  • Implement SMA Sunny Tripower PV Inverter (#1154)

  • Implement OCPP-Server & more for electric vehicle charging (#1142) Thanks @sebastianasen - this is huge!

    • Uses ChargeTimeEU OCPP server implementation: https://github.com/ChargeTimeEU/Java-OCA-OCPP
    • Start implementation of electric vehicle charging stations by
      • ABL
      • IES Keywatt
    • Numerous improvements on electric vehicle charging algorithms

  • Update Channel methods (#1165).

    • Update methods to access Channels as discussed in #1046 and started in #1099. This avoids calls to setNextValue() and setNextWriteValue() and should make the framework much more understandable and lower the learning curve.

    • Each Read-Channel of a Nature Interface gets following methods: (example for a Channel NAME of type Integer)

      • IntegerReadChannel getNameChannel()
      • Integer getName()
      • _setName(Integer value)
      • _setName(int value)

    • Write-Channels also get a method

      • setName(Integer value) that internally calls the setNextWriteValue() method

  • Fix for Soltaro Cluster Version B 395e563

  • Fix for Socomec Diris A14 0a63657

  • Update for Carlo Gavazzi documentation f67c2c4

  • Update Java dependencies #1149, #1166, #1168, #1170, #1171

UI

  • UI: add status component for each edge (#1162)
    • with right restrictions (at least admin)
  • UI: add feature to rename components in 'Anlagenprofil' (#1163)
    • UI: rename components in 'Anlagenprofil' with restriction (at least: owner)
  • Update UI dependencies b72256e

  • Improve logging c875791
    • start pax logging api as early as possible
    • reduce default log level to INFO
    • move logging configuration to DefaultConfigurationWorker
  • Improvements in EdgeConfig handling (#1074) (#1076)
    • remove "isEnabled"; it's already covered by the 'enabled' property
    • improve "getAsText" method
    • Websocket.Api: do not collect EdgeConfig if no websocket is connected
    • Create EdgeConfigFactory that takes care of building and caching EdgeConfig
    • Cache EdgeConfig and only incorporate ConfigurationEvents on Change; improves speed a lot

  • Fix handling of disappearing Components
  • Use EventAdmin to distribute updated EdgeConfig
  • Handle update of EdgeConfig by EdgeConfigWorker; this is required to get all available Channels

  • Fix behaviour of PID filter in low-priority Controllers 3ac5c31
    • This commit fixes a bug that would happen when a Controller that is using a PID filter has lower priority than another Controller; e.g. FixActivePower-Controller with higher priority than PeakShaving-Controller.
    • 1st: there was an issue that low+high limit would not be applied when they are equal - which happens e.g. after FixActivePower
    • 2nd: target value is now reduced to low+high limits before calculation starts; this avoids an always increasing error in above constellation
    • 3rd: when input already equals target; stop early as we are already there
    • also refactored "applyPidFilter" to use integers only; this is required for the "error = 0" clause to work properly
  • Improvements to FENECON DESS (#1067)
    • Set MaxApparentPower and Capacity Channels
  • Fix B-Control meter implementation (#1069)
  • Soltaro Battery Handling Controller (#1075)
  • GoodWe ET write implementation (#1077)

    • Configure pax logging only if it had not been configured before
    • Reduce logs on startup: introduce "isInitialized" state in Metadata service
    • Allow update of EdgeProductType
    • Clear debug system out printlns
  • improve performance to Postgres database: Use HikariCP: A solid, high-performance, JDBC connection pool https://github.com/brettwooldridge/HikariCP 141d605
