V3.2.0

• Beta Tesla API support (no GUI support yet) #67

• EEPROM config is now stored in JSON format

• Realtime VRMS via MQTT for improve solar PV divert calculation. e.g from emonPi emon/emonpi/vrms

  • Note: this feature will in the future be used to improve the OpenEVSE energy calculation, this will require a OpenEVSE controller firmware update (as yet unreleased)

• Significant update to solar PV divert functionality: Issue #54 PR #76

  • Eco Mode is now pervasive between charging sessions
  • PV divert ("Eco Mode") will now pause charging once solar PV / Grid IE drops below the minimum current (6A) and will resume when more power is available.
  • Charge current calculation is now processed via a smoothing algorithm to avoid any stopping/starting charging unnecessarily
  • Improved user display to communicate charging state e.g "Charging from Solar", "Waiting for Solar" etc
  • Timer charge functions as an overnight boost timer'. If EcoMode is left enabled and a timer is set e.g overnight off peak period, the EV will charge at full current for the duration of the timed charge.
  • Enable 'advanced' mode to adjust smoothing and minimum charge time settings:
