In "total" energy tracking mode, the stats endpoint queried smart plug
lifetime counters which can't be filtered by date range. Energy costs
and kWh stayed the same regardless of timeframe selection. Fall back to
per-print archive data when date filters are active.
parse_version() misclassified "0.2.2b4-daily.20260313" as a release
because the daily suffix made the last dot-segment ("20260313") contain
no alpha chars, bypassing prerelease detection. Strip -daily.YYYYMMDD
suffix before parsing so daily builds compare as their base beta version.
The migration that removes the UNIQUE constraint on smart_plugs.printer_id
used an exact substring match ("printer_id INTEGER UNIQUE") to detect the
constraint. Databases created with older SQLAlchemy versions may express
the constraint differently (quoted column names, table-level UNIQUE clause,
or separate UNIQUE indexes), causing the migration to silently skip.
Users hit "IntegrityError: UNIQUE constraint failed: smart_plugs.printer_id"
when assigning a second HA switch to a printer.
Replace the exact string match with regex pattern matching that handles
inline constraints, table-level UNIQUE(printer_id), quoted column names,
and standalone UNIQUE indexes.
Printers send many undocumented HMS codes (e.g. 0501_0002, 0501_0004,
0300_0001) that don't correspond to real errors — calibration status,
firmware state, etc. The frontend already filters these out (only shows
codes in ERROR_DESCRIPTIONS), but the backend notified for all codes
with severity >= 2, causing spurious email/push notifications on every
backend restart when a printer has active phantom codes.
Flip the logic: only send notifications for HMS codes with a known
description in the backend's HMS_ERROR_DESCRIPTIONS dictionary. Also
fix the log message to report the actual number of notifications sent,
not the pre-filter count.
Non-script HA entities (switch/light/input_boolean) on the printer card
always sent turn_on when clicked, which is a no-op when the switch is
already on. Now sends toggle for non-script entities so the badge click
actually changes the switch state. Script entities still use turn_on.
Also fix SmartPlugManager._get_plug_for_printer() using
scalar_one_or_none() which crashes with MultipleResultsFound when
multiple plugs are assigned to the same printer (e.g., Tasmota + HA
switch). Now fetches all plugs and returns the main non-script plug.
Add tests for both fixes: _get_plug_for_printer multi-plug handling
(5 tests) and canonicalFilamentType/filamentTypesCompatible/autoMatch
PA-CF equivalence (8 tests).
Bambu Lab firmware treats PA-CF, PA12-CF, and PAHT-CF as interchangeable,
but the print scheduler and filament override UI used exact string matching.
A 3MF requiring PA-CF wouldn't match PA12-CF in the AMS, leaving the
override dropdown disabled and preventing scheduler assignment.
Add a filament type equivalence system (both backend and frontend) so
these PA variants are treated as compatible in scheduler assignment,
AMS slot matching, force color match validation, and the override dropdown.
Also fix the "Force color match" checkbox click target being too wide
(entire row instead of just the checkbox/label) by changing flex to
inline-flex on the label element.
When all higher-priority slot-to-tray mapping methods failed (MQTT
mapping, print command mapping, queue mapping, color matching), the
internal usage tracker fell back to slot_id - 1 which can never reach
external spool IDs (254/255) or AMS-HT IDs (128+). Added position-based
resolution using sorted available tray IDs, matching the Spoolman fix
from PR #686.
Notify users when the first layer finishes printing so they can check
adhesion remotely. Triggers once per print when layer 2 begins
(layer_num >= 2, capped at <= 5 to handle reconnects). Includes a
camera snapshot attachment. Adds the on_first_layer_complete toggle
to all notification providers, with backend/frontend/i18n support
across all 7 locales.
When creating a virtual printer in proxy mode, the model was always set
to X1C because the frontend hides the model dropdown and the backend
used a hardcoded default. Now auto-inherits the model from the target
printer in proxy mode — on create, on target printer change, and on
mode switch to proxy.
Start, monitor, and stop drying sessions for AMS 2 Pro (n3f) and
AMS-HT (n3s) directly from the Printers page. Flame icon in AMS card
header opens a popover with filament-based temperature/duration presets
from BambuStudio. Live countdown status bar shows time remaining.
Backend: cache module_type from MQTT get_version, expose dry_time and
module_type in both WebSocket and REST paths, add supports_drying()
with firmware gating, add server-side guard on start_drying endpoint.
Frontend: drying button, popover with filament select + temp/duration
sliders, status bar, start/stop mutations. i18n for all 7 locales.
Supported: X1/X1C (fw 01.09+), P1P/P1S (fw 01.08+), H2D (fw 01.02.30+),
H2D Pro, X1E. Not supported: P2S, A1, A1 Mini, H2S, H2C.
Cloud credentials were stored globally — one Bambu Cloud account per
Bambuddy instance. When auth was enabled, any user logging into Cloud
overwrote everyone else's credentials. Credentials are now stored
per-user: each user gets their own independent Cloud login.
