What owners say

Owners of both sensors report leaks caught before real damage. SwitchBot Water Leak Detector owners single out a setup of a few minutes with no hub and a sensor that fired while they were travelling; they warn that the unit has to sit exactly where water arrives, that HomeKit pairing can be fiddly and that the alarm is hard to hear from other rooms. Fibaro Flood Sensor (Z-Wave) owners describe pairing in seconds on a Z-Wave hub, and value the temperature sensor for freeze risk and the tilt and tamper alerts; their complaints are platforms that misidentify it, no probe cable in the box and the odd unit arriving with a low battery.
