With up to 2 years of battery life and compatibility with Alexa, Google, Siri, and IFTTT, it offers proactive, hands-free home protection against water damage. ## Description SwitchBot Water Leak Detector is a sensor that can help provide you with remote notifications to prevent water leakage in your home, no Hub needed. Features a waterproof shell, that can cope with high humidity environments. Meaning even when soaked in water, it can still send out notifications. Saves space and can be easily placed in smaller areas such as refrigerators and washing machines. Getting started is easy. Just install battery, long press for 2 seconds, and add to our app. With 2 x AAA batteries you can enjoy up to 2 years worth of battery life. How to test and verify SwitchBot App alerts and notifications? Ensure the SwitchBot App is updated, the Water Leak Detector is added with notifications enabled, Bluetooth is off, the device is submerged to trigger an alarm, and wait 30-120 seconds for Wi-Fi connection; if no alerts, check Wi-Fi or relogin. Why is there a delay in receiving alerts from the Water Leak Detector? To save battery, Wi-Fi only activates when water is detected, taking 30-120 seconds to connect. This delay is by design for power efficiency. Use a Hub near the detector for faster alerts. How to set up SwitchBot Water Leak Detector email notifications? Update the SwitchBot App, add the detector, then go to Profile > Preferences > Email Notifications > Important Device Notifications. Select your detector, enable "Email Alerts," and add your email.

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! ### ⭐⭐⭐⭐⭐ Works well, easy to set up to home system *by on Reviewed in the United States 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. ### ⭐⭐⭐⭐ Does Everything that is advertised. *by on Reviewed in the United States July 23, 2026* Works perfectly. Easy to set up. Would be five stars if you did not have to reset all the sensors if wi-fi goes down! ## Frequently Bought Together - SwitchBot WiFi Water Sensor 1 Pack, Smart Water Leak Detector, 100dB Adjustable Alerts & App Alerts, IP67 Waterproof, Wireless Detector for Kitchen, Bathroom, Basement, No Hub Required (Support 2.4G) - SwitchBot WiFi Water Leak Detector, Smart Water Sensor with 100dB Adjustable Alarm&App Alerts, IP67 Waterproof, Wireless Detector for Home with 3.28ft Sensing Cable, No Hub Required (Support 2.4G) - SwitchBot IP65 Indoor Outdoor Hygrometer Thermometer Wireless 3Packs, 394ft Bluetooth Range, Refrigerator Thermometer, Dewpoint/VPD/Absolute Humidity Sensor, 2-Year Battery Life, Free Data Storage --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/632476691-wifi-water-sensor-smart-water-leak-detector-100db-adjustable-alerts](https://www.desertcart.be/products/632476691-wifi-water-sensor-smart-water-leak-detector-100db-adjustable-alerts) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-15*
