That same sheet lists an on-device alarm, a wider sensor set, and richer alert options. Fibaro Flood Sensor (Z-Wave) can sound an alarm in the room, whereas Ring Flood & Freeze Sensor (2nd Gen) stays quiet and leans on phone or hub alerts. Ring Flood & Freeze Sensor (2nd Gen) keeps IP66 weather resistance, 6 years of battery life, and a broader connectivity mix, so it remains the pick when that priority beats an on-device alarm. The practical recommendation is the Fibaro Flood Sensor (Z-Wave) for the fuller water leak sensor spec, with the Ring Flood & Freeze Sensor (2nd Gen) reserved for buyers who prize IP66 weather resistance.
