0.20.4 (2026-10-24)

🔧 Maintenance & Compatibility

• Repository Checker Fixes: Addressed multiple warnings from the ioBroker repository checker.
• Node.js Requirement: Updated minimum Node.js requirement to >= 22 in package.json and io-package.json to meet current adapter standards.
• UI Layout: Added missing responsive size attributes (xs, sm, md, lg, xl) to elements in the new updates configuration tab.
• Translations: Added missing i18n translations for all supported languages in the configuration dropdown menus (COP sources and ZIP control mode).
• Metadata: Removed non-existent version entries from the news section in io-package.json.

✨ Features & Enhancements

• Notification Center: Introduced a dedicated notification category (lwpSystem) for firmware updates and system info to cleanly separate them from critical heat pump errors in the ioBroker UI.

0.21.0 (2026-10-24)

🚀 New Features

• PV Surplus Management (PV-Ready): Introduced a fully integrated, automated PV surplus control system.
• PV Hysteresis Control: Added a dedicated stop threshold (pv_threshold_stop) to the PV surplus manager. This prevents the heat pump from cancelling its own boost cycle by consuming the solar surplus (feedback loop). The system now supports independent start and stop boundaries (Schmitt trigger logic).
• Dynamic Setpoint Boost: Automatically raises hot water and heating setpoints (wear-free via Modbus RAM) based on your current grid feed-in.
• Smart Timers: Includes customizable start and stop delay timers to prevent compressor short-cycling during variable cloud cover.
• Cycle Protection: Added a "finish cycle" safety feature. If the solar surplus drops, the adapter intelligently waits for an active heating or hot water cycle to finish before reverting the setpoints, protecting the compressor hardware.
• PV Telemetry: Added three new virtual datapoints under Information.17_PV_Surplus (pv_boost_active, pv_boost_active_since, and pv_boost_last_activation) to make the current surplus control status transparently available for external ioBroker visualizations.
• Battery Prioritization (PV): Added an optional feature to include your home battery's charging power into the PV surplus calculation. This allows you to treat the heat pump as the primary thermal battery, intercepting the solar power to heat up the house or hot water before it flows into your chemical battery.

🐛 Bugfixes & Tweaks

• Cycle Optimization vs. PV Logic: Fixed an edge-case bug where a temporary high target temperature from the cycle optimization module leaked into the PV surplus manager if the heat pump skipped the standby/idle state. The adapter now explicitly resets cross-cycle targets and forces the PV manager to reference the secure baseline configuration limits.
• Modbus Stability: Fixed a critical race condition in the Modbus manager. Concurrent read and write operations no longer share a single global client, preventing connection collisions and adapter crashes during hybrid mode operations.
• API Modernization: Replaced deprecated setStateAsync calls in the PV manager with the modern Promise-based setState API to comply with the latest ioBroker adapter guidelines and resolve TypeScript warnings.
• Unit Conversion: The PV feed-in datapoint now natively supports kilowatts (kW) via a new toggle in the configuration UI, automatically converting it to Watts internally.
• Admin UI Polish: Replaced HTML-based information blocks in the configuration UI with native ioBroker JSON components to bypass React XSS-filtering issues and ensure clean rendering.

0.21.1 (2026-10-24)

🐛 Bugfixes & Tweaks

• PV Manager Target & Offset Fixes: Fixed remaining references to the read-only Wamwassertemperatur_Soll datapoint in activateBoost and deactivateBoost (now consistently targeting temperature_hot_water_target). Resolved a baseline mix-up where fusspunkt was mistakenly applied to the parallel offset (heating_temperature), and fixed the heating saturation check (isHzFull) to compare actual return temperature against target return + hysteresis without prematurely revoking active boosts.
• Cycle Optimization & Heating Limit: Replaced the language-dependent 'Heating limit' string check during idle with a reliable numerical evaluation of the heating limit parameters. Added a !pvIsBoostActive guard to prevent forced hot water triggers from overwriting active solar boosts, and included a baseline reset (0 K) for heating_temperature in setIdleDefaults.
• ZIP Controller Timer Fix: Fixed a bug in zipManager (internal controller mode) where hot water timer slots (WW_MoSo_...) were backed up and overwritten instead of the circulation pump timer slots (Zirkulation_MoSo_...), and improved time string restoration.
• COP Calculation Accuracy: Fixed a UTC timezone offset in the daily rollover check so COP snapshots occur accurately at local midnight (00:00). Included defrosting cycles (WP_BZ_akt = 4) in the heating COP bucket and added clamping against negative deltas if external energy meters are reset.
• Object Management & Virtual States: Removed a redundant loop in onReady that recreated disabled virtual datapoints on startup, and fixed PREFIX_MAPPING for weekend timer tables (SaSo) to properly reference the 52SatSun configuration flags.

