It offers instant app, SMS, and email alerts plus offline device-to-device control for local protection during outages. With up to 5 years of battery life per sensor and compatibility with Alexa, IFTTT, and Home Assistant, this scalable system safeguards your home or building from water damage with smart, reliable technology. ## Description Protect property from water damage with a long-range, plug-and-play leak detection system. Each kit pairs a YoLink Hub with multiple leak sensors you place near common risk points such as bathrooms, kitchens, laundry rooms, water heaters, and sump areas. When water is detected, you receive app, email, and SMS/text alerts so you can act fast. Built on LoRa, YoLink reaches where Wi-Fi struggles, with up to 1/4-mile open-air range. Unlike Wi-Fi-only systems, YoLink can act even without internet: with Control-D2D, sensors can directly trigger other YoLink devices—like sirens or motorized shutoff valves—for local protection during outages. Leak Sensor 1 is a silent sensor with no built-in siren; Leak Sensor 4 adds a built-in 105 dB audible alarm. Each sensor uses two AAA batteries and delivers up to five years of typical battery life. YoLink scales from homes to smart buildings. One hub supports 300+ YoLink sensors and devices, and hub options include the standard Hub, SpeakerHub for spoken alerts, and the Cellular Hub for flexible deployments. Manage everything in one app and expand within the YoLink ecosystem, with integrations for Alexa, IFTTT, and Home Assistant. Review: Peace of mind for wood floors! - Love this system! Easy to set up and connect the sensors. App works well. Detected a leak from our tub filler before it flooded the bathroom. I’m confident they work well and it gives me so much peace of mind having them with our house being 90% wood floors! Review: Peace of Mind! - As I mentioned in my valve controller review, as a child we had old water lines burst in our home, leading to massive damage. Ever since then I have been concerned with the same thing happening in my adult home. Finally, during a Prime Day sale I discovered the YOLink leak detection system. I combined this system with the Valve Controller to set up a smart system that will shut off my home's water if any leak is detected. That system starts here with the sensors and smart hub. I have placed a sensor under each sink and toilet fixture in my house. They also make "rope" sensors which are good to use around water heaters and under dishwashers and washing machines. They all work great. They were a breeze to configure with the smart hub. I tested each one and they all alerted as expected with a loud beep and messages to my phone. I will be purchasing more of these during the next Prime Day sale for use in my rental property as well. Highly recommend! ## Features - Complete plug-and-play kit: hub plus Leak Sensor 4 units, each with a built-in 105 dB audible alarm for instant on-site alerts. - Long-range LoRa: reliable coverage where Wi-Fi struggles (up to 1/4-mile open air); get app, email, and SMS/text alerts and name sensors by location. - Works even without internet: with YoLink Control-D2D, sensors can directly trigger YoLink sirens or shutoff valves for local protection during outages. - Low-maintenance power: each sensor uses 2 AAA batteries with up to 5 years typical battery life; easy replacement. - Scalable IoT platform: one hub supports 300+ YoLink devices; part of a whole smart home/building ecosystem; hub options include standard Hub, SpeakerHub, and Cellular Hub. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0DPH3KL69 | | Audible Noise | 105 Decibels | | Battery Description | AAA | | Battery description | AAA | | Best Sellers Rank | #62,595 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #407 in Safety Sensors & Detectors | | Brand | YoLink | | Built-In Media | Batteries | | Color | White | | Colour | White | | Compatible Devices | Over 300 devices | | Compatible devices | Over 300 devices | | Control Method | App | | Customer Reviews | 4.7 out of 5 stars 194 Reviews | | Item Dimensions L x W x H | 8.9L x 20.3W x 15.2H centimeters | | Manufacturer | YoSmart | | Maximum Range | 1000 Feet | | Mfr Part Number | YS1603+6YS7906 | | Model Number | YS1603+6YS7906 | | Number of Batteries | 12 AAA batteries required.

One recommendation for improvement. *by S***Y on 9 April 2026* YoLink got this design right. And I am not saying this lightly. I tried out a few different products and built my own Arduino-based versions. Yolink put together a small, unobtrusive device with exchangeable batteries (that upon my measurements so far are are likely to last years). It's straight forward to setup and possible to integrate into Home Assistant - and via the Homebridge into HomeKit. I would love to see that last integration available natively. Hint.. hint.. to the product design/requirements team. This is a cheap investment to avoid major water damage in your home. I got a few and located them in all the likely indoor leak places, under sinks, dish washer, washing machine, fridge/freezer. Strangely it was cheaper to buy a second set of six that include a hub than just an additional six - Alas, now I have a backup hub, in case the first one ever fails me :-) ## Frequently Bought Together - YoLink Smart Home Starter Kit: Hub & Water Leak Sensor 4 with 105dB Audio Alarm 6-Pack, SMS/Text, Email & Push Notifications, Freeze Warning, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT - Water Leak Sensor 4 with 105dB Audio Alarm 3-Pack, SMS/Text, Email & Push Notifications, Freeze Warning, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT, Hub Required! - YoLink 10 Foot Sensor Cable Water Leak Sensor 2 --- ## 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/774016186-water-leak-starter-kit-hub-6-leak-sensor-4-105](https://www.desertcart.be/products/774016186-water-leak-starter-kit-hub-6-leak-sensor-4-105) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-13*
