It adds temperature and tilt to leak detection, carries the stronger owner rating and works with Apple Home and Home Assistant without a bridge. The Resideo L1 WiFi Water Leak and Freeze Detector counters with a two-year warranty, a 5 ft sensing cable that extends to 500 ft for watching a whole pipe run, a 100 dBA buzzer and temperature and humidity alerts, and it needs no hub at all. The Fibaro Flood Sensor (HomeKit) depends on Bluetooth range to a HomeKit hub and, several owners note, cannot be silenced remotely. Pick the Fibaro Flood Sensor (HomeKit) for an Apple Home that wants richer sensing, and the Resideo L1 WiFi Water Leak and Freeze Detector when a cable and hub-free Wi-Fi matter more.

What the differences mean

Hub or no hub

The Resideo L1 WiFi Water Leak and Freeze Detector joins 2.4 GHz Wi-Fi on its own and needs no hub, while the Fibaro Flood Sensor (HomeKit) uses Bluetooth to an Apple TV, HomePod or iPad acting as a HomeKit hub, so its range depends on where that hub is.

Sensing

The Fibaro Flood Sensor (HomeKit) adds a tilt sensor and tamper alerts on top of water and temperature. The Resideo L1 WiFi Water Leak and Freeze Detector tracks temperature and humidity and alerts when either leaves the range you set, which is useful for a whole room.

Alarm control

Both sound an alarm and blink a light at the unit. The Resideo L1 WiFi Water Leak and Freeze Detector lets you mute its 100 dBA buzzer in the app or on the device, while the Fibaro Flood Sensor (HomeKit) has no remote mute, so several owners report it keeps sounding until the contacts dry.

Sensing cable

The Resideo L1 WiFi Water Leak and Freeze Detector includes a 5 ft cable that senses along its full length and extends to 500 ft with accessories. The Fibaro Flood Sensor (HomeKit) is a puck that detects water only where its contacts sit.

Ecosystem

The Fibaro Flood Sensor (HomeKit) is at home in Apple Home and also works with Home Assistant. The Resideo L1 WiFi Water Leak and Freeze Detector lives inside the First Alert and Resideo apps, with no Alexa, Google Home, Apple Home, SmartThings or Matter path.

Warranty

The Resideo L1 WiFi Water Leak and Freeze Detector carries a two-year warranty against one year on the Fibaro Flood Sensor (HomeKit). Neither figure changes with a sale, so it is a fair tiebreaker between two otherwise close devices.

What owners say

What owners of the Fibaro Flood Sensor (HomeKit) report is mostly peace of mind: it caught a real leak, a failed sump pump or a slow drip, and both the HomeKit push and the on-device sound and light fired fast. They single out the temperature sensor as a bonus for freeze automations and the tilt sensor as a tamper layer. Setup through the Fibaro app and the Home app is generally called fast, and several owners report the CR123A still near full after a year. The complaints are about range and warning. Bluetooth means a large or thick-walled home may need another Apple TV as a repeater, a few units dropped offline, and there is no way to silence the alarm remotely until the contacts dry.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
