YoLink LoRa Smart Water Level Monitoring Sensor, Wireless Battery-Powered Float Switch Alarm, Sump Pump Alarm, AC Condensate Overflow, Tank Level, Toilet Leak Sensor, 105dB Siren, YoLink Hub Required

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.

Installed this around/under our washing machine. It was a bit difficult to hang the sensor and then string the cable in the tight space around the washer without moving it. The cable was long enough to run around the back of the washer where the water hoses are attached. It might be a good idea to get the add-on cable so we could extend it to the front of the washer as well. Overall, I'm happy with the YoLink system: easy to set up, attractive, effective, and reasonably priced.

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.

These sensors are a must have! They have quickly detected small leaks on two occasions before they got bad. We have had them for over three years and no false positives. So when they let you know there is a leak they mean it!

I like the design and easy of setup. The provided cord is too short, for every single one of my six sensors I had to purchase extension cords, shorter or longer ones at 10ft. So factor that into the cost. One of the sensors disconnected from the hub, even though being just underneath it in basement under wooden floor. It was not updating. Just alarmed that it was disconnected and before I could check on it it reconnected.

The rope is very sensitive and reusable. The range will be reduced by walls and other obstructions. A couple of my sensors are at their range limit at 400 feet through building walls and nestled beside equipment. Overall a well built product and great value. I now have 11 installed in my apartments and already one has help me respond quickly and avoid expensive damage repair.

This product is perfect for what I need. I have it in a sealed septic tank in the yard and it gives me piece of mind should my pump failed. I tested it after installing and it worked perfectly. Got an alarm to phone and email. It's nice that the base can sit in my house and plug into router because then I have extended Wifi for the sensor. The sensor is a little ways away from router but no connectivity issues at all. Very strong signal. I have had to contact product support for a question and they got back to me same day. Fantastic service.

I bought this to monitor the water level in my Christmas tree stand, and it’s been perfect for that. It alerts me when the water gets low so I can refill it before the tree dries out—no more needles all over the floor.Setup was easy, alerts are reliable, and the LoRa range works great even with the tree not near my router. For a non-traditional use case, it’s worked flawlessly. Simple solution that actually does what it’s supposed to do.

I purchased the hub and 4 sensors-great investment! There is no monitoring charge. The sensors run through the hub/base. I used water sensors for my sum pumps, floor drain and on floor to detect any water. Everything has been tested and works well. If any water is detected, the hub/base will beep, sensor will beep and my phone will notify me. This is excellent for peace of mind and also no monthly fees!

Useless,

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.
