Fibaro Flood Sensor (Z-Wave) vs Heiman Smart Water Leakage Sensor

The Heiman Smart Water Leakage Sensor wins overall on price, owner rating, weatherproofing, battery life and integrations. The Fibaro Flood Sensor (Z-Wave) answers with a deeper onboard sensor set and more alert types.

Radio protocol and sensing breadth. The Fibaro Flood Sensor (Z-Wave) needs a Z-Wave controller and adds temperature and tilt sensing that drive tamper and freeze alerts, while the Heiman Smart Water Leakage Sensor connects over plain Wi-Fi, costs less and lasts longer on its battery, but detects water leaks only.

The Fibaro Flood Sensor (Z-Wave) does, requiring a Z-Wave controller to function at all. The Heiman Smart Water Leakage Sensor connects on its own over 2.4GHz Wi-Fi, though its remote alerts and smart features need a separately sold gateway.

Only the Fibaro Flood Sensor (Z-Wave). Its temperature sensor drives temperature and freeze-temperature alerts, and its tilt sensor triggers a tamper alert if the unit is moved.

Buyers who already run a Z-Wave hub or Home Assistant and want tamper and freeze detection built into the same compact puck as water-leak alerts.

Buyers who want the cheaper, better-rated, more weatherproof, longer-lasting and better-integrated sensor, and who are happy with water-leak detection alone.
