chore: bump version to 0.1.5 [skip ci]

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

 # Bambu-Run
 
-Unlock richer data access and powerful customization capabilities for your Bambu Lab 3D printer.
+<p align="center">

+</p>
 
-Bambu-Run is a self-hosted web dashboard that tracks data of your Bambu Lab printer. It gives you:
-- Real-time monitoring and logging (temperatures, fan speeds, print progress etc) 
-- Automatic filament inventory tracking and usage monitoring system (AMS required)
-all running on hardware you own.
+Richer data, powerful customization for your Bambu Lab 3D printer.
 
-### Hardware Requirement
+Bambu-Run is a self-hosted web dashboard that gives you:
+- Real-time monitoring and logging (temperatures, fan speeds, print progress, and more)
+- Automatic filament inventory tracking and usage monitoring (AMS required)
 
-Recommend a raspberry pi, installed with Raspberry Pi OS (low cost running at the background) or an old PC/Laptop you probably never going to use again (install Linux).
-
-## Getting Started (Beginner Friendly)
-
-This guide walks you through setting up Bambu-Run on a **Raspberry Pi** from scratch. No prior server experience needed.
+All running on hardware you own.
 
 ### What You'll Need
 
-- A Raspberry Pi (3B+, 4, or 5) with Raspberry Pi OS installed and connected to your network
-- Your Bambu Lab printer on the **same local network** as the Pi
-- Your printer's **IP address**, **access token**, and **serial number** (we'll show you how to find these below)
-- A computer on the same network to SSH into the Pi
+Any always-on device works — a **Raspberry Pi** (3B+, 4, or 5) is ideal: beginner-friendly, runs Raspberry Pi OS out of the box, and quiet enough to tuck behind a desk. An old PC or laptop with Linux works too.
 
-### Step 1: Find Your Bambu Lab Account Credentials
+It runs quietly in the background 24/7, capturing every print, filament change, and AMS update the moment it happens. And the power bill? A Raspberry Pi 4 under light load draws about **5W**. That's roughly **43.8 kWh per year**, or the cost of **three cups of coffee**. ☕☕☕ Tuck it out of sight and forget it's there.
 
-Bambu-Run connects to your printer through the **Bambu Lab Cloud** using your account login — the same email and password you use for Bambu Handy or Bambu Studio.
+---
 
-You'll need:
-- **BAMBU_USERNAME** — Your Bambu Lab account email
-- **BAMBU_PASSWORD** — Your Bambu Lab account password
+## Table of Contents
 
-> **First-time login requires email verification.** Bambu Lab will send a 6-digit code to your email. You'll enter this code during Step 5a below. After that, you'll receive a token that skips verification on future startups.

+  - [Troubleshooting (Native)](#troubleshooting-native)
+- [Docker Setup](#docker-setup)
+- [Batch Importing Filament Colors and Filament Types](#batch-importing-filament-colors-and-filament-types)
 
-### Step 2: Connect to Your Raspberry Pi
+---
 
-From your computer, open a terminal (Mac/Linux) or PowerShell (Windows) and SSH into the Pi:
+## Native Setup (Recommended for Raspberry Pi)
+
+No Docker required. Works on any Raspberry Pi (including 32-bit Pi Model B) running Raspberry Pi OS with Python 3.10+.
+
+### What You'll Need
+
+- Raspberry Pi on your local network (Python 3.10+)
+- Bambu Lab printer
+- Bambu Lab account **email and password**
+
+### Clone and run setup.sh
 
 ```bash
-ssh pi@raspberrypi.local
-```
-
-> If `raspberrypi.local` doesn't work, use your Pi's IP address instead (check your router's admin page to find it).
-
-The default password is `raspberry` (you should change it after first login with `passwd`).
-
-### Step 3: Install Docker
-
-Docker lets you run Bambu-Run in a container — no need to install Python, databases, or anything else manually.
-
-Run these commands one at a time:
-
-```bash
-# Download and run Docker's install script
-curl -fsSL https://get.docker.com | sudo sh
-
-# Let your user run Docker without sudo
-sudo usermod -aG docker $USER
-```
-Installation issue? check installation methods for raspberry pi: https://docs.docker.com/engine/install/raspberry-pi-os/#installation-methods
-
-**Important:** Log out and log back in for the group change to take effect:
-
-```bash
-exit
-```
-
-Then SSH back in:
-
-```bash
-ssh pi@raspberrypi.local
-```
-
-Verify Docker is working:
-
-```bash
-docker --version
-```
-
-You should see something like `Docker version 27.x.x` — the exact number doesn't matter.
-
-### Step 4: Download and Configure Bambu-Run
-
-```bash
-# Clone the project
 git clone https://github.com/RunLit/Bambu-Run.git
 cd Bambu-Run
-
-# Create your configuration file
-cp .env.example .env
+bash setup.sh
 ```
 
