YoLink Water Leak Detector 4 – 105dB Alarm, Freeze Warning, 1/4 Mile LoRa Range, Hub Required

Protect your space with the YoLink Water Leak Detector 4

Meet a leak detector built for real homes and small businesses. It uses a private LoRa network to report from far away, without relying on your WiFi. The device sends alerts through the YoLink app, emails, and limited text, helping you stay informed even when you are away from the premises.

With a robust 105dB alarm and an IP66 rating, this sensor is designed for reliability in a variety of environments. Its long-range communication reaches up to a 1/4 mile in open air, making it suitable for basements, garages, sheds, and other hard-to-reach spaces. A built-in freeze warning helps you spot temperature drops before pipes are at risk, adding another layer of protection during colder months.

Installation is quick and straightforward. Place the sensor near toilets, water heaters, laundry machines, sinks, or sump pumps, then connect it to a YoLink Hub to unlock full functionality. The system communicates locally with the Hub, preserving privacy and avoiding external network dependencies.

Smart features extend beyond alerts. You can enable app push notifications, email alerts, and limited text notices to suit how you prefer to monitor your property. Compatibility with Alexa and IFTTT broadens automation possibilities, while the Hub remains the central controller for your expanding YoLink ecosystem.
