The sensors are battery-powered, using AAA batteries that are included, making it convenient right out of the box. The alarm itself is quiet, but the system compensates by sending SMS, email, and push notifications, ensuring you receive alerts even if you're not home.

Connectivity is achieved through the YoLink Hub, which requires an ethernet connection or WiFi (2.4GHz only).

Buying Guide for the Best Water Alarms

Water alarms are essential devices that help detect leaks or flooding in your home, providing an early warning to prevent water damage. Choosing the right water alarm involves understanding various specifications and how they align with your specific needs. Here’s a guide to help you navigate through the key specs and make an informed decision.
Detection MethodThe detection method refers to how the water alarm senses the presence of water. Common methods include sensors that detect moisture or water levels. This spec is important because it determines the reliability and accuracy of the alarm. Moisture sensors are great for detecting small leaks, while water level sensors are better for areas prone to flooding. Choose a detection method based on the type of water issues you are most likely to encounter.
Power SourceWater alarms can be powered by batteries, AC power, or a combination of both. This spec is crucial as it affects the installation flexibility and maintenance. Battery-powered alarms are easy to install and can be placed anywhere, but require regular battery changes. AC-powered alarms are more reliable for continuous operation but need a nearby power outlet. Consider your installation location and preference for maintenance when choosing the power source.
Alarm VolumeThe alarm volume indicates how loud the alarm will sound when it detects water. This is important to ensure you can hear the alarm from different parts of your home. Alarm volumes typically range from 85 decibels (dB) to over 100 dB. For small homes or apartments, a lower volume may suffice, while larger homes or noisy environments may require a louder alarm. Choose an alarm volume that ensures you will be alerted promptly, regardless of your home's size or noise level.
ConnectivitySome water alarms offer connectivity features such as Wi-Fi or Bluetooth, allowing them to send alerts to your smartphone or integrate with smart home systems. This spec is important for remote monitoring and immediate notifications. If you travel frequently or want to monitor your home while away, a connected water alarm can provide peace of mind. Evaluate your need for remote alerts and smart home integration when considering connectivity options.
Installation TypeThe installation type refers to how and where the water alarm can be installed. Options include floor-mounted, wall-mounted, or even floating alarms. This spec is important for ensuring the alarm can be placed in the most effective location. Floor-mounted alarms are ideal for basements or under appliances, wall-mounted alarms work well near pipes or water heaters, and floating alarms are suitable for sump pumps or pools. Choose an installation type that matches the specific areas you need to monitor.
DurabilityDurability refers to the water alarm's ability to withstand harsh conditions, such as high humidity or direct water exposure. This spec is important for ensuring the alarm remains functional in challenging environments. Look for alarms with water-resistant or waterproof ratings if you plan to use them in areas prone to heavy moisture or direct water contact. Consider the environment where the alarm will be placed and choose a durable model that can handle those conditions.
