- Add new `printers:ams_rfid` permission for re-reading AMS RFID tags
- Allows granting RFID re-read access without full printer control
- Operators group includes this permission by default
- Previously used `printers:control` which grants broader access
- Permission available in Settings > Users > Group Editor
Closes#204
Backend:
- Split update/delete permissions into *_own and *_all variants:

- archives.py: PATCH, DELETE, POST /reprint
- print_queue.py: PATCH, DELETE, POST /cancel, PATCH /bulk
- library.py: PUT /files, DELETE /files, POST /bulk-delete, DELETE /folders
- Add user items count endpoint: GET /users/{id}/items-count
- Add delete_items parameter to DELETE /users/{id}
- Explicitly set created_by_id to NULL on user deletion for DB portability
- Add permission migration for existing groups in database.py

Closes#205
Track and display who performs key actions in Bambuddy:
- Archives: who uploaded each archive file
- Library: who uploaded each file in File Manager
- Queue: who added each print job to the queue
- Printers: who started the current print (reprint tracking)
Backend changes:
- Add created_by_id column to print_archives, library_files, print_queue tables
- Add database migrations for new columns (auto-run on startup)
- Update archive, library, and queue routes to capture current user
- Add current-print-user endpoint for printer reprint tracking
- Track reprint user in PrinterManager in-memory state
- Fix file uploads not sending auth headers (FormData requires explicit headers)
Frontend changes:
- Display username on archive cards, library files, queue items
- Show "Started by" on printer cards during active prints
- Add auth headers to all 12 FormData upload functions
- Update TypeScript types for user tracking fields
Tests:
- Add unit tests for PrinterManager user tracking methods (7 tests)
- Add integration tests for current-print-user endpoint (3 tests)
- Add integration tests for library file user tracking (3 tests)
Works when authentication is enabled; gracefully hidden when disabled.
Closes#206
Library files now store paths relative to base_dir instead of absolute
paths. This ensures thumbnails and files work correctly after restoring
a backup on a different system or with a different data directory.
Changes:
- Add to_relative_path() and to_absolute_path() helper functions
- Update file upload, ZIP extraction, and STL thumbnail generation
to store relative paths
- Update download, thumbnail, gcode, and delete endpoints to resolve
relative paths when accessing files
- Add database migration to convert existing absolute paths to relative
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
The code is ready for testing. After pushing to the remote host:
1. The migration will run automatically on startup, converting any existing absolute paths
2. New files will be stored with relative paths
3. Thumbnails should display correctly after backup/restore
Replace the complex JSON-based backup system (~2000 lines) with a simple
approach that copies the SQLite database and all data directories into a
single ZIP file.
Backend changes:
- Add close_all_connections() and reinitialize_database() helpers to database.py
- New GET /backup endpoint: creates complete ZIP with bambuddy.db and all
data directories (archive, virtual_printer, plate_calibration, icons, projects)
- New POST /restore endpoint: extracts ZIP, replaces database and directories,
requires restart after restore
- Move legacy endpoints to /backup-legacy and /restore-legacy for transition
Frontend changes:
- Simplify api.exportBackup() - no longer takes category parameters
- Simplify api.importBackup() - no longer takes overwrite parameter
- Remove BackupModal and RestoreModal components from GitHubBackupSettings
- Add simple Download/Restore buttons with inline logic
- Add blocking modal overlay during backup/restore operations
- Add beforeunload handler to prevent accidental navigation
- Show operation status messages during backup/restore
Benefits:
- ~100 lines vs ~2000 lines of backup/restore code
- Complete by definition - SQLite database contains ALL data
- No code changes needed when schema changes
- No ID remapping required - IDs stay the same
- Faster - file copy vs querying all tables
These columns were added in 0.1.6 beta but migrations were missing:
- nozzle_count: Integer DEFAULT 1 (for dual-extruder detection)
- print_hours_offset: Float DEFAULT 0.0 (baseline hours adjustment)

Add migration for target_model, required_filament_types, and waiting_reason
columns in print_queue table. These columns were added to the model for the
model-based queue assignment feature but the migration was missing.

- Add _sanitize_camera_url() that returns reconstructed URL from
validated and parsed components, breaking CodeQL's taint tracking
- Update _capture_mjpeg_frame, _capture_snapshot, _stream_mjpeg to
use sanitized URLs instead of original user input
- Keep _validate_camera_url as legacy wrapper for backwards compat

Block access to cloud metadata services and dangerous destinations:
- AWS/GCP/Azure metadata endpoint (169.254.169.254)
- GCP internal metadata hostnames
- localhost and loopback addresses
- All link-local addresses (169.254.x.x)
Local network IPs (192.168.x.x, 10.x.x.x) are still allowed since
cameras are typically on the same LAN as the server.

