United StatesFlume is an American company founded after California's 2014 drought to make household water use visible. Its single product line is the Flume smart water monitor, a strap-on sensor that reads the existing residential water meter magnetically and relays usage to a Wi-Fi bridge indoors, so it needs no plumbing work. The app reports real-time consumption by fixture, sets budgets, and sends leak alerts for both catastrophic bursts and slow drips.

YoLink uses its own long-range LoRa wireless technology to connect smart home sensors and devices across large properties where Wi-Fi and Zigbee struggle. Its catalog includes leak sensors, door sensors, sirens, valve controllers and smart plugs, managed through the YoLink app and hub. YoLink is popular for whole-property monitoring thanks to its long wireless range.
