Firmware updates for Zaptec Pro models

This update adds support for integration with Tibber.

In version 3 of the charging station firmware we have made some large architectural changes to make the firmware more stable in general.
Most of these changes will not be easily noticeable, but we can mention some changes that you might notice with this firmware update:

• An energy meter has been added. The value of the meter is shown in the ZAPTEC Portal, and will start counting from 0 kWh when firmware version 3 is installed.
  Note that the energy meter in ZapCharger Pro and Home is not calibrated according to MID, like the ZAPTEC PRO.
  The energy meter in ZAPTEC PRO starts at 0 kWh when it is produced.
• Charge cards that follow the ISO 15693-standard are now also supported (Only ISO 14443 Type A-cards was supported previously)
• The charging station will indicate when it is waiting for authorization from the cloud by blinking yellow slightly faster after authenticating with a charge card, or the ZAPTEC app.
• Authentication has been improved to better avoid situations where the charging station and app is "hanging" when attempting to start charging.
• In some fault situations, the charging station will attempt to restart charging after a delay, instead of "giving up" the first time a fault occurs. (For example when the RCD trips, or the car draws too much current)
• The WiFi-network re-connection handling has been improved.
• Reporting of charging sessions to the ZAPTEC Portal has been made more robust.

• This update rolls back the changes in firmware 2.8.0.3, as the issue has been solved on the server-side.

• This update fixes issues some charging stations had with connecting with the ZAPTEC Portal.

• This update contains no changes for charging stations that have already been produced

• Support for three phase charging on IT grids for charging stations in a system
• Support for three phase charging on IT grids for Audi e-tron and newer models of Volkswagen e-Golf
• Improved handling of situations where the car draws more current than it is supposed to.

• Fixed a bug where connecting to the charging station via the app was not possible 5 minutes after starting up if the charging station was offline
• Fixed some bugs related to charge session handling over OCPP
• Improved the communication handling for some cars (e.g. VW eUp)

• This update contains no changes for charging stations that have already been produced.

• Support for three-phase charging on IT-grids (currently only in standalone mode)
• The name assigned to the charging station in ZAPTEC PORTAL is now displayed in the app when connecting to a charging station over Bluetooth (This is currently only supported on charging stations produced after February 12th, 2019)
• When a connection check of the electrical grid is performed using the app, the jumper required for IT-grids are now verified to be installed.
• Fixed a bug where authentication took a very long time to complete when the time between the user connecting the car and authenticating themselves was very long.

• Adjusted charging behaviour to work better with the Tesla Model 3 “Sentry Mode” feature
• Fixed a bug where the status indicator brightness setting in the app and portal would reset back to 50%
• Some early production ZapCharger Smart units will revert back to using green (instead of white) status indicator when no car is connected
• Other minor bugfixes.

• The process of updating the charging stations firmware has been improved. The installation is now faster, and the download is more robust on bad internet connections.
• Support for allowing any charge cards to charge while the charging station is offline with internal authentication enabled.
• Fixed a bug where the same user only could authenticate once per offline period
• Fixed a bug when reporting some offline sessions
• Fixed a bug that caused the charging station to restart in some situations
• Support for ZAPTEC Home.

• Charging stations with firmware version lower than 2.5.0.7 will first update to this version, then automatically update to the latest available version after a short while.

• If native authentication is used, only authorized users and charging tokens will be able to charge while the charging station is offline
• If a charging station is offline, the charging indicator will turn off briefly at least once every minute to indicate that it is offline
• When a charging station is disabled in ZapCloud, the charging indicator will be turned off and no charging will be allowed until it is re-activated in the cloud (the charging station will not be re-activated until it is able to connect to ZapCloud). The charging indicator will flash red with low brightness every 30 seconds to indicate that it is disabled.
• Other minor bugfixes and improvements.

• Some issues with preconditioning and delayed charge start in some cars has been fixed
• If internal authentication is activated on the installation, charging can now be stopped by scanning the same charging token that started the charging session.
• The icon for communication mode in ZapCloud now indicates the charging stations actual communication mode, not the configured mode
• The charging station will now detect when it loses its network connection faster. An issue where the charging station could allow the car to charge with too much current for a brief amount of time after losing its network connection has also been fixed.
• A bug where the app would not show any available Wi-Fi access points if an access point with no name was found has been fixed
• If a firmware update is started using the app, the update now start immediately as long as no car is connected
• Several improvements and stability fixes related to the communication with ZapCloud
• Stability fixes for the Wi-Fi connection.

• This update only includes changes that apply during the production testing of newly produced units.

• Minor stability fixes and small bugfixes to the Bluetooth interface
