SwitchBotWiFi 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 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.

They definitely work. I was awakened early this morning when I received an alarm on one of my 3 sump pumps. This failure was unexpected as I had had no prior problems with this particular pump. As far as I’m concerned these alarms just paid for themselves !

So far it works well. When I tested it the alarm sound was moderate, but the notifications were in real time. I didn't give it 5 stars because mine came without a user manual and the already installed batteries were low. The website does not offer a manual that I could print off or instructions. The app was slow and tedious when trying to add the device. I had a power outage a couple of weeks ago and my base flooded twice. Once after my secondary sump pump battery ran out then after my generator died. A leak detector that doesn't need AC power is critical for me.
