## Description

SwitchBot WiFi Water Leak Detector for Home, Water Leak Sensor, 1m Cable | No Hub, 100dB Water Alarm, App & Email Alerts, IP67 Waterproof, detects leaks/drips/water levels, 2.4GHz, 2-year battery life - desertcart.com

Review: Works great - I had purchased the water sensor with the long sensor cord for my sump pump. I wanted to get alerts as the water was rising but before it spilled out onto the floor. The sensor having a long cord allowed me to do this. Most sensors have to have contact with the water on the sensor body in order to get an alert. I was also searching for a product that gave push notifications without a monthly subscription fee. The switch bot leak detector accomplished this. So far has been a great/ reasonably priced product. The setup was also very simple. Thanks!
Review: Worked exactly as advertised - Worked exactly as advertised. Since my HVAC unit is located inside my apartment, I decided to place one of these devices underneath it for added protection. The setup process was quick and easy, and the device supports Wi-Fi connectivity as well. After testing it, I received all notifications promptly and without any issues. Overall, it performs reliably and provides great peace of mind. Highly recommended!

## 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 Only)
- 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.
- Water Level Detection: Equipped with a 1-meter extended probe, you'll be able to detect changes in water levels of places like swimming pools, bathtubs, and fish tanks. It can also be placed in narrower areas, such as inside refrigerators or washing machines. And is suitable for homes, warehouses, basements, sinks, water heaters, pipelines, and more.
- 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.

### ⭐⭐⭐⭐ Would recommend
*by B***. on July 2, 2026*

I am not a techy and was able to set these up with relative ease. They are excellent at detecting water immediately. the problem is getting alerts (not alarms, but texts and emails) either because they have gone off-line or some other reason which I can’t explain. I like that they come with or without a cord that can get tucked in somewhere where the device itself cannot reach. despite the alerts mentioned, I am so happy with them because they bring peace of mind
