[2.4.0] - 2026-05-30

Added

• HACS-compliant directory structure — all integration files now live under custom_components/solar_of_things/ as required by HACS. Installing via HACS or manual copy now works without any path adjustments.
• Brand asset — brand/icon.png added so the integration displays an icon in the HACS store and HA Integrations page.
• Sensor translation keys — all 14 sensors now use translation_key + has_entity_name = True, enabling future multi-language support and aligning with HA quality-scale best practices.

Fixed

• Missing API methods crash — number.py called api.set_battery_charge_limit(), api.set_battery_discharge_limit(), and api.set_grid_charge_limit() which did not exist in api.py. Interacting with any number slider raised an AttributeError. All three methods are now implemented.
• Select entity state mismatch — strings.json defined state keys (self_use, time_of_use, backup, grid_tie, off_grid) that did not match the actual API option strings (Utility First (USO), Solar First (SUB), etc.). State translations now match the real API values exactly.
• Device registry duplicates — sensors used (DOMAIN, station_id, device_id) as the device identifier while switches, selects, and numbers used the same tuple but in a different evaluation path. All device-level entities now use (DOMAIN, device_id) and station-level entities use (DOMAIN, station_id), eliminating duplicate device entries in the device registry.
• Re-auth crash on HA 2024.x — async_step_reauth declared entry_data as a required argument; HA 2024+ calls it with no argument. Made the parameter optional (entry_data: dict | None = None).

Changed

• manifest.json: added integration_type: hub (required since HA 2023.6), set homeassistant: "2023.6.0" minimum version, updated codeowners.
• hacs.json: updated homeassistant minimum to 2023.6.0, removed legacy zip_release / filename / domains fields incompatible with the new layout.
• strings.json / translations/en.json: corrected select state keys; added full sensor translation entries (previously absent).
• .gitignore: added graphify-out/ to exclude local knowledge-graph cache.

[2.3.3] - 2026-03-07

Fixed

• 404 Not Found on device settings — replaced incorrect settings endpoints with the correct remote-config API endpoints discovered from the live portal JS bundle:
  • Read: POST /apis/remote/device/configs/cache/get?deviceId=<id>
  • Write: POST /apis/remote/device/config/write?deviceId=<id>
• select.py — Operating Mode and Battery Priority selects now use real API keys (outputSourcePrioritySetting, chargerSourcePrioritySetting) with correct integer value mappings (USO/SUB/SBU, CSO/SNU/OSO).
• switch.py — all three switches map to correct API setting keys.

---

[2.3.2] - 2026-03-07

Fixed

• fetch_settings AttributeError — added class-level alias so both get_device_settings and fetch_settings work.
• Five missing control helper methods on SolarOfThingsAPI added (set_operating_mode, set_battery_priority, set_grid_charging, set_grid_feed_in, set_backup_mode).

---

[2.3.1] - 2026-03-07

Fixed

• Correct production AppID rBrTRfAPXz targeting https://solar.siseli.com. Previous release used the test AppID, causing "account error" for all real users.
• Password now MD5-hashed before transmission, matching portal behaviour.

---

[2.3.0] - 2026-03-07

Changed

• Authentication now uses User ID / Account instead of email address.

Fixed

• Fully working IOT Open Platform request signing (AES-128-CBC + HMAC-SHA256 + MD5).
• Correct API base URLs and login path.

---

[2.2.0] - 2026-03-06

Added

• Email + Password authentication with automatic token refresh.
• HA re-auth flow on token expiry.
• on_token_refreshed callback persists tokens to config entry.
• Legacy IOT-token mode preserved.

---

[2.1.1] - 2026-03-05

Added

• PR template for HACS default submission.

Changed

• hacs.json and manifest.json metadata updates.

---

[2.1.0] - 2026-02-26

Added

• Auto-discover all device IDs under a station via POST /apis/device/list.
• Optional device_id in config flow (blank = auto-discover all devices).

---

[2.0.0] - 2024-02-10

Added

• Full system control: number sliders, select dropdowns, switches.
• Settings API integration.

---

[1.0.0] - 2024-02-10

Added

• Initial release — monitoring sensors, config flow, multi-station support, Energy Dashboard compatibility.
