SwitchBot W4402010 WiFi Water Leak Detector: Real-time app and email alerts
For the homeowner who wants to protect their basement, laundry room, or under-sink areas from costly water damage, the SwitchBot Water Leak Detector offers proactive peace of mind. While many focus on simple alerts, this device acts as your first line of defense, catching leaks before they escalate into major repairs.
Its high-sensitivity probes detect moisture as shallow as 0.5mm, so you get an app notification the moment a pipe starts dripping—often before any visible puddle forms. The included 1-meter cable lets you monitor hard-to-reach spots like behind the water heater or inside the washing machine. You can share access with family members, so everyone stays informed.
With a loud 100dB alarm and IP67 waterproof rating, it works reliably in damp environments for up to two years on included batteries. Integrate it with your home security camera or smart plug via the SwitchBot ecosystem, and use Alexa compatible voice commands for hands-free control. This indoor detector ensures your home stays dry and secure.
