OpenEMS Edge

• ESS GoodWe: Improved implementation of getSurplusPower() by @tsicking in https://github.com/OpenEMS/openems/pull/3171
• Fix JSCalendar without recurrence rule by @tsicking in https://github.com/OpenEMS/openems/pull/3197
• FEMS Backports 2025-06-22 in https://github.com/OpenEMS/openems/pull/3206
  • EVSE KEBA UDP: fix stop charging session
  • GoodWe: use extended grid meter values
    • The meter values currently used, are limited to signed 16bit. This could cause an integer overflow - therefore goodwe added new S32 registers.
  • UpdateManager: Generic updates
    • added update manager which collects all Updateables
    • currently no implementation of an Updateable exists
    • Updateables are displayed in System view
  • E-Mobility: P40-App Fix
    • added check for HARDWARE_TYPE in KebaEvcs to make field readonly
    • added readonlyIf Method that dynamically makes field readonly based on BooleanExpression
  • KACO BatteryInverter: add "required" blocks
    • Fix sunspec initialization for kaco inverters
    • Kacos have a default modbus table with only common blocks when not configuration is not completed
    • initialization completes to fast without all required models/channels
    • Restart initialization until all required blocks are read
  • GoodWe: add new SolarGo states
    • Add SolarGo States when the corresponding register is not Undefined (0xffff)
  • KEBA App: fix Scheduler for readonly
    • Only add to Scheduler when not read only
  • Weather API: Open-Meteo implementation
    • Coordinates are stored in the Meta app and used as the basis for weather data retrieval
    • An OSGi component was added to integrate with the Open-meteo API
    • The component subscribes to the Open-meteo API for forecast data, polling every 6 hours
    • Forecasts cover the upcoming two days
    • The current weather is derived from the latest available forecast data
    • For historical weather data, a separate API call is made
    • This call supports a configurable start and end timestamp to define the time range
  • AppCenter: clever-pv public available
    • update roles to be installable by owner
    • added datasecurity hint
  • Power2Heat-Nature + MyPv AC-Thor9s and Askoma Read-Only implementation
    • Introducing new power2Heat Nature.
    • Read-Only implementations for MyPv AC-Thor9s and Askoma heating elements
    • New App including the UI.
  • FENECON Home Apps: add Dynamic and External limitation option for Feedintype
  • Power2Heat: fixes for energy calculation, etc.
    • Changed cycle to after process image
    • Updated translations
    • Added changes requested by previous review
  • AppCenter: set min access role from installer to owner for app delete
    • allow owner to deinstall apps
  • AppCenter: fix displaying "max feed in power" field based on Feed-In Type
• FEMS Backports 2025-07-01 in https://github.com/OpenEMS/openems/pull/3218
  • ToU: Addition of DSO providers and test cases
  • Power2Heat: declare heatingelement as consumption metered
  • Add dynamic to ips in getNetworkInfo
  • Add Channel Sum.UnmanagedProductionActivePower
    • Specs:
      • Interface: Sum (origin: ElectricityMeter and ESS DC Charger)
      • Type: Integer
      • Unit: W
      • Range: should be only positive; greater than or equal to PRODUCTION_ACTIVE_POWER
      • Note: this value represents the part of the active power production that is not actively managed or curtailed by OpenEMS or external regulations, i.e., it reflects the raw production before any control actions such as feed-in limitation due to grid constraints or new regulations on PV systems. This value can be used for forecasting or analysis of the unmanaged production.
    • Currently identical to ProductionActivePower (direct copy)
    • Future versions may decouple from controlled production values
  • Implement "Linear Model Production-Predictor" based on weather forecasts
    • A linear model was used, as a linear relationship between weather data and PV generation was identified
    • The model is retrained every two days using the most recent two weeks of data
    • Training features include solar irradiation data and time-of-day related features
    • Forecasts are generated using weather forecast data as input
    • The model is lightweight and computationally efficient
    • Numerous potential edge cases, such as insufficient training data, are already handled gracefully
  • Add optional Open-Meteo commercial API Key
    • An API key has been added for FENECON systems
    • Since it's only required for commercial use, the API remains functional without it
  • Code cleanups
    • Move Abstract SunSpec implementations for BatteryInverter, Meter and PV-Inverter to Modbus-Bridge bundle
    • Move Phase-related enums SingleOrAllPhase and SinglePhase to io.openems.edge.common/src/io/openems/edge/common/type/Phase.java
    • Add static imports
  • EVSE improvements
    • Refactor Profiles to Abilities and Actions for Charge-Point and Electric-Vehicle
    • Implement StateMachine in Evse.Controller.Single
    • Improve power distribution; considering "Steps" (Ampere vs MilliAmpere vs Watt)
  • Controller Ess Balancing: allow setting target grid Setpoint via Modbus
    • Before: external EMS could only send charge/discharge information to ESS.
    • This PR creates the option to also control the TargetGridSetPoint via Modbus ReadWrite
    • New WriteChannel "SET_GRID_ACTIVE_POWER" in ControllerEssBalancingImpl: Negative value = Feed-in; Positive value = Grid-Draw
    • Adapt ControllerEssBalancingImpl: Change priority so that SET_GRID_ACTIVE_POWER ist highest; 2nd (as up until now) config "targetGridSetPoint"
