Aeotec Water Sensor 7 Pro vs Fibaro Flood Sensor (Z-Wave)

Full Smart Water Leak Sensors comparison in 2026

Updated September 2026
Data from Amazon and official Aeotec and Fibaro sites.
2026 verdict
Two Z-Wave leak sensors, one siren. The Fibaro Flood Sensor (Z-Wave) is the better pick, beeping and flashing on the spot and adding tilt and tamper alerts to its leak, temperature and freeze alerts.

It is also the better reviewed of the two and can run from an optional 12/24V DC supply with its CR123A as backup. The Aeotec Water Sensor 7 Pro is the cheaper one, lasts about 3 years on its ER14250 cell against 2 years, and ships with a sensor cable so the probe can reach a spot the sensor body cannot, but it has no sound or light of its own. Both need a Z-Wave hub, both work with SmartThings and Home Assistant, and both send temperature and freeze alerts. Choose the Fibaro Flood Sensor (Z-Wave) for local alarms and tamper protection, and the Aeotec Water Sensor 7 Pro for a probe on a cable at a lower price.

What the differences mean

Alarm at the sensor

The Fibaro Flood Sensor (Z-Wave) sounds and flashes when it gets wet, so someone nearby hears it even if the hub is busy. The Aeotec Water Sensor 7 Pro has no sound or light and relies on your hub and app.

Probe on a cable

The Aeotec Water Sensor 7 Pro includes a sensor cable, so the body can be mounted dry while the probe sits under a water heater or in a drip pan. The Fibaro Flood Sensor (Z-Wave) detects where it sits.

Tilt and tamper

The Fibaro Flood Sensor (Z-Wave) has a tilt sensor and tamper alerts, so it reports being picked up or moved. The Aeotec Water Sensor 7 Pro has neither.

Power

The Aeotec Water Sensor 7 Pro is rated for about 3 years on one ER14250 cell. The Fibaro Flood Sensor (Z-Wave) is rated for about 2 years on a CR123A but can be wired to 12/24V DC, turning the battery into a backup.

Which one to buy if

What owners say

Owners of both Z-Wave sensors agree they are reliable once paired, and both groups value the temperature reading for freeze warnings. Aeotec Water Sensor 7 Pro owners single out how sensitive the probe is, the flexibility of the cable and smooth Home Assistant and SmartThings automations, but several describe a fiddly pairing on hubs like Hubitat that took resets, and a few saw the probe corrode when left in standing water. Fibaro Flood Sensor (Z-Wave) owners praise pairing in seconds, the tilt and tamper alerts and long battery life, while some found their platform misidentified the sensor, and a handful received scratched units or low batteries.

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.

Frequently Asked Questions

Which is better overall: Aeotec Water Sensor 7 Pro or Fibaro Flood Sensor (Z-Wave)?

The Fibaro Flood Sensor (Z-Wave), for its on-device siren and light, tilt and tamper alerts and optional DC power. The Aeotec Water Sensor 7 Pro is cheaper, lasts longer on its battery and includes a probe cable.

Is the Fibaro Flood Sensor (Z-Wave) a water and temperature sensor?

Yes. The Fibaro Flood Sensor (Z-Wave) detects water and measures temperature, with temperature and freeze alerts, plus tilt sensing. The Aeotec Water Sensor 7 Pro also sends temperature and freeze alerts but has no tilt sensor.

Do they need a Z-Wave hub?

Yes, both. The Aeotec Water Sensor 7 Pro and the Fibaro Flood Sensor (Z-Wave) have no Wi-Fi, Zigbee or Thread and work through a Z-Wave controller, with SmartThings and Home Assistant supported.

Can they sit in standing water?

Neither is documented for it. The Aeotec Water Sensor 7 Pro is rated IP20, and some owners saw its probe corrode in standing water; the weather resistance of the Fibaro Flood Sensor (Z-Wave) is not documented.

Who should buy the Aeotec Water Sensor 7 Pro?

Z-Wave users who want an affordable sensor with a probe on a cable for tight spots, and long battery life, and who get their alerts through the hub.

Who should buy the Fibaro Flood Sensor (Z-Wave)?

Z-Wave users who want a compact sensor that also sounds and flashes locally, reports tilt and tampering, and can run on wired DC power.
