Aqara Water Leak Sensor vs Aqara Water Leak Sensor T1

Full Smart Water Leak Sensors comparison in 2026

Updated June 2026
Data from Amazon and official Aqara site.
2026 verdict
The Aqara Water Leak Sensor T1 edges out its older sibling as the better water leak sensor overall, thanks to a higher owner rating and noticeably wider integrations: where the original Aqara Water Leak Sensor only bridges to Apple HomeKit through an Aqara Hub, the T1 adds Google Home, Alexa and Matter through the same hub. Physically these two are twins, both 50 x 50 x 15 mm, both IP67, both running roughly two years on a single CR2032 over Zigbee, so this really comes down to platform reach versus cost. The original Aqara Water Leak Sensor stays relevant as the cheaper of the pair, and it remains a strong, discreet Zigbee choice if HomeKit or Home Assistant is your only target. Pick the Aqara Water Leak Sensor T1 for the broadest hub-bridged integrations and the higher rating; save a little with the Aqara Water Leak Sensor if you only need HomeKit or Home Assistant.