-Now edit the `.env` file with your printer details:
+That's it! The script handles everything interactively, just answer the prompts. When it finishes, open `http://<ip>` from any device on same network.
+
+The script is safe to re-run at any time.
+
+---
+
+**What the script does**:
+
+- **Dependencies**: creates a Python virtual environment, installs all packages
+- **Credentials**: prompts for your **BambuLab Cloud account** email, password, and timezone; auto-generates a `DJANGO_SECRET_KEY`; writes `.env`
+- **Bambu Cloud auth**: runs `bambu_collector --once`; 
+  - Bambu Lab will send a 6-digit code to your email; check you email box and enter it when prompted; 
+  - the resulting token is saved to `.env` automatically; future restarts skip this step
+- **Dashboard login**: runs `createsuperuser`; choose a username and password for Bambu-Run web UI log in
+- **Services**: installs and starts two systemd services (`bambu-run-web` and `bambu-run-collector`), enables linger so they auto-start on boot
+- **Port 80**: sets an `iptables` redirect (80 to 8000) so you can reach the dashboard at a plain `http://<pi-ip>` with no port number; persisted via `iptables-persistent` across reboots. 
+
+---
+
+### Managing Bambu-Run
+
+All commands manage Bambu-Run encapsulated in `./native/bambu-run.sh`. Alternatively, you can do it yourself with systemctl commands.
+```bash
+./native/bambu-run.sh status    # service status
+./native/bambu-run.sh logs      # tail live logs (Ctrl+C to stop)
+./native/bambu-run.sh restart   # restart both services
+./native/bambu-run.sh stop      # stop everything
+./native/bambu-run.sh update    # git pull + pip install + migrate + restart
+```
+
+### Troubleshooting (Native)
+
+**Services die when SSH disconnects:** `sudo loginctl enable-linger $USER`
+
+**Services not starting:** `./native/bambu-run.sh status` and `./native/bambu-run.sh logs`
+
+**Auth errors / token expired:** Remove `BAMBU_TOKEN` from `.env` and re-run `bash setup.sh`
+
+**Uninstall:**
+```bash
+systemctl --user disable --now bambu-run-web bambu-run-collector
+rm ~/.config/systemd/user/bambu-run-{web,collector}.service
+systemctl --user daemon-reload
+```
+
+**Wipe everything and start over:**
+```bash
+# Stop and remove services
+systemctl --user stop bambu-run-web bambu-run-collector
+systemctl --user disable bambu-run-web bambu-run-collector
+rm ~/.config/systemd/user/bambu-run-{web,collector}.service
+systemctl --user daemon-reload
+
+# Remove port redirect (replace 80 with whatever port you chose during setup)
+sudo iptables -t nat -D PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8000 2>/dev/null || true
+sudo iptables -t nat -D OUTPUT -o lo -p tcp --dport 80 -j REDIRECT --to-port 8000 2>/dev/null || true
+sudo netfilter-persistent save 2>/dev/null || true
+
+# Delete repo — wipes venv, database, and .env
+cd ~
+rm -rf ~/Bambu-Run
+
+# Re-clone and run setup from scratch
+git clone https://github.com/RunLit/Bambu-Run.git
+cd Bambu-Run
+bash setup.sh
+```
+
+---
+
+## Docker Setup
+
+Requires Docker and Docker Compose installed. Assumes you already know how to get there.
+
+**Clone and configure:**
 
 ```bash
-nano .env
+git clone https://github.com/RunLit/Bambu-Run.git
+cd Bambu-Run
+cp .env.example .env
+# Edit .env: set BAMBU_USERNAME, BAMBU_PASSWORD, TIMEZONE
 ```
 
-Fill in your Bambu Lab account credentials from Step 1:
-
-```
-BAMBU_USERNAME=your_email@example.com
-BAMBU_PASSWORD=your_password
-```
-
-Optionally set your timezone (defaults to UTC):
-
-```
-TIMEZONE=Australia/Melbourne
-```
-
-> You can find your timezone name at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones
-
-To save and exit nano: press `Ctrl + X`, then `Y`, then `Enter`.
-
-### Step 5: Build and Start Bambu-Run
-
-First, build the container:
+**First-time auth** (Bambu Lab sends a 6-digit verification code to your email):
 
 ```bash
 docker compose build
-```
-
-This downloads all required software (takes a few minutes the first time).
-
-### Step 5a: First-Time Authentication
-
-The first time you connect, Bambu Lab requires email verification. You need to run the collector **interactively** (not in the background) so you can enter the 6-digit code.
-
-First, set up the database:
-
-```bash
 docker compose run --rm bambu-run python standalone/manage.py migrate --noinput
-```
-
-Then run the collector (this is what triggers Bambu Lab to send the verification email):
-
-```bash
 docker compose run --rm bambu-run python standalone/manage.py bambu_collector --once
+# Paste the printed token into .env as BAMBU_TOKEN=...
 ```
 
