V7.1.3.EU

• Autodetection of openevse controller hardware V5.5+, PD7 is tied high on 5.5 Controllers and LOW (by default) on pre v5 #define OEV6. Backwards compatible with older hardware.

V7.1.2.EU

Required for WiFi V4.x

V7.0.2.EU

RAPI V5.1.3

RAPI version 5 - Requires ESP32 WiFi with firmware V3.0.3 or greater or ESP8266 WiFi Firmware V2.9.0 or greater

• get rid of LoadThresholds()/g_DefaultThreshData to save space
  -> fixes a bug that crept in to DoPost() when hardcoded value changed to
  if (reading >= m_ThreshData.m_ThreshAB) {
  -> was testing against m_ThreshData before initializing it, so the code was executing, even when an EV connected
• fix compiler warning in SetupMenu::Select()

V7.0.1.EU

RAPI V5.1.3

• send $AT during sleep if EV connect/disconnect

D6.2.0 20200327 SCL

• fix 1 sec delay in showing current when charging starts
• make space by taking stuff out of button menu that is still accessible via WiFi NOSETUP_MENU 9c487b5
• add RAPI $FF B to enable/disable front button
• fix bug in $AT.. was supposed to send GetCurrentCapacity(), not GetMaxCurrentCapacity()
• send $AT during sleep for EV connect/disconnect faf39ff
• change $GC .. new 4th returned parameter is max set current capacity 68f362c
• bump RAPIVER to 5.1.0.
  -> n.b. shouldn't really be using RAPIVER.. should just test for working
  commands and # returned parameters

V6.1.3.EU

Release tag v6.3.1 was mistakenly used, actual version number is v6.1.3

RAPI version 5.0.0 - Requires ESP32 WiFi with firmware V3.0.3 or greater or ESP8266 WiFi Firmware V2.9.0 or greater

• change $GS to return state(hex) elapsed(dec) pilotstate(hex)
• $AB async notification sent at boot
• $AT replaces $ST async notification
• $GS has new extra parameters, and first parameter, state, is now HEX instead of DEC, for consistency with $AT
• Sequence ID always enabled
• $FF command always enabled, deprecating old redundant commands
• $WF enabled only if RAPI_WF defined (Request client WiFi mode)
• get rid of RAPI_RESPONSE_CHK define.. always enabled
• added ECVF_UI_IN_MENU... flag is set/unset when in/out of UI menus..$AT is sent on transition

Auth Lock

• if AUTH_LOCK != 0 or using hardware lock pin, always lock automatically in State A
• display auth lock status on LCD in disabled & sleeping states

Bug Fixes

• for consistency/safety sake, force reboot after exiting Setup menu
• fix bug in relay opening delay code for SLEEP state - wasn't reading/comparing charging current correctly.. was always reading too low, so would instantly open the contactor lincomatic/open_evse@21cfccd
• change SLEEP delay threshold current from 3A -> 1A
• update EVSE status after receiving $S4 command (set auth lock)
• Fix negative temperature display
• Fix lifetime total KWh total

Other

• Add HEARTBEAT_SUPERVISION lincomatic#109
• Heartbeat Supervision. $SY , $GY as in SY heartbeatinterval hearbeatcurrentlimit
• If you do not send open_evse a heartbeat more frequently than every (uint16_t)heartbeatinterval seconds then open_evse will reduce system ampacity to (uint8_t)hearbeatcurrentlimit amperes
• Bring PlatformIO inline with Arduino build lincomatic#108
• Add language pack support lincomatic#59

V5.1.0.EU

• Change session time & charge limits to be absolute instead of extending the current session. e.g. already charged 2kWh.. set limit to 3kWh ... stop @ 3kWh instead of 5kWh

V5.0.1.EU

• Fix overcurrent detection lincomatic#95

V5.0.0.EU

• Fix issue where Start/Stop button will not work when charging timer is active OpenEVSE/ESP8266_WiFi_v2.x#184. Add new $F1 RAPI API to simulate a front button press. lincomatic#88
• Don't let $SC raise ampacity with V during over temperature event 2f84f96 17188f5
• Don't let $SC V increase ampacity above PP ampacity. Fixes lincomatic#90 with 739ac3f
• Overcurrent cutout implemented. If EV draws more current than the pilot setting charging will hard stop. Fixes lincomatic#87 with lincomatic@60b5083
• Don't allow volatile current capacity > EEPROM value lincomatic@ac5dbb0
• don't allow SetCurrentCapacity() above PP max lincomatic@1c51eea

Full change log:

20180523 SCL
- when RTC not defined, g++ bug pops out:
	open_evse:2384: error: unable to find a register to spill in class 'NO_REGS'
  -> add GPPBUGKLUDGE
	
D5.0.0 20180518 SCL
- implement $F1 RAPI command to simulate front panel short press
- SAFETY: don't allow $SC to raise current capacity during over temperature event
- SAFETY: SetCurrentCapacity() -> when nosave set, don't allow current capacity to be
	raised above EEPROM value
	-> don't allow $SC with V to raise current capacity above value in EEPROM
	-> don't allow PP to set current capacity higher than EEPROM
- PP code cleanup
- don't allow SetCurrentCapacity() to go above PP value
- implement over current protection. if OVERCURRENT_THRESHOLD is set,
	then if EV draws >= OVERCURRENT_THRESHOLD amps for >=
	OVERCURRENT_TIMEOUT ms -> hard fault

4.13.0.EU

• revert change from D4.12.0: delay timer would always wait for EV finish charging before ending.
  -> timer will go to sleep at end of specified time window unless charge or time limit set -> charge or time limit will still override timer end. Fixes lincomatic#85
• cleanup of time/charge limit zeroing code: fix $ST bug couldn't set with all leading zeros lincomatic@03a689c
