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 ### ⭐⭐⭐⭐⭐ Quickly notified us of a leak, preventing a flood in our guesthouse *by on Reviewed in the United States 18 July 2026* Set up was super simple and the sensors work great. The Yolink notified me of a water leak in my guest house (by text) when the water heater failed and we were able to shut off the water main before any damage was done. Hub is in the main house, so I am impressed with the range of these sensors. Excellent value for the peace of mind these little devices provide. Great product! ### ⭐⭐⭐⭐⭐ Bueno *by on Reviewed in Mexico 19 April 2025* Buen invento ### ⭐⭐⭐⭐⭐ It Works Fast! Easy Setup and Good for Peace of Mind *by on Reviewed in the United States 29 July 2026* Within the first week, I heard beeping coming from under the kitchen sink, and low and behold, we had a small leak under our sink! It really gave me peace of mind that this will keep us from suffering a costly home repair, or major damage when we might be away from the house. I would recommend! Setup was super easy and took very little time. The beeping wasn't overly loud, but loud enough to hear from several rooms away, and the app will also send an alert. ## Frequently Bought Together - YoLink Smart Home Starter Kit: Hub & Water Leak Sensor 4 with 105dB Audio Alarm 4-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 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.be/products/723532561-smart-home-starter-kit-hub-and-water-leak-sensor-4](https://www.desertcart.be/products/723532561-smart-home-starter-kit-hub-and-water-leak-sensor-4) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-26*
