So, if during the day the model realizes that the wrong profile was chosen, a better-fitting one is selected for the rest of the day. - The forecasted quarterly values are determined by the predicted profile. * EVSE New Architecture - Add State-Machine to EVSE Single Controller: - EV_NOT_CONNECTED: EV is not physically connected to the charge point. - EV_CONNECTED: EV is physically connected but not yet charging. - CHARGING: Regular charging is ongoing. EV is drawing current according to configured limits and conditions. - FINISHED_EV_STOP: Charging finished by EV. EV is not drawing power even if it would be allowed to. - FINISHED_ENERGY_SESSION_LIMIT: Charging is finished by OpenEMS because the configured `EnergySessionLimit` was reached. - prepared for more... - Add Change-Limit for rising set-points (3 % per second) - Improve surplus distribution: recursive call makes sure everything is distributed to max power - Drop `SESSION_LIMIT_REACHED` state; replaced with State-Machine - Improve JUnit tests and coverage - KEBA: use Enum for `setSetEnable()` (applies also to EVCS) - Phase-Switch is currently not working. Needs to be added to State-Machine - Successfully tested with 2 x KEBA P30 * Configurable minimum power for vehicle - Added min and max power in generic vehicle and generic vehicle app * KEBA UDP: disable flaky JUnit tests - UDP tests sometimes fail with `java.lang.Exception: On TestCase [#1]: expected ReadValue [CHARGING] got [UNDEFINED] for Channel [Status] in Nature [Evcs] on Inputs [[]]` * Tibber: switch to QUARTER_HOURLY prices - Change GraphQL to QUARTER_HOURLY resolution, update parsing of prices and JUnit tests - See https://developer.tibber.com/docs/changelog for details * GoodWe: * use new Registers for GridFeedInLimit and FixedPowerFactor: Registers for FENECON Commerical 50 changed * allow only possible EmsSetPower limits and correct AcImport/AcExport * Controller.Ess.RippleControlReceiver: Rundsteuerempfänger - Controller for Ripple Control Receiver - Digital Input 2 - Digital Input 4 are used as signal - DI2 reduces to 0%, DI3 to 30%, DI4 to 60% - If there are more than one relay active, the "strongest" limitation is used => e.g. 0% and 30% are activated => reducing to 0% power - Currently only for GoodWe Inverters => Feed-To-Grid Power Limit is set to the lowest of the two options: - MaxApparentPower * Limitation or the own set limit - removed MaxGridFeedInLimit of GridOptimizeCharge and BatteryInverter and added it in Meta app => uniform using of limit * Weather Forecast: keep data in channels - The current weather and the forecast for the next 24 hours are now being written in channels - This is more efficient in UI * Shelly: add `invert` config property to all ElectricityMeters * App.Heat.HeatingElement: ignoring heat and evcs components in the extern meter list * KACO Battery Inverter: introduce SunSpec EnumField16 - Sunspec channels are automatically created based on EnumField16 enums. - These channels are visible as StateChannels in the system. - Each channel’s status (OK, Warning, or Failure) is defined during setup—by default, channels are OK unless specifically configured as warnings. * Consistant Icons - changed icons and Buttons to be more consistently identified with functionality * Fix high and low price description for Octopus Heat TOU Tariff by @sthhs in https://github.com/OpenEMS/openems/pull/3344 * Update timeofusetariff octopus heat Config.java: typo by @sjjh in https://github.com/OpenEMS/openems/pull/3346 * FEMS Backports 2025-10-08 in https://github.com/OpenEMS/openems/pull/3353 * App.Meter.PqPlus available for OWNER * Weather.OpenMeteo: add random jitter to API calls to reduce simultaneous load * App.PvInverter.SolarEdge: make Modbus Unit ID configurable * Phase Rotation for Heating Element & Eastron meter - outsource enum "Phase Rotation" to make it independent - changing translations - implementing "Phase Rotation" in modbus protocoll of the Eastron meter - added property "Phase Rotation" in the Eastron meter app * implement KOSTAL PIKO PV inverter via HTTP/HTML parsing by @Sn0w3y in https://github.com/OpenEMS/openems/pull/3297 ## OpenEMS UI * FEMS Backports 2025-10-02 in https://github.com/OpenEMS/openems/pull/3339 * Migration to Angular 20 * Apply `ng generate @angular/core:control-flow` * VSCode: fix html formatting issues with new control flow syntax: [Reference](https://www.reddit.com/r/Angular2/comments/1j71x20/how_to_format_angulars_new_controlflow_syntax_in/) * Settings | Channels: add option to select multiple channels * EVSE New Architecture - Extend Evse with