YoLink Smart Home Starter Kit: Hub and Water Leak Sensor, 6 Pack, SMS/Text, E-Mail and Push Notifications, Lora Up to 1/4 Mile Outdoor Range with Alexa

After a refrigerator ice valve cracked and slow-dripped its way to a $55k hardwood floor redo, I wanted a water alarm system for every plumbing point in our home. This system was well-reviewed, and importantly will allow me to eventually upgrade to an automatic water main shut-off valve in the near future. Super expandable, small footprint, well-constructed with an easy to use app showing each sensors status and remaining battery life; brings me much-needed peace of mind. I especially like the string sensors for under the dishwasher and refrigerator as they cover a large area for potential leaks, but wish there was a way to shut off their built-in audio alarms without having to pull the sensor out to dry it. The standard sensors don't seem to have the audio.

So far so good. I got these sensors as a kit to put underneath my water sources, such as the kitchen sink and underneath the toilet and the sinks in our bathrooms. I still need to get one or two more to put near the clothes washer and underneath the dishwasher. But it’s a good start. I also sent my receipts to my insurance company and they gave me a small discount, but I was hoping for something a little bit better as far as a discount goes. The app that yelling provides has a section for turning on a response to shut off your water meter which I also have in response to a leak. However, I can’t figure out how much to put in there as far as water loss over a period of time because if you have a complete pipe break, it’s a lot of water to mark as lost before the thing will shut off. So you could still have damage, but I have a good amount of water usage when we run the wash washer and things like that so it’s kind of hard to figure out where to configure the app for that aside from normal usage. That’s why I got these sensors. And I have these tied into home assistance so if the sensor is detect a leak for an extended period of time then they will end up alerting home assistant, and then I can use that to shut off the water. My wife was reaching under her bathroom sink for something and I think she had wet hands because that sensor alerted once and two or three months and didn’t alert anymore after that one time. So I know they work and I also tested them out with a couple drops of water Across the censor probes anyway. I like the fact that the sensors have electrodes on both sides so they will be able to pick up anything dripping or anything standing. I also like the fact that these use a standard AA or AAA battery so that should be easy to replace after they get low, but I’m also monitoring the battery level with home assistant as well.

I have so much more peace of mind knowing I have these installed! They were very easy to install.. I also had to work with a casita that is farther away from the router and I managed to hook up everything I needed. I tested a few of the sensors and they worked as expected. I also needed to contact customer service for a question on the install and they promptly responded with information for me. The sensors are small in inconspicuous.. Great purchase!

Works exactly as advertised. Saved our basement more than once

These leak detectors are elegantly designed with smooth and simple lines - it’s almost a shame that most of them are inside cabinets under the sink sinks. We tested them a bunch of different ways with water on top and underneath and tiny bits of water and more water – flying colors all around. The app is also easy to use. The whole thing was easy to set up.
