Updated December 2025

It carries a higher owner rating, a longer battery life and layers in temperature and tilt sensing that the Meross's leak-only design skips entirely. The Meross Smart Water Leak Sensor answers with a lower price and a wider integration list, reaching Samsung SmartThings as well as Apple HomeKit and Home Assistant, and it carries a documented IP67 rating where Fibaro's is not listed. The catch with Meross is its own hub: several owners describe the separate Smart Wi-Fi Hub periodically dropping offline and needing a manual restart, which quietly breaks remote alerts until someone notices. Most Apple Home households comparing these two should take the Fibaro Flood Sensor (HomeKit) for the added sensing and the stronger rating, and consider the Meross Smart Water Leak Sensor mainly for its lower price and its SmartThings support.

What the differences mean

Sensing

The Fibaro Flood Sensor (HomeKit) adds temperature and tilt sensing feeding freeze and tamper alerts. The Meross Smart Water Leak Sensor detects water leaks only.

Getting online

The Fibaro Flood Sensor (HomeKit) pairs over Bluetooth to an existing Apple TV, HomePod or iPad. The Meross Smart Water Leak Sensor needs its own separately paired Smart Wi-Fi Hub, which some owners report periodically drops offline.

Platform reach

The Meross Smart Water Leak Sensor adds Samsung SmartThings on top of Apple HomeKit and Home Assistant, one more platform than the Fibaro Flood Sensor (HomeKit) lists.

Weather resistance

The Meross Smart Water Leak Sensor carries a documented IP67 rating. The Fibaro Flood Sensor (HomeKit)'s rating is not documented.

Battery life

The Fibaro Flood Sensor (HomeKit) is rated for about 2 years on its CR123A cell, longer than the roughly 1.5 years the Meross Smart Water Leak Sensor gets from the same battery type.

Which one to buy if

What owners say

Owners of the Fibaro Flood Sensor (HomeKit) describe fast HomeKit pairing and a battery that still reads close to full after a year or more, and several specifically credit its tilt and freeze sensing for catching more than a plain leak puck would. Meross Smart Water Leak Sensor owners praise the same easy HomeKit pairing and the compact IP67 housing, and multiple reviewers on both sides of the Atlantic say the sensor caught a real leak early, but the most serious and most repeated complaint is the separate Meross Smart Wi-Fi Hub losing its connection roughly monthly and needing a manual power cycle before alerts resume, with a smaller group also calling the on-device alarm too quiet to rely on.

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.
