2026 verdict
An alarm on the sensor itself and tamper sensing put the Fibaro Flood Sensor (HomeKit) ahead of the Aeotec Water Sensor 7 Pro in this water leak sensor comparison.
The Fibaro sounds and flashes where the leak is, detects tilt with tamper alerts, measures temperature for freeze warnings, pairs with Apple Home over Bluetooth and works with Home Assistant, and it can run from a 12/24V DC supply. The Aeotec Water Sensor 7 Pro is the lower priced option for a Z-Wave home on SmartThings or Home Assistant, with a probe on a cable for a drain pan, the same temperature and freeze alerts, and an ER14250 battery rated for 3 years against 2 on the Fibaro's CR123A, but it is silent on its own. Neither works with Alexa, Google Home or Matter. Choose the Fibaro Flood Sensor (HomeKit) for Apple Home, and the Aeotec Water Sensor 7 Pro if your hub speaks Z-Wave.

What the differences mean
Radio and platform
The Aeotec Water Sensor 7 Pro is Z-Wave and works with SmartThings and Home Assistant through a Z-Wave hub. The Fibaro Flood Sensor (HomeKit) is Bluetooth and works with Apple Home through an Apple TV, HomePod or iPad, and with Home Assistant. Your hub decides this one.
Local alarm
The Fibaro Flood Sensor (HomeKit) sounds an alarm and flashes a light on the device, so someone nearby hears it right away. The Aeotec Water Sensor 7 Pro has neither and warns only through your hub.
Tamper and tilt
Only the Fibaro detects tilt and sends tamper alerts, so it knows if a pet or a person moves it. Both measure temperature and send freeze alerts.
Probe and power
The Aeotec Water Sensor 7 Pro includes a probe on a cable and runs 3 years on an ER14250. The Fibaro detects through its body, runs 2 years on a CR123A, and can be wired to a 12/24V DC supply with the battery as backup.
Which one to buy if
- your home runs on Apple Home
The Fibaro Flood Sensor (HomeKit) pairs directly into the Home app; the Aeotec has no Apple Home support.
- your hub speaks Z-Wave
The Aeotec Water Sensor 7 Pro joins your Z-Wave mesh on SmartThings or Home Assistant.
- you want to hear the alarm without a phone
Only the Fibaro sounds and lights up on the sensor.
- the leak point is a narrow drain pan
The Aeotec's probe on a cable reaches where the Fibaro body would not fit.

What owners say
Owners of both sensors report leaks caught early, use the temperature reading as a freeze warning, and describe batteries that last. Both groups also hit connection trouble, in different forms. Aeotec Water Sensor 7 Pro owners praise the probe on its cable and smooth automations on Home Assistant and SmartThings, but several needed factory resets before a Z-Wave hub recognised it, and a few saw the probe corrode in a constantly damp spot. Fibaro Flood Sensor (HomeKit) owners like the onboard alarm and light, the tilt and tamper sensing and quick pairing into the Home app, yet in larger homes some needed another Apple TV to reach it over Bluetooth, a few had it drop offline, and some wanted a way to silence the alarm remotely.
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.
