The /filaments/ endpoint manages material type definitions (cost, temps,
density) but shares its name with the UI's "Filament" page which shows
the spool inventory (/inventory/spools/). This caused users to expect
the API to return their spool inventory.
Rename to /filament-catalog/ to make the distinction clear. No frontend
behavior change — these API methods are defined but unused in the UI.
Add a "Clear Errors" button to the HMS error modal that sends
clean_print_error via MQTT and locally clears hms_errors for
immediate UI feedback. Useful for dismissing stale print_error
values that persist after print cancellation or transient events.
The snapshot endpoint always used the internal printer camera even when
an external camera was configured. Now checks for external camera first,
matching the stream endpoint pattern. Also added retry logic (3 attempts,
2s delay) to MJPEG and RTSP stream generators so they reconnect on
timeout instead of silently ending the stream.
The Add Printer dialog previously required users to manually enter their
network subnet for scanning (defaulting to 192.168.1.0/24). Now the
backend detects available network interfaces and returns their subnets
via the /discovery/info endpoint. The frontend auto-selects the first
detected subnet and shows a dropdown when multiple subnets are available,
falling back to a text input if none are detected.
AMS Lite units (A1 series) have no weight sensor and always report 0%
fill level. When a spool is linked to Spoolman with weight data, use
Spoolman's remaining weight as a fallback. External spools also show
fill level from Spoolman data instead of always showing unknown.
Backend: Enrich GET /spoolman/spools/linked response with
remaining_weight and filament_weight alongside spool ID.
Frontend: Add getSpoolmanFillLevel() helper. Update regular AMS, HT
AMS, and external spool fill computations to use Spoolman fallback
when AMS reports 0%. Show "(Spoolman)" indicator in hover card when
fill data comes from Spoolman.
- Add HA_URL and HA_TOKEN environment variables for automatic HA
integration configuration in HA add-on deployments
- Environment variables always override database settings with
non-negotiable precedence; database values preserved for fallback
- Auto-enable integration when both env vars are set; partial config
(one env var) uses database enable state without auto-enabling
- Add centralized get_homeassistant_settings() function following
Spoolman pattern; replace direct database queries across codebase
- Add ha_url_from_env, ha_token_from_env, ha_env_managed fields to
AppSettings schema to inform frontend about configuration source
- UI shows read-only fields with lock icons and "(Environment Managed)"
labels when env-controlled; toggle shows auto-enable badge
- Add comprehensive test coverage: 9 integration + 8 unit tests
Closes#283
Users with local DNS can now add printers using hostnames like
printer.local or my-printer.home.lan. Updated backend schema
validation, database column width, frontend form patterns/placeholders,
and i18n labels across all locales. Added integration tests for
hostname and FQDN creation plus invalid hostname rejection.
- Remove 28 unused imports across 22 test files
- Prefix 4 unused local variables with _ in app code
(archives, bambu_mqtt, main) and remove 1 dead store
- Consolidate import/import-from in test_plate_detection.py
- Fix unreachable statement in test_archive_service.py
- Simplify redundant comparison in timelapse_processor.py
Resolves ~50 CodeQL py/unused-import, py/unused-local-variable,
py/import-and-import-from, py/unreachable-statement, and
py/redundant-comparison findings.
These modules were already imported at the top of each file.
Removes re-imports of re, json, zipfile, and logging from
inside functions in archive.py, library.py, main.py,
printers.py, support.py, and test_library_api.py.
Resolves all 30 CodeQL py/repeated-import findings.
Implement accurate per-filament usage tracking for Spoolman integration,
similar to OpenSpoolman v0.3.0. This replaces the previous single-spool
reporting with multi-material aware tracking.
Features:
- Parse G-code from 3MF files at print start to build per-layer,
per-filament cumulative extrusion maps
- Store tracking data in new `active_print_spoolman` database table
(survives server restarts for long prints)
- Report accurate partial usage when prints fail/cancel based on
actual layer progress and G-code data
- Add "Disable AMS Weight Sync" setting to prevent AMS percentage-based
weight estimates from overwriting Spoolman's granular tracking
- Add "Report Partial Usage for Failed Prints" toggle (only shown when
weight sync is disabled)
- Use Spoolman's filament density instead of defaults for mm-to-grams
conversion
- Prefer tray_uuid over tag_uid for spool identification
When a spool is already linked in Spoolman, the FilamentHoverCard now shows
"Open in Spoolman" button instead of "Link to Spoolman". This allows users
to quickly navigate to the spool's page in Spoolman for editing.
Changes:
- Add GET /api/v1/spoolman/spools/linked endpoint returning tag->spool_id map
- FilamentHoverCard shows "Open in Spoolman" when linkedSpoolId is set
- "Link to Spoolman" only shows when spool is not linked
- Fix unlinked spools detection to strip JSON quotes from empty tags
- Add toast notifications for link success/failure
- Invalidate linked-spools query after linking
- Add backend tests for linked spools endpoint
- Add frontend tests for LinkSpoolModal
Closes#210
The File Manager (Library) backend had no permission enforcement - endpoints were returning data to any authenticated user regardless of their group permissions.
Closes#224
Features:
- Add location filter for "Any {Model}" queue assignments
- Queue items can target a specific location (e.g., "Any X1C in Workshop")
- Location dropdown filter on Queue page to view jobs by location
- Scheduler considers location when assigning model-based jobs
Closes#220
## Summary
Address two critical security issues reported via GitHub Security Advisory:
1. Hardcoded JWT secret key allowing token forgery
2. Missing authentication on 77+ API endpoints
## Changes
### JWT Secret Key (backend/app/core/auth.py)
- Remove hardcoded secret "bambuddy-secret-key-change-in-production"
- Load secret from JWT_SECRET_KEY environment variable (recommended)
- Fall back to .jwt_secret file in data directory (auto-generated)
- Generate cryptographically secure 64-byte random secret if neither exists
- File is created with 0600 permissions for security
### API Authentication Middleware (backend/app/main.py)
- Add HTTP middleware that enforces auth on ALL /api/ routes
- When auth is enabled, every API request requires valid JWT or API key
- Only exempt routes that must be public:
- /api/v1/auth/status (check if auth enabled)
- /api/v1/auth/login (login endpoint)
- /api/v1/updates/version (version check)
- /api/v1/ws/* (WebSockets handle own auth)
### Test Updates
- backend/tests/conftest.py: Patch middleware's async_session for tests
- backend/tests/integration/test_ownership_permissions.py: Add missing
auth headers to requests that now require authentication
## Migration Notes
- Existing JWT tokens will be invalidated (users must re-login)
- Set JWT_SECRET_KEY env var in production for token persistence across restarts
- No database changes required
Fixes: GHSA-gc24-px2r-5qmf
Security: CWE-306 (Missing Authentication), CWE-321 (Hardcoded Crypto Key)
Closes GHSA-gc24-px2r-5qmf

Track and display who performs key actions in Bambuddy:

The 'tag' extra field is required in Spoolman for storing RFID/UUID
identifiers that link Bambu Lab spools to Spoolman entries. Previously,
users had to manually create this field in Spoolman, causing sync
failures for fresh installations.
Added ensure_tag_extra_field() method to SpoolmanClient that:
- Checks if the 'tag' field exists via GET /api/v1/field/spool/tag
- Creates it via POST if missing
The method is called automatically:
- On app startup when auto-connecting to Spoolman
- When user clicks "Connect" in Spoolman settings
Home Assistant smart plugs can now use separate sensor entities for
