Changelog

• 3.1.0:
  • NEW FEATURE: Add support for up to 3 "Profiles" which can be used to quickly switch between different brew settings (eg. when different beans are used).
    • An individual profile comprises of following settings:
      • Brew Temperature / setPoint
      • Brew Time
      • Preinfusion time and pause
      • Coldstart Temperature / startTemp
    • Profiles can be selected by any means, eg mqtt/blynk/menu/.. . The variable for this is "profile".
    • The selected profile is also shown on the display, see new setting ENABLE_PROFILE_STATUS.
    • ATTENTION: Following variable names has changed and therefore any mqtt dashboards and tools have to be adapted (eg IotMQTT/Grafana/nodered):
      • setPoint -> activeSetPoint
      • brewtime -> activeBrewTime
      • starttemp -> activeStartTemp
      • preinfusion -> activePreinfusion
      • preinfusionpause -> activePreinfusionPause
      • Hint: Changing the value of any of variables (eg using mqtt/blynk) will update the respective setting of the currently activated profile.
