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### 0.14.10\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.",

Raw cumulative values are retained only as meter samples/baselines.\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.",

 # Changelog

+## 0.14.11
+
+- Replaces font-dependent Unicode glyphs used as Web UI icons with a shared inline SVG icon set.
+- Covers navigation, theme/refresh controls, dialogs, menus, Flow editor/statuses, chart zoom/fullscreen controls, thermostat/device +/- controls, custom-select checks/chevrons and event-category icons.
+- Leaves semantic text symbols such as `°C`, `±`, comparison operators, mathematical multiplication and Flow expression notation as text.
+- Keeps the 0.14.10 full-width Night mode and Home Assistant / Sensors layout fix.
+
 ## 0.14.10

 - Makes the standalone Night mode and Home Assistant / Sensors forms use the full available page width, matching the other application sections on desktop and responsive layouts.
