Aeotec Water Sensor 7 Pro vs Fibaro Flood Sensor (HomeKit) comparison

Updated June 2026

Data from Amazon and official Aeotec and Fibaro sites.

2026 verdict

The Fibaro Flood Sensor (HomeKit) wins this water leak sensor comparison on breadth of sensing and local alerting, packing water, temperature and tilt detection with tamper alerts plus an on-device alert sound and light, all at a lower price than the Aeotec. It pairs natively with Apple Home over Bluetooth, no separate Z-Wave or Zigbee bridge needed. The Aeotec Water Sensor 7 Pro is still the tougher, longer-running unit: it holds a higher owner rating, an IP20-rated body versus the unrated Fibaro, and a 3-year battery against the Fibaro's 2, along with an included sensor cable for hard-to-reach leaks. Choose the Fibaro Flood Sensor (HomeKit) for a cheaper, HomeKit-native sensor with tilt, tamper and an onboard alarm; pick the Aeotec Water Sensor 7 Pro for a Z-Wave sensor with a longer battery and a probe cable in a SmartThings or Home Assistant setup.

Frequently Asked Questions

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

The Fibaro Flood Sensor (HomeKit) wins overall on price, added tilt and tamper detection, and an onboard alert sound and light, with native HomeKit support. The Aeotec Water Sensor 7 Pro counters with a higher rating and a longer 3-year battery on Z-Wave.

What is the biggest difference between these two sensors?

Ecosystem and sensing mix. The Fibaro Flood Sensor (HomeKit) is a Bluetooth HomeKit device with tilt, tamper and an onboard siren, while the Aeotec Water Sensor 7 Pro is a Z-Wave sensor with a longer battery and an included sensor cable.

Which one has an onboard alarm?

The Fibaro Flood Sensor (HomeKit) has an on-device alert sound and light. The Aeotec Water Sensor 7 Pro has no onboard siren, so alerts route through your Z-Wave hub or app.

Which sensor detects tilt or tampering?

Only the Fibaro Flood Sensor (HomeKit) does, adding a tilt sensor with tamper alerts on top of water and temperature sensing. The Aeotec Water Sensor 7 Pro has no tilt or tamper detection.

Who should buy the Fibaro Flood Sensor (HomeKit)?

Buy it if you run Apple Home and want a cheaper sensor with water, temperature and tilt sensing, tamper alerts, and a built-in alarm, with no separate bridge needed.

Who should buy the Aeotec Water Sensor 7 Pro?

Choose it if you run a Z-Wave hub with SmartThings or Home Assistant and want a longer battery life and an included sensor cable.
