What kind of battery power does the Ring Flood & Freeze Sensor use, and how long can it last?

It is powered by 2 included AA alkaline batteries and is rated for up to 6 years of battery life. Actual battery life depends on the number of events, proximity to a Sidewalk Gateway, and other factors.

How does the Ring Flood & Freeze Sensor connect, and does it need a hub or Wi-Fi range to work?

It connects automatically over Amazon Sidewalk, so no hub or base station is required. It also does not depend on your home Wi-Fi range, and it can stay connected even if your home Wi-Fi drops.
