GREE Controller v0.5.5 - build and validation report

Scope

Version 0.5.5 builds on 0.5.4 with dedicated Night mode and Home Assistant/Sensors pages, compact unit-feature controls, and room-temperature refresh for disabled zones.

Implemented changes

• Night-mode settings moved out of application Settings into a dedicated Night mode page.
• Home Assistant connection, sensor aliases and integration access tokens moved to a dedicated Home Assistant / Sensors page.
• Settings now contains application/technical settings only.
• Unit-feature controls on device cards are smaller, centered and visually aligned with the other compact device controls.
• Disabled thermostat zones continue refreshing and showing room temperature while control commands remain disabled.
• Home Assistant sensor aliases are now presentation-only end-to-end: backend reads resolve aliases back to the original entity_id, settings are canonicalized, and zone/outdoor polling records the real entity ID.
• Outdoor temperature now falls back to the median outdoor reading from online GREE units when the configured Home Assistant outdoor sensor is unavailable.
• GREE optional capabilities are discovered from status properties (Lig, Quiet, Tur, Air, Blo, Health, SwhSlp) and persisted with each device.
• Supported unit features are shown in the Web UI and exposed as Home Assistant switches for panel light, Quiet, Turbo, X-FAN, Air, Health and Sleep.
• Night mode can use native GREE Sleep in the same command as the standby setpoint, fan limit and Quiet when the unit supports it.
• Home Assistant now exposes every controller zone as a full climate entity with Off / Auto (follow house mode) / Cool / Heat plus current and target temperature. Existing zone number/switch entities are retained.
• Decorative icons were removed from Settings block headers.
• Replaced the textual Connected/Disconnected label with a green/amber/red status dot in the top-left brand header.
• Fixed History filter layout so Zone/Device/Sensor and time-range controls keep equal heights and do not stretch after changing tabs.
• Reworked the Simulator into a Node-RED-style dotted flow board with connected live nodes for sensor input, thermostat target, decision, unit command and next event.
• Added configurable night mode (default 22:00-06:00): thermostat fan speed is capped during quiet hours and compatible units can be asked to keep Quiet enabled.
• Device cards now use Name / protocol instead of Rename and no longer show the fixed UDP port next to the IP address.
• Settings are split into visual blocks; the self-signed HA example uses a generic private address instead of an installation-specific address.
• Event/debug log retention is configurable and old rows are pruned automatically; the Events page can change retention and prune immediately.
• Home Assistant temperature sensors can have UI aliases; aliases replace raw entity IDs in history selectors, legends and custom-chart labels without changing stored entity IDs.
• Added a dedicated Web UI simulator page that visualizes thermostat/automation decisions as graphical blocks with hours, targets, demand, standby behavior, rule actions and upcoming events.
• Quick Thermostat cards on the dashboard can enable/disable a zone directly; the edit dialog is no longer required for this action.
• SQLite history housekeeping is tiered to chart resolution: full recent data, 10-minute buckets after 24 hours and 30-minute buckets after 7 days.
• Optional long-term InfluxDB archive supports both InfluxDB 1.x (database/basic auth) and 2.x (org/bucket/token), from persisted settings or environment variables.
• New samples are written to SQLite and InfluxDB in parallel when the archive is enabled.
• Maintenance backfills compacted legacy SQLite samples older than the configured Influx handoff age. A local row is deleted only after the Influx batch succeeds; archive failures keep the SQLite copy.
• History requests crossing the handoff age merge old InfluxDB data with recent SQLite data and fall back to SQLite when the archive query fails.
• Device commands are reduced to fields that actually changed. Optional GREE buzzer suppression uses Buzzer_ON_OFF/BuzzerCtrl; incompatible devices automatically fall back to normal frames and are remembered for the running process.
• Smart Fan now uses Low speed (WdSpd=1) when a zone is satisfied. The thermostat sends standby setpoint + Low fan + optional Quiet=1 in one GREE frame. If a unit rejects Quiet, the controller retries without it and remembers that capability fallback until restart; when demand resumes, controller-owned Quiet is released on the transition.
• Toast progress indicators have horizontal inset so they stay inside rounded toast corners.
• Settings can be exported/imported as JSON. Metrics, event logs and generated API-token records are preserved during import. Exported configuration contains configured secrets and must be protected.
• Optional on-screen debug overlay is available on every Web UI route, can be changed through /api/debug, shows controller events plus live HTTP method/path/status timing and can include sanitized decrypted GREE request/response payloads.
• /api/control-plan exposes house state, current zone decisions, schedules, upcoming transitions and automation rules/time events.
• The dashboard renders the control plan as blocks with current targets/demand and upcoming actions.
• Home Assistant integration now also exposes whole-house/per-zone plan sensors, writable per-zone target-temperature number entities and per-zone enable switch entities via the restricted integration API.