Also fixed cloud data endpoints (settings, fields, preset CRUD)
requiring settings:read/settings:update permissions instead of
cloud:auth — users who had "Cloud Auth" enabled but "Settings"
disabled couldn't load profiles after logging in.
The P2S firmware drops RTSP sessions after a few seconds with an I/O
error. The backend treated this as fatal, ending the MJPEG stream and
forcing the frontend through a full reconnection cycle. Added transparent
auto-reconnection: when ffmpeg's RTSP connection dies, it respawns
immediately and continues streaming MJPEG frames to the browser with
only a brief freeze (~1s). Up to 30 reconnections before giving up.
Three bugs: (1) home_flag bit 18 is set on all printers regardless
of connection type, so every ethernet-capable model showed the badge
even on WiFi. Replaced with wifi_signal heuristic — ethernet printers
with WiFi disabled report a hardcoded -90 dBm sentinel. (2) The lazy
import used `from app.utils.printer_models` which crashes with
ModuleNotFoundError in paho-mqtt's background thread (correct path:
backend.app.utils.printer_models). This killed the thread, causing
all printers to go stale after 60s and disconnect/reconnect in a
loop. (3) WiFi-only models excluded via model-based gating.
home_flag bit 18 is set on all printers regardless of hardware,
causing the ethernet badge to appear on WiFi-only models (A1, P1P,
etc.). The previous fix removed the feature entirely, so ethernet
printers lost their badge too.
Now only trusts bit 18 on models with an ethernet port (X1C, X1E,
P1S, P2S, H2D, H2D Pro, H2C, H2S). WiFi-only models always show
the WiFi signal badge.
The GET /api/v1/support/debug-logging endpoint returned 500 when the
database contained a timezone-aware enabled_at timestamp written by
0.2.2b3. The duration calculation mixed offset-aware and offset-naive
datetimes, raising TypeError. Strip tzinfo when reading the stored value.
Two bugs prevented bed cooldown notifications from working:
1. Stale temperature data: After print completion, the printer sends
partial MQTT updates without bed_temper, leaving the cached value
frozen at the end-of-print temperature. The monitor polled for 30
minutes seeing the stale value above threshold, then timed out.
Fix: send periodic pushall commands to force fresh temperature data.
2. Missing fields in provider create endpoint: on_bed_cooled and all 7
queue event toggles were omitted from the NotificationProvider
constructor, silently discarding user selections on create (update
worked fine via dynamic setattr).
Also added debug logging to the bed cooldown polling loop.
The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")
equal to the server's UTC offset. datetime.now() stored local time without a
timezone indicator, but the frontend's parseUTCDate() interpreted it as UTC.
Use datetime.now(tz=timezone.utc) consistently for storing, parsing, and
comparing the enabled_at timestamp.

datetimes, raising TypeError. Strip tzinfo when reading the stored value.
* Expanded link logic to accept a generic spool tag (spool_tag, tray_uuid, or tag_uid) and validate 16/32-char hex values, including rejection of all-zero tags. Added a new unlink endpoint that clears Spoolman extra.tag for a given spool ID.
* Updated the link validation expectation to match the new 16-or-32-hex rule. Added an integration test for the new unlink endpoint to verify extra.tag is cleared and success is returned.
* Updated the link API call to send spool_tag instead of tray_uuid. Added a new unlinkSpool API helper that calls the new backend unlink route.
* Switched modal data source from inventory spools to Spoolman unlinked spools so the list matches the backend response you shared. Updated the link action to call Spoolman link directly and use trayUuid or tagUid as the slot tag.
* Refactored Spoolman card behavior so actions render correctly across linked/unlinked cases, and added support for an Unlink from Spoolman button under Open in Spoolman. Final UI rule now hides Unlink for Bambu Lab filament and shows it only for non-Bambu linked spools.
* Added fallback slot-tag generation so untagged slots can still be linked/unlinked reliably and linked spool lookups work consistently across AMS, AMS-HT, and external trays. Wired a new unlink mutation and passed per-slot unlink callbacks into the hover card, with query invalidation for linked/unlinked spool caches after unlink.
* Added/updated the noTrayUuid message to reflect that either tray UUID or tag UID is required when no slot tag is available. This keeps error text aligned with the new tag fallback and modal behavior.
* Added noTrayUuid message in the other languages. The translation was done using Google Translate.
* Updated LinkSpoolModal tests to use Spoolman API instead of inventory API, with new UnlinkedSpool data structure and Select Spool UI text.
* Adds hashSerialToHex32, uses new function in getFallbackSpoolTag and updates all uses. This ensures we're generating a fallback spool tag using the printers serial number rather than the database ID for consistency.
* Removes 'import json' from unlink_spool and moves to the top of the file.
* Removes hasUnlinkedSpools and related references since it's no longer used
* Removes noTrayUuid from translations and references in components.
