It features six highly sensitive detection probes (top and bottom), an integrated siren up to 90 dB, waterproof IP67 rating, and instant notifications via the Tapo app. When paired with a compatible Tapo Hub, it can also trigger smart actions such as activating lights or other devices when a leak is detected — making it ideal for basements, laundry rooms, bathrooms, near washing machines or under sinks.
