Flume 2 Smart Water Monitor vs SwitchBot Water Leak Detector

The SwitchBot Water Leak Detector wins overall, with a lower price, a higher owner rating, a built-in 100dB alarm and light, and native support for Google Home, Alexa, Apple HomeKit and Samsung SmartThings. The Flume 2 Smart Water Monitor answers back with a wider range of tracked alert types, since it also flags low battery status alongside a leak.

Where they watch for water. The SwitchBot Water Leak Detector is a point sensor that has to sit exactly where a leak would occur, since it has no extendable cable. The Flume 2 Smart Water Monitor instead reads the home's whole water meter, so it catches leaks anywhere on the property rather than only at one fixed spot.

No. It connects directly over 2.4GHz Wi-Fi or Bluetooth to the SwitchBot app and from there to Google Home, Alexa, Apple HomeKit or Samsung SmartThings. The Flume 2 Smart Water Monitor also skips a traditional smart home hub, but it does need the Wi-Fi bridge it ships with to relay readings from the meter sensor to the app.

The SwitchBot Water Leak Detector does. It carries its own 100dB on-device alarm and alert light that fire at the sensor itself. The Flume 2 Smart Water Monitor has no onboard siren; every alert, including its low battery warning, arrives through the app instead.

Buy it for affordable, no-hub leak detection at a single known trouble spot, a water heater, washing machine or basement floor, especially in a home already running Alexa, Google Home, Apple HomeKit or Samsung SmartThings.

Choose it if catching a leak anywhere on the property, including ones that never reach a floor sensor, matters more than the lower price and local alarm of a point sensor like the SwitchBot Water Leak Detector.