navigation to app center update page - Refactored app center update pages to be usable with new navigation - fix german/english translation of power * Fix Helpbutton-component not working due to wrong property name being checked * Time-of-Use-Tariff Ancillary Costs: Fix possible input errors * Style fixes * EVCS Cleanup - Added class EvcsComponent to clean up historic data generation in all views * fix Consumption flat widget * New Navigation: add check for isEnabled on component - prevent disabled components to be shown for new navigation * LiveDataService currentData: fix not refreshing bug * History Storage: add fallback channels for non hybrid ess - use active power for non hybridEss and subnavigation for phase details only for hybridEss * Unified icons for “Error” status * Settings: refactor to lazy loaded module - decrease size of init app bundle, this PR is focused on migrating Settings to standalone and lazy-loaded. - fixing changelog component not showing back-arrow when inistialising, improved back button behavior in header component by using Navigation services for dynamic visibility. - Ensured consistent back navigation across all routes, including when changelog.component is nested or reused. * Improve keyboard accessibility - Apply keyboard accessibility according to WCAG (Web Content Accessibility Guidelines) * GridOptimizedCharge: fix time format for live - displaying the endTimeDetailedDescription in Netzdienliche Beladung as 24h or 12h format depending on User's browser's language. * Warning Status: consistent usage of warning icon - changing display of warning status to have a warning sign / icon. where previously Fault & Warning statuses were displaying `alert-outline` sign / icon . * Add Weather Widget - Added new Weather Widget in Live View below the Energy Monitor - Displays current weather, 6-hour forecast, and daily forecast for the next 6 days - Shows temperature, general weather condition, and sun hours - Weather data is retrieved from the Edge using coordinates stored in Meta configuration - Forecasts are retrieved in quarter-hourly, hourly, and daily resolution for the next 7 days - Linear prediction model adapted to handle the new weather data format - Forecasts are cached on the Edge and the UI fetches only the data it currently needs * Settings: fix missing buttons -

Now, they are computed from the entire dataset, ensuring better coverage of all timestamps. - A new test case was introduced using an XML response that previously caused missing timestamp issues. * Time-of-Use-Tariffs: AppCenter: add max charge from grid setting * Added a property for every ToU app to set the maximale allowed charge from grid power * GoodWe: disable internal BatteryProtection - Disable internal goodwe battery protection called socProtect, that caused several problems. - After setting this register to 1, the maximum voltage values of the write-registers are used. * RabotCharge Time-of-Use-Tariff: fix price calculation * Home Battery: stop on critical min cell voltage * Battery values changed to null when there is no battery communication, because ModbusBridge invalidates all Modbus Channels then. * As a result the system restarted until it was in deep discharge. Use last defined value to check the minCellVoltage. * CleverPV: send EssDischargePower instead of EssActivePower * Clever-PV requires the actual battery charge/discharge power and not AC-side of hybrid inverter * Energy Scheduler v2: continuous improvements - Improve tests and logs - GridOptimizedCharge: fix possible NPE in EnergyScheduler - Improve InitialPopulation: this is crucial for v2. Because simulation is much slower, it is important to start with a good Initial Population. It is now possible for each EnergyScheduleHandler to suggest its own Initial Population (e.g. CHARGE_GRID in cheapest quarter) - Add index to GlobalOptimizationContext.Period, makes it easier to loop over them in a stream - Improve Jenetics Engine configuration: EliteSelector to make sure best Initial Populations survive; Alterers match better with the expected search task - Increase initial wait time to create GlobalOptimizationContext - e.g. for Home systems that require some time to read capacity * EVSE Edge Improvements - Add SURPLUS mode to EVSE Single Controller (works with only one EVSE simultaneously at the moment) - Add `manualEnergySessionLimit` and ENERGY_SESSION channels - only considered in EnergyScheduleHandler at the moment! - Add Energy Scheduler Simulation for manual modes (ZERO, MINIMUM, SURPLUS and FORCE) - EVSE KEBA via Modbus/TCP: - Add PhaseRotation - Calculate/distribute Power per phase * Home Battery: use new register for number of towers - New ATL versions cannot guarantee a value for TOWER_X_BMS_SOFTWARE_VERSION. This makes it impossible to calculate the number of towers based on this values. - The new Register was not present in the initial test version but should have been available since the first container shipment. * **Time-of-Use App Octopus Go** * Energy Scheduler v2 + EVSE: general improvements - Sinexcel: use static imports; drop unused EventTopics - Energy Scheduler v2 - Fix unique ID per EnergyScheduleHandler - EVSE - ClusterCtrl: move logic to testable static method - SingleCtrl: implement SESSION_ENERGY, manualEnergySessionLimit config property and SESSION_LIMIT_REACHED - KEBA: separte hardware wiring from S10 configuration * FEMS Backports 2025-03-28 in https://github.com/OpenEMS/openems/pull/3075 * Meta: add Grid Connection Point Fuse Limit + fix EVCS cluster power restrictions - Defines the maximum current allowed at the Grid Connection Point (GCP), i.e. the rating of the fuses. - changed mlpm prompt in Evcs Apps - made mlpm prompt required - added default value to mlpm promt base on fuse limit * NetworkConfig: added settings for network forwarding * Added settings in network component to set "IPv4Forwarding" & "IPMasquerade" only with manual rpc request or AppCenter configuration * ESS Generic Managed: Allow manual clearing of timeout failures * Updating the ESS component sets the status of the state machine back to undefined. * In the Undefined state, the ESS component decides whether to stop or start depending on the start/stop target if there is no error. * However, when the component is updated, the start/stop configuration that has already been set is also reset and does not receive a target update from the system component, as the system component is already in Running. * The moment in which ess target is updated only takes place in the system component go_running. * The restart can therefore only take place if the ess component failure is deleted without the ess component being updated. * This requires an implementation in the system component that removes the ess “max start/stop attempt failure ”s. * Octopus Go: fix price calculation, change config to Cent/kWh, add JUnit tests * ToU Controller: apply PID filter for systems with disabled PID * AppCenter: App for clever-PV * LSTM: fixed spelling mistake * ModbusTcp/Rtu: reset Invalid Modbus Call error after 60 seconds * Often Modbus-Api shows a "Invalid Modbus Function Call" error because e.g. IP of a relay board was incorrectly configured. Even after we have fixed the root cause, Modbus-Api remains in a fault state. Previously, this could easily be cleared by restarting the component. Since the modified method was introduced, this is no longer the case. * Removed debounce PROCESS_IMAGE_FAULT * Channel PROCESS_IMAGE_FAULT is set to false if there is no error within 60 seconds * JSCalendar, Energy Scheduler, EVSE Backports - JSCalendar - add helpers to handle Lists of Tasks - fix getNextOccurrence - JsonUtils: use objects and not primitives - Add RegexUtils - Energy Scheduler - Add Serializer and Deserializer with Factory-PID and Component-ID - Replace Double for cost with "Fitness" object; allows considering multi-level constraints (hard+soft) - Improve RunOptimizerFromLogApp to re-simulate real data - Avoid usage of Exceptions in normal execution flow - Identify managedConsumption per Controller-ID in EnergyFlow - Add `RunOptimizerApp` for easier simulation & testing - EVSE - Improve calculation of surplus power - Add ACTUAL_MODE channel for Single-Controller - Implement SMART mode (incl. field- and JUnit-test) * Meters: add "invert" in all meters and apps - Can now invert meters in the app config - implemented INVERT ElementToChannelConverter in all meters that had not yet implemented it * AppCenter: clever-PV data privacy notification - Added logic in OpenemsAppPermissions to only allow certain roles to install - Used logic to make enerix not installabe by Installers * Energy Scheduler: improve logging, handling and prevention of Exceptions * FEMS Backports 2025-04-01 in https://github.com/OpenEMS/openems/pull/3080 * Excel Export: improvements - Added io.openems.edge.ess.dccharger.api.EssDcCharger to XlsxExportUtil - Added charge0 to XlsxExportUtilTest - Added Method for Xlsx float value with 2 decimals * EVSE Improvements - Add Chart to UI Modal - Better handling of unplugged state - Add Schedule also to EnergyScheduleHandlers WithOnlyOneMode - Add JSONRPC-Response for