The METAK WD61 system is a straightforward solution for monitoring multiple water trouble spots. Its core strength is the six included sensors, letting you cover a basement sump, water heater, washing machine, and under-sink cabinets simultaneously without buying expensive individual units.

When a sensor detects moisture, two things happen immediately. A piercing 120dB alarm sounds on the spot, loud enough to hear from another room. Simultaneously, the gateway sends a push notification to your phone via the Tuya Smart app. The setup requires a 2.4GHz Wi-Fi network, a common but important detail for compatibility. The included AAA batteries mean you can place sensors anywhere without hunting for an outlet.

You’ll need to keep the gateway plugged in and within range of all sensors. The app-based control gives you peace of mind when you’re away, turning a potential disaster into a manageable alert you can act on quickly.
