YoLink Water Leak Sensor 3-Pack | LoRa Long-Range, Hub Required

Meet YoLink Water Leak Sensor 3-Pack—a robust line of wireless detectors that keep you informed without relying on traditional WiFi. Built on LoRa technology, each sensor communicates with the YoLink Hub up to 1/4 mile away in open air, delivering encrypted messages that resist interference and help you respond quickly when moisture appears where it shouldn’t.

In real-life scenarios, you’ll place these near toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, sump pumps, or any area prone to leaks. The long-range design shines in spaces where WiFi signals are patchy—basements, outdoor porches, sheds, or detached garages—so you can monitor more of your property with confidence.
