About This
- 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.
- Batteries Included: Enjoy peace of mind for over 2 years with two replaceable AAA batteries included. No need to worry about frequent replacements.
- What’s Included: This package includes 1 YoLink Hub and 1 Sensor—2 items total. The “Number of Items: 2” refers to the two individual products in the package, not two sensors.

SMART HOME FAQ
Yes — many modern devices support multiple platforms.
Matter-certified devices can work across Alexa, Google Home, and Apple HomeKit at the same time.
Not always.
Smart bulbs, plugs, cameras, and video doorbells are often easy DIY installations, while full security systems may need professional setup.
Many devices still work manually or through local control.
You may lose remote app access, but locks, lights, and thermostats often continue basic functions.
Security depends on the device and setup.
Use strong passwords, trusted brands, firmware updates, and secure Wi-Fi for better protection. Privacy and unauthorized access are common concerns in smart homes.
Most homeowners start with:
Smart Security Cameras
Smart Door Locks
Smart Thermostats
Smart Plugs
Video Doorbells
Yes.
Smart thermostats and smart plugs help reduce wasted energy by automating heating, cooling, and power usage.
It depends on your ecosystem.

Google Home → strong for Android users
Apple HomeKit → best privacy
Home Assistant → advanced control
