- UI: Label correction in SoC widget in history. - Fixed lables shown below. - Energy is represented as Power. - Entladung/Beladung is represented as Charge/Discharge power. replaced with Just Charge/Discharge. - Keba ReadWorker: fix possible Exception - Added Tests to identify when and how the exception can occur. - Tests for the "calculateCycleTime" work for multiple cases without throwing an exception - Tests could still be kept for code coverage - GoodWe: improve serial number filter - Change the serial number filter according to the goowe serial number rule. - Each GoodWe Type is now detected individually by its rated power in combination with its internal model series code. - GoodWeGridMeter: adjust CURRENT sign current if needed - Added Listener to ActivePowerLX Channels - Each Listeners checks if the nextValue for the power channel if the current and power have the same sign - If the sign is different the current channel is set with * -1 - JUnit Test Framework: add possibility to test raw modbus reads - `DummyModbusBridge` can now be used to test raw modbus reads - Apply new test for changes in GoodWe GridMeter and SunSpec - Also: Improve and apply `ReflectionUtils` - Replace exchangerate.host with Eurpean Central Bank API - `_host/OsVersion`: read os version as string - Added OS_VERSION Channel in Host Component - Write e. g. "11 (bullseye)" in channel for linux and for windows "Windows 11" - UI: replace currentUser observable with signal and solve login caching - Start recommended restructuring observables to signals - Fix `UserComponent` caching user information after logout - UI: Smaller Improvements - Auto capitalize ibn-installer key input field to show only upper case letters in mobile view (keyboard) - Fix wrong service number in offline manuals - adjust time of use chart in live with replacing the upper most left yAxis tick with the chart title - UI: remove app center app icon - Improving app center readability of icons - Time-of-use-Tariff Swisspower --------- Co-authored-by: Lukas Rieger <[email protected]> Co-authored-by: Sagar Venu <[email protected]> Co-authored-by: Sebastian Asen <[email protected]> Co-authored-by: Stefan Feilmeier <[email protected]> Co-authored-by: Johann Kaufmann <[email protected]> Co-authored-by: Michael Grill <[email protected]>
