# mc-webui

A lightweight web interface providing browser-based access to MeshCore mesh network.

[![Ask DeepWiki](https://deepwiki.com/badge.svg)](https://deepwiki.com/MarekWo/mc-webui)

> **Which version is this?** The [`VERSION`](VERSION) file always holds the version of the branch you are looking at: on `main` it matches the newest entry under [Releases](https://github.com/MarekWo/mc-webui/releases), on `dev` it carries a `-dev` suffix for the release being prepared. The Releases panel in the sidebar is repository-wide and always shows the newest published release, whichever branch you are browsing.

## Overview

**mc-webui** is a Flask-based web application providing browser-based access to MeshCore mesh network. It communicates directly with your LoRa device (via USB, BLE, or TCP) using the `meshcore` Python library, eliminating the need for SSH/terminal access. Tested on Heltec V3 and Heltec V4.

For detailed feature documentation, see the [User Guide](docs/user-guide.md).

## Quick Start

### Prerequisites

**1. Meshcore Device (tested on Heltec V4)**
- Flash the device at [https://flasher.meshcore.io/](https://flasher.meshcore.io/). Choose the `Companion USB` role (or `Companion BLE` if you plan to use Bluetooth).
- Configure the device with the Meshcore mobile app (from Google Play Store / App Store): Name, Location (optional), Preset

**2. Linux Server (or Raspberry Pi)**
- Docker and Docker Compose installed ([installation guide](docs/docker-install.md))
- Git installed (only needed for Option B: From Source)
- Supported architectures: `linux/amd64`, `linux/arm64`, `linux/arm/v7` (Raspberry Pi 2/3/4/5 all work)

**Important Notes:**
- Powered by direct meshcore library integration (v2 architecture)
- No manual directory setup needed - all data stored in `./data/` inside the project directory
- Uses a single-container architecture with a fast SQLite database

---

### Option A: Docker Hub (recommended)

The quickest way to get started — no git clone, no building required.

Available image tags:
- `mawoj/mc-webui:latest` — stable release (from `main` branch)
- `mawoj/mc-webui:dev` — latest development version (from `dev` branch)

Images are also mirrored to GitHub Container Registry: `ghcr.io/marekwo/mc-webui`

1. **Create a project directory**
    ```bash
    mkdir ~/mc-webui && cd ~/mc-webui
    ```

2. **Create `docker-compose.yml`**
 ```bash
 cat > docker-compose.yml << 'EOF'
 services:
 mc-webui:
 image: mawoj/mc-webui:latest
 container_name: mc-webui
 restart: unless-stopped
 ports:
 - "${FLASK_PORT:-5000}:${FLASK_PORT:-5000}"
 device_cgroup_rules:
 - 'c 188:* rmw'
 - 'c 166:* rmw'
 cap_add:
 - NET_ADMIN
 - NET_RAW
 volumes:
 - "${MC_CONFIG_DIR:-./data}:/data:rw"
 - "/dev:/dev"
 - "/var/run/dbus:/var/run/dbus"
 environment:
 - MC_SERIAL_PORT=${MC_SERIAL_PORT:-auto}
 - MC_DEVICE_NAME=${MC_DEVICE_NAME:-MeshCore}
 - MC_CONFIG_DIR=/data
 - MC_TCP_HOST=${MC_TCP_HOST:-}
 - MC_TCP_PORT=${MC_TCP_PORT:-5555}
 - MC_BLE_ADDRESS=${MC_BLE_ADDRESS:-}
 - MC_BACKUP_ENABLED=${MC_BACKUP_ENABLED:-true}
 - MC_BACKUP_HOUR=${MC_BACKUP_HOUR:-2}
 - MC_BACKUP_RETENTION_DAYS=${MC_BACKUP_RETENTION_DAYS:-7}
 - FLASK_HOST=${FLASK_HOST:-0.0.0.0}
 - FLASK_PORT=${FLASK_PORT:-5000}
 - FLASK_DEBUG=${FLASK_DEBUG:-false}
 - TZ=${TZ:-UTC}
 env_file:
 - path: .env
 required: false
 healthcheck:
 test: ["CMD", "curl", "-f", "http://localhost:5000/health"]
 interval: 30s
 timeout: 10s
 retries: 3
 start_period: 15s
 EOF
 ```

