What the differences mean

A cable, or temperature instead

The Switchbot Water Leak Detector (Sensor Cable Edition) includes a sensor cable, so the body and the cable tip can watch two places. It does not sense temperature, tilt or tamper. The Fibaro Flood Sensor (HomeKit) has no cable in the box, and it does sense temperature, tilt and tamper, with freeze alerts. Two wet spots favor the cable. A cold pipe and a tamper check favor the Fibaro.

How many platforms

The Switchbot Water Leak Detector (Sensor Cable Edition) supports Google Home, Apple Home, SmartThings and Home Assistant over Wi-Fi and Bluetooth, with no separate hub required. The Fibaro Flood Sensor (HomeKit) supports Apple Home and Home Assistant over Bluetooth to an Apple home hub. Google Home, Alexa, SmartThings and Matter are not supported on the Fibaro. Alexa and Matter are not supported on the SwitchBot either.

Power options

Both are rated for 2 years. The SwitchBot uses two AAA cells. The Fibaro uses a CR123A and lists optional wired power, so the battery can be backup if you can run a low-voltage lead. Low-battery alerts are not documented on either. If there is no way to run a wire, that Fibaro option does not help, and the AAA cells are the easier refill.

Sealing

The Switchbot Water Leak Detector (Sensor Cable Edition) is IP67. Weather resistance on the Fibaro Flood Sensor (HomeKit) is not documented, so only the SwitchBot has a published seal. Both have a sound and a light. Owners of the cable edition say that siren can be hard to hear through a closed door, which is a placement issue, not a missing feature. Both weigh in a similar range. The Fibaro is listed at 59 g and the SwitchBot at 109 g.

What owners say

Both groups say the alarm caught a leak in time. They do not praise the same extra. Fibaro Flood Sensor (HomeKit) owners talk about HomeKit pushes plus the sound and light, temperature used for freeze routines, and cells that still read strong after a year. They complain about Bluetooth range, the lack of a remote silence, and homes that needed another Apple hub. Switchbot Water Leak Detector (Sensor Cable Edition) owners talk about Wi-Fi with no extra hub and a cable that watches a second spot, such as a heater pan and a drip tray. They praise sensitivity and quick alerts, then complain that the battery door is stiff, the included pry tool breaks, and the siren is quieter through a cabinet door than the rating suggests.