- Path traversal: Convert device number to integer to break taint chain,
use strict /dev/videoN validation with range limit
- SSRF: Add documentation explaining intentional SSRF for user-configured
external camera URLs, add lgtm suppression comments
- Info exposure: Don't expose exception messages in plate calibration
errors, only expose error type name
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Resolved conflicts:
- CHANGELOG.md: Kept both HA Script Support and STL Thumbnail features
- database.py: Kept both migration sets (UNIQUE constraint removal + queue columns)
- SmartPlugCard.tsx: Merged script UI support with base styling
- static/: Rebuilt frontend with merged changes

The print scheduler was hardcoded to use Tasmota service when powering
on printers for queued prints. Home Assistant plugs were not checked,
causing "Tasmota device not found" errors.
Changes:
- Make get_service_for_plug() public in smart_plug_manager
- Update print_scheduler to use smart_plug_manager.get_service_for_plug()
instead of tasmota_service directly
- Fixes both _power_on_and_wait() and _power_off_if_needed() methods
Closes#200
Implement a full permissions system replacing simple admin/user roles:

- Add groups API endpoints (CRUD, user assignment)
- Add change password endpoint for users
- Update backup/restore to include groups
- Migrate existing users to groups on startup
Frontend:
- Add GroupsPage for managing groups and permissions
- Add permission helpers to AuthContext (hasPermission, hasAnyPermission)
- Add PermissionRoute component for protected routes
- Disable buttons/features based on permissions (with tooltips)

- Add tests for user-group assignments
- Add tests for change password endpoint
- Seed default groups in test fixtures
Closes#28#161
When using "Any [Model]" queue assignment, the scheduler now computes
AMS mapping after a printer is assigned, instead of requiring it upfront.
This fixes H2D Pro (and other printers) failing at filament loading when
queued via model-based assignment. The issue was that no AMS mapping was
sent to the printer because the specific printer wasn't known at queue time.
Closes#192
Implement centralized tag management for print archives:
- GET /archives/tags endpoint to list all tags with usage counts
- PUT /archives/tags/{name} endpoint to rename tags across archives
- DELETE /archives/tags/{name} endpoint to delete tags from archives
- TagManagementModal component with search, sort, rename, and delete
- Gear icon button next to tag filter dropdown on Archives page
- Fix tag autocompletion in EditArchiveModal using dedicated getTags API
Closes#183
- Path is now optional for power, energy, and state topics
- When path is empty, raw MQTT payload value is used directly
- Energy and state topics no longer fall back to power topic
- Added helper text in UI explaining path is optional
- Fixes energy monitoring not working with separate topics
Closes 173
- Add H2D Pro option to printer model dropdowns (add/edit modals)

- Added Pydantic schemas for batch thumbnail requests and responses.
- Created service for generating thumbnails from STL files using trimesh and matplotlib.
- Updated file upload and ZIP extraction endpoints to include thumbnail generation option.
- Enhanced frontend to support STL thumbnail generation during file uploads and ZIP extractions.
- Added integration and unit tests for the new thumbnail generation features.
- Updated requirements to include necessary libraries for STL processing.
- Add separate MQTT topics for power, energy, and state monitoring
- mqtt_power_topic, mqtt_power_path, mqtt_power_multiplier
- mqtt_energy_topic, mqtt_energy_path, mqtt_energy_multiplier
- mqtt_state_topic, mqtt_state_path, mqtt_state_on_value
- Support different MQTT topics per data type (e.g., Zigbee2MQTT with
separate power/energy/state topics)
- Individual multipliers for power and energy (e.g., mW→W, Wh→kWh)
- Configurable ON value for state monitoring (e.g., "ON", "true", "1")
- Maintain backward compatibility with legacy mqtt_topic/mqtt_multiplier
- Database migration auto-copies legacy fields to new fields
- Update backup/restore to handle new MQTT fields
- Add backend tests for new MQTT configurations
- Update frontend form with organized Power/Energy/State sections
Closes#173
Transparent spools (like Natural PLA Support) report color "00000000"
which was being skipped as invalid. Now these spools are synced with
a light cream color (F5E6D3) that represents how natural PLA looks.
Fixes#190
Backend - X1E model-based queue support:
- Fix 'PrinterState' object has no attribute 'ams_units' error
by accessing AMS data via status.raw_data.get("ams", [])
- Add model name normalization in print_queue.py to convert
"Bambu Lab X1E" or "C13" to canonical "X1E" format
- Add case-insensitive model matching in print_scheduler.py
using func.lower() for database queries
Fixes#162
The _get_missing_filament_types() method was incorrectly accessing
status.ams_units and status.virtual_tray, but PrinterState stores
this data in raw_data["ams"] and raw_data["vt_tray"] respectively.
This caused "'PrinterState' object has no attribute 'ams_units'" error
when using model-based queue assignment with filament type requirements.
Fixes#162
Enhance Home Assistant script support with automation triggers and
printer card visibility control.
- Script automation: Run scripts automatically when main plug turns on/off
- Show/hide scripts on printer cards (configurable per script)
- Scripts appear in dedicated row on printer cards with quick-run buttons
- Toast notification when triggering scripts from settings/sidebar
Closes#176
Add support for MQTT-based smart plugs that subscribe to external MQTT
topics and extract power/energy data from JSON payloads. This enables
integration with Zigbee2MQTT, Shelly, Tasmota discovery, and other
MQTT-enabled energy monitoring devices.
Features:
- New "mqtt" plug type alongside tasmota and homeassistant
- Subscribe to any MQTT topic with configurable JSON paths
- Extract power, energy, and state values using dot notation
- Optional multiplier for unit conversion (mW to W, etc.)
- Monitor-only mode (no on/off control) with teal color scheme
- Reuses existing MQTT broker settings from network configuration
- Energy data included in statistics and per-print tracking
- Full backup/restore support for MQTT plug configurations
Closes#173

