Restricted Home Assistant control endpoints also accept generated integration tokens.\n\n### Local and GREE Cloud\nDevices use one API model and one command surface. `connection_type=local` is dispatched only to the existing LAN/UDP provider; `connection_type=gree_cloud` is dispatched only to the GREE Cloud provider. No automatic transport fallback is performed.\n\n### GREE Cloud security\nCloud passwords, REST/MQTT tokens, Authorization values and device cipher keys are never returned in normal API responses or Cloud diagnostics. MQTT uses TLS with certificate and hostname validation.\n\n### Energy\nGREE Cloud `ElcAll` and selected Home Assistant cumulative energy sensors are normalized to kWh and converted to consumption deltas before aggregation. Raw cumulative values are retained only as meter samples/baselines.\n\n### 0.14.21\nCode cleanup and small UX changes.\n\n### 0.14.20\nFixes the ARM cross-build bootstrap by removing the invalid xx-cargo version probe, prepares the target Rust standard library in a cacheable pre-source layer, shares dependency fetching across target architectures, and isolates compiled target caches per architecture while preserving DISTRO-selected Alpine/musl and Debian Trixie/glibc runtimes.\n\n### 0.14.19\nHome Assistant OCI builds now compile Rust for amd64/arm64 on the native build platform through xx cross-compilation, keep Cargo registry/target caches between builds, and send a smaller Docker context while preserving the selected Alpine (musl) or Debian Trixie (glibc) runtime. The Web UI also deduplicates the initial GREE Cloud runtime-status GET across the HTTP and WebSocket bootstrap renders.\n\n### 0.14.18\nShared Web UI CSS now uses generic reusable class names for segmented tabs, configuration layouts, chart cards, enable toggles, diagram primitives and Flow block categories; behavior and visual styling are unchanged.\n\n### 0.14.17\nHistory navigation now reuses the same segmented tab component as Flow / Schedules / Automations, with redundant History-specific tab CSS removed.\n\n### 0.14.16\nCustom Charts now expose saved-chart editing in the Web UI, public chart pages can switch history range through an optional hours override, and the standalone chart layout fits the viewport without vertical page scrolling.\n\n### 0.14.15\nHome Assistant add-on Custom Chart links now resolve the primary HA host IPv4 through Supervisor, support an explicit public_chart_base_url override, and enforce the fixed 8787 ingress/application port contract at startup and build time. Standalone bind/port behavior remains configurable.\n\n### 0.14.14\nShared Flow input Home Assistant sources now expose a dedicated entity search box separate from the selected entity_id, making large live entity catalogs easy to filter by name, ID and state.\n\n### 0.14.13\nHome Assistant add-on authentication is now hidden behind an automatic Supervisor status, manual URL/token fallback is unlocked only after a failed HA test, connection tests return a live sample entity reading, and Shared Flow input HA sources include searchable live entity suggestions.\n\n### 0.14.12\nThe Home Assistant add-on now uses the Supervisor Core API proxy and runtime SUPERVISOR_TOKEN automatically; standalone Home Assistant URL/token configuration is unchanged.\n\n### 0.14.11\nWeb UI icons now use a shared inline SVG set instead of font-dependent Unicode glyphs across navigation, dialogs, Flow, charts, controls and event categories for consistent cross-platform rendering.\n\n\n### 0.14.10\nNight mode and Home Assistant / Sensors standalone settings now use the full available page width, matching the other Web UI sections.\n\n### 0.14.9\nPower controls use an embedded SVG icon instead of a font-dependent Unicode glyph. Home Assistant room-sensor stale/error events identify the affected entity and zone, and historical event rows can recover that context from metadata.\n\n### 0.14.8\nRemaining Home Assistant and notification diagnostic errors no longer use device-transport 502 responses. Missing/invalid integration configuration returns 400, configured external dependency failures return 424, and 502 is reserved for Local/LAN GREE device communication.\n\n### 0.14.7\nHome Assistant energy-sensor discovery now returns an empty optional result when HA is not configured, uses 424 for configured external-dependency failures, and custom select popovers use their rendered height when positioning above a field.\n\n\n### 0.14.6\nFixes dynamic custom-select duplication in History → Energy and hides Energy history controls when no energy source is configured.\n\n### 0.14.5\nWeb UI single-choice controls now use one consistent custom dropdown, language packs are loaded on demand, and the dashboard outdoor temperature opens a 24-hour history modal.\n\n### 0.14.4\nHome Assistant connection tests validate only the configured server/API token and require no entity. `outdoor_entity_id` is the global Home Assistant outdoor-temperature sensor; zones can override it with `ha_outdoor_entity_id`. Room-temperature Home Assistant sensors remain configured per zone with `ha_entity_id`. Global/per-zone outdoor sensors are integrated with aliases, metrics/history and Visual Flow entity suggestions.\n\n### 0.14.2\nAdds independent vertical/horizontal swing controls across manual device control, thermostat zones, legacy automations, Visual Flow and Home Assistant zone climates. Swing is treated as an auxiliary one-shot unit setting and does not replace thermostat ownership.\n\n### 0.14.1\nAdds split/multisplit installation groups with shared energy and outdoor-temperature sources, multi-target energy charts with period comparison, cleaner Cloud status/alerts and safe MQTT cleanup after the last Cloud device is removed.\n\n### 0.14.0\nAdds first-class GREE Cloud MQTT status/control, reconnect/resubscribe lifecycle, Cloud diagnostics, per-device capabilities, Cloud/HA energy sources and energy-history aggregation while preserving the LAN transport contract.",
