SwitchBot WiFi Water Leak Detector, Smart Water Sensor with 100dB Adjustable Alarm&App Alerts, IP67 Waterproof, Detector for Home with Cable, No Hub Required (Support 2.4G) (White, Pack, 1)

The sensor works perfectly and is very sensitive. I have a water heater in my attic that's sitting on an overflow pan. For some reason, it started leaking randomly and overflowed the pan, causing water to leak through the ceiling. What a nightmare. I got this sensor and it alerted me after another leak. It allowed me to immediately go up and check it out. I located the issue, fixed it and the pan didn't overflow this time. It went off one more time after a small droplet tripped the sensor, so it's very sensitive, which is good. Overall, I'm extremely happy with it and it's way better than anything else on the market.

I recently bought a 3 pack of the water leak detectors. I placed them in my basement to track down where water was coming from and when it appeared so I could promptly dry it. They have worked well so far and have alerted me to a few times that water has appeared. The audible alarm, push notification and email have all been helpful.

works good .. a little hard to follow with the QR code and putting in code manually. so trial and error until I got them installed.

Test OK. Just need to install the phone APP SwitchBot with this device so you can monitor the water leak incidents remotely. The device needs a reliable WIFI 2.4GHz internet access (like IOT) to work independently without the need of a hub. For the remote location detection, the buzz siren can be turned off and the warning notification can be shown on the cell phone as well as via email.

Seems to work perfect when tested, got them in my basement & garage, for $20 will be worth every penny for a heads up the next time a potential problem pops up.App alerts on iPhone at home or away is just what I was looking for

Seems to be a good value. The first night the round sensor that I had stuck to the pipe in my sump fell into the water and went off. It was 1:30 am so I was glad to see that it just fell but assured me that it does work.

I’d rate these devices at 3.5 stars. I purchased three for our business to monitor water exposure near critical network infrastructure, as recommended in a recent risk assessment.The build quality is decent, though one of the battery compartments didn’t seal properly. Each sensor connects to the main unit via a cord, which I mounted on the wall away from water sources. The audible alarm is disappointingly quiet—you won’t hear it from outside of the room they're in if there's any ambient noise. These are installed in equipment rooms that have constant noise from fans and running network hardware. However, I rely on email and text alerts, which work as intended.Connectivity-wise, one device struggled to connect to Wi-Fi but eventually stabilized. The app is simple to use, and alerts function reliably. After over a month, they’ve performed as expected during testing, though I haven’t had an actual need for them yet.

My basement in my 90 year old house leaks. This device worked perfectly to let me know when the water is encroaching my household goods so awesome.
