Ring Flood & Freeze Sensor

The Ring Flood & Freeze Sensor detects water leaks and freezing temperatures inside the home. It sends instant alerts through the Ring app and Alexa so homeowners can respond before damage spreads. No separate hub or base station is required for operation.

Amazon Sidewalk connectivity

Connectivity relies on the Amazon Sidewalk network, which covers approximately 95% of the US population. The sensor switches automatically to this free nationwide network when home Wi-Fi is unavailable, maintaining alerts without a local gateway.

Battery life and placement limits

Two included AA alkaline batteries are rated for up to 6 years of use, though actual life varies with event frequency and distance to the nearest Sidewalk Gateway. The compact 70 x 70 x 25.9 mm housing fits under sinks, near water heaters, or in crawl spaces.
