# Flume 2

*Flume*

> The Flume 2 is a whole-home water monitor: a battery-powered sensor straps onto the water meter and sends readings by 915 MHz radio to a Flume Bridge, which connects to 2.4 GHz Wi-Fi and the Flume app. It suits Google Home, Alexa and Home Assistant users through an integration (the maker's hub). It does not support HomeKit and SmartThings.
