Updated September 2026

Data from Amazon and official Aqara and Ring sites.

2026 verdict

Leak-only sensing versus freeze alerts, IP67 versus IP66 weather resistance shows the gap, and the Aqara Water Leak Sensor T1 is the water leak sensor that fills it with IP67 weather resistance.

Add wider smart-home integrations, the more affordable option, and the stronger owner reviews and the gap is structural, not a sale price. The radios differ too: Aqara Water Leak Sensor T1 has no extra long-range radio, and Ring Flood & Freeze Sensor (2nd Gen) uses Amazon Sidewalk. Ring Flood & Freeze Sensor (2nd Gen) keeps 6 years of battery life, a wider sensor set, and a broader connectivity mix, so it remains the pick when that priority beats IP67 weather resistance. Shop the Aqara Water Leak Sensor T1 unless 6 years of battery life is the only thing you came for, in which case the Ring Flood & Freeze Sensor (2nd Gen) is enough.