SMART/MANUAL Schedule * AppCenter: changed default modbus for meter apps * EVCS Heidelberg Wallbox Energy Control readOnly - This is an implementation of pure modbus readonly EVCS based on ElectricityMeter ## OpenEMS UI * FEMS Backports 2025-03-11 in https://github.com/OpenEMS/openems/pull/3046 * Refactor Fixdigitaloutput modal with formGroup * Creating unit testable form with formGroup for modals * EVSE UI Improvements: add mode SURPLUS * fix display of dimming in grid * Hiding and showing of dimming in grid history was not applied right * Replace manual component configurator with Estimated Configuration response * Use fallback LIGHT_MODE for them popover selection * Using fallback theme `LIGHT` if popover has been closed without choosing a theme * Change tooltip display state for heatpump * Fixing tooltip displayed heatpump state * Change chartjs hover over pointer style - Improving chartjs hover mode, point out currently selected timestamps respective datasets value - Refactoring currentEdge observable to signal -> resolving lifecycle issue * fix chartjs legend display error Legend Labels not generated * FEMS Backports 2025-03-28 in https://github.com/OpenEMS/openems/pull/3075 * Fix read only twice in history * New Evcs without DeprecatedEvcs showed twice instead of once in cosumption history * Added filter to evcsComponents * Translations for UserComponent - Adding translations for `/user` - the UserComponent * Fix modal templates - Fixing modals using the `currentEdge` signal in template and still used async pipe - Could have been avoided with strict templates ts config... * Change consumption total color * Redesign ion-toggle - Redesigning ion-toggle and adjusting the look to match the Darkmode feature. * Add battery extension capacity info - Add warning to battery extension for battery referencing * Prevent y scale min to equal max - Prevent chart y scale for power and energy values to be showing no line due to max and min of y scale being the same * Fix heatpump chart - `State` - Channel values from 0 to 3 need to be scaled to 1 to 4 due to differences with [docs](https://docs.fenecon.de/de/fems/fems-app/App_Power-to-Heat_Benutzerhandbuch.html#_einbindung) * Change docs links * Change y scale title placement * Unify translations (en) * FEMS Backports 2025-04-01 in https://github.com/OpenEMS/openems/pull/3080 * Fix History show/hide month & year view -

# Release Highlights * **Clever-PV Controller** * New Controller `Controller.Clever-PV` sends core data to Clever-PV (https://clever-pv.com) * **Electrical Vehicle Supply Equipment (EVSE)** * WIP for a future replacement of the current EVCS APIs. The new namespace is "Electrical Vehicle Supply Equipment (EVSE)". # Details ## Common/General * Update Gradle to v8.13 by @sfeilmeier in https://github.com/OpenEMS/openems/pull/3027 * Increased karma Timeout ## OpenEMS Edge * FEMS Backports 2025-02-07 in https://github.com/OpenEMS/openems/pull/3005 * *This fixes a critical bug in Time-of-Use-Tariff Optimizer in https://github.com/OpenEMS/openems/releases/tag/2025.2.0* * AppCenter: Fix selecting relays - added filter for initial check if an app can be installed based on available relays (CheckRelayCountFilters.deviceHardware) - properly handle selecting multiple relays (array value) - moved required setting to right places - added missing options hint in SelectGroupBuilder if none are available - only apply modal of safe input when confirmed * ToU Optimizer: fix BALANCING fallback schedule - A endless loop causes fallback schedule. Bug became visible after recently added null-check - Copied logic from new Optimizer.java: src/branch/develop/io.openems.edge.energy/src/io/openems/edge/energy/optimizer/Optimizer.java#L198-L202 * EVCS: new PhaseRotation which supports better Modbus handling - Native EVCS support for PhaseRotation - switched nature enum `PhaseRotation` to a new format - added method `Evcs.getPhaseRotation()` (BREAKING CHANGE) - applied code cleanup * JsonSerializer: improved serialization - added tests - added StringParser of e. g. UUID, SemanticVersion, ChannelAddress, .... - added number parsing - added polymorphic parsing for subclasses of one type - added boolean parsing - EmptyObject to reduce duplicated empty request/response - added nullable paths for every type - added primitive path with strict parsing - updated a lot of json rpc methods * FEMS Backports 2025-02-25 in https://github.com/OpenEMS/openems/pull/3024 * GoodWe: increase minimum power that will be ignored. * Bigger systems still have 79W permanent charge power, while the dynamic tariff would charge/discharge with zero. * After a longer discussion the values below 100W will be now ignored to avoid a lot of service cases that can not be explained. * **Clever-PV Controller** * New Controller `Controller.Clever-PV` sends core data to Clever-PV Push API every 15 seconds * See docs: https://www.clever-pv.com/anleitungen/push-api * Evcs: add helpers for phases * add `Evcs:addCalculatePhasesListeners()` * add `Evcs:addCalculatePhasesFromActivePowerAndPhaseCurrents()` * Note: typical EVCS hardware models provide `CURRENT_L1-3`, and `ActivePower`, but some models provide only `CURRENT_L1-3` and some other models provide only `ACTIVE_POWER_L1-3`. Therefore these methods are added to easily compute the missing channel values. * **Electrical Vehicle Supply Equipment (EVSE)** * This is WIP for a future replacement of the current EVCS APIs. The new namespace is "Electrical Vehicle Supply Equipment (EVSE)". * This PR provides: * APIs for * Electric Vehicle * Charge Point * Implementations: * KEBA P30/P40 via Modbus/TCP (`Evse.ChargePoint.Keba`) * Generic Electric Vehicle (`Evse.ElectricVehicle.Generic`) * Controllers: * Single Charge-Point (`Evse.Controller.Single`) * Cluster of Charge-Point-Controllers (`Evse.Controller.Cluster`) * Simple UI to control the Charge-Mode of Charge-Points * NOTE: All of this might be heavily refactored in future. Having it on develop helps us to test it easier in production. It does not affect any existing EVCS implementations. * BitsWordElement: Extend it via setToNullIfBit to indicate the invalid bit value input * Integrate the convert option for BitsWordELement * According to the given function/condition each bit channel values can be manipulated * The main reason of this implementation is to in order to indicate if value present or default value delivered * As an example; with this approach in case of default value detection, the values can be set to null * Similar approach was implemented in ElementToChannelConverter as "Set_to_null_for_default()" method * Implement UpdateUserSettingsRequest for edge-uiwebsocket * Adding updateUserSettingsRequest support for edge-ui-websocket request handler * Follow up to darkmode settings not being able to set locally * AppCenter: Only try to get Component if needed * If a component is not satisfied and therfor not startet an exception gets throw because the component can not be obtained * Solution: only get component if first method fails or can not provide the properties * KEBA: fix EnergyLimitReached when no Limit configured * Currently a bug starts to popup more and more in ticket. * -> Keba Charging Station has the Status ENERGY_LIMIT_REACHED eventhough energyLimit is not activated * Added removed check for limit != 0 (limit 0 should mean that no limit is set) in status mapping in ReadHandler of Keba * Energy Scheduler v2 / Time-of-Use-Tariff optimization (ALPHA) by @sfeilmeier in https://github.com/OpenEMS/openems/pull/3029 ## OpenEMS UI * FEMS Backports 2025-02-07 in https://github.com/OpenEMS/openems/pull/3005 * History consumption chart non deprecated evcs not taken into account for total consumption - in history chart "consumption". Ensure that non deprecatedEvcs (new implementations) are not added to "sonstiger Verbrauch" - if deprecatedEvcs is not implemented (chargepower channel nature) then it is added to consumption metered * FEMS Backports 2025-02-25 in https://github.com/OpenEMS/openems/pull/3024 * time-of-use rename state to status * Dark-mode Popup * Displaying Popup after successful log in, to announce the Dark-mode new feature for users, showing it only once after users get the new software release. * Angular 19 migration fixes * setting chart afterTitle directly * Formly Radio Button * Add last setup protocol download to profile * Downloading latest setup protocol in `profile` * IOS Fixes * file download for excel export and last setup protocol did also not work on mobile with browser, now only *in app* downloads are not working * theme selection popover radio buttons not shown, due to default ios design, changing to material design * -> before checkmark as radio icon with no circle, now with circle * Enforce datetime format for ion-datetime * fix datetime format of `ion-datetime`, ionic changed returned format of the date string * unit test to avoid this in future migrations * Change visibility of producttype and sumState filter * changing visibility of producttype and sumState filters in ems-overview from `admin` to `installer` * Enable darkmode locally & restrict float number decimals * Enabling setting darkmode for local monitoring * restrict float number decimals in y Axis ticks * Phase-accurate button change * Correcting buttons names on the footer navigation in history Consumption chart view. * Fix evcs modal range slider bug * Fixing ion-range bug ## Version Upgrades * Bump info.faljse:SDNotify from 1.5 to 1.6 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/3011 * Bump org.apache.felix:org.apache.felix.webconsole from 5.0.8 to 5.0.10 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/3010 * Bump com.google.code.gson:gson from 2.11.0 to 2.12.1 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/3002 * Bump ngx-spinner from 17.0.0 to 19.0.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3016 * Bump swiper from 11.2.1 to 11.2.4 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3019 * Bump rxjs from 7.8.1 to 7.8.2 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3022 * Bump the angular group across 1 directory with 4 updates by @dependabot in https://github.com/OpenEMS/openems/pull/3023 * Bump fr.turri:aXMLRPC from 1.16.0 to 1.17.0 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/3001 * Bump @capacitor-community/file-opener from 6.0.1 to 7.0.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2990 * Bump the eslint group across 1 directory with 4 updates by @dependabot in https://github.com/OpenEMS/openems/pull/3028 * Bump chart.js from 4.4.7 to 4.4.8 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3030 * Bump globals from 15.14.0 to 16.0.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3031 * Bump ngx-cookie-service from 19.0.0 to 19.1.2 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/3032 * Bump ng2-charts from 7.0.0 to 8.0.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2954 ## New Contributors * @HaSp97 made her first contribution **Full Changelog**: https://github.com/OpenEMS/openems/compare/2025.2.0...2025.3.0

# Details ## Common/General * General Cleanup by @sfeilmeier in https://github.com/OpenEMS/openems/pull/2949 ## OpenEMS Edge * Siemens Logo as network relay board by @DerWahreKlinki in https://github.com/OpenEMS/openems/pull/2350 * Shelly: common executeWrite() method & many JUnit tests by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2658 * Controller IO Heating Room by @sfeilmeier in https://github.com/OpenEMS/openems/pull/2950 * FEMS Backports 2025-01-16 in https://github.com/OpenEMS/openems/pull/2969 - JsonUtils: Update switch cases with pattern matching - HttpBridge: add detailed Logger - Moved DebugMode to Common - Added DebugMode to BridgeHttp - Added parameter of type DebugMode to NetworkEndpointFetcher - Added Detailed log of result in fetchEndpoint if DebugMode is DETAILED - Set DebugMode to DETAILED in HardyBarthEvcsImpl if debug is true in config - Sum + ESS: update Modbus table descriptions - Adds and changes descriptions of the modbus tables - KEBA: fix issue with SessionEnergy - Add KEBA specific R2State-enum (for "Report 2") - KEBA: drop CHARGING_REJECTED - SessionEnergy is set to 0 on UNPLUGGED event - Modbus-Api-Controller: add RTU and unify controllers to abstract superclass - Implementation of ModbusRTU - Refactoring of ModbusTCP to avoid redundant classes - Implementation of ModbusRTU App - Added "Download Protocol" button for ModbusRtu - AppCenter Home: NA-Protection changed text - changed na-protection text - IO Weidmüller: Added UR20_16DI_P module - Symmetric Battery Inverter: add cabinet temperature channel - Added a "TEMPERATURE_CABINET" channel in the Battery inverter interface. - HardyBarth: temporary fix for `null` responses - This fixes an issue with interrupted charging sessions due to `null` values. - added check for null values in HardyBarthReadUtils - The first 3 null values are ignored and no values are written in these cycles - Afterwards null values are written in channels as usual - AppCenter: add estimated configuration endpoint for IBN - Added endpoint to retrieve estimated installation configuration - AppCenter: Meta App + Update Component via apps - Added core app for meta component - Added Logic for updating component config via their apps - EmergencyReserveFromGrid: start charging without delay from ramp - Added check with previous state that ignores ramp for 1 cycle * FEMS Backports 2025-01-20 in https://github.com/OpenEMS/openems/pull/2976 - Code Cleanup for Java 21 - Migrate Switch-Case-Expressions to Switch-Case-Statements - General code cleanup (using Eclipse "Clean up" tool) - EVCS Mennekes: cleanup - Cleanup Eclipse warning (#2971) * Correct FENECON Home Battery Unit for Cell Voltages by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2974 * Fix VerifyError in EdgeConfigWorker by @sfeilmeier in https://github.com/OpenEMS/openems/pull/2987 * FEMS Backports 2025-02-02 in https://github.com/OpenEMS/openems/pull/2997 * Host: extend getIpAddresses Request * Extended jsonRpc request for getIpAddresses with more data for networkInterfaces and IP routing table * Mennekes Relase: Remove AppPermissions * Remove App Permissions from Mennekes for upcoming release * SunSpec: set correct OpenemsType for floating point values * See commit details for an example of the changes for a Fronius PV Inverter with SunSpec Block 113 * Originally we tried to avoid floating point in favour of integer numbers to avoid very frequent sending of changed values. This has been solved in the meantime with a DEFAULT_PERSISTENCE_PRIORITY of VERY_LOW for SunSpec channels. * ModbusTcp Read-Only: add modified handling * Adds modified method to ModbusTcp Read-Only * AppCenter: fix bug where all array properties cant be modified - Modifying array properties results in an error "expected array length 1 not 3" - "fixed" by changing order of checks to first check if property can be modified and then check if they are the same value - TODO future if access check on a array based property happens it needs to be modified to handle array values - remove excessive log if component does not exist in `ComponentManager#getComponentProperties` * Energy Optimizer: fix possible NPE - This fixes ``` [_energy ] ERROR [s.common.worker.AbstractWorker] Worker error. NullPointerException: Cannot invoke "io.jenetics.Genotype.get(int)" because "bestGt" is null java.lang.NullPointerException: Cannot invoke "io.jenetics.Genotype.get(int)" because "bestGt" is null ``` - According to docs the Collector can indeed return `null`: https://github.com/jenetics/jenetics/blob/master/jenetics/src/main/java/io/jenetics/engine/EvolutionResult.java#L475-L476 * ElectricityMeter: added calculateCurrentsFromActivePowerAndVoltage and calculatePhasesFromVoltage - ElectricityMeter enhancement for more easier integration of future EVCSs. Method may be useful for general ElectricityMeter implementations as well. That's why it was placed in ElectricityMeter and not in Evcs. * Windows Fix for IP Validation in Apps - IP Validation Regex is now Compatible with Windows again. (Currently when OpenEMS is run locally apps with IP Validation can't be installed) * GoodWeGridMeter: ElementToChannelConverter NP-Fix - Null check in element to channel converter * GoodWe: improve Battery Power Settings - Some of the Power settings for the goodwe were not applied correctly (Per default disabled, wrong scale factors, wrong register mapping cosPhiF != PU) * GoodWe: ignore impossible power values - The DcActivePower resgister of GoodWe is giving 20-40 watt values when the SoC is 0 or 100 and there is no real charge/discharge of the battery happening. This values will be ignored to avoid wrong energy values, as the energy is calculated based on the active power. - The same occurs when the battery is getting a 0 charge/discharge set point. If the SoC is between 0 and 100 it is also ignoring this low power values when the current EmsPowerMode is Charge/Discharge Bat & the EmsPowerSet is 0 W ## OpenEMS UI * Dynamic numberformat conversion by using current locale by @miettal in https://github.com/OpenEMS/openems/pull/2757 * Overview search: trigger on every input change by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2935 * Add defaultLanguage setting to src/environments by @miettal in https://github.com/OpenEMS/openems/pull/2756 * Fix component.update View by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2958 * Fix formly form styles by @lukasrgr in https://github.com/OpenEMS/openems/pull/2962 * Switch from `ionChange` to `ionInput` for Real-Time Filtering in Search Bar by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2963 * FEMS Backports 2025-01-16 in https://github.com/OpenEMS/openems/pull/2969 - Prepare Login Improvements - Added template to override the default formly behaviour bugs - fix styling of `negative-values` and `positive-values` info * FEMS Backports 2025-01-20 in https://github.com/OpenEMS/openems/pull/2976 - use user language instead of browser lang for locale - replace locale being overwritten with browserlang to be using the user lang - fix czech locale, `cz` throwing errors for - piping (using angular pipes) - formatting of numbers - replacing it with `cs` -> [Ref](https://github.com/angular/common-builds/blob/main/locales/global/cs.js) - Improve Modbus Widget - fixes name of channel in