Aqara Water Leak Sensor vs Fibaro Flood Sensor (Z-Wave) comparison

Updated July 2026

Data from Amazon and official Aqara and Fibaro sites.

2026 verdict

For a hub-based smart home that values sensing depth, the Fibaro Flood Sensor (Z-Wave) is the better water leak sensor, and it wins this matchup on a higher owner rating, more sensors (temperature and tilt alongside leak), more alert types including freeze and tamper, and an onboard alert sound and light the Aqara Water Leak Sensor lacks. The Aqara Water Leak Sensor answers on cost and reach: it is cheaper, IP67-rated where the Fibaro lists none, and far more connectable, bridging to Apple HomeKit and IFTTT through an Aqara Hub instead of relying purely on a Z-Wave controller. Note the Fibaro Z-Wave version has no native voice-assistant support beyond Home Assistant. Pick the Fibaro Flood Sensor (Z-Wave) for a higher-rated, multi-sensor unit with a local alarm inside a Z-Wave or Home Assistant setup; choose the Aqara Water Leak Sensor for a cheaper, waterproof sensor with broader integrations.
