+
+## Manufacturer Tags
+
+### Overview
+
+Manufacturer tags allow filament producers to provide pre-configured NFC tags that automatically create all necessary entries in Spoolman.
+
+### Getting Started with Manufacturer Tags
+
+1. **Scan Tag**
+   - Place spool with manufacturer tag on the scale over the NFC reader
+   - If reading fails: Reposition spool slightly (not completely at the edge)
+   - System automatically recognizes manufacturer format
+
+2. **Automatic Creation**
+   - **Brand** created in Spoolman (if not present)
+   - **Filament type** created with all specifications
+   - **Spool** automatically registered
+
+3. **Future Scans**
+   - After initial setup, tags use fast-path system
+   - Immediate weight measurement without re-setup

+
+### 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();
+    }
+}
+```
+
+### NFC Technology
+
+#### PN532 Communication
+
+- **Interface**: I2C at 400kHz
+- **IRQ Pin**: Interrupt-based tag detection
+- **Reset Handling**: Automatic recovery from communication errors
+- **DIP Switches**: Must be set to I2C mode (00)
+
+#### NDEF Implementation
+
+```json
+// FilaMan Spoolman Format (with sm_id)
+{
+  "sm_id": "123",
+  "color": "#FF5733",
+  "type": "PLA", 
+  "brand": "Example Brand"
+}
+```
+
+#### Manufacturer Tag Schema
+
+Compact JSON format for storage efficiency:
+
+```json
+{
+  "b": "RecyclingFabrik",           // brand
+  "an": "FX1_PLA-S175-1000-RED",  // article number
+  "t": "PLA",                      // type
+  "c": "FF0000",                   // color (hex without #)
+  "cn": "Red",                     // color name
+  "et": "210",                     // extruder temp
+  "bt": "60",                      // bed temp
+  "di": "1.75",                    // diameter
+  "de": "1.24",                    // density
+  "sw": "240",                      // spool weight
+  "u": "https://www.yoururl.com/search?q=" // URL used vor Brand Link and Filament Link
+}
+```
+
+### Display System
+
+#### OLED Architecture (SSD1306)
+
+- **Resolution**: 128x64 pixels monochrome
+- **Areas**:
+  - Status bar: 0-16 pixels (version, icons)
+  - Main area: 17-64 pixels (weight, messages)
+- **Update Interval**: 1 second for status line
+
+#### Icon System
+
+Bitmap icons for various states:
+
+```cpp
+// Status Icons (16x16 pixels)
+- icon_success: Checkmark for successful operations

+- icon_transfer: Arrow for data transmission
+- icon_loading: Loading circle for ongoing operations
+
+// Connection Icons with strikethrough indicator
+- wifi_on/wifi_off: WLAN status
+- bambu_on: Bambu Lab connection
+- spoolman_on: Spoolman API status
+```
+
+### 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

+    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",