ModbusTCP widget (e.g. Ess1SetActivePowerEquals was shown as SetActivePowerEquals/706 in OM) - Several ess lead to repeating register names in ModbusTcp widget. - Dark mode pick-date improvements - Enhancing styles of popover in accordance with dark-mode feature. - Add handling for `Controller.IO.Heating.Room` * migrate .eslintrc to eslint.config.mjs by @miettal in https://github.com/OpenEMS/openems/pull/2675 * FEMS Backports 2025-02-02 in https://github.com/OpenEMS/openems/pull/2997 * Change display color of currency axes - fix coloring of yAxes for currency - extending eslint rule [`no-unused-vars`](https://eslint.org/docs/latest/rules/no-unused-vars#ignorerestsiblings) with `ignoreRestSiblings`: destructuring throws otherwise an error for unused sibling * Adjust custom time range chart display - Adjust time-range picker in mode `Custom` to display only the months queried for monthly resolution, before if start and endpoint are in a different year, it would fill up both years to show 12 months per year * Fix searchbar request overload - reducing calls of `GetEdgesRequest` and waiting for last requests response - avoids showing every response - introduce 1 second `debounce` * Refactor heat pump history - Using `Time`-channels for bar charts - creating refactored standalone unit tested lazy loaded history for heatpump - sanitizing data for io time channels if they are not adding up to - 24h (1 day - month view) -> rounding if only one minute missing - 744h (31 day month - year view) ... -> rounding if only one hour missing - -> increasing `RegularStateTime` by the missing diff - Attention: There still could be some deviation due to OpenEMS Edge being offline during systemupdate * Improve styling * Remove unused imports in GetNetworkInfo and MennekesEvcs * Controller.IO.Heating.Room: add UI Live widget - Add UI Live Flat and Modal for `Controller.IO.Heating.Room` - This implementation could in future serve as a proof of concept for new JSCalendar configurations * EVCS Cluster: remove slides from modal - Because of display errors after recent Angular & Ionic update. * UI: Refactor Info Text Blocks into a Reusable Template by @Sn0w3y in https://github.com/OpenEMS/openems/pull/2961 ## Version Upgrades * Bump com.squareup.okio:okio-jvm from 3.9.1 to 3.10.0 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/2951 * Bump @typescript-eslint/types from 8.19.0 to 8.19.1 in /ui in the eslint group by @dependabot in https://github.com/OpenEMS/openems/pull/2952 * Bump @awesome-cordova-plugins/file-opener from 6.13.0 to 6.14.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2953 * Bump @awesome-cordova-plugins/core from 6.13.0 to 6.14.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2955 * Bump swiper from 11.1.15 to 11.2.0 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2956 * Bump uuid from 11.0.3 to 11.0.4 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2957 * Bump the eslint group in /ui with 2 updates by @dependabot in https://github.com/OpenEMS/openems/pull/2967 * Bump swiper from 11.2.0 to 11.2.1 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2968 * Bump com.squareup.okio:okio-jvm from 3.10.0 to 3.10.2 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/2965 * Bump org.postgresql:postgresql from 42.7.4 to 42.7.5 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/2983 * Bump the pax-logging group in /cnf with 2 updates by @dependabot in https://github.com/OpenEMS/openems/pull/2982 * Bump the bouncycastle group in /cnf with 2 updates by @dependabot in https://github.com/OpenEMS/openems/pull/2981 * Bump @types/qs from 6.9.17 to 6.9.18 in /ui by @dependabot in https://github.com/OpenEMS/openems/pull/2980 * Bump org.apache.felix:org.apache.felix.http.jetty from 5.1.26 to 5.1.28 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/2994 * Bump org.jetbrains.kotlin:kotlin-osgi-bundle from 2.1.0 to 2.1.10 in /cnf by @dependabot in https://github.com/OpenEMS/openems/pull/2993 **Full Changelog**: https://github.com/OpenEMS/openems/compare/2025.1.0...2025.2.0 --------- Co-authored-by: Stefan Feilmeier <3515268+sfeilmeier@users.noreply.github.com> Co-authored-by: Lukas Rieger <73471197+lukasrgr@users.noreply.github.com> Co-authored-by: Johann Kaufmann <165755282+johannk24@users.noreply.github.com> Co-authored-by: Michael Grill <59126309+michaelgrill@users.noreply.github.com> Co-authored-by: Fabian Brandtner <10850256+fabian94533@users.noreply.github.com> Co-authored-by: Sebastian Asen <47855186+sebastianasen@users.noreply.github.com> Co-authored-by: Christian Lehne <51822163+clehne@users.noreply.github.com>
