+# Hersteller Tags - Deutsche Dokumentation
+
+## Überblick
+
+Das FilaMan NFC-System unterstützt **Hersteller Tags**, die es Filament-Produzenten ermöglichen, standardisierte NFC-Tags für ihre Produkte zu erstellen. Beim Scannen dieser Tags werden automatisch die notwendigen Einträge in Spoolman (Marke, Filament-Typ und Spule) erstellt, ohne dass eine manuelle Einrichtung erforderlich ist.
+
+## Funktionsweise der Hersteller Tags
+
+### Ablauf
+
+1. **Tag-Erkennung**: Wenn ein Tag ohne `sm_id` gescannt wird, prüft das System auf Hersteller Tag Format
+2. **Marken-Erstellung/Suche**: Das System sucht die Marke in Spoolman oder erstellt sie, falls sie nicht existiert
+3. **Filament-Typ-Erstellung/Suche**: Der Filament-Typ wird basierend auf Marke, Material und Spezifikationen erstellt oder gefunden
+4. **Spulen-Erstellung**: Ein neuer Spulen-Eintrag wird automatisch mit der Tag-UID als Referenz erstellt
+5. **Tag-Update**: Der Tag wird mit der neuen Spoolman Spulen-ID (`sm_id`) aktualisiert
+
+### Warum Hersteller Tags verwenden?
+
+- **Automatische Integration**: Keine manuelle Dateneingabe erforderlich
+- **Standardisiertes Format**: Konsistente Produktinformationen verschiedener Hersteller
+- **Lagerverwaltung**: Automatische Erstellung vollständiger Spoolman-Einträge
+- **Rückverfolgbarkeit**: Direkte Verbindung zwischen physischem Produkt und digitalem Inventar
+
+## Tag-Format Spezifikation
+
+### JSON-Struktur
+
+Hersteller Tags müssen eine JSON-Payload mit spezifischen Feldern enthalten, die **kurze Schlüssel** verwenden, um die Tag-Größe zu minimieren:
+
+```json

+# Manufacturer Tags - English Documentation
+
+## Overview
+
+The FilaMan NFC system supports **Manufacturer Tags** that allow filament producers to create standardized NFC tags for their products. When scanned, these tags automatically create the necessary entries in Spoolman (brand, filament type, and spool) without requiring manual setup.
+
+## How Manufacturer Tags Work
+
+### Process Flow
+
+1. **Tag Detection**: When a tag without `sm_id` is scanned, the system checks for manufacturer tag format
+2. **Brand Creation/Lookup**: The system searches for the brand in Spoolman or creates it if it doesn't exist
+3. **Filament Type Creation/Lookup**: The filament type is created or found based on brand, material, and specifications
+4. **Spool Creation**: A new spool entry is automatically created with the tag's UID as reference
+5. **Tag Update**: The tag is updated with the new Spoolman spool ID (`sm_id`)
+
+### Why Use Manufacturer Tags?
+
+- **Automatic Integration**: No manual data entry required
+- **Standardized Format**: Consistent product information across different manufacturers
+- **Inventory Management**: Automatic creation of complete Spoolman entries
+- **Traceability**: Direct link between physical product and digital inventory
+
+## Tag Format Specification
+
+### JSON Structure
+
+Manufacturer tags must contain a JSON payload with specific fields using **short keys** to minimize tag size:
+
+```json
+{
+    "b": "Brand/Vendor Name",
+    "an": "Article Number",
+    "t": "Filament Type (PLA, PETG, etc)",
+    "c": "Filament Color without # (FF5733)",
+    "mc": "Optional Multicolor Filament Colors without # (FF0000,00FF00,0000FF)",
+    "mcd": "Optional Multicolor Direction as Word (coaxial, longitudinal)",
+    "cn": "Color Name (red, Blueberry, Arctic Blue)",
+    "et": "Extruder Temp as Number in C° (230)",
+    "bt": "Bed Temp as Number in C° (60)",
+    "di": "Diameter as Float (1.75)",
+    "de": "Density as Float (1.24)",
+    "sw": "Empty Spool Weight as Number in g (180)",
+    "u": "URL to get the Filament with the Article Number"
+}
+```
+
+### Required Fields
+
+- **`b`** (brand): Manufacturer/brand name
+- **`an`** (article number): Unique product identifier
+- **`t`** (type): Material type (PLA, PETG, ABS, etc.)
+- **`c`** (color): Hex color code without #
+- **`cn`** (color name): Human-readable color name
+- **`et`** (extruder temp): Recommended extruder temperature in Celsius
+- **`bt`** (bed temp): Recommended bed temperature in Celsius
+- **`di`** (diameter): Filament diameter in mm
+- **`de`** (density): Material density in g/cm³
+- **`sw`** (spool weight): Empty spool weight in grams
+
+### Optional Fields

