It adds temperature and tilt to water detection, sounds a local alarm with a light, and works natively with Apple Home and Home Assistant. The Aqara Water Leak Sensor T1 stays the better pick on price and on rating, and it is the tougher of the two: IP67 sealed, able to trigger at just 0.5 mm of water, with a Zigbee path to Apple Home, Google Home and Matter through an Aqara hub plus direct SmartThings support. The Fibaro Flood Sensor (HomeKit) depends on Bluetooth range to a HomeKit hub. Pick the Fibaro Flood Sensor (HomeKit) for richer sensing and a local alarm, and the Aqara Water Leak Sensor T1 for a small, fully waterproof puck in a Zigbee home.

What the differences mean

Sensing

The Fibaro Flood Sensor (HomeKit) detects water, temperature and tilt, and raises tamper alerts if it is moved. The Aqara Water Leak Sensor T1 is a water-only sensor, with no temperature, freeze or tilt channel.

Hub and range

The Aqara Water Leak Sensor T1 needs a Zigbee hub and can sit far from it over a Zigbee mesh. The Fibaro Flood Sensor (HomeKit) pairs over Bluetooth, so its reach depends on how close your Apple TV, HomePod or iPad is.

Local alarm

The Fibaro Flood Sensor (HomeKit) has a sound and a light on the unit. The Aqara Water Leak Sensor T1 has neither, so the alarm is produced by the hub or by another device in your automation.

Integrations

The Aqara Water Leak Sensor T1 reaches Apple Home, Google Home and Matter through an Aqara hub, pairs with a SmartThings hub directly and works with Home Assistant. The Fibaro Flood Sensor (HomeKit) is native to Apple Home and also supports Home Assistant.

Sealing and trigger

The Aqara Water Leak Sensor T1 is IP67 and reacts at 0.5 mm of water, so it survives a flood and catches a slow drip early. The Fibaro Flood Sensor (HomeKit) publishes no IP rating and reacts where its contacts sit.

What owners say

The reviews behind the Fibaro Flood Sensor (HomeKit) describe a sensor owners trust to catch the leak before it spreads, with the on-device sound and light and the HomeKit push all firing fast. They single out the temperature channel as useful for freeze automations and the tilt sensor as a quiet tamper warning. Setup through the Fibaro app and the Home app is called quick, and several owners report the CR123A still near full after a year. The friction is Bluetooth: in larger or concrete-heavy homes a second Apple TV is needed as a repeater, a few units dropped offline, and there is no remote mute, so the alarm keeps sounding until the contacts dry.
