What the differences mean

Apple Home

The Fibaro Flood Sensor (HomeKit) works natively in Apple Home through an Apple TV, HomePod or iPad. The YoLink Water Leak Sensor 4 does not work with Apple Home at all, so for an iPhone-centred home this settles it.

Range

The YoLink Water Leak Sensor 4 reaches its hub over LoRa, built for long distances and outbuildings. The Fibaro Flood Sensor (HomeKit) relies on Bluetooth to the nearest Apple hub, so a big or concrete-walled house may need a second hub.

Battery life

The YoLink Water Leak Sensor 4 is rated for about 5 years on two AAA batteries and sends low battery alerts. The Fibaro Flood Sensor (HomeKit) is rated for about 2 years on a CR123A, can be wired to 12/24V DC, and its low battery alerts are not documented.

Tilt and tamper

The Fibaro Flood Sensor (HomeKit) reports being tilted or tampered with; the YoLink Water Leak Sensor 4 does not.

What owners say

Owners of both tell of real leaks caught early, a sump pump or a water heater, and value the local alarm next to the phone notification. YoLink Water Leak Sensor 4 owners single out range that reaches garages and outbuildings, a siren that sounds even with the hub offline and years on one set of batteries, but a few found the YoLink app confusing to configure. Fibaro Flood Sensor (HomeKit) owners praise fast setup into the Home app, freeze automations and the tilt and tamper sensor, while those in larger homes needed an extra Apple TV to keep it in Bluetooth range, and several wish they could silence the alarm remotely.
