Review: Great little detectors! - I am very pleased with the switchbot detectors. I purchased them because I had an unknown long term leak from my dishwasher that caused about $15k in damage to my home. After the repairs, I needed some peace of mind. The detectors are small and seem to have great battery life. Getting them set up on my Wi-Fi network was simple and I like having the ability to get email alerts in addition to the audible alarm and push notifications from the app. I feel much better knowing that if I have a future leak I will know about it before it causes lots of damage.
Review: This is a no-brainer! - The SwitchBot WiFi Water Sensor is one of those devices you hope you never need—but you’ll be really glad you have it. Setup is quick, especially if you're already in the SwitchBot ecosystem. It connects over Wi-Fi or Bluetooth, so there’s no separate hub necessary to fuss with, and alerts hit your phone fast when water is detected. I would encourage anyone to connect it to their existing hub if possible. Switchbot has a lot of them (some even built into other smart devices) and I have mine included with not only Switchbot's hub but my Homey Pro. The sensor itself is small and easy to tuck under sinks, behind toilets, near water heaters, or by washing machines. Sensitivity is good—it can catch even small leaks before they turn into expensive disasters. The app notifications are loud and clear, and you can also tie it into automations (like turning off smart plugs or triggering other devices). Mine is under my kitchen sink where I've already had an issue and was kicking myself for not already having this device. Trust me it's very inexpensive for peace of mind!

## Features

- Real-Time Notifications (No Hub Needed): After connecting to Wi-Fi, you will be able to receive real-time email and app notifications remotely when dripping, leaking, or flooding is detected, without the need to purchase an additional hub. Share devices with family, and they can also check home status at any time. (2.4Ghz Wi-fi & BLE).
- High Sensitivity Drip Alarms: This Device is equipped with four sensor probes at the top and bottom, which can detect a low water level of just 0.5mm. If water pipes drip, and your floor is submerged, or gets wet, it will sound an alarm. Water Leak Detector is compact and convenient in size, suitable for placement in laundry rooms, water heaters, dishwashers, sinks, and other places.
- Includes Loud Alarm Sounds: To help you stay alert, We've included 100dB high pitched alarms, which means even if there is a leak in basements or places a little further away, you'll know in a timely manner. Once Discovered, you can manually set it back to mute without worrying about noise issues.
- IP67 Waterproof & Up to 2 Years Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments. It comes with 2 x AAA batteries and has a battery lifespan of up to 2 Years. When Battery is low, our app will also send notifications to remind you to replace them in a timely manner.

### ⭐⭐⭐⭐⭐ Works well, easy to set up to home system
*by S***M on May 30, 2026*

These come with very easy to read instructions. (Written by an English speaking writer). The directions are clear, concise and the monitors are easy to set up and test. They come with batteries. I tested with a semi-damp paper towel prior to putting them in their final position and they alarmed (you can control the loudness - most other sensors you cannot) and sent an alert to my phone. They can sense if the liquid is coming from under the sensor or dripping on top of the sensor. I am very pleased with this product. As side note, you can purchase separately a device that can turn off the water in your house. I may get that at a later time.