* Adds confirmation dialog before fully unlinking spool from Spoolman
* Adds unlinkConfrimTitle and unlinkConfirmMessage. All languages other than English were done using Google Translate
* Fixes unlink toast to use dedicated unlinkSuccess and unlinkFailed keys.
* Changes tag priority on spoolTag, fixes type error by adding non-null assertion to spoolTag
* Switches around tag_uid and tray_uuid on const trayTag

The debug logging banner displayed a negative elapsed time (e.g. "-60m -59s")

Sends persistent notifications to the HA dashboard using the existing
HA connection from Settings. Zero config — just select "Home Assistant"
as provider type. Users can forward notifications to mobile via HA
automations.
Large Hueforge 3MF files (~28 MB) can't be downloaded from the
printer's FTP server within the previous 120s max timeout, especially
during active printing. Added 180s and 300s timeout options to the
FTP settings dropdown.
Three interrelated bugs in AMS info field parsing caused AMS units
to appear on the wrong nozzle on H2D dual-nozzle printers:
1. Info field parsed as decimal instead of hex (BambuStudio uses
std::stoull with base 16)
2. Extruder ID extracted as 1-bit instead of 4-bit field (bits 8-11)
3. Partial MQTT updates replaced the full extruder map instead of
merging into it
home_flag bit 18 was incorrectly interpreted as "wired/ethernet
connection", causing the ethernet badge to always show — even on
printers without an ethernet port (e.g. A1, P1S). This hid the
WiFi signal indicator entirely.
Removed the wired_network field and ethernet badge UI. The WiFi
signal badge now shows correctly whenever the printer reports
signal strength.

Virtual printers in Queue mode now have an "Auto-dispatch" setting.
When enabled (default), prints start automatically — preserving current
behavior. When disabled, prints are added with manual_start so they
wait for manual dispatch from the queue UI.
The FTP upload skipped reading the server's "Transfer complete"
confirmation, sending the print command before the file was flushed
to the SD card. Now waits for the 226 response with a 60s timeout.
Checkbox selection + "Delete Selected" button in Settings > Filament
for both Spool Catalog and Color Catalog. Adds POST bulk-delete
endpoints and translations for all 7 locales.
P2S uses hardened steel rods, not carbon fiber. Move P2S from
carbon rod classification to new steel_rod category with its own
"Lubricate Steel Rods" / "Clean Steel Rods" maintenance tasks.
Add {eta} template variable showing wall-clock completion time
(e.g. "15:53" or "3:53 PM") to print_start, print_progress, and
queue_job_started notifications. Respects the user's time_format
setting (12h/24h). The existing {estimated_time} variable continues
to show duration ("1h 23m").
visibility into AMS spool assignments on printer cards without exposing
the full Inventory page (#635). The list_assignments endpoint now
requires this new permission instead of inventory:read. All default
groups (Administrators, Operators, Viewers) include it for backward
compatibility.
Closes#634
Files added to a project from the archive (status="archived") were
incorrectly counted in completed_prints and parts_progress stats.
Only status="completed" (actually printed) now counts toward completion.
All filament mapping dropdowns (single-printer, multi-printer, and
"Print to Any" model-based) showed only the base material type (e.g.
"PLA") without distinguishing subtypes like "PLA Basic" vs "PLA Matte",
making entries with different subtypes but same color look identical.
Backend: Add tray_sub_brands to available-filaments response and include
it in the dedup key so different subtypes of the same color appear as
separate entries.
Frontend: Show tray_sub_brands in FilamentMapping, FilamentOverride, and
PrinterSelector dropdowns, falling back to base type when unset. Add
traySubBrands field to LoadedFilament interface.
Two lazy-load bugs caused greenlet_spawn errors in the RFID auto-assign
flow:
1. create_spool_from_tray set spool.k_profiles=[] AFTER db.flush(),
but assigning to a relationship on a persistent object triggers a
lazy load (SQLAlchemy loads the current collection before replacing).
Moved initialization to BEFORE db.add().
2. spool.assignments was never initialized or eagerly loaded, so
db.add(SpoolAssignment) triggered a back_populates lazy load
outside the async greenlet. Added assignments=[] in create and
selectinload(Spool.assignments) in get_spool_by_tag.
Also added exc_info=True to error handlers for full tracebacks, and
19 new tests including greenlet regression tests that reproduce the
exact failure.
enum.StrEnum was added in Python 3.11, but the documented minimum is
3.10. Add a compatibility shim in backend/app/core/compat.py that falls
back to (str, Enum) on older versions. Updated all 5 import sites and
lowered pyproject.toml target-version to py310.
Bambu printers only support plain RSA key exchange ciphers
(AES256-GCM-SHA384, AES128-GCM-SHA256), but Python's OpenSSL 3.x
defaults exclude them in favor of forward-secrecy (ECDHE/DHE) only.
Add the RSA ciphers to the client SSL context so the TLS proxy can
connect to the printer's bind port (3002).
