The Arlo All-in-One Sensor answers with a lower price and a higher owner rating, plus its own broader built-in sensing that covers water, temperature, and tilt in one device. The Fibaro Flood Sensor (HomeKit) also senses temperature and tilt, pairing them with tamper alerts and native Apple HomeKit support via Bluetooth, whereas the Arlo sensor works through Google Home and Alexa instead. Buyers who want native HomeKit connectivity and a genuinely loud local alarm should pick the Fibaro Flood Sensor (HomeKit), while those chasing a cheaper, higher-rated sensor with Google Home or Alexa support should choose the Arlo All-in-One Sensor.
