The printer publishes partial deltas most of the time; the accumulator
merges each one onto whatever state it already has. When the printer
powers off, our cloud MQTT connection stays up (it's a persistent
session to Bambu's broker, not a socket to the printer), so nothing
signals the outage. When the printer reconnects and resumes its normal
partial updates, those deltas get merged onto the stale pre-outage
state — fields the delta doesn't mention (e.g. nozzle_temp) stay frozen
at their old values. Sending any command happens to trigger a full
report from the printer, which is why toggling the light "fixes" it.
Track the time of the last message per BambuPrinter instance. When a
new message arrives after a gap longer than
BAMBU_RUN_MQTT_RESYNC_GAP_SECONDS (default 90s), request a pushall
before processing it, forcing a complete state refresh instead of
trusting the partial delta to overwrite stale fields.
Dual-nozzle decoding only read extruder.info[1] for the left nozzle,
leaving the right nozzle to fall back on the legacy top-level
nozzle_temper/nozzle_target_temper fields. On the H2C that field
happens to always mirror the right extruder, but on the X2D it tracks
whichever nozzle is currently active — so during a left-only print the
"Right Nozzle" card showed the left nozzle's temperature.
Decode extruder.info[0] the same bit-packed way as the left side and
prefer it over the legacy field when present.
* Initial implementation of multi-printer support.
* Always show device dropdown and add bambu_diagnose for multi-printer troubleshooting.
* Add multi-AMS support: per-unit snapshot/usage tracking, grouped dashboard panels with real type labels, and dual-nozzle card UX fixes. Fixes a real-world AMS info-code parsing bug found by inspecting live H2C data.
* Add Vortek hotend rack tracking: per-SN registry with slot mapping confirmed against live MQTT capture, plus a fallback for non-inductive nozzles (e.g. H2C's fixed left nozzle) shown read-only without fabricated identity. New dashboard card hides entirely on printers with no Vortek/nozzle-info data at all.
Schema (migration 0004):
- PrinterMetrics: nozzle_temp_left, nozzle_target_temp_left,
nozzle_diameter_left, nozzle_type_left (all nullable)
- Filament: ams_unit_id (nullable int), ams_type (AMS/AMS 2 Pro/AMS HT)
- AMS_INFO_TO_TYPE map and AMS_TYPE_CHOICES on models
Parser (mqtt_client.py):
- Decode bit-packed temps from device.extruder.info[] for left/right nozzle
- Emit per-nozzle fields in get_snapshot(); legacy keys mirror right side
- AMS unit type from info code per unit dict
Collector (bambu_collector.py):
- Write left-nozzle fields to PrinterMetrics
- Set ams_unit_id + ams_type on Filament records
- Fix: poll MQTTClient.connected before pushall (not BambuPrinter._connected)
- Add 5s post-pushall wait in --once mode so response arrives before collect
Views: API and dashboard include left-nozzle series; is_dual_nozzle flag
Templates: dual-nozzle cards + chart; AMS-type badge + filter on filament list
Charts: left nozzle temp chart with conditional render
Forms: fix tray_id max=3 → max=15; add ams_unit_id, ams_type fields