+- Provide accurate temperature recommendations
+- Include meaningful color names for user experience
+- Test tags with the FilaMan system before mass production
+
+## System Integration
+
+### Spoolman Database Structure
+
+When a manufacturer tag is processed, the system creates:
+
+1. **Vendor Entry**: Brand information in Spoolman vendor database
+2. **Filament Entry**: Material specifications and properties
+3. **Spool Entry**: Individual spool with weight and NFC tag reference
+
+### Fast-Path Recognition
+
+Once a tag is processed and updated with `sm_id`, it uses the fast-path recognition system for quick subsequent scans.
+
+## Troubleshooting
+
+### Common Issues
+
+- **Tag Too Small**: Use NTAG215 or NTAG216 for larger JSON payloads
+- **Missing Fields**: Ensure all required fields are present
+- **Invalid Format**: Verify JSON syntax and field types
+- **Spoolman Connection**: Ensure FilaMan can connect to Spoolman API
+
+### Validation
+
+The system validates:
+- JSON format correctness
+- Required field presence
+- Data type compliance
+- Tag size compatibility
+
+## Technical Details
+
+### Processing Algorithm
+
+1. Tag scan detects no `sm_id` field
+2. System checks for `b` (brand) and `an` (article number) fields
+3. `checkVendor()` creates or finds brand in Spoolman
+4. `checkFilament()` creates or finds filament type
+5. `createSpool()` creates new spool entry
+6. Tag is updated with new `sm_id`
+
+### Error Handling
+
+- Graceful fallback for network issues
+- Detailed logging for debugging
+- User feedback for failed operations
+- Retry mechanisms for temporary failures
+
+This system enables seamless integration of manufacturer filament products into the FilaMan ecosystem while maintaining data consistency and user experience.

+### Scale Technology
+
+#### Weight Stabilization
+
+The system uses multiple filters for precise measurements:
+
+```cpp
+// Moving Average Filter with 8 values
+#define MOVING_AVERAGE_SIZE 8
+// Low-Pass Filter for smoothing
+#define LOW_PASS_ALPHA 0.3f
+// Thresholds for updates
+#define DISPLAY_THRESHOLD 0.3f    // Display update
+#define API_THRESHOLD 1.5f        // API actions
+```
+
+#### Calibration Algorithm
+
+1. **System Pause**: All tasks are temporarily paused
+2. **Zero Setting**: Tare scale without weight
+3. **Reference Measurement**: 500g weight for 10 measurements
+4. **Calculation**: `newValue = rawValue / SCALE_LEVEL_WEIGHT`
+5. **NVS Storage**: Permanent value with verification
+6. **Filter Reset**: New baseline for stabilization
+
+#### Auto-Tare Logic
+
+```cpp
+// Conditions for Auto-Tare
+if (autoTare && (weight > 2 && weight < 7) || weight < -2) {
+    scale_tare_counter++;
+    if (scale_tare_counter >= 5) {
+        // Automatic zero setting
+        scale.tare();
+        resetWeightFilter();
+    }
+}
+```

+
+### API Integration
+
+#### Spoolman REST API
+
+FilaMan interacts with the following endpoints:
+
+```http
+GET  /api/v1/spool/          # List spools
+POST /api/v1/spool/          # Create new spool
+PUT  /api/v1/spool/{id}/     # Update spool
+
+GET  /api/v1/vendor/         # List vendors
+POST /api/v1/vendor/         # Create new vendor
+
+GET  /api/v1/filament/       # List filaments
+POST /api/v1/filament/       # Create new filament
+```
+
+#### Request Handling
+
+```cpp
+// Sequential API processing
+enum spoolmanApiStateType {
+    API_IDLE = 0,
+    API_PROCESSING = 1,
+    API_ERROR = 2
+};
+```
+
+Prevents simultaneous API calls and deadlocks.
+
+#### Weight Update Logic
+
+```cpp
+// Conditions for Spoolman update
+if (activeSpoolId != "" && 
+    weigthCouterToApi > 3 &&    // 3+ stable measurements
+    weightSend == 0 &&          // Not yet sent
+    weight > 5 &&               // Minimum weight 5g
+    spoolmanApiState == API_IDLE) {
+    updateSpoolWeight(activeSpoolId, weight);
+}
+```
+
+### Bambu Lab MQTT
+
+#### Connection Parameters
+
+```cpp
+// SSL/TLS Configuration
+#define BAMBU_PORT 8883
+#define BAMBU_USERNAME "bblp"
+
+// Topic Structure
+String topic = "device/" + bambu_serial + "/report";
+String request_topic = "device/" + bambu_serial + "/request";
+```
+
+#### AMS Data Structure
+
+```cpp
+struct AMSData {
+    String tray_id;
+    String tray_type;
+    String tray_color;
+    String tray_material;
+    String setting_id;
+    String tray_info_idx;
+    bool has_spool;
+};
+```
+
+#### Auto-Send Mechanism
+
+```cpp
+// After tag recognition
+if (bambuCredentials.autosend_enable) {
+    autoSetToBambuSpoolId = activeSpoolId.toInt();
+    // Countdown starts automatically
+    // Waits for new spool in AMS
+}
+```
+
+### WebSocket Communication
+
+#### Message Types
+
+```javascript
+// Client → Server
+{
+  "type": "writeNfcTag",
+  "tagType": "spool",
+  "payload": { /* JSON data */ }
+}
+
+{
+  "type": "scale",
+  "payload": "tare|calibrate|setAutoTare",
+  "enabled": true
+}
+
+// Server → Client
+{
+  "type": "heartbeat",
+  "freeHeap": 245,
+  "bambu_connected": true,
+  "spoolman_connected": true
+}
+
+{
+  "type": "amsData",
+  "data": [ /* AMS array */ ]
+}
+```
+
+#### Connection Management
+
+- **Auto-Reconnect**: Client-side reconnection
+- **Heartbeat**: Every 30 seconds for connection monitoring
+- **Cleanup**: Automatic removal of dead connections
+
+### Watchdog and Error Handling
+
+#### System Watchdog
+
+```cpp
+// WDT Configuration
+esp_task_wdt_init(10, true);  // 10s timeout, panic on overflow
+esp_task_wdt_add(NULL);       // Add current task
+```
+
+#### Error Recovery
+
+- **NFC Reset**: Automatic PN532 restart on communication errors
+- **MQTT Reconnect**: Bambu Lab connection automatically restored
+- **WiFi Monitoring**: Connection check every 60 seconds