-You'll see output like:
-
-```
-BambuLab Authentication
-Authenticating as: your_email@example.com
-...
-EMAIL VERIFICATION REQUIRED
-A verification code has been sent to your email.
-Enter verification code:
-```
-
-1. Check your email for the 6-digit code from Bambu Lab
-2. Type the code and press Enter
-3. On success, you'll see a token printed:
-   ```
-   Authentication successful!
-   Token: eyJhbGciOiJIUzI1N...
-   TIP: Save this token to BAMBU_TOKEN env var to skip login next time
-   ```
-
-4. **Copy the full token** and paste it into your `.env` file:
-   ```bash
-   nano .env
-   ```
-   Add/uncomment the `BAMBU_TOKEN` line:
-   ```
-   BAMBU_TOKEN=eyJhbGciOiJIUzI1N...paste_full_token_here
-   ```
-
-> **Why save the token?** With the token saved, future container restarts authenticate instantly without needing email verification again. Without it, you'd need to repeat this step every time the container restarts.
-
-### Step 5b: Start Bambu-Run
-
-Now start everything in the background:
+**Start and create your dashboard login:**
 
 ```bash
 docker compose up -d
-```
-
-Check that it's running:
-
-```bash
-docker compose ps
-```
-
-You should see the `bambu-run` service with status `Up`.
-
-### Step 6: Create Your Login Account
-
-```bash
 docker compose exec bambu-run python standalone/manage.py createsuperuser
 ```
 
-You'll be prompted to choose a username, email (optional), and password. This is your login for the dashboard.
+Dashboard is at `http://<host-ip>:8000`.
 
-### Step 7: Open the Dashboard
+**Common operations:**
 
-On any device connected to your network (phone, tablet, computer), open a browser and go to:
-
-```
-http://raspberrypi.local:8000
-```
-
-> If that doesn't work, use your Pi's IP address: `http://<pi-ip-address>:8000`
-
-Log in with the account you just created. You should see your printer dashboard with live data flowing in.
-
-### Troubleshooting
-
-**"Cannot connect to printer" or no data showing:**
-- Make sure your printer is turned on and connected to the network
-- Check the logs: `docker compose logs -f`
-- If you see authentication errors, your token may have expired — re-run Step 5a to get a fresh token
-
-**"Verification code" or "401 Unauthorized" errors:**
-- Your `BAMBU_TOKEN` may have expired. Remove it from `.env` and re-run Step 5a
-- Make sure `BAMBU_USERNAME` and `BAMBU_PASSWORD` are correct in your `.env` file
-
-**"Cannot connect to Docker daemon":**
-- Did you log out and back in after Step 3? Docker group changes require a new session
-
-**Dashboard not loading in browser:**
-- Verify the container is running: `docker compose ps`
-- Try using the Pi's IP address instead of `raspberrypi.local`
-
-**Updating to a newer version:**
 ```bash
-cd ~/Bambu-Run
-git pull
-docker compose up -d --build
+docker compose logs -f                          # live logs
+docker compose down                             # stop (data preserved in volume)
+git pull && docker compose up -d --build        # update
 ```
 
-**Stopping Bambu-Run:**
+**Troubleshooting:** Auth errors → remove `BAMBU_TOKEN` from `.env` and re-run the auth step. No data → check `docker compose logs -f` for MQTT connection errors.

+
+## Batch Importing Filament Colors and Filament Types
+
+Bambu-Run ships with a full Bambu Lab color catalog under `docs/Bambu_Color_Catalog/` (one `.txt` file per filament sub-type, e.g. `PLA Basic.txt`, `PETG HF.txt`). Importing these populates the **Filament Colors** database so the dashboard shows proper color names instead of raw hex codes.
+
+### Adding your own colors
+
+Need a filament type that isn't in the bundled catalog? Create your own `.txt` file and point the importer at it.
+
+**File naming** — the filename determines the filament type and sub-type:
+```
+PLA Basic.txt     → type: PLA,  sub-type: PLA Basic
+PETG HF.txt       → type: PETG, sub-type: PETG HF
+ABS.txt           → type: ABS,  sub-type: ABS
+```
+
+**File format** — list each color on its own line, either as two rows (name then hex) or on the same line:
+```
+Jade White
+Hex:#FFFFFF
+
+Black Walnut    #4F3F24
+```
+
+Bambu Lab's website filament pages and their downloadable PDF catalogs are a reliable source — both list color names alongside hex codes you can copy directly.
+
+### When to run this
+
+Run the import **once after first setup** to seed the full color catalog in one go, rather than adding colors one by one. Run it again any time you want to add colors for a new filament type. Re-running is always safe — duplicates are detected and skipped automatically.
+
+### Import all colors (recommended)
+
+If the container is already running (`docker compose up -d`):
+
 ```bash
-docker compose down
+docker compose exec bambu-run python standalone/manage.py bambu_import_colors docs/Bambu_Color_Catalog/
 ```
 