[TbsJah]

0.22.0 (2026-10-24)

🐛 Performance & Tweaks

• Modbus Queue & Socket Protection: Added a sequential operation queue (mutex) with a 50ms socket release delay in ModbusManager to prevent TCP port 502 connection collisions when polling and event-driven writes occur simultaneously.
• COP Database Optimization: Added an in-memory object cache (ensuredObjects) to copManager, eliminating redundant setObjectNotExistsAsync database calls during every polling cycle.
• DTA Backup & Firmware Check Improvements: Added a 30-second request timeout (AbortSignal.timeout) and proper dta_history file naming on fallback to backupManager, and expanded the version regex in updateManager to support F1., WWB, and smo firmware strings.

Hallo zusammen,

nach den umfangreichen Updates der letzten Zeit (PV-Steuerung, Hybrid-Modus, Takt-Optimierung) ist erst einmal ein Feature-Freeze: Es sind aktuell keine neuen Features geplant.

Mein Fokus liegt jetzt zu 100 % auf Fehlerbereinigung und Stabilität, um den Adapter zeitnah ins offizielle Stable-Repository von ioBroker zu bringen.

Testet den aktuellen Stand gerne ausgiebig! Anmerkungen, Anregungen oder auch einfach kurze "Läuft fehlerfrei"-Rückmeldungen sind jederzeit herzlich willkommen.

Jedes Feedback hilft uns enorm auf dem Weg zum Stable-Release.

Danke für euren fantastischen Support und das fleißige Testen!

0.22.6 (2026-11-06)

🐛 Bugfixes

• Cycle Optimization & Hardware Sync (main.ts):
  • Pre-Heating & Heating Limit Type Fix: Fixed strict type comparison bugs (boolean vs. number) when evaluating heatingLimit and VD1out (vd1). Previously, boolean state values caused isHeatingAllowedByLimit and vd1 to evaluate to false, which blocked pre-heating before hot water generation (raising heating_curve_parallel_offset to 35 °C), prevented the 10-minute base point reset, and skipped HUP voltage optimization.
  • Raw Data Fallbacks (rawValues / rawParams): Added direct fallbacks to raw heat pump telemetry and parameter arrays in runOptimizationSchedule so cycle optimization, HUP control, and heating limit checks remain fully functional even if individual datapoints (thresholdHeatingLimit, Mitteltemperatur, heatingLimit, VD1out, etc.) are disabled in the ioBroker object tree.
  • Hardware Out-of-Sync Verification: Enhanced syncConfigValue to verify target values against the live hardware parameter cache (currentRawParams), ensuring parameters are reliably written to the controller even if the local ioBroker state is disabled or out of sync with the heat pump.

0.22.5 (2026-11-06)

🔧 Maintenance & Compatibility

• Repository Compliance: Added missing multi-language translations (i18n) for all configuration dropdown menus (e.g. COP sources, PV modes) to meet strict ioBroker stable repository requirements.

0.22.4 (2026-11-06)

🐛 Bugfixes & Tweaks

• PV Surplus Management (pvManager.ts):
  • Cycle Completion & Reset Deadlock: Fixed a critical bug in initiateDeactivation when pv_finish_cycle was enabled: the inactive operating mode (e.g., hot water while heating is running) is now immediately reset to baseline[cite: 26, 28, 29]. This prevents infinite cycle loops where cycle optimization erroneously triggered forced 60 °C hot water runs at the end of a heating cycle[cite: 25, 28].
  • Target Reset vs. PV Max: Corrected cycle completion behavior so active compressor runs finish at normal baseline setpoints instead of continuing to heat to elevated PV boost targets with grid/battery power[cite: 26, 28, 29]. Added a dynamic timer to enforce the 10-minute minimum compressor run time before final reset[cite: 26].
  • Hysteresis Deadband & Timer Protection: Prevented the deactivation timer (pvStopTimer) from being aborted by minor meter/battery balancing fluctuations in the deadband between the stop threshold and start threshold[cite: 26, 27, 29].
  • Startup Recovery: Added baseline recovery during initPvManagement to clear orphaned boost targets left behind after an adapter update or reboot.
  • Input Parsing: Added parseConfigFloat to safely parse decimal values formatted with commas (e.g., "1,5") in the admin configuration[cite: 26, 29].
  • Direct Hardware Sync: Switched state updates to syncConfigValue for immediate, queue-safe synchronization via native TCP and Modbus[cite: 25, 26].

