Great with the apo
The Tapo water leak sensor is a fantastic addition to any smart home setup. Itâs 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 damageâhighly recommend!

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!

Fantastic Leak Detector â Reliable & Easy to Use!
Iâve 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 issuesâsomething Iâve 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 Iâll know immediately if thereâs a leak. I also use Tapoâs 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.

Works well
Works well when testing. Hopefully will never have to be alerted by it for real. Notifications to phone come through quickly.

Great sensor to add
Does what it says. Great to add to the Tapo family. Easy to set up and it even tells you the battery level in the app..

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.
