The good news: Flume works with many water utilities, which gives it a steady business beyond individual buyers.
The bad news: Flume is small, and everything it does depends on its cloud. If it shut down, the sensor would stop being useful.
If you own Flume
- Export your water use history from time to time.
- Know where your main water shutoff is, since Flume only alerts you and cannot close the water itself.