-Your data is preserved in a Docker volume and will be there when you start it again.
+If the container is not running yet:
+
+```bash
+docker compose run --rm bambu-run python standalone/manage.py bambu_import_colors docs/Bambu_Color_Catalog/
+```
+
+### Import a file from your computer
+
+If your `.txt` color file lives on your Mac, Pi, or any machine running Docker (i.e. not inside the repo), copy it into the container first, then run the importer:
+
+```bash
+# Step 1 — copy the file from your machine into the container
+docker compose cp /path/to/your/PLA\ Basic.txt bambu-run:/tmp/
+
+# Step 2 — run the importer against the copied path
+docker compose exec bambu-run python standalone/manage.py bambu_import_colors /tmp/PLA\ Basic.txt
+```
+
+To import a whole folder of files at once:
+
+```bash
+# Step 1 — copy the folder
+docker compose cp /path/to/your/color_catalog/ bambu-run:/tmp/color_catalog/
+
+# Step 2 — import everything in it
+docker compose exec bambu-run python standalone/manage.py bambu_import_colors /tmp/color_catalog/
+```
+
+> **macOS tip:** You can drag a file from Finder into the terminal to paste its full path.
+
+### Import a single filament type
+
+To import only one sub-type from the bundled catalog (e.g. just PLA Basic):
+
+```bash
+docker compose exec bambu-run python standalone/manage.py bambu_import_colors "docs/Bambu_Color_Catalog/PLA Basic.txt"
+```
+
+### Preview before importing (dry run)
+
+Check what would be added without writing anything to the database:
+
+```bash
+docker compose exec bambu-run python standalone/manage.py bambu_import_colors docs/Bambu_Color_Catalog/ --dry-run
+```
+
+### What the output means
+
+```
+Processing: PLA Basic.txt  →  type='PLA'  sub_type='PLA Basic'
+  Parsed 40 color(s).
+  + 'Bambu Green' #009F87  (PLA / PLA Basic)
+  + 'Jade White'  #FFFFFF  (PLA / PLA Basic)
+  ...
+──────────────────────────────────────────────────
+  Created:              40
+  Skipped (duplicate):  0
+```
+
+- **Created** — new color entries added to the database
+- **Skipped (duplicate)** — already existed, not changed
+- **Skipped (no type)** — only shown if `--no-auto-create-filament-type` is used and the filament type isn't in the database yet

+"""
+Management command to import Bambu Lab filament color catalogs into the FilamentColor database.
+
+Parses .txt color catalog files (one file per filament sub-type) and creates or skips
+FilamentColor records. FilamentType records are auto-created as needed.
+
+Usage:
+    # Import a single file
+    python manage.py bambu_import_colors docs/Bambu_Color_Catalog/PLA\ Basic.txt
+
+    # Import all .txt files in a directory
+    python manage.py bambu_import_colors docs/Bambu_Color_Catalog/
+
+    # Dry-run (preview without writing)
+    python manage.py bambu_import_colors docs/Bambu_Color_Catalog/ --dry-run
+
+    # Fail instead of auto-creating missing FilamentType entries
+    python manage.py bambu_import_colors docs/Bambu_Color_Catalog/ --no-auto-create-filament-type
+
+File naming convention:
+    The stem determines filament type and sub-type:
+      PLA Basic.txt  → type=PLA,  sub_type=PLA Basic
+      PA6-GF.txt     → type=PA6,  sub_type=PA6-GF
+      ABS.txt        → type=ABS,  sub_type=ABS
+
+Supported file formats:
+    Format 1 (multi-line):    Format 2 (same-line / tab-separated):
+      Jade White                Black Walnut    #4F3F24
+      Hex:#FFFFFF               Rosewood        #4C241C
+
+    Hex values may appear as: Hex:#RRGGBB  Hex: #RRGGBB  #RRGGBB  RRGGBB
