Out performs the Competition

The SW-A11KT stands above other brands with superior connectivity, flexibility, and ease of use. Here’s why this is the best water leak detector for home protection:

  • Unique Water Sensing Cable: The master unit includes a flexible water sensing cable that senses water along its full 1.5 ft. length.
  • No Hub Required – Truly Plug-and-Play: Unlike systems that need a separate hub, ours is all-in-one. Just connect the main unit to Wi-Fi—no extra pieces or costs.
  • Stronger, Longer Range Signal: Many Wi-Fi sensors struggle with distance and walls. Our sub-GHz wireless tech reaches up to 1000 ft for reliable coverage in basements, lofts, and large homes.
  • More Sensors, More Coverage: Supports up to 16 sensors—more than many competitors—so you can monitor every risk area without juggling multiple systems.
  • Built-In Alarm & Strobe: While others rely only on phone alerts or extra accessories, our main unit includes a 100 dB siren and flashing LED, helping ensure that no leak goes unnoticed.
  • Works with your Google speaker: For even more peace-of-mind, connect the system to your Google Assistant speaker or display and have it shout a warning when water is detected.

The SW-A11KT delivers unmatched range, coverage, and reliability—all with simple, hassle-free setup.

Water damage is one of the most expensive and disruptive home repair issues—but it’s often preventable. The D-Link SW-A11KT Smart Water Leak Sensor Kit gives homeowners an easy, affordable way to detect leaks early and respond quickly. With dual-sensor coverage (expandable to 17 locations by adding SW-A2 for each location), local alerts, and smartphone notifications via the AQUILA PRO AI app, it’s the smarter way to help protect your home—without monthly fees.

FAQs

The D-Link SW-A11KT Smart Wi-Fi Water Leak Sensor Starter Kit is a plug-and-play
solution that helps detect water leaks early—to help prevent or reduce costly damage. It includes a plug-in sensor with a built-in siren and strobe, plus a battery-powered remote sensor pod for added coverage under appliances or near sump pumps.

Unlike basic leak alarms, the SW-A11KT offers dual-sensor detection, smartphone
alerts, a 100 dB siren, and LED strobe. It also connects to Wi-Fi directly—no hub needed—and supports voice alerts via Google Assistant, giving you near real-time awareness from anywhere.

Place the main plug-in sensor near high-risk areas like water heaters, basements, or laundry rooms where you have access to a power outlet. The battery-powered pod fits under sinks, dishwashers, or behind toilets. You can expand the system with up to 16 total sensors for whole-home coverage.

When a leak is detected, the SW-A11KT triggers:

  • A loud 100 dB alarm
  • A flashing LED strobe
  • A push notification to your phone
  • A voice alert via Google Assistant (if enabled)

No. The SW-A11KT does not require a subscription, including alerts, app control,
and local siren/strobe activation.

The SW-A11KT works with the AQUILA PRO AI app, which lets you monitor leak alerts, check sensor status, and manage additional D-Link smart devices—all from your smartphone.

You can add up to 16 remote sensor pods (add model SW-A2 for each pod, sold separately) to the SW-A11KT system. This lets you monitor multiple rooms or areas like bathrooms, kitchens, garages, and basements for comprehensive coverage.
