It offers instant app, SMS, and email alerts, plus offline device-to-device triggers that activate sirens or shutoff valves even during internet or power outages. Compatible with Alexa, IFTTT, and Home Assistant, this scalable system runs on long-lasting AAA batteries (up to 5 years) and provides professional-grade protection for hard-to-monitor areas like basements, attics, and utility rooms. ## Description Complete plug-and-play kit: hub plus Leak Sensor 1 units for whole-home coverage at toilets, sinks, water heaters, laundry, dishwashers, and sump areas. 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. Silent design: Leak Sensor 1 has no built-in siren; add SpeakerHub or a YoLink siren for audible or spoken alerts if desired. 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. Review: Peace of mind, delivered — from anywhere in the world - Water damage is one of those home disasters you don't think about until it's too late. The YoLink Water Leak Starter Kit changed that calculus for me completely — and the relief it provides is hard to overstate. Setup was remarkably straightforward. Getting the hub and four sensors up and running required minimal effort, which matters when you're dealing with hardware that's going behind appliances and under sinks. No wrestling with complicated configurations or cryptic instructions. The real magic is what happens once it's all running. If a sensor detects a leak, it automatically triggers the main water shutoff — no intervention needed, no frantic rush home, no crossed fingers. That automatic response alone is worth the price of admission. But on top of that, I can shut off my main water supply manually from anywhere, whether I'm at the office, on vacation, or just away for the weekend. That kind of remote control over something as critical as your water supply is genuinely reassuring. The LoRa long-range connectivity means the sensors stay reliably connected even in spots where other wireless devices might struggle — basements, utility rooms, far corners of the house. And the Alexa integration works seamlessly, adding another convenient way to interact with the system without reaching for your phone. If you're a homeowner who wants to stop worrying about what might be happening to your house while you're away, this kit is a no-brainer. It's practical, it's reliable, and it delivers exactly what it promises. Absolutely worth every penny. Review: works great - I’ve been very impressed with this Wi-Fi water valve system. It connects seamlessly to my phone and allows me to remotely open or close the main water supply to my house, which adds a great level of convenience and control. I paired it with a compatible water leak sensor to create a smart leak detection system. I also integrated everything with Alexa, so if a leak is detected, Alexa immediately announces an alarm both in my home and on my phone. At the same time, the system is set up so the valve automatically shuts off the water supply—even if Wi-Fi or power is down—which gives me extra peace of mind. I’ve only been using it for a few months, so I can’t yet speak to the long-term battery life of the sensors. The valve itself is connected to a 110V power source but includes a backup battery to operate during power outages, which is a great feature. Overall, I feel much more comfortable knowing my home is protected against potential water leaks. It’s a smart investment for anyone looking to prevent costly water damage ## Features - Complete plug-and-play kit: hub plus Leak Sensor 1 units for whole-home coverage at toilets, sinks, water heaters, laundry, dishwashers, and sump areas. - 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. - Silent design: Leak Sensor 1 has no built-in siren; add SpeakerHub or a YoLink siren for audible or spoken alerts if desired. - 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 | B084WYB8PM | | Battery Cell Type | Alkaline | | Best Sellers Rank | #3,060 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2 in Water Detectors & Alarms | | Brand | YoLink | | Built-In Media | Batteries | | Color | White | | Compatible Devices | Smartphone | | Control Method | App | | Customer Reviews | 4.6 out of 5 stars 6,708 Reviews | | Item Dimensions | 8 x 2 x 4 inches | | Item dimensions L x W x H | 8 x 2 x 4 inches | | Manufacturer | YoSmart | | Maximum Range | 1320 Feet | | Mfr Part Number | YS1603+4YS7903 | | Model Number | YS1603+4YS7903 | | Power Source | Battery Powered | | Sensor Technology | Contact Sensor | | Smart Home Compatibility | Smart Home Compatible | | UPC | 850024791565 | | Unit Count | 1 Count | | Voltage | 3 Volts | ## Product Details - **Brand:** YoLink - **Color:** White - **Compatible Devices:** Smartphone - **Power Source:** Battery Powered - **Product Dimensions:** 4.33"L x 4.33"W x 1.06"H ## Images ![Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant - Image 1](https://m.media-amazon.com/images/I/61wxSqXRbDL.jpg) ![Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant - Image 2](https://m.media-amazon.com/images/I/71WmbaoJPWL.jpg) ![Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant - Image 3](https://m.media-amazon.com/images/I/71axvXpuqUL.jpg) ![Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant - Image 4](https://m.media-amazon.com/images/I/61QtUAdBCYL.jpg) ![Water Leak Starter Kit: Hub + 4 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant - Image 5](https://m.media-amazon.com/images/I/61d-5S9TiEL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: What are the dimensions of the water sensors? (Inches and centimeters)** A: The dimension of YoLink Wate Leak Sensor is 2.44*2.44*0.93inches (62*62*23.5mm), the package dimension is 2.48*2.48*1.02inches (63*63*26mm). **Q: How to make with Alexa? Using a routine?** A: Yes, use a routine to enable the voice alert from Alexa for YoLink leak sensor. Please refer the video: https://www.youtube.com/watch?v=gr9MpQi2Vwo Thanks! John from YoSmart Team **Q: I don't see any rope sensors which is bad for covering areas like washers, fridge, and water heaters. Any rope solutions I'm unaware of with this?** A: There are 3 ways to connect the extension cable to YoLink Leak Sensor. 1. Soldering with a soldering iron: (1) Use a soldering iron to solder 2 common wires (regardless of positive or negative) to a set of probes on the Leak Sensor (a set of probes on the top of the leak sensor is recommended) (2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly ) (3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm) But please kindly note: If you use a soldering iron to solder the wire, it may damage the two probes of the original device, which may cause the probes to rust in a humid environment. 2. Use glue or tape to fix (1) Use glue or tape to stick 2 ordinary wires (regardless of positive or negative) to a set of probes on the leak sensor (a set of probes on the top of the leak sensor is recommended) a. Stick the wire to the end of the probe and roll it into a circle or ring to expand the contact area & assist in fixing; b. It is recommended to use glue/tape with high viscosity, which must be firmly adhered to! (2) Fix the leak sensor in one place (If you use double-sided tape to paste the bottom of the leak sensor to the wall, the thickness of the double-sided tape must be higher than the height of the footpad on the bottom of the leak sensor (>1.5mm), otherwise, the leak sensor may not stick firmly) (3) Place the 2 wires in the area to be detected. The 2 wires must be separated and fixed with a certain distance (10~15mm) But please kindly note: If the glue/adhesive tape fails to stick the wire firmly, it may cause the wire to fall off and the leak sensor may not work properly. 3. Use the Alligator Clip We have found a way to use the Alligator Clip to clamp securely connecting the probes of the leak sensor and the extension cables, please visit the following video for instruction, https://youtu.be/x-bBXegLUcc Please wrap the leak sensor and the clip with tape to prevent it from falling off. As for the clip, you will find it on Amazon https://www.amazon.com/dp/B0739YWFQ6 I hope that will be helpful to you. Any question, please kindly contact us, thanks! **Q: Can one person with the same email address and phone number hold multiple accounts, ie. a building manager for a condo?** A: Sorry, one email address can be associated with only one YoLink APP account, and one phone number can also be associated with only one YoLink APP account. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Peace of mind, delivered — from anywhere in the world *by W***Y on March 31, 2026* Water damage is one of those home disasters you don't think about until it's too late.

So far it has worked very well. The biggest benefit is peace of mind. These are areas we do not check every day, so having reliable alerts makes a big difference. Setup was straightforward, the sensors connected without much trouble, and the system has been stable. Notifications have been timely, which is exactly what we wanted. If you need monitoring for places like an attic, utility area, or basement where early warning matters, this system is a great choice. ## Frequently Bought Together - YoLink Smart Home Starter Kit: Hub & Water Leak Sensor 4-Pack, SMS/Text, Email & Push Notifications, LoRa Up to 1/4 Mile Open-Air Range, w/Alexa, IFTTT, Home Assistant - YoLink Water Leak Sensor 3-Pack, LoRa Up to 1/4 Mile Open-Air Range Smart Water Leak & Flood Detector, SMS/Text, Email & Push Notifications, w/Alexa, IFTTT, Home Assistant - YoLink Hub Required - YoLink Smart Wireless Temperature & Humidity Sensor, Wide Temp Range for Fridge, Green House, Pet Cage, App Alerts, Emails, Text/SMS alerts- Hub Required --- ## 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.us/products/198287815-water-leak-starter-kit-hub-4-leak-sensor-1-silent](https://www.desertcart.us/products/198287815-water-leak-starter-kit-hub-4-leak-sensor-1-silent) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-04*
