  • Eastron SDM120 Meter by @fanass-dev in #2554
• UI: optional strict mode for improved code quality in #2623
• WebSocket: improved communication performance by @miettal in #2616

Details

Common/General

• Docs: update implementing a device by @Sn0w3y in #2601
• WebSocket: enable permessage-deflate to communication by @miettal in #2616

    • "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

    • 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

  • 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
