This sensor, that can work by itself or also works along with the YoLink suite of sensors is unique in that it uses a cloth like braided material surrounding a long sensor element that when the second it gets wet sounds an audible alarm and if you have it configured with their app it will send you text and / or email alerts every 5 minutes or so. You can place it around the bottom of a water heater or sink cabinet or A/C pan to cover a larger area so a leak can be detected as early as possible. If you need to cover a larger area you can link more sensor cables together, although I have not tried this or have not seen where you buy extra lengths of sensor cable.Of course, I did test the sensor and it reacts to even a drop of water and once the sensor cable gets wet is will alarm for quite a while even if you have tried to dry it with a towel. So I thought since this was just a test that I would just unplug the sensor cable and wait for it to dry out,,,, at which point, it started sending me texts every five minutes that the sensor cable was unplugged. Now while annoying, I thought that was pretty genius on the designers part since you would really like to know if the sensor had become unplugged (Think, for example, if you had moved some items underneath a sink and it pulled it out), well the sensor would no longer be viable but you wouldn't know until the water was running across the floor. Not with this little device as it will send you a notification.I have only had the system in place for two months (they also have other sensors available) and the battery levels are all still indicating full so I have not seen how well that feature works as it is supposed to track the battery level of the sensors. ( not sure if it sends an alert about low battery level)All in all, this is a slick set of sensors and while the app is a little bit clunky to get everything named and organized, once it is setup it is transparent. I hope this company can stay around to help support their product and possibly add other sensors to their repertoire.

Another addition to my YoLink System. Connected to the hub without issue and tested the cable to moisture exposure. It activates warning immediately. However, moisture needs to dry out on cable, before it is fully functional again. Knowing this I bought a secondary cable to use as well. Great system, great purchase.

I almost never write reviews here but I have to say this device has performed in excellent fashion. I have one thermometer and two leak detectors and just purchased a third. The connection (range is amazing) and functionality has been outstanding.

I do not often write reviews, but the YoLink sensors have been a great addition.Today, 12/3/2023, I was out and about. I received a notification on my phone that a leak was detected in the crawlspace. When I got home and went into the crawlspace I found water in the reported location (I use a naming convention so I know the type and location of the sensors).The leak was a slow drip and the water had pooled. Once the "tail" of the S2 sensor was wet I received the alert. This was a very slow leak and it took some time for the water to build up to touch the "tail". Sometimes it is hard to get the tail to lay perfectly flat. I try to place them in lower areas too. Perhaps if a simple change like rolling the "tail" sensor vs folding them would help, but I really can't complain. They are easy enough to straighten out.I mean how many times to do go into the crawlspace in a give year. A handful? So these play an important role in being proactive.I have looked at other sensors that are cheaper, but I do like the ecosystem and they are very reliable.I have water sensors (S1's and S2's) at key points in the crawlspace to detect this very thing. The battery life is amazing. They have been deployed for over a year and they still report having full batteries. It would have take a long time for us to know that we had a slow leak. That is if we found it in the first place. Like I said before we do not often go into the crawlspace or attic. So for what is worth these add value.I do wish they were priced a bit lower though.In my case I have Yo-Link sensors in the following areas:1) S1 - Crawlspace2) S2 - Crawlspace3) Motion Sensor - Mailbox4) Temp and Humidity - Crawlspace (to help monitor the duhimidifier) and Attic5) Outdoor Power Outlet - This allows for the remote control of the pump in the water feature (schedule control). Last year the water froze and part of the feature broke and had to be replaced. So I got this and am able to change the schedule when it is going to freeze. On the second plug I put an aquarium water heater stick that I can turn on to help keeping the water to freeze. The combination was way cheaper than other options.6) Vibration Sensor (available on the YoLink site) - I am going to buy one of these to put on the dehumidifier in the crawlspace. We had an error that we did not notice for about two weeks. This can trigger an alert in the absence of any vibration. I am going to give this a shot too once I save some money.

Would be 5 star but loses 1 star for no way to stop the sensor from triggering except unplugging the cable. I got this sensor to monitor our sump hole, ours is a gravity drain but sometimes bad winter storms drift snow in front of the drain & cause ice plugs. We have a pump on a timer to drain it but with the spring thaw coming I worried we might get a backup, so I got this sensor. I just tested it, the cord itself, NOT the jack at the end of the cord, is what needs to get wet to set of the alert, only problem is that it won’t stop triggering until the cord is dry so it has to be unplugged from the sensor unit until it dries out. This alone should mean 2 cords should be provided with original purchase so they can be swapped out. Now I have to purchase a separate back up cord. Other than that it works like a charm. I have several Yolink devices now, I love that I can purchase devices individually as I need them to expand my smart home network.

Yolink is an awesome smart home product that I have bought lots of. Works when wifi goes out, uses hardly any battery power and never have false alerts. Will be buying more Yolink products in the future as I build my smart home. You can trust this product.

This is only one of the line of YoLink products that we purchased and all of them are very reliable, easy to operate and recommended!This one I'm using as alert for sump pump. Hi availability, long range coverage and reliability. Various scenarios can be programmed and alarms will be received. Shareable monitoring.

Nice and neat to have in the house for early notifications of water leaking
