YoLink Water Leak Starter Kit: Hub + 6 Leak Sensor 4 (105 dB Siren), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

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!

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!

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 :-)

Perfect solution for detecting leaks around the house. Does what it says, fairly easy setup to home wifi. I like the customizable alerts. Great price for 6 sensors.

After two sump pump failures, my nephew recommended this brand. I wanted something that would sound an alarm as well as send an alert to my phone. I like that this will sense water from above as well as below. Each sensor is able to be named. I did have to hook the hub directly to my modem, but it works great. Each sink has a sensor, plus my main water shut off, the sump pump and my water heater. So this package was the best option for my house. One caution, the app needs to be set not to go into deep sleep on the phone.