0.22.3 (2026-11-06)

• Notifications & Alarming:
  • Fixed an initialization bug where lastKnownErrorTimestamp and lastKnownOutageTimestamp were not set on adapter startup if the history remained unchanged, which previously caused the first genuine error or outage after a restart to be silently ignored.
  • Decoupled the 60-minute flow warning cooldown (lastFlowNotificationTime) from critical heat pump malfunctions so genuine fault alarms are never suppressed by preceding flow warnings.
  • Added language-independent outage code detection (codes 0, 1, 11, 18) alongside text-based fallbacks.
• ZIP Circulation Control:
  • Added a raw parameter fallback (currentRawParams) when backing up originalZipConfig to prevent timer schedules from being overwritten with null if the corresponding timer states are disabled in the object tree.
  • Fixed an issue in stopZipAndDeaeration where manually disabling Activate_Zip did not stop the hardware deaeration program (runDeaerate) by checking Virtual_ZIP_Status in addition to the trigger state.
• Stability & Helpers:
  • Wrapped the automated DTA backup cron job initialization (initAutoBackup) in a try/catch block to prevent startup crashes on malformed cron expressions.
  • Hardened safeClose in ModbusManager to cleanly terminate sockets even if a connection timeout occurs before the socket is marked as open.
  • Improved input validation in formatTimerSecondsToTime (guarding against negative values and NaN) and getNumber (supporting numeric strings).

0.22.2 (2026-11-06)

🐛 Bugfixes & Tweaks

• Cycle Optimization & PV Integration: Fixed an issue where the cycle optimization was blocked during an active PV boost. The adapter now correctly forces seamless transitions between heating and hot water (without compressor shutdown and anti-cycle delays) even when solar surplus is available. A new handshake mechanism ensures that PV target temperatures are immediately and safely restored after the cycle optimization resets the baseline idle defaults.

• PV Surplus Management & Compressor Optimization:

  • Fixed read-only datapoint errors in activateBoost and deactivateBoost (now correctly targeting temperature_hot_water_target).
  • Resolved baseline configuration mix-ups between fusspunkt and the heating parallel offset (heating_temperature).
  • Fixed the heating saturation check (isHzFull) to prevent premature boost revocation.
  • Implemented a seamless "PV-Boost Handshake" allowing cycle optimization to force hot water transitions even during active solar surplus without triggering anti-cycle compressor delays.

• ZIP Circulation & Timer Logic:

  • Fixed a bug where hot water timer slots (WW_MoSo_...) were mistakenly backed up and overwritten instead of circulation pump slots (Zirkulation_MoSo_...).
  • Improved time string conversions and state restoration robustness.

• COP Calculation & Virtual States:

  • Fixed a UTC timezone offset in daily rollovers so COP snapshots trigger precisely at local midnight.
  • Included defrosting cycles (WP_BZ_akt = 4) into the heating COP calculations and added clamping protection against negative energy deltas.
  • Added an in-memory object cache (ensuredObjects) to drastically reduce redundant database write calls.
  • Added a raw value fallback for total energy and thermal energy calculations if individual states are disabled in the object tree.

• Modbus & Raw Communication Stability:

  • Implemented a strict serial operation queue (mutex) with a 50ms release delay in ModbusManager to prevent TCP port 502 connection collisions.
  • Added a 30-second request timeout (AbortSignal.timeout) to DTA backups and corrected file naming for fallback paths (dta_history).
  • Expanded firmware version regex in updateManager to support F1., WWB, and smo firmware formats.
  • Added socket close event listeners and safe number roundings for raw write operations.

• Repository Compliance & Maintenance:

  • Added complete multi-language translations (i18n) for all configuration dropdown menus to meet strict ioBroker stable repository requirements.

  • Cleaned up unpublished ghost versions from the io-package.json news section.

  • Standardized the README changelog header format (## Changelog).

