Great product
water leak in the trunk of my car, parked outside up the driveway. Worked great, placed in the bottom of my trunk under the spare, alerts! Had to replace trunk gasket for it to stop. Also alerts when my internet is down.

Worth it : Yolink Temp, Humidity and Leak Sensors - A Detailed Review !
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 !

Water sensing sensors work great!
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.

Works, hard to set up.
This thing is kind of a pain to get set up. But it does work with the automation features with Alexa. Weโre using this on a dehumidifier that drains into a bucket.

It will certainly let you know when it detects water! Easy set-up and maintenance with the app on your phone.

Good insurance
Bought after a slow dishwasher leak created a huge mold problem. I tested the sensor in a small spill and it works. Hopefully will know about leaks before they become a problem in the future.
