Updated October 2026
Data from Amazon and official Eufy and Fibaro sites.

It also sends general temperature alerts next to freeze warnings, works with SmartThings as well as Home Assistant and can run on an optional 12/24V DC supply with the battery as backup. The Eufy Water and Freeze Sensor is the cheaper and better reviewed of the two and is sealed to IP65, but it needs a Eufy HomeBase and has no sound or light of its own. Both last about 2 years on a CR123 cell and carry 1 year of warranty. Buy the Fibaro Flood Sensor (Z-Wave) for a Z-Wave smart home, and the Eufy Water and Freeze Sensor if a Eufy HomeBase is already on your network.

What the differences mean

Hub it depends on

The Fibaro Flood Sensor (Z-Wave) needs a Z-Wave controller such as SmartThings or a Home Assistant stick. The Eufy Water and Freeze Sensor needs a Eufy HomeBase. Neither connects to Wi-Fi on its own, so the hub you already own is the first filter.

Local alarm

The Fibaro Flood Sensor (Z-Wave) beeps and flashes on the spot when it gets wet. The Eufy Water and Freeze Sensor is silent and relies on the HomeBase alarm and the app.

Extra sensing

Both warn about freezing temperatures. The Fibaro Flood Sensor (Z-Wave) adds general temperature alerts, a tilt sensor and tamper alerts, so it also tells you if someone moves or opens it.

Power and sealing

The Fibaro Flood Sensor (Z-Wave) can be wired to a 12/24V DC supply with the battery as a backup, useful for a permanent install. The Eufy Water and Freeze Sensor is battery only but sealed to IP65, while the Fibaro's weather resistance is not documented.

What owners say

Owners of both sensors describe setup as quick once the right base is in place, a HomeBase for one and a Z-Wave hub for the other. Eufy Water and Freeze Sensor owners single out how sensitive it is, alerting on a couple of drops, and complain that the HomeBase alarm shares the tone of Eufy's camera alarm, that pairing can fail and that the recording schedule can delay alerts. Fibaro Flood Sensor (Z-Wave) owners value the temperature reading and freeze alerts, the tilt and tamper alerts and a battery that lasts, while a few found their hub misidentified the sensor and needed extra configuration, and some received units with scratches or a low battery.
