Water Leak Starter Kit: Hub + 2 Leak Sensor 1 (Silent), LoRa Long-Range, App/SMS/Email Alerts, D2D Offline Triggers, 2 AAA Up to 5-Year Battery, Compatible with Alexa/IFTTT/Home Assistant

Very easy to set up/pair. I tested each one in a pan with water in it & they notified me right away. I have one by the boiler & the other by the water softener. Good insurance & peace of mind.

Was easy to setup and connect with app. Had purchased another brand previously that was difficult but this one so far has been very good.

Worth it : A bit pricey compared to others, and needs a cheap, small hub to operate, but Yolink is definitely worth the price, if accuracy is your goal. Leak sensors work perfectly. But bought this ecosystem more for their temp + humidity sensors. App comes with the ability to set exact temp and humidity alarms, which can be sent via App Notice, SMS Message (75 Free SMS Alerts Per Month) and/or Email Alerts, all of which are infinitely customizable. Setup is super quick, once you figure out how to scan the barcodes on each device with the App. Hub setup took 5 mins tops. Extremely long range, about 1-3km in urban areas. ProTip : Once temp sensors are setup. allow at least a few hours for them to stabilize. Sensor are very accurate. Six temp + humidity sensors all showed the exact same reading within 0.01% after six hours sitting next to each other, and App also allowed each sensor to be adjusted if needed. Highly recommended !

It was easy to connect to wifi. I tested the sensors and the app notified me as expected. I have not tested the email, sms or siren function so only can give it 4 stars.

Got this because we were going to be away from the house for a bit, and we were concerned that the bathroom that we were remodeling with pipes exposed and might spring a leak while we were gone. The leak sensor worked like a charm and gave me peace of mind. Was thinking of getting another couple of sensors to put throughout the old house.

I’ve been really impressed with my YoLink water leak sensor. It’s been rock‑solid with no false alarms, and it actually notified me when my internet went down — something I didn’t even expect it to do, but now I’m glad it does. The whole system feels dependable and thoughtfully designed. If you want a leak detector you can trust without constant babysitting, this one delivers.

So simple! I previously had Samsung SmartThings water leak sensors (with a SmartThings hub), but Samsung doesn't make these any more. Apparently Aeotec now produces the Samsung sensors, but they're $40 each! I needed a sensor in an attic that was hard to access, so I wanted a device that had a really long battery life. I wasn't excited to have an additional "hub", but the YoLink LoRa technology is completely different and isn't compatible with Samsung SmartThings. Regardless, I went ahead and tried the YoLink hub/water sensor and was very impressed. The hub set up extremely quick and the devices paired immediately. I love that the app can set up multiple alerts (iPhone notification + SMS text + email), which is exactly what I wanted. I would definitely recommend this system!

Reliable leak detector without the loud alarm. Connect to your local internet, place in area, forget. Install app forget. Leak detected phone notifies you. Super easy and love it. Love it. I've used loud alarm ones before and that works if you're there or can hear it. If you're not there you can't turn the loud alarm ones off so it annoys the neighbors or you miss the leak then it defeats the purpose. I love this yolink one because it digitally notifies you if there is a link. It's great if you're a way form work or out of town and it says leak detected. This is exceptionally helpful. These have a 5 yr battery life supposably so you do not have to replace them every couple of years like others. I'd rather invest into a sensor than have thousands of dollars of water damage.
