Project Aura v1.1.2

Project Aura v1.1.2

Release date: 2026-03-28

Highlights

• Web OTA update flow has been hardened significantly. Upload handling is more resilient, failure reporting is clearer, stale/incomplete attempts recover better, and the web UI now tracks OTA outcome more reliably.
• Added realtime AQI in the device UI, web state, MQTT payloads, and Home Assistant integration for a faster overall air-quality view.
• Home Assistant and MQTT integration were expanded with event mirroring, summary sensors, and improved discovery/control behavior.
• Added 12h / 24h clock display support, custom NTP server configuration, and more reliable timezone persistence.
• Diagnostics are easier to use: the log status chip opens the diagnostics page, alerts can be cleared from the screen without losing the underlying history, and diagnostics text is now localized.
• MQTT / Wi-Fi behavior was refined further, including less aggressive sensitivity to short network hiccups and cleaner dashboard wording in STA mode.

Notes

• OTA update keeps user settings.
• Web OTA is much improved, but on very noisy networks browser-upload OTA can still be sensitive to upload-path instability.

Release assets to publish

• OTA dashboard asset only:
  • project_aura_1.1.2_ota_firmware.bin

Internal note:

• Website installer files are hosted outside GitHub Release.

v1.1.1

Project Aura v1.1.1

Release date: 2026-03-16

Status

• This is the latest stable firmware before the public Project Aura release on MakerWorld.
• A lot has changed since v1.1.0; the points below summarize the main user-facing and stability improvements.

Highlights

• Web delivery has been reworked with embedded versioned assets for the Dashboard, Fan Control page, and Theme page, plus multiple transfer hardening improvements for difficult Wi-Fi environments.
• MQTT and Wi-Fi recovery behavior was refined for congested 2.4 GHz networks, with safer reconnect timing and reduced connection pressure.
• RTC support was expanded with DS3231 and PCF8523 autodetection, shared-address fault handling, clearer status visibility, and a manual RTC override mode.
• Sensor and peripheral robustness was improved for SEN66, SFA30, BMP58x/BMP388/BMP390, optional CO sensing, and DAC availability/fault reporting.
• Fan Control received multiple updates including HCHO support in auto mode, restored armed-auto behavior after reboot, synchronized timer presets, improved QR and direct-link access, and better web/UI consistency.
• The UI and web diagnostics flow were improved with a live system log screen, clearer OTA/update states, localized overlays, and more polished AP/STA dashboard behavior.
• Stability work also reduced steady-state memory drift and muted noisy low-level LCD panel I2C logs.

Notes

• OTA update keeps user settings.
• Recommended GitHub release asset:
  • project_aura_1.1.1_ota_firmware.bin

Internal note:

• Website installer files are hosted outside GitHub Release.

v1.1.0

Project Aura v1.1.0

Release date: 2026-02-22

Highlights

• New integrated web dashboard at /dashboard with tabs for Sensors, Charts, Events, Settings, and System.
• OTA firmware update from the web dashboard (Settings/System -> Update Firmware) using uploaded .bin files.
• Device UI now switches to a dedicated firmware update page during OTA to avoid a "frozen" screen impression.
• OTA flow hardened with upload lifecycle handling (begin/write/end/abort) and OTA slot size checks.

Notes

• OTA update keeps user settings.
• Full web installer flow still supports complete flashing (bootloader, partitions, app, filesystem).

Release assets to publish

• OTA dashboard asset only:
  • project_aura_1.1.0_ota_firmware.bin

Internal note:

• Website installer files are hosted outside GitHub Release.

Test 25.02.2026: verified dashboard + OTA update in STA and AP modes on device.

v1.0.9

Highlights

• Added SEN0466 CO sensor integration with PM4 fallback behavior and improved CO-related status handling.
• Added full DAC fan control subsystem (manual/auto modes, timers, auto-demand by sensor bands).
• Added DAC web control page (/dac) with live state, auto-config editing, and explicit START AUTO/STOP actions.
• Improved MQTT reliability (.local mDNS fallback/cache, stable host buffer handling) and UI diagnostics around LVGL stalls.