  • Repository Compliance: Added missing multi-language translations (i18n) for all configuration dropdown menus (e.g. COP sources, PV modes) to meet strict ioBroker stable repository requirements.

Interessant wenn kein LAN Kabel zur Verfügung steht

Hallo @tbsjah ich habe Deinen Adapter getestet (ohne modbus), da ich den nur lesend Use Case für Monitoring habe.
Sehr schön finde ich die konfigurierbaren Felder zum auslesen, da ältere Modelle oder Typen von WP bestimmte Werte nicht haben.
Bei mir muss der Modus zwingend read only sein, weil ich den Adapter nutze um WP Daten zu visualisieren, um Anlagenprobleme aus den Charts, welche ich aus den Daten erstelle, zu erkennen. (z. B. zu viele Takte, undichtes 3-Wege Ventil, Temperaturkurven...)
Teilweise stehen die WPs in Mietobjekten, da möchte man an der Konfiguration nichts ändern. Da wäre ein Schalter im Verbindungstab read-only nicht schlecht, aber das gleiche kann ja erreicht werden, wenn die Steuerungen in den anderen Tabs nicht aktiviert werden?
VG,
René

0.24.0 (2026-11-09)

🐛 Bugfixes & Tweaks

• Operating Mode & Write Protection (jsonConfig.json, main.ts):
  • Explicit Operating Mode Selection: Added a central "Operating Mode" selector in the Connection tab with color-coded status banners to clearly distinguish between Read-Only (Monitoring), Read & Write without Modbus (Native via Port 8889), and Read & Write with Modbus TCP (Hybrid RAM access).
  • Dynamic UI Locking: When "Read-Only" is selected, all write-related configuration tabs (Modbus, Idle Defaults, Cycle Optimization, HUP, ZIP, and PV Surplus) and their inputs are automatically grayed out and disabled. Selecting native write mode unlocks the optimization tabs while keeping the Modbus tab disabled.
  • Strict Backend Write Lock: Enforced a global hardware write lock in Read-Only mode across onReady, syncConfigValue, runOptimizationSchedule, and onStateChange (while keeping diagnostic functions like debug logging, raw dumps, and firmware checks active).
  • Automatic Config Migration: Existing installations are seamlessly migrated on startup to the matching operating mode based on their previously active Modbus and optimization settings.

0.23.2 (2026-11-07)

• COP & Efficiency Calculation (copManager.ts):
  • Isolated Counter Tracking: Introduced dedicated reference states for Total, Heating, and Hot Water counters (last_raw_power_* and last_raw_thermal_*). Each counter is now compared strictly against its own previous value, completely preventing cross-mode "ghost deltas" and astronomical COP spikes during cycle transitions.
  • Automatic Total-Delta Fallback: Added seamless fallback detection for controllers with firmware bugs (e.g., Novelan LAV) where mode-specific counters like energy_warmwater remain permanently at 0. If a specific counter reports a delta of 0 during an active cycle, the adapter automatically uses the live delta of the corresponding total counter (energy_total / thermalenergy_total) without requiring manual configuration workarounds.

0.23.1 (2026-11-07)

• COP & Efficiency Calculation Fix (copManager.ts):
  • Fixed Astronomical COP Values: Resolved a critical bug where the internal calculation logic switched between specific and total energy counters, causing massive "ghost deltas" and resulting in astronomical COP values (e.g., > 1000).
  • Restored Robust Routing: The adapter now strictly and safely relies on the continuous total counters (energy_total and thermalenergy_total). It calculates the delta over the polling interval and dynamically routes it into the Heating or Hot Water buckets based on the active operating state.
  • Note: Users facing the hardware bug where the heat pump does not track DHW power internally should select "External Object ID" in the adapter settings and link their energy_total datapoint as a workaround.

0.23.0 (2026-11-07)

🐛 Bugfixes & Tweaks

• Configuration & Baseline Logic:
  • Custom Heating Offset Baseline: Added a new configuration field in the "Idle Defaults" tab for the default heating target temperature offset (Parallelverschiebung)[cite: 10].
  • Preserved Baselines: The idle reset mechanism (main.ts) and the PV surplus manager (pvManager.ts) now respect this custom baseline (e.g., +1 K) instead of hard-resetting the offset to 0 K[cite: 7, 13]. This ensures that your manual baseline heating curve is perfectly preserved when returning from a PV boost or entering standby.
