2026 verdict
Same sensor, different radio: the Fibaro Flood Sensor (HomeKit) takes this water leak sensor comparison on price and on integrations, reaching Apple HomeKit directly over Bluetooth plus Home Assistant, something the Z-Wave version cannot match without an extra bridge. The Fibaro Flood Sensor (Z-Wave) answers with a higher owner rating, appealing to buyers whose Z-Wave controllers pair more consistently than Bluetooth range allows. Both share the same compact body, water, temperature and tilt sensing, tamper alerts, and optional wired backup power. Pick the Fibaro Flood Sensor (HomeKit) if you run Apple Home and want native pairing without a Z-Wave hub; choose the Fibaro Flood Sensor (Z-Wave) if you already have a Z-Wave controller and want the better-reviewed version.
