But you need to understand how they work 1) They only work over bluetooth. This is good, keeps the battery life long 2) You need some whole house bluetooth receivers. If you happen to have shelly devices with the bluetooth capability (Like the plus series) then you're all set. Because Home Assistant can configure the shelly switches to listen and pickup bluetooth signals from all over the house. If you have these things, then setup is easy. Pop the included AAA batteries in, check Home Assistant and it will say it detected a Switchbot Leak Detector. Click "Yes, set it up" and you're done (but give it a better name). Shows up with the proper icon (water drop) and type (moisture). Now the real fun is the automation. I have a zwave whole house water shutoff device. It will turn the quarter turn valve on my incoming water line to my house. I grouped all my leak detectors and created an automation that says "If the group (IE any one of the group) detects water then shut off the whole house water valve". Tested it out and within 1-2 seconds of a water drop the valve is turning off. It also sends me a notification too. The sensors themselves are very sensitive. The top is dished a little so if a single drop of water hits the top it will likely set it off. The bottom contacts are pretty sensitive too but would take a very small puddle just due to how the sensor is on the bottom and water spreads. They do have an alarm too, it's not super loud, but it will get your attention if you're in the same room. Mostly though I bought them for the Home Assistant integration. There are cheaper sensors if you just want an alarm when water hits them. Water damage is the worst thing for a house, and also the most likely. Toilets, sinks, washing machine, water heater, anything with water should have a sensor next to it and ideally some automation to cut the water. In 20 years of home ownership I've only had 2 major issues and both were water related (water heater once, washing machine second). I'm all prepared to never have another one (fingers crossed!) I have 12 of these spread out around my house. Review: Water warning system - Great product! Use it as water leak protection warning system for my tankless water heater! Easy to setup and install! ## Features - No Hub Required：Direct WiFi Alerts. Get instant leak alerts via app & email without any hub —just connect to 2.4GHz WiFi for real-time remote monitoring . Share access with family for 24/7 home protection from leaks, floods, or pipe bursts. (BLE backup ensures reliability even if WiFi drops). - Ultra-Sensitive 0.5mm Detection：4 high-precision probes detect micro-leaks (as low as 0.5mm ) before major damage occurs. Place near water heaters, sinks, dishwashers , or basement sump pumps —compact design fits anywhere. - 100dB Alarm + Smart Mute：Ear-piercing 100dB siren alerts you even in distant rooms (like basements). Manually silence alarms via app after resolving leaks, no annoying false alerts . - 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 with Alexa/Google/Siri：Voice-control via Alexa/Google/Siri or automate responses with IFTTT/SmartThings. Pair with SwitchBot Plug Mini to cut power to leaky appliances automatically. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CRRL9DNN | | Audible Noise | 100 Decibels | | Battery Description | Alkaline | | Best Sellers Rank | #24,579 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #26 in Water Detectors & Alarms | | Brand | SwitchBot | | Built-In Media | SwitchBot Water Leak Detector | | Color | White | | Compatible Devices | Washing Machine | | Control Method | App | | Customer Reviews | 4.6 4.6 out of 5 stars (1,406) | | Item Dimensions L x W x H | 2.6"L x 0.7"W x 5.5"H | | Item Type Name | Water Leak Detector | | Item Weight | 68 Grams | | Manufacturer | Wonderlabs | | Maximum Range | 120 Meters | | Mounting Type | Floor Mount | | Number of Batteries | 2 AAA batteries required.

This delay is by design for power efficiency. Use a Hub near the detector for faster alerts. **Q: How to set up SwitchBot Water Leak Detector email notifications?** A: 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.

Easy to setup and install! ### ⭐⭐⭐⭐ Good, but here is how it could be better *by N***Y on August 27, 2025* These little things work very well...they go off with even the slightest bit of water . the alarm is a decent level of loud depending on the size of your home and where its located. I have them near toilets and near my water heater, laundry. Under sinks. where there are high pressure water lines. I wish they could link to a wifi/or direct device to device connection to an emergency shut off valve. thats my only issue with it...(unless im missing something) but letting you know you have a leak is cool, shutting the water off at the main is Great!! becuz after it tells you there is a leak...if you are not home, OMG, u will freak out and then have to get home...so having it be able to link to a emergency auto shut off valve would complete the circle . they should make one , then this system would be Amazing ## 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.tw/products/632476691-wifi-water-sensor-smart-water-leak-detector-100db-adjustable-alerts](https://www.desertcart.tw/products/632476691-wifi-water-sensor-smart-water-leak-detector-100db-adjustable-alerts) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-23*
