It sounds a 90 dB alarm and lights up on the sensor, sends low battery alerts and works with Google Home, with partial Home Assistant support. The Fibaro Flood Sensor (Z-Wave) does more sensing: a temperature sensor with general and freeze alerts, a tilt sensor and tamper alerts, plus its own siren and light and an optional 12/24V DC supply, and it works with SmartThings and Home Assistant through a Z-Wave hub. Both need a hub, a Tapo Hub for one and a Z-Wave controller for the other. Buy the Tapo T300 for a simple, long-lived leak alarm in a Tapo home, and the Fibaro Flood Sensor (Z-Wave) for freeze and tamper coverage on Z-Wave.

What the differences mean

What it senses

The Fibaro Flood Sensor (Z-Wave) adds a temperature sensor with general and freeze alerts, plus tilt sensing and tamper alerts. The Tapo T300 detects water only, so it will not warn you about a pipe about to freeze.

Hub and platforms

The Tapo T300 needs a Tapo Hub and works with Google Home, with partial Home Assistant support. The Fibaro Flood Sensor (Z-Wave) needs a Z-Wave controller and works with SmartThings and Home Assistant.

Battery and power

The Tapo T300 is rated for about 3 years on two AAA batteries and sends low battery alerts. The Fibaro Flood Sensor (Z-Wave) gets about 2 years from a CR123A but can be wired to 12/24V DC, keeping the battery as a backup.

Sealing

The Tapo T300 is sealed to IP67, so it can sit in a puddle. The weather resistance of the Fibaro Flood Sensor (Z-Wave) is not documented.

What owners say

Owners of both say pairing is quick once the right hub is in place and that the local alarm does its job. Tapo T300 owners single out months of stable connection, a loud alarm with instant phone alerts and detection from both the top and the bottom of the unit, while complaining that the hub requirement was not obvious, that sensor and hub models can mismatch outside the US, and that the small top sensor can miss an off-centre drip. Fibaro Flood Sensor (Z-Wave) owners praise the temperature reading for freeze warnings, the tilt and tamper alerts and long battery life, though some found their hub misidentified it and a few received units with scratches or low batteries.

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.
