2026 verdict
For Apple Home users who want more than a leak alert, the Fibaro Flood Sensor (HomeKit) is the better all-rounder than the Eve Water Guard.

Fibaro Flood Sensor (HomeKit)Last recorded priceJan 1, 2026$43.28
Currently unavailable on Amazon USA
It adds a temperature sensor with temperature and freeze alerts, plus a tilt sensor with tamper alerts, and runs on a battery so it can go anywhere. The Eve Water Guard is built for a different job: a long sensing cable that watches an entire kitchen or laundry run from one unit, a Thread connection alongside Bluetooth, and wall power instead of batteries. Both work with Apple Home and Home Assistant, and both have a siren and a light. Pick the Fibaro Flood Sensor (HomeKit) for spot sensors with freeze and tamper warnings, and the Eve Water Guard when one device has to cover a whole row of appliances near an outlet.

What the differences mean
Coverage area
The Eve Water Guard uses a sensing cable, so it detects water anywhere along it, behind a whole row of appliances. The Fibaro Flood Sensor (HomeKit) detects water only where the puck sits, so a long run needs several of them.
Temperature, freeze and tamper
The Fibaro Flood Sensor (HomeKit) measures temperature, sends temperature and freeze alerts and raises a tamper alert when it is tilted or moved. The Eve Water Guard detects water only.
Power
The Eve Water Guard needs wall power, so it has to live near an outlet but never needs a battery. The Fibaro Flood Sensor (HomeKit) runs about 2 years on a CR123A cell and can optionally be powered from a DC supply.
Connection
The Eve Water Guard uses Thread with a border router, as well as Bluetooth. The Fibaro Flood Sensor (HomeKit) uses Bluetooth only, so its range depends on how close an Apple TV, HomePod or iPad is.
Which one to buy if
- you want to guard a long kitchen or laundry run with one device
The Eve Water Guard's sensing cable covers the whole stretch, not a single spot.
- pipes could freeze where the sensor goes
Only the Fibaro Flood Sensor (HomeKit) has temperature and freeze alerts.
- there is no outlet near the leak point
The Fibaro Flood Sensor (HomeKit) runs on a battery; the Eve Water Guard needs wall power.
- your home has a Thread network and a large floor plan
The Eve Water Guard uses Thread, while the Fibaro relies on Bluetooth range to a HomeKit hub.

What owners say
Owners of both are Apple Home users, and both groups report sensors that caught a real leak with a fast Home app alert plus a local siren and light. Eve Water Guard owners single out the sensing cable that covers a full appliance run, the account-free HomeKit setup and having no batteries to change. Fibaro Flood Sensor (HomeKit) owners single out the temperature reading for freeze automations, the tilt alarm and batteries still near full after a year. Their complaints differ: Eve owners mention the higher cost, the need for a nearby outlet, a cable that has to absorb a little water before it triggers and a few units that stopped working, while Fibaro owners mention Bluetooth range that needed an extra Apple TV in larger homes, occasional dropouts and no way to silence the alarm remotely.
