Updated October 2026
Data from Amazon and official Eufy and Fibaro sites.
2026 verdict
In a home built around Apple Home, the Fibaro Flood Sensor (HomeKit) is the more complete water leak sensor of these two, pairing over Bluetooth with no extra hub and sounding its own alarm.

It also flashes a light, senses tilt with tamper alerts, sends general temperature alerts as well as freeze warnings, works with Home Assistant, and can run from an optional 12/24V DC supply with the battery as backup. The Eufy Water and Freeze Sensor is the lower priced and better rated option, sealed to IP65, but it only works through a Eufy HomeBase, stays silent on the sensor itself and warns about freezing without general temperature alerts. Both run about 2 years on a lithium cell and neither works with Alexa or Google Home. Pick the Fibaro Flood Sensor (HomeKit) for Apple Home, and the Eufy Water and Freeze Sensor if a Eufy HomeBase already runs your cameras.

What the differences mean

Ecosystem

The Fibaro Flood Sensor (HomeKit) joins Apple Home over Bluetooth through an Apple TV, HomePod or iPad, and also works with Home Assistant. The Eufy Water and Freeze Sensor talks only to a Eufy HomeBase and lives in the Eufy app, with Home Assistant reachable only through a community integration.

Alarm on the sensor

The Fibaro Flood Sensor (HomeKit) sounds an alarm and flashes a light on the device. The Eufy Water and Freeze Sensor is silent itself; its audible warning comes from the HomeBase, which may be in another room.

Extra sensing

Both measure temperature and warn about freezing. The Fibaro adds general temperature alerts and a tilt sensor with tamper alerts, so it notices if someone moves it.

Range and power

Bluetooth range is the Fibaro's weak point: it needs a HomeKit hub within reach, and owners in larger homes added an Apple TV. In exchange it can run from a 12/24V DC supply. The Eufy relies on the HomeBase radio and a CR123 cell.

Sealing

The Eufy Water and Freeze Sensor is rated IP65. Fibaro does not publish a rating for the Fibaro Flood Sensor (HomeKit), so treat it as unknown rather than unprotected.

What owners say

Owners of both sensors describe leaks caught early and alerts that arrive fast, and both groups like the freeze warning next to the leak alarm. They diverge on the connection. Fibaro Flood Sensor (HomeKit) owners value the tilt and tamper sensing and batteries that still read nearly full after a year, but Bluetooth range is their recurring problem: in larger homes or behind concrete walls some needed another Apple TV as a repeater, a few had it drop offline, and some wish they could silence the onboard alarm remotely. Eufy Water and Freeze Sensor owners praise quick QR code pairing into the Eufy app, yet complain that the HomeBase alarm uses the same tone as a camera intrusion, mention pairing failures, and warn that the battery ships wrapped in plastic.

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.
