Fibaro Flood Sensor (HomeKit) vs Shelly Flood

The Fibaro Flood Sensor (HomeKit) wins overall on rating, battery life, and sensor breadth, including tilt and tamper detection. The Shelly Flood remains the more affordable option with wider integrations and a longer warranty.

Sensing depth versus ecosystem reach. The Fibaro packs in tilt and tamper alerts alongside water and temperature sensing, while the Shelly Flood keeps to water and temperature but plugs into Google Home, Alexa, and SmartThings.

The Fibaro Flood Sensor (HomeKit) does, adding a tilt sensor with tamper alerts on top of water-leak and temperature sensing, a category the Shelly Flood doesn't cover.

The Fibaro Flood Sensor (HomeKit) does, with both an on-device alert sound and light. The Shelly Flood has neither, relying entirely on app and hub notifications.

Choose it if you want the better-rated, longer-lasting sensor with tilt and tamper detection plus a local alarm, especially in an Apple Home setup.

Pick it if you want the cheaper option with a longer warranty and need Google Home, Alexa, or SmartThings support rather than HomeKit.
