Meross Smart Water Sensor Alarm 3 Pack – HomeKit & SmartThings Leak Detector, IP67, 100m Range

Smart leak sensing, simplified

Meet the Meross Smart Water Sensor Alarm 3 Pack, a compact kit designed to monitor moisture and help you respond quickly. These sensors use highly responsive probes to detect even tiny water incursions and connect to your home network through the included Meross hub. When a threshold is reached, you’ll hear a local alarm and see a bright indicator light, while the Meross app pushes a notification to your phone. The IP67-rated enclosure is built to withstand humidity and splashes, making them suitable for basements, laundry rooms, kitchens, and near sump pumps.

Setup is straightforward: place the sensors where leaks matter, link them to Apple HomeKit via bridge and/or SmartThings, and you’re ready to monitor remotely. The system supports multiple automation rules, so a leak can trigger a connected Meross device such as a plug that powers down a pump, helping to limit damage before it grows. A single Meross hub can manage up to 16 sensors, so you can cover broad areas without clutter or dead spots.
