5 Best Water Leak Detectors (2022): Smart Water, Temperature and Humidity Sensors

Here’s what you need to consider when buying a smart leak detector and installing it in your home.

Placement and Sensors: Unless you are monitoring a single problem point or piece of equipment, you may need multiple leak detectors. Most have cables with sensors at the ends, some have water sensing lines, and some are self-contained. You can also choose an extension node with some detectors. Think about the area you want to cover, and consider which detector is best for you and how much you need.

alarm: All smart water leak detectors we tested send push notifications when water leaks, but some also send emails and text messages. Most have some sort of built-in siren sound, but some offer separate sirens or can be configured to send alerts through smart speakers or other devices. It’s worth checking if your selection supports disconnect alerts to warn you if the connection is lost, which can happen if there’s a power or Wi-Fi failure.

strength: Most detectors are battery powered, but you can buy some that plug directly into an outlet. You can set and forget the plug-in detector, but the battery gives you more flexibility in placement, and the companion app will usually warn you when the battery needs to be replaced.

Wifi: Most smart water leak detectors connect directly to your Wireless Router or hubs, so wherever you install them make sure you have a good signal. Most of the devices we tested only connect to Wi-Fi in the 2.4-GHz band. Remember, they need internet access to alert you of any leaks or issues when you’re not home. They only act as local alerts if your internet goes down.

Smart Home Integration: While companion apps and mobile notifications are typical, some detectors support the smart home standard, which allows you to access the detector and set triggers or automations in the smart home app of your choice.For example, you can set a water alarm to flash your smart light Or there may be a specific temperature that triggers the heating or air conditioning to turn on.

automatic water stop: On some high-end systems, you can install a water monitoring device with an automatic shut-off feature, enabling any leak detection to shut down your water supply. But these systems are often expensive and may require professional installation.

Temperature and humidity monitoring: Some smart water leak detectors can also monitor temperature and humidity, possibly alerting you to the danger of icy pipes or wet conditions, which could indicate a nearby leak. You can usually see temperature and humidity over time, so you can immediately spot any significant changes that need to be investigated. Coupled with smart home automation, you can also trigger heating or fans to some extent to reduce the risk of damage.
