Instant Flood and Temperature Alerts

sleek and functional design

Unlike other water sensors, Floodie can be placed horizontally or vertically for optimal flood detection. Floodie is also waterproof which means it’s reusable even after it gets wet.

24/7 leak & flood monitoring

Even a power outage can’t stop Floodie from sending leak and flood alerts when it detects water. Floodie is designed to send flood alarms only when the contacts detect water, not moisture or humidity.

Minimized false alarms

Low battery notifications

Long range leak and flood detection

The most common places to experience water damage are around water heaters, water softeners and toilets. Place Floodies in these areas up to 1000 ft. (300 m) from an Alert Labs cellular sensor for complete property protection.