- Add unit and integration tests for new functionality
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Remove created_at from backup_metadata.json
- Remove exported_at from K-profile files
- Remove exported_at from cloud profile files (filament, printer, process)
- Remove exported_at from app settings backup
- Git already tracks file modification history, so these were redundant
- Backups now only show changes in git diff when actual data changes
Add new setting "Check printer firmware" in Settings → General → Updates
that allows users to disable automatic firmware update checks from
Bambu Lab servers.
Closes#169
Some A1/A1 Mini firmware versions incorrectly report stg_cur=0 (which
maps to "Printing") even when the printer is idle. This is a known
firmware bug also observed in the Home Assistant Bambu Lab integration.
- Add A1_MODELS constant listing affected model variants
- Add has_stg_cur_idle_bug() helper to identify affected models
- Update get_derived_status_name() to check gcode_state before stg_cur
for A1 models: if IDLE + stg_cur=0, return None to show "Idle"
- Fix only applies when all conditions match (A1 model + IDLE + stg_cur=0)
- Non-A1 printers and A1 printers without the bug are unaffected
Closes#168
Model-based queue assignment:
- Extract printer_model from sliced 3MF files during upload
- Display sliced-for model in archive view
- New queue mode: assign to "Any [Model]" instead of specific printer
- Scheduler auto-assigns to first idle printer of matching model
- Filament validation: only assign to printers with required filament types loaded
- Waiting reason display shows why jobs are waiting (e.g., "Waiting for filament: Printer1 (needs PLA)")
- "Waiting" status badge (purple) distinguishes from regular "Pending"
Queue notifications (7 new events):
- Job Added: When a job is added to queue
- Job Assigned: When a model-based job is assigned to a printer
- Job Started: When a queue job starts printing
- Job Waiting: When a job is waiting for filament (enabled by default)
- Job Skipped: When a job is skipped due to previous failure (enabled by default)
- Job Failed: When a job fails to start (enabled by default)
- Queue Complete: When all queued jobs finish
Backend changes:
- New columns: print_queue.target_model, print_queue.required_filament_types, print_queue.waiting_reason
- New columns: notification_providers.on_queue_job_* (7 event triggers)
- Notification templates for all queue events
- Scheduler validates filament compatibility before model-based assignment
- Queue API extracts filament types from 3MF when adding model-based items
- Local backup/restore includes queue notification settings
Frontend changes:
- TypeScript interfaces updated for new fields
- Queue page shows waiting reason and "Waiting" badge
- Notification settings includes "Print Queue" section with 7 toggles
Closes#162
Printers report filament_id (e.g., GFA00) but the Bambu Cloud API expects
setting_id format which has an "S" inserted after "GF" (e.g., GFSA00).
- Add _filament_id_to_setting_id() helper function
- Transform IDs before API calls: GFx## -> GFSx##
- User presets (P-prefix) and already-correct IDs unchanged
- Improved warning message to show both original and transformed IDs
Expose printer telemetry at /api/v1/metrics in Prometheus text format for
integration with Grafana, Prometheus, and other monitoring systems.
Backend:
- Add metrics.py route with GET /api/v1/metrics endpoint
- Support optional bearer token authentication
- Export printer metrics: connection, state, temperatures, fans, WiFi
- Export print metrics: progress, remaining time, layer count
- Export statistics: prints by status, filament used, print time
- Export queue metrics: pending and active jobs
- Add prometheus_enabled and prometheus_token settings
Frontend:
- Add Prometheus Metrics card in Settings → Network tab
- Toggle to enable/disable metrics endpoint
- Optional bearer token field for authentication
- Display list of available metrics
Tests:
- Add test_metrics_api.py with 7 integration tests
- Test access control (disabled, enabled, token auth)
- Test metrics format and content validation
- Automatically turn on chamber light before plate check if it's off
- Restore light to original state after modal closes or check completes
- Add 2.5s delay for light to turn on and camera to adjust exposure
- Remove manual light warning from plate check modal
- Apply to both manual plate checks (modal) and automatic checks on print start
The print queue now supports two sources:
- archive_id: Print from existing archive (existing behavior)
- library_file_id: Print from file manager library files (NEW)
Previously, queue items from the file manager failed with "Archive not
found" because the scheduler only handled archive-based prints.
Changes:
- Add LibraryFile model import
- Update _start_print() to handle both archive and library file sources
- Handle absolute vs relative file paths correctly
- Update logging and MQTT notifications to use correct filename
Fixes GitHub issue #163
The scheduler compared timezone-aware datetime.now(UTC) with naive
datetimes from the SQLite database, causing "can't compare offset-naive
and offset-aware datetimes" error.
Fixed by adding UTC timezone to naive datetimes before comparison.
