It also lands an on-device alarm, better weather resistance, and an on-device alert light. Eve Water Guard 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 a wider sensor set, richer alert options, and the more affordable option, so it remains the pick when that priority beats an on-device alarm. Choose the Eve Water Guard for an on-device alarm; keep the Ring Flood & Freeze Sensor (2nd Gen) only when a wider sensor set is the whole brief.
