Description
The WaterFlowKit is an ESPHome-based water flow monitor for supported pulse-based flow sensors. It measures real-time flow rate, total water consumption, and water temperature, and also includes onboard temperature and humidity sensing with the HDC1080.
It is designed for fully local use with ESPHome and Home Assistant, with onboarding through captive portal, Improv BLE, or Improv Serial where supported, and supports HTTP OTA firmware updates.
