What the differences mean
Z-Wave hub or plain Wi-Fi
The Fibaro Flood Sensor (Z-Wave) has no Wi-Fi, Bluetooth, Zigbee or Thread. It needs a Z-Wave hub. The Switchbot Water Leak Detector (Sensor Cable Edition) lists 2.4 GHz Wi-Fi and Bluetooth and does not need a separate hub. If Z-Wave is already the backbone, the Fibaro drops in. If it is not, the SwitchBot avoids buying a controller just to hear about a leak.
Cable versus freeze and tamper
The SwitchBot includes a sensor cable and does not sense temperature, tilt or tamper. The Fibaro Flood Sensor (Z-Wave) has no cable, and it does sense temperature, tilt and tamper, with freeze alerts. Two wet points favor the cable. A cold pipe, a moved sensor, or a tamper check favors the Fibaro. You do not get the cable and the freeze sensor in one of these two boxes.
Platforms past the hub
The Switchbot Water Leak Detector (Sensor Cable Edition) supports Google Home, Apple Home, SmartThings and Home Assistant. The Fibaro Flood Sensor (Z-Wave) supports SmartThings and Home Assistant only. Google Home, Alexa, Apple Home and Matter are not supported on it. Alexa and Matter are not supported on the SwitchBot either. Apple Home and Google Home are the practical SwitchBot gains.
Seal, sound and power
Both have an on-device sound and light. The SwitchBot body is IP67 and rated for 2 years on two AAA cells. The Fibaro is rated for 2 years on a CR123A, with optional wired power, listed at 59 g against 109 g. Weather resistance on the Fibaro is not documented. Low-battery alerts are not documented on either. Warranty is 1 year on both. The siren is a tie on the sheet. Owners of the cable edition still say doors muffle it.
Which one to buy if
- you do not want to buy a Z-Wave hub for one leak sensor
The Switchbot Water Leak Detector (Sensor Cable Edition) joins Wi-Fi and Bluetooth directly and includes a cable for a second spot.
- you want Z-Wave to also catch a freeze, tilt or tamper
The Fibaro Flood Sensor (Z-Wave) adds those on top of the leak alarm, with SmartThings and Home Assistant.
- you need Apple Home or Google Home to see the sensor
Both are supported on the cable edition and not on the Fibaro Flood Sensor (Z-Wave).
- you can run a low-voltage lead and want battery backup only
Optional wired power is listed on the Fibaro Flood Sensor (Z-Wave). The SwitchBot cable edition is battery only.

What owners say
Both groups like a sensor that makes a noise, then they describe a different install. Fibaro Flood Sensor (Z-Wave) owners talk about pairing in seconds once Z-Wave is already there, temperature used as a freeze check, and tilt and tamper as a bonus, with wired power as backup for the CR123A. A few hit a hub that misidentified the device, and several wanted a probe that is not in the box. Switchbot Water Leak Detector (Sensor Cable Edition) owners talk about Wi-Fi with no extra hub and a cable that covers a second spot, such as a heater pan. They praise fast, sensitive alerts, then complain about a stiff battery door, a pry tool that breaks, and a siren that is harder to hear through a cabinet than they expected.
Frequently Asked Questions
Which is better overall: Fibaro Flood Sensor (Z-Wave) or Switchbot Water Leak Detector (Sensor Cable Edition)?
The Switchbot Water Leak Detector (Sensor Cable Edition) unless you already depend on Z-Wave. It brings Wi-Fi, a cable, IP67, and Google Home, Apple Home, SmartThings and Home Assistant. The Fibaro Flood Sensor (Z-Wave) adds temperature, tilt and tamper that the cable edition does not have.
What is the biggest difference between the Fibaro Flood Sensor (Z-Wave) and the Switchbot Water Leak Detector (Sensor Cable Edition)?
The Fibaro is a Z-Wave temperature, tilt and tamper sensor with no cable. The SwitchBot is a Wi-Fi leak sensor with a cable, an IP67 body, and no temperature sensing. Both have a sound and a light and a 2-year battery rating.
Does the Switchbot Water Leak Detector (Sensor Cable Edition) work with Apple Home?
Yes. Apple Home, Google Home, SmartThings and Home Assistant are supported, over Wi-Fi and Bluetooth. The Fibaro Flood Sensor (Z-Wave) does not support Apple Home, Google Home or Alexa. It supports SmartThings and Home Assistant through Z-Wave.
Which one includes a probe cable?
The Switchbot Water Leak Detector (Sensor Cable Edition) includes a sensor cable. The Fibaro Flood Sensor (Z-Wave) does not. The Fibaro instead offers temperature, tilt, tamper and optional wired power.
Who should buy the Fibaro Flood Sensor (Z-Wave)?
Buy the Fibaro Flood Sensor (Z-Wave) for an existing Z-Wave or Home Assistant setup that should sense leaks, freezes, tilt and tamper, with a local sound and light.
Who should buy the Switchbot Water Leak Detector (Sensor Cable Edition)?
Buy the Switchbot Water Leak Detector (Sensor Cable Edition) to cover two leak points on Wi-Fi, with Apple Home or Google Home, and no Z-Wave hub. It will not warn you about a freeze.
