Release v3.10.1

SmartEVSE v3.10.1 Release Notes

Overview

This release includes bug fixes and improvements to current regulation and pilot control logic.

BugFixes

• Fixed pilot disconnection behavior (#314) - Removed pilot voltage check when disconnecting, as this could lead to failing to start charging. Also the pilot is no longer disconnected when switching to PAUSE or OFF modes.

• Fixed default entity ID format (#313) - Corrected the default_entity_id format in network configuration to ensure proper Home Assistant integration.

• Improved current up-regulation when using CAPACITY setting (#306).

Documentation

• Updated README with SmartEVSE mobile app details and instructions for app integration.

New Features

SmartEVSE App Server Connection

• EVMeter.Energy = Wh
• EVMeter.EnergyCharged = Wh
• EVMeter.Import_active_energy = Wh
• EVMeter.Export_active_energy = Wh
• MainsMeter.Import_active_energy = Wh
• MainsMeter.Export_active_energy = Wh

BugFixes

• add input validation for SSID and password fields
• allow special characters in password strings. fixes #287
• improve Auto 1P/3P switching logic
• show additional Contact 2 information on LCD while in setup menu.
• Add custom OCPP key (ConfigureMaxCurrent) to configure MaxCurrent of the controller
• implement efuse serial number fallback logic
• Erase RFID cards when performing a /erasesettings
• Refactor event handling for reboot and help links Author: @kozmoz
• Improve mode button responsiveness #283 Author: @kozmoz
• replace blocking getLocalTime(), with non-blocking code. fixes SmartEVSE#110

Thanks @dingo35, kozmoz, hmmbob for their contributions.

Release v3.9.2

Changes:

• fix Slave sticks at 6A when Master not charging in Solar mode
• improved phase switching for enableC2=AUTO, so we switch back to single phase earlier, which improves use of solar power
• initalize Nr_Of_Phases_Charging to prevent unnecessary phase switching after boot
• only correct BatteryCurrent on first phase when EnableC2 is set to
• we got rid of ESPtouch app, now we setup wifi via a rudimentary AP instead of via SmartConfig
• we now have to reboot after having solved an RCM error

Release v3.9.1

Changes:

• BREAKING change: MQTT publish Cable Lock values according to announcement, with 0 and 1
  The Cable Lock was announcing values 0 and 1, but was actually publishing "Disabled" and "Enabled". It now publishes "0" and "1" conform its announcement, but this change can be breaking for scripts in HomeAssistant and other MQTT clients.
• fix only charging 6A on Master/Slave in Solar mode with C2=AUTO on master
• add Nr_Of_Phases_Charging to /settings
• MQTT added /Set/EnableC2
• MQTT add announce for NrOfPhases
• MQTT always send CustomButton. (#253)
  Added CustomButtonPressTime in milliseconds. This way you can see how long the button was pressed to add your own custom actions.
• Update ocpp.md with SteVe user experience (#256)

Release v3.9.0

This version finally supports switching from single phase (1P) to three phase (3P) and back in Solar Mode, depending on how much sun is available, provided you have a second contactor (C2) installed and wired according to our instructions.

Changes:

• introduce switching from 3P -> 1P -> 3P when C2=AUTO, many thx to Rob040
• publish NrOfPhases via MQTT
• Added direct MQTT message when custom button is pressed. (#242)
• only allow C2 = AUTO for non-slaves
• in Smart mode with C2 = Auto, switch to 3P

Release v3.8.5

This is a bugfix release.

Changes:

• in Solar mode, some cars didn't wake up in the morning; also OFF mode was ignored sometimes, including the one when delayed charging

Release v3.8.4

This release is modest on changes since we aim to make this the stable release soon.

Changes:

• publish RFIDLastRead to MQTT also in old/new reader format
• fix round errors in power and energy output in REST API, thx to Rob040
• publish [Mains|EV]meter [Im|Ex]port Active Energy via MQTT
• add more solar controls to dashboard
• better resume of charging after power interruption
• add HELP button on dashboard
• update docs on OCPP backend providers

Release v3.8.3

This is a bugfix release that fixes OCPP operation that was disturbed in v3.8.2 .
