Arlo All-in-One Sensor vs Fibaro Flood Sensor (Z-Wave) comparison

Updated July 2026

Data from Amazon and official Arlo and Fibaro sites.

2026 verdict

The Fibaro Flood Sensor (Z-Wave) comes out on top against the Arlo All-in-One Sensor for this water leak sensor comparison, carrying a higher owner rating and adding both an on-device alert sound and light plus tamper alerts, none of which the Arlo sensor supports. The Arlo All-in-One Sensor answers with a lower price and a wider integrations list through Google Home and Alexa, since the Fibaro sensor has no direct connection to either and instead relies on a Z-Wave hub. Both sensors combine water-leak detection with temperature and tilt sensing in a single unit. For buyers running a Z-Wave hub or Home Assistant who want a local alarm and tamper detection, the Fibaro Flood Sensor (Z-Wave) is the stronger pick, while Google Home or Alexa households wanting a cheaper multi-sensor should choose the Arlo All-in-One Sensor.
