Tilt, tamper and freeze

The Fibaro Flood Sensor (HomeKit) lists temperature, tilt, temperature alerts, freeze alerts and tamper alerts. The SwitchBot Water Leak Detector lists none of those. It lists water-leak alerts, a sound and a light. Fibaro lists a sound and a light too. Low-battery alerts are not documented on either sheet.

What owners say

Owners of the Fibaro Flood Sensor (HomeKit) and the SwitchBot Water Leak Detector both like a sensor that makes noise, and both talk about a setup that is short once the right app is open. Fibaro Flood Sensor (HomeKit) owners single out a hideable body, temperature and tilt next to the leak contacts, and Apple Home, and a few had to fix a controller that misread the device type. SwitchBot Water Leak Detector owners single out hub-free Wi-Fi and alerts that caught a leak while they were away, and they complain that without a cable a puddle just beside the contacts can be missed, and that Wi-Fi or HomeKit pairing can take a careful pass at the QR steps.
