## Description

Protect your home from costly water damage with the YoLink Smart Home Leak Detection Starter Kit. This complete system includes a YoLink Hub and 4 water leak sensors, powered by advanced LoRa long-range wireless technology. With coverage up to ¼ mile in open air, YoLink outperforms WiFi or Bluetooth sensors, making it ideal for hard-to-reach areas like basements, garages, or sheds. When leaks are detected, you’ll get instant alerts via app push, SMS, or email—whether you’re at home or away. The kit integrates seamlessly with Alexa, IFTTT, Home Assistant, and more, letting you automate shutoff valves or alarms for proactive protection. Each sensor runs on 2 AAA batteries (included), with LoRa’s low-power design ensuring up to 5 years of service life. Installation is quick and easy: place sensors under sinks, near dishwashers, washing machines, water heaters, or sump pumps. Choose YoLink’s reliable leak detection system for always-on protection and total peace of mind.

Review: 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.
Review: Notifications are excellent and very accurate when detecting water

## 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.

1. The product description states "effortless installation" - placing the units is easy - but configuring the software installation is not. If you are at all phased by IT connectivity - try another system that is more easily installed. 2. This was delivered to the UK from the USA - so it came with a USA 2 pin plug.
