## Description

Product Requirements: The smartphone or tablet able to run iOS 9 or higher; Android 7.0 or higher. Specifications: YoLink Hub Input: 5V DC Maximum Current: 1A Working Temperature: -20C50C (-4F104F) Humidity: 090% non-condensing YoLink Water Leak Sensor Product Model: YS7903-UC Voltage: 3V DC (2 AAA battery) Working Temperature: 0C50C (32F122F) Working Humidity: 100%RH (non-condensing) Package Content: 1 x YoLink Hub 6 x YoLink Smart Water Leak Sensor.

Review: These sensors work really well and are easy to set up with the phone app. The hub is equally easy to set up. Paired with one of Yolink's motorized water shut-off valves, my home is well protected against leaking water and burst water lines.
Review: Not too difficult to set up. We haven't had a leak yet, so I don't know for sure that it works. However, I did test each sensor by putting a damp paper towel on them, and they all worked properly. So, I'm feeling much better about going out of town during winter.

*by C***R on 31 December 2025*

Fantastic product! Got an alert last week from the sensor in my water heater closet, had just barely begun to leak. It would’ve taken probably weeks for me to find out otherwise. Got a new water heater installed yesterday. Saved me a lot on floor and wall damage and who knows what else. Well worth the money!
