Product Details
✓No WiFi Worries: Say goodbye to WiFi dependency! YoLink devices use industrial-grade LoRa protocol for communication, offering an impressive ¼ mile open air range. They don't connect to your network or the internet; they communicate securely with the Hub (Hub not included!). Enjoy obstruction-penetrating, long-range coverage without compromising your privacy.
✓Effortless Installation: Set it and forget it! Installing the YoLink wireless Water Sensor takes seconds. Simply place it near or under the equipment you want to monitor. Perfect for toilets, water heaters, laundry machines, dishwashers, sinks, fish tanks, sump pumps, and any other water-prone areas.
✓Extreme Long Range: Powered by LoRa technology, our system offers the industry's longest receiving range (1/4 mile). Overcome WiFi limitations and monitor areas like basements, outdoor spaces, sheds, garages, and remote outbuildings with ease.
✓Powerful 105dB Audio Alarm: Be instantly alerted to potential leaks with our water leak detector's robust 105dB audio alarm. Swiftly respond to emergencies and protect your space from water damage.
✓IP66 Waterproof Protection: Designed to endure various conditions, our water leak detector boasts an impressive IP66 waterproof rating. Count on its reliability indoors.
✓Built-in Freeze Warning: Equipped with a low temperature sensor, the Yolink Water Leak Sensor not only detects leaks but also alerts you when the temperature drops to freezing levels, helping you prevent frozen pipes and potential damage during colder months.
✓Start Smart: A YoLink hub is your gateway to full functionality. Connect with a growing range of smart home and business products. Find our SpeakerHub (B0BZBYD1MK or B09FSS95G9 for audio capabilities) or the original Hub (B08CBTTD17 or B07TQLKQLJ).