Validation performed in packaging environment

• node --check web/app.js.
• Python syntax validation for the Home Assistant integration and helper scripts.
• Shell syntax validation for all scripts/*.sh files.
• JSON validation for EN/PL language packs, PWA manifest, Home Assistant manifest and HA translations.
• EN/PL UI translation-key parity and literal UI translation-reference validation.
• SQLite schema execution plus tiered compaction and event-log retention tests.
• SQLite archive-selection query tests for device, zone and Home Assistant histories.
• Configuration-clear behavior verified to preserve metric history, event logs and API tokens.
• Version consistency checked for Cargo package, Cargo lock root package, README and Home Assistant manifest.
• Archive ZIP integrity and SHA-256 manifest are verified during final packaging.

Rust compiler note

The packaging environment does not contain rustc, cargo or rustfmt, so a Rust compile cannot be executed here. Rust unit tests cover unchanged-command filtering, history compaction, HA alias resolution, GREE outdoor fallback, night/native-Sleep decisions and combined standby command payloads; they cannot be executed in this packaging environment. The target LXC update/install scripts remain the authoritative compile gate and run:

cargo test --all-targets
cargo build --release

The update script must complete those commands before replacing the running binary.

2026-08-24 update

Implemented from the current source archive:

• Decimal thermostat input accepts both . and , in mobile/desktop UI via locale-independent parser and decimal keyboard hints.
• Notifications persisted in runtime settings with Pushover, Slack and Discord providers, test endpoint/button, two modes (problems, important), per-event cooldown, communication failure threshold and target-not-reached timeout.
• Device polling emits one offline anomaly after the configured consecutive-failure threshold and one recovery event when communication returns.
• Zone control tracks continuous demand and emits a zone.target_timeout anomaly once per demand episode when the target is not reached within the configured time.
• Automation dialog includes practical presets for high-temperature cooling, low-temperature heating, morning comfort and night power-off.
• Event log page has level/category filters and stronger visual separation by category/severity.
• Zone editor can copy thermostat tuning/profile settings from another zone without overwriting the destination zone identity, device assignment or HA entity.
• Language selector shows flags; theme selector shows compact theme icons.
• Home Assistant custom component includes icon.png and logo.png based on the existing project mark.
• New installs create a minimal environment file, keep SIMULATE=false and AUTO_SEED=false, and intentionally allow an empty application token. Existing env files remain untouched.
• Reverse-proxy support includes base-path routing, X-Forwarded-Prefix, prefix-aware UI/API/WebSocket/PWA assets and helper script health URLs.
• Removed permissive CORS and added basic browser security headers. Notification webhooks are HTTPS-only, host-restricted and do not follow redirects.
• Added docs/SECURITY.md and docs/REVERSE_PROXY.md.

History review: the supplied counts (28,133 GREE, 1,889 zone, 5,626 HA samples) are modest for the existing SQLite design. The current schema already has time/entity indexes, history bucketing, query limits, retention and compaction, so no database migration was added solely for these counts.

Validation performed in the build environment:

• node --check web/app.js - passed.
• JSON parsing of language files and web manifest - passed.
• bash -n scripts/install.sh - passed.
• Home Assistant icon files generated and verified as 256x256 RGBA PNG.
• Rust compilation was not executed because this execution environment does not contain cargo/Rust toolchain. Backend changes were therefore statically reviewed but require the normal project CI/build host to run cargo test/cargo build --release before deployment.
