 6 of their thermometers . I just recently had my boiler replaced and wanted to check that my old pipes would survive the added pressure . These leak detectors are really well made , quite heavy , a really good size and easy to set up and have contacts on the top as well as their bases ,For some thing so small the alarm is loud . I hope the battery life's good as i have put them under floor boards and behind washers and the tumble dryer .

A really useful tool
I have a mystery leak that occurs from time to time so I got this sensor. I place it in a container to also record the amount of water that has leaked. It has two leak detection areas. The top sensor is less reliable as drips need to land directly on the sensor area which is a small target and can be missed! The sensor's base probes are more reliable especially if placed in a container as it becomes more likely the probes will detect the water. Once a leak is detected, the leak needs to be cleared, the sensor dried with a towel and then its good to go again. Unfortunately the app's leak log can't be edited or notes added so it wasn't very useful for an intermittent leak. This aspect of the app could be improved. My upsum is it was a good purchase given the hub is a reasonable price and has helped me greatly understand the times of the mystery leak!

Good smart home addition
This is an item that's very easy to use as long as you have the relevant Tapo hub for setup and monitoring/alerts. I found the alarm/noise level when notifying you of a leak more than adequate

Already saved a leak
As usual with Tapo, a quality product at a good price. Fitted it to help resolve a persistent leaking WC. Detected the small leak and helped me locate the source. Saved a lot of potential damage. Alarm works perfectly with Tapo app and hub.
