Application changelog

Application 5.1

• Reset RFID on boot

• Disable reservations in PlugAndCharge mode

• Optimize charger shutdown by stopping the active sessions in parallel

• Improve parsing of Wi-Fi networks to work with wider range of Wi-Fi firmwares

• Periodically network interfaces' states as a workaround if an event is missed

• Force all per-phase energy measurements to zero when using MID meter.

Settings

• Increase versions to 10 and 8 for Operations and Power Management

    respectively.

• Add SingleSwipeStop to disable confirmation screen for stopping the

    charging by swiping an RFID card.

• Add VendorLogoTimeout to set timeout for vendor logo on screen saver exit.

• Repurposed IsPaymentMaster to set payment master GUI workflow.

• Fix setting nullable fields (currently only SmartHome.Modbus.CommunicationLostFallbackCurrent).

Charging Profiles

• A default state of charging profiles may now come with factory defaults. It

    is restored on factory reset.

• Add RecurringProfileRandomDelay setting for delaying the start of profiles

    for a random period of up to 30 minutes.

• Add ChargingModeSetting setting to set whether charging profiles are

    respected in Fast mode.

• Add `AllowRemoteProfiles` setting to (dis)allow changing charging profiles

    via OCPP.

• Add RealignProfileZero setting to enable realignment of start of charging

    profile with ID = 0 to Monday 0:00 on every Sunday 4:00 to synchronise

    schedules with daylight saving time switching.

OCPP

• MeterValues

  • Allow sampled data interval as low as 1 second. Message resending is disabled when lower than 5 seconds

Modbus

• Move registers 50 -> 52 and 150 -> 152 to fix overlapping with registers 48 and 148 respectively.

• Only enable ModbusTCP over TLS if a certificate authority is installed.

• Fix showing zeros in most registers when the charging is paused.

• Fix checking whether Modbus connection is active to also acknowledge writes.

 GUI

• Add Increase Log Level in Service Menu.

Web Interface 2.6.6

New features:

• Recurring load schedule management added to Power management configuration

• Under load schedule management weekly recurring profile can be enabled/disabled and edited

• Under load schedule management user can select if charger should allow accepting remote schedules (over OCPP)

• Under load schedule management user can select is load schedules are applied in any charging mode or only smart mode

• On dashboard, while charging, user can check if load schedule has an effect on decreased charging

• While connector in available or preparing state, user can enable start charging in the case that authorization is required. Example: hotel infrastructure operator can remotely enable charging for its guests. User can edit how long wake up logo is show. This is useful when displaying instructions/help to new customers when approaching the charger

Improvements:

• Application will report error if no language or more than 4 languages selected in regional settings

• User can select if DUO charger equipped with credit card payment terminal serves as payment master. If yes, then Pay here button is displayed in the bottom of the screen
