1/4 Mile Super Long Range Wireless Leak Sensor LoRa enabled Smart Water Leak Detector Alert Notification App Alerts History Logs Sensor with Sensitive Leak Probes, YoLink Hub Required

Works very well and detects water, notifications are excellent

This device, like the other ones in the YoLink family, is exceptionally easy to put into service and well-built which gives me confidence in its reliability. I've stationed these water sensors all over the house now, having bought a bunch more. I've rigged it so that sensing a water condition (drip, spill, flood, etc.) will sound an alarm in my home office, notify me and my wife on our cell phones (by way of the app), and send me an SMS text message. I plan to get YoLink's 110dB alarm unit too, but haven't yet. Every once in a while, I test the alarm system by putting a random sensor (say, the one under the kids' bathroom sink) in a small puddle on the countertop just to reassure me that all is still operational. I really like this system! Also, the door sensors are great because it helps me keep tabs on who's filching the junk food from the basement pantry! (I pretend the door sensor is there to ensure we close the insulated door...)

This is the eu version that operates on a different frequency to the us hubs. It does not connect to my hub

I didn't know what to expect, but I heard this product was good. It arrived quickly, was REALLY easy to install and connect with the mobile app. Works perfectly. I have 5 installed in my condo and another 4 installed in my country cottage. You can view their functions by house, location, etc. Highly recommended. Try to wait for a sale, since they are kind of pricey, but they are certainly good.

Great if you need to be away and leave water on
