This water leak sensor lists temperature, tilt, tamper alerts, a siren and a light on Z-Wave, with optional wired power and a CR123A rated for 2 years. The Eve Water Guard covers more floor: a 6.5 ft cable extendable toward 490 ft, Thread, Bluetooth and native Apple Home, plus a 100 dB siren, but only while it is plugged in. Choose the Fibaro Flood Sensor (Z-Wave) for a Z-Wave spot sensor, and the Eve Water Guard to trace a whole counter in HomeKit.

What the differences mean

Cable run versus one spot

The Eve Water Guard ships with a 6.5 ft sensing cable and can be extended up to about 490 ft, so a sink, fridge and dishwasher can share one sensor. The Fibaro Flood Sensor (Z-Wave) has no cable. It watches the spot under the puck, and it adds temperature, tilt and tamper that the Eve does not list.

Outlet versus battery

The Eve Water Guard is mains only. Placement ends at the cord, and a low-battery alert does not apply. The Fibaro Flood Sensor (Z-Wave) is rated for 2 years on a CR123A and lists optional wired power if you want both. A cupboard with no outlet is a Fibaro placement.

HomeKit and Thread versus Z-Wave

The Eve Water Guard lists Apple Home, Bluetooth and Thread, with a border router required, and Matter is marked as coming. It does not list Z-Wave, SmartThings or Google Home. The Fibaro Flood Sensor (Z-Wave) is Z-Wave only, lists SmartThings and Home Assistant, and does not list Apple Home. Home Assistant is listed for the Eve as well.

Shared siren, different extras

Both have an on-device alarm and a light. The Eve notes cite 100 dB. Only the Fibaro Flood Sensor (Z-Wave) adds freeze alerts, tilt and tamper. Weather resistance is listed simply as supported on the Eve, with no IP code in the sheet, and it is not documented on the Fibaro.

What owners say

Eve Water Guard owners describe a HomeKit add that does not ask for another account, a siren and light that caught real leaks, and one cable following a kitchen instead of a row of pucks. They call out the price and the wall plug, and a minority report a unit that failed to connect or stopped detecting. Fibaro Flood Sensor (Z-Wave) owners stay on size and trust: a puck that hides, pairs fast on Z-Wave, and reports temperature next to water so a cold pipe is not a second device. They accept that there is no probe in the box and no Apple Home on the sensor itself.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
