TP-Link T300 Smart Water Leak Detector: 1-second rapid detection and response with dual-side sensing
For the homeowner who wants to protect their basement, laundry room, or under-sink areas from costly water damage, the Tapo T300 is your first line of defense. While many water leak detectors focus on basic alerts, this sensor offers peace of mind for a busy family by acting as a proactive guardian against hidden drips.
Its dual-side sensing catches leaks from above and below, so you know about a slow drip under the washing machine before it soaks the floor. The 90dB alarm is loud enough to hear from another room, and the app notification arrives instantly, often before you even notice the issue. With a 3+ year battery life, you can set it and forget it, knowing it's always on watch.
