Features & Fixes

Frontend

• Updated frontend bundle**

• Combined Charts

• Plant-Buddy ( AI plant analytics )

• 20 Total Themes

• Lite Version added ( can be changed over Settings ) and will be ask you on on Page load. ( IF YOUR "CACHE-DELETE"IS NOT ENABLED YOU NEED TO WAIT FOR IT )

Bug Fixes

• Action Flows for Modes adjustments in VPD Perfection , VPD Target & Closed Enviorment
• Reservoir autofill: correctly stops filling below the maximum level
• Test fixes: corrected deadband behavior in tests
• Smart deadband: FineTune_vpd event enabled within the deadband to keep devices idle
• Adaptive cooldown: tests updated for new default adaptiveCooldownEnabled=false
• ORP calculation: initial calculation added at sensor startup, removed faulty _oxi handling

New Features

20 Plant Species with Species-Specific VPD Maps

• 20 plant species with species-specific growth stages and VPD maps
• Dynamic PlantStage selection that adapts based on species
• New HA entities: select.ogb_plantspecies_<room> per room
• Dynamic Fan Control Based on Temp

Centralized Cooldown Management

• New OGBgcdManager centralizes all cooldown logic
• Improved performance and consistency for device actions

Hydro System Enhancements

• Reservoir autofill safety: no filling below max_fill_level
• Pump label alignment: consistent labeling across the hydro system
• More robust event handling: ReservoirManager now processes both dictionaries and objects

Centralized Configuration Management

• Unified configuration.yaml management with automatic backups
• Preservation of !include directives during configuration updates

Tests

• Capability calibration: 17 tests covering the full calibration workflow including response curves
• Long-term integration: 3 new tests for multi-day simulations (plant growth, 30-day reservoir, 14-day duty cycle)
• Reservoir autofill: test for repeated filling in long-term scenarios
• Total: 359 logic tests passing

Capability Calibration System (Response Curve Profiling)

A comprehensive new calibration system for device capabilities:

• Two calibration modes: On/Off for simple devices, and a 4-step response curve (25%, 50%, 75%, 100%) for dimmable devices
• Automated workflow: baseline (60s) → effect stages → cooldown (30s)
• Safety abort: automatic stop at temperature > 35°C, humidity < 30%, CO₂ > 2500 ppm
• Persistent results: delta_per_min for switches, slope_per_percent + r² for dimmable devices
• Console commands: cap_calibrate <cap>, cap_cal_status, cap_cal_stop
• Brute-force shutdown: hard_turn_off() reliably switches off all devices (including dimmable fans)

Documentation

• CALIBRATION.md: fully revised with calibration workflow, event system, and response curve results
• TENT_CONTROL_MODES.md: updated with new modes (Closed Environment, Script Mode) and service documentation

Technical Improvements

• Event-based device control: three new events (CalibOff, CalibOn, CalibStart) for precise control
• Datastore corruption repair: automatic repair of broken states on boot
• HA select entity sync: tentMode changes reliably propagated to HA entities
• Async cooldown handling: all cooldown methods are now asynchronous for better performance

Full Changelog: v1.4.2.5...v1.4.2.6
