Hydra EVSE version 2.4.1

  • WARNING: EEPROM format is incompatible with previous releases, this release will
    reset all the eeprom settings

  • Unit test mode in a standard uno 3 board

  • Display and pin assignments hardware abstractions

  • A lot of redundant code and constants eliminated

    • display duplication
    • symmetrical code duplication
    • timezone library is gone. Funcationality rewritten in more compact way
    • the production versuib removes serial logging and its related strings completely

  • eprom persitence and validation:

    • save/load via one operation as the whole struct
    • added eeprom "magic" signature to validation logic

  • exponentially weighed average online symmarizer with irregular sampling to smooth out the current displays
    (display only; internal analytic is seeing original raw values)

  • experimental: learn and apply RTC calibration with a fast convergent model with embedded Bayesian treatment

  • up to 4 attemtps to restart EVSE charging after a GFI fault separated by 15 minute pause. The
    attempt count is reset by one of the following:

    • EVSE restart
    • EVSE enter into paused mode by short-pushing the button
    • Unplugging both cars thus clearing both states into state A
