Details

Common/General

• Docs: update implementing a device by @Sn0w3y in #2601
• WebSocket: enable permessage-deflate to communication by @miettal in #2616
• Apply Eclipse Format & Organize Imports; fix resource leak by @Sn0w3y in #2617
• Refactor RPC handling by @michaelgrill in #2610
• FEMS Backports 2023-04 in #2623
  • Change Unit EUROS_PER_MEGAWATT_HOUR to MONEY_PER_MEGAWATT_HOUR
  • Prepare-commit: add UI build+test to script
    • "Coding Guidelines" should also cover UI development (https://openems.github.io/openems.io/openems/latest/contribute/coding-guidelines.html#_openems_edge_backend)
  • CI: Update node to v20 LTS

OpenEMS Backend

• FEMS Backports 2023-04 in #2623
  • Add API for Simulation-Engine Component
    • In future this should be used for scenario simulations, like what would have been the benefit of using an additional battery module

OpenEMS Edge

• MQTT API Controller: add optional config parameter to specify a topic prefix by @samuelBloch in #2553
• SunSpec: Channel values synchronized by @tsicking in #2609
• Implement new Shelly Plus Plug S by @Sn0w3y in #2529
• Updates Microcare / Eastron and Implements Meter SDM120 by @Sn0w3y in #2554
• FEMS Backports 2023-04 in #2623

  • Modbus-Bridge:

    • Improve SunSpec handling for SMA PV-Inverter: certain versions do not provide END_OF_MAP but throw ILLEGAL_ADDRESS_EXCEPTION instead, causing the previous SunSpec implementation to get stuck while parsing
    • Remove unnecessary throws OpenemsException and try...catch in certain places (defineModbusProtocol(), new ModbusProtocol(), addTask(),...)
    • Optionally provide ExecuteState of an entire ModbusTask; this allows for more fine-grained evaluation of read errors

  • Switch to updated readElementOnce and/or improve brevity of CompletableFuture by using thenCompose instead of thenAccept in...

  • RRD4j: correctly postprocess queried data

    • fix querying data with different resolution than 5 Minutes

  • Time-of-Use: split Optimizer and Controller

    • Introduce new Bundles for Energy and Energy API
    • Time-of-Use-Controller and EnergyScheduler are still tightly coupled for now, as this is an ongoing refactoring. Eventually they should only communicate via EnergySchedulable
    • Move Optimizer (i.e. all Jenetics related code) to Energy
    • New Channel _sum/GridBuyPrice
    • UI: show data in [kW] and cleanup code
    • Tibber: Homes-Filter could not be unset

  • KACO Blueplanet Gridsave BatteryInverter: state-machine improvement

    • Update Kaco Blueplanet Gridsave state-machine
    • Add grid disconnection failure state channel
    • Replace MAX_START_ATTEMPTS with MAX_START_TIMEOUT

  • GoodWe

    • Optionally show values per MPPT; not per String
      • GoodWeChargerTwoStringImpl was used to represent one string from a GoodWe MPPT tracker that is responsible for two strings (GoodWe ET-Systems).
      • Possible values given by GoodWe are: MPPT Current, MPPT Power, String Current, String Voltage
      • As the current values of one string are incorrect (so far DSP-Version 12, ARM-Version 27) the power cannot be calculated as expected.
      • A new Component GoodWeChargerMpptTwoStringImpl is mirroring the GoodWe values to get the important values from: MPPT Current, MPPT Power, String Voltage (One of the two strings)
    • Update BMS Registers ChargeMaxVoltage & DischargeMinVoltage
      • Set ChargeMaxVoltage & DischargeMinVoltage
      • Handle inverter specific behaviour on empty/full battery

OpenEMS UI

• Center Text in Footer by @Sn0w3y in #2594
• FEMS Backports 2023-04 in #2623
  • Add optional strict mode
    • Another step towards strict mode in UI
    • Add typescript-strict-plugin -> https://github.com/allegro/typescript-strict-plugin
    • Add tsc and tsc-strict to CI build
    • Add // @ts-strict-ignore comment in non-compliant code files
  • Update to Angular Version 16.
    • Replacing kekeh/angular-mydatepicker with its fork nodro7/angular-mydatepicker
  • Revert calculating stepSize for charts
    • Removing stepSize calculation due to chartjs breaking style in some circumstances
    • keeping max ticks limit at 6
  • Change resolution from 20 to 15 minutes
  • Remove dead link from ChpSoc (BHKW) Widget in history
  • Settings|Channels: fix Persistence Priority warning
    • Warning for persistencePriority lower than backends global priority, was also shown for equals
  • Hide FooterComponent for history Children due to overlapping on different heights
    • Footercomponent overlapping content.
    • Chartjs -> responsive charts approach of setting fixed height is causing the problem, onZoom event doesnt resize the charts canvas and chart canvas gets moved down into the footer
  • Footer: fix esLint autofix mistake; hide for history detail views
  • Revert adding detail navigation to production history (this is a planned feature that was accidentially merged)
  • Fix Page count of edges pagination on initial search
