YoLink Water Leak Sensor 2 - 1/4 Mile World's Longest Range Smart Home Detector With Built-in Siren Up to 105dB, Compatible with Alexa and IFTTT - YoLink Hub Required, YS7904-UC

I've been a little paranoid about my sump pump recently. I have three pumps in my sump well, a primary pump with its built-in vertical float sensor, a secondary backup pump with a vertical float sensor positioned so that it will not activate unless the primary pump stops working, and a 12-volt pump that runs off a 100 amp-hour AGM battery kept charged using a battery tender. This 12-volt sump pump is my pump of last resort in case of a power outage, and its float will not activate unless the sump water level gets above both the primary and secondary pumps. With this setup, it's not easy to tell when my primary sump pump stops working. This YoLInk Water Leak Sensor 3 solves this problem. The sensor comes with a water sensor probe, which I did not use. For sump wells, they suggest that you use a float switch instead of the included probe since the probe terminals could become covered with mineral deposits and reduce their water detection sensitivity. I ordered the 'Level Sense 15 Feet Water Level Float Switch with Mounting Bracket' from Amazon and it works perfectly for this sump well application. I just had to wire in a standard 3.5mm male plug to the end of the float switch wires to be able to plug into the YoLInk Water Leak Sensor. The YoLink Water Leak Sensor requires the use of an inexpensive central hub (I bought the YoLInk SpeakerHub). It communicates with the hub by use of a long-range radio that has up to a 1/4 mile range and uses very little power. The two standard AA batteries in the Water Leak Sensor should last for one to two years. Setup was quick and easy. You just install the YoLink App onto your cell phone, plug in the hub anywhere in your house, and connect it to your home WiFi. Then you can easily add the Water Leak Sensor to your system by scanning the QR code on the sensor. The YoLink ecosystem has many different types of sensors, alarm speakers, switches, etc. for constructing very elaborate home automation systems. This Water Leak Sensor is a good introduction to this ecosystem, and I'll certainly be considering other home automation options. I attached the small Water Level Float Switch in my sump well so that it would not activate unless the sump water level rose above the normal maximum level permitted by my primary sump pump (but below the level where my secondary sump pump would activate). Now, if my primary sump pump stops working, I receive both an email alert as well as an app notification on my cell phone letting me know that the primary sump pump has stopped working. You can also set up the app to text you an alert, which I have not yet done since you are limited to 25 free SMS texts per month. Since the YoLInk system is compatible with Alexa, I also have all my Alexa devices announce that my primary sump pump has stopped working (easily done with an Alexa routine). In addition, I have set up my YoLInk system to notify me when the float switch opens back up, since this tells me that my secondary pump has run successfully, giving me peace of mind. The YoLInk Water Level Sensor is an elegant method by which to monitor my sump pumps. Now, no matter where I am, I'll know if my primary pump has failed and needs attention as well as whether my secondary backup pump has successfully run. I'm also impressed with the entire YoLInk ecosystem.

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.

They do not understand a word of English ,I feel I have been transported to a hawkers stall in my home country. I had to call call to get a refund Products are equally unreliable as the people behind it. Quick money

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 - Crawlspace 2) S2 - Crawlspace 3) Motion Sensor - Mailbox 4) Temp and Humidity - Crawlspace (to help monitor the duhimidifier) and Attic 5) 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.
