Review: Excellent Leak Detection System — Reliable and Easy to Use - Excellent Leak Detection System — Reliable and Easy to Use I purchased the Hub + 4 Leak Sensors to monitor areas in my townhouse that are prone to moisture issues—under the HVAC unit, washer/dryer, refrigerator, and in the basement. After using them, I’m extremely impressed. Here’s what stood out: 👍 Easy Setup The installation was quick and straightforward. Each sensor paired with the hub without any trouble. 📱 Convenient Remote Monitoring The app makes it simple to check all sensors from anywhere, which gives me real peace of mind when I'm not home. 🚨 Accurate Alerts and Great Sound Quality The sensors react immediately to water. I had a real incident where my heating system’s pump failed on a very cold day. The device detected the leak instantly, and the app notification prompted me to call the HVAC technician before the situation worsened. Compact but Powerful The sensors are small enough to fit into tight spaces while still delivering strong performance. Their size makes placement very flexible. Overall, this has been a fantastic investment for protecting my home. Highly recommended for anyone looking for a reliable leak detection system.
Review: Simple, reliable, and worth It for the peace of mind - I bought this leak starter kit after dealing with a small leak under the sink that turned into a big cleanup job with a new cabinet...lol. I wanted something simple and reliable this time, and so far this system has been exactly that. Setup was super easy. I plugged the hub into my router, opened the app, and it basically did the rest. Each sensor paired with one button press. I had everything installed in maybe 10–15 minutes for entire house. What I like most is that these don’t depend on Wi-Fi. I’ve got one sensor tucked behind a toilet, another under the kitchen sink, and even one in a spot where my Wi-Fi normally dies... and every sensor still connects with no issues. I tested all four sensors with a damp paper towel, and they alerted instantly. I get notifications on my phone and email, which is great for when I’m not home. A big plus for me is the battery life. These use simple AAA batteries, but they’re supposed to last years, not months. And the app actually shows the battery level for each sensor, so you’re not guessing. It’s nice to know you won’t get blindsided by a dead sensor right when you need it. The sensors feel solid and the app is straightforward. Honestly, this setup has already given me more peace of mind than anything else I’ve tried.

## 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.

*by A***R on January 12, 2026*

This is a great product! RARELY, almost never, do I submit product reviews. However, I purchased the YoLink kit to monitor the home while I am away for an extended period. I received an alert on a water leak to my 2nd floor HVAC unit, and was able to quickly mitigate the issue. I just bought a second kit to monitor a second home. Simple, easy, and effective!
