Yes. The Shelly Flood reads temperature and raises temperature and freeze alerts, which makes it useful near a pipe in a cold space. The YoLink Water Leak Sensor 1 has no temperature sensing and cannot warn about freezing.

No. The Shelly Flood connects straight to Wi-Fi and is set up from a phone browser with no app. The YoLink Water Leak Sensor 1 does need a YoLink hub, sold separately, to reach the app and its automations.

The YoLink Water Leak Sensor 1, rated for up to five years on two AAA batteries, against roughly 18 months on a single CR123A for the Shelly Flood, which is not included in the box. The Shelly uses more power because it is a Wi-Fi device.
