This is my 'homebrew' version of the brew-by-weight functionality that comes with a Linea Mini plus the LaMarzocco + Acaia proprietary scales. Given I have a Micra, this functionality isn't supported out of the box.
It uses:
- ESPHome to connect to my Acaia Lunar scales over Bluetooth using a forked version of https://github.com/open-lcc/esphome-acaia-component (my forked version fixes the flow calculation)
- The LaMarzocco custom HomeAssistant integration: https://github.com/zweckj/lamarzocco
