In Stock Only Smoke Detectors

The Moen Flo Detector is a WiFi-enabled moisture sensor that can be placed near sinks, appliances, and other water-risk areas in your home. When it detects water where it shouldn’t be, the Flo Detector sends an immediate alert through the Moen Flo App, and can automatically trigger the Flo Shutoff to turn off your water. Most leak detectors stop at the alert, but the Flo Detector goes further. The moment it finds moisture, it sounds an audible alarm, emits a blinking LED light, and sends a real-time notification through the Moen Flo App so you know about water and moisture, whether you are home or away, before it becomes a problem. Pair the Flo Detector with the Moen Flo Shutoff for complete whole-home coverage. When the two work together, the Flo Detector triggers the Shutoff to automatically close the moment moisture is found. Stay in control from anywhere with the Moen Flo App, and add a FloProtect plan for extended warranty coverage and insurance deductible support. Water damage is the most underestimated threat inside a home; more common than fire and more costly than theft. Moen Flo exists to change that. We prevent loss, one drip at a time.