3. **Create `.env` file (optional)**

**In most cases, no `.env` file is needed!** The defaults work automatically:
    - `MC_SERIAL_PORT=auto` — auto-detects your USB device
    - `MC_DEVICE_NAME=auto` — auto-detects device name

If you want to set your timezone or override defaults:
    ```bash
    echo "TZ=Europe/Warsaw" > .env
    ```

<details>
 <summary>Troubleshooting: Multiple USB devices or detection fails</summary>

Check available serial devices:
    ```bash
    ls /dev/serial/by-id/
    ```

If you see multiple devices, add to your `.env`:
    ```bash
    MC_SERIAL_PORT=/dev/serial/by-id/usb-Espressif_Systems_heltec_...
    ```

</details>

4. **Verify Serial Device Permissions** (if needed)
    ```bash
    sudo usermod -aG dialout $USER
    # Log out and log back in for changes to take effect
    ```

5. **Start mc-webui**
    ```bash
    docker compose up -d
    ```

This will:
    - Pull the pre-built mc-webui image from Docker Hub
    - Create `./data/` directory structure automatically
    - Start the mc-webui container

6. **Verify installation**
    ```bash
    docker compose ps
    ```

The container should show `Up` status. Check logs if needed:
    ```bash
    docker compose logs -f
    ```

7. **Access the web interface**

Open your browser and navigate to:
 ```
 http://<your-server-ip>:5000
 ```

To find your server IP: `hostname -I | awk '{print $1}'`

8. **Initial Configuration (In Web UI)**
    - Main page loads with chat interface on "Public" channel
    - Wait for initial sync (1-2 minutes)
    - Optional: Enable manual contact approval in Contact Management

### Option B: From Source (Git Clone)

Choose this option if you want to modify the code, contribute, or run the `dev` branch.

1. **Clone the repository**
    ```bash
    cd ~
    git clone https://github.com/MarekWo/mc-webui
    cd mc-webui
    ```

2. **Create configuration file**
    ```bash
    cp .env.example .env
    ```

**In most cases, no changes are needed!** The defaults work automatically:
    - `MC_SERIAL_PORT=auto` - auto-detects your USB device
    - `MC_DEVICE_NAME=auto` - auto-detects device name from meshcli

Optionally edit `.env` to set your timezone: `TZ=Europe/Warsaw`

<details>
 <summary>Troubleshooting: Multiple USB devices or detection fails</summary>

Check available serial devices:
    ```bash
    ls /dev/serial/by-id/
    ```

If you see multiple devices, edit `.env` and set `MC_SERIAL_PORT` explicitly:
    ```bash
    MC_SERIAL_PORT=/dev/serial/by-id/usb-Espressif_Systems_heltec_...
    ```

</details>

3. **Verify Serial Device Permissions** (if needed)
    ```bash
    sudo usermod -aG dialout $USER
    # Log out and log back in for changes to take effect
    ```

4. **Build and run**
    ```bash
    python3 -m app.version freeze
    docker compose up -d --build
    ```

This will:
    - Download base images (Python, Alpine Linux)
    - Install the `meshcore` Python library
    - Create `./data/` directory structure automatically
    - Start the mc-webui container

5. **Verify installation**
    ```bash
    docker compose ps
    ```

The container should show `Up` status. Check logs if needed:
    ```bash
    docker compose logs -f
    ```

6. **Access the web interface**

Open your browser and navigate to:
 ```
 http://<your-server-ip>:5000
 ```

To find your server IP: `hostname -I | awk '{print $1}'`

7. **Initial Configuration (In Web UI)**
    - Main page loads with chat interface on "Public" channel
    - Wait for initial sync (1-2 minutes)
    - Optional: Enable manual contact approval in Contact Management

---

## Basic Usage

1. **View messages** - Main page shows chat history with auto-refresh every 10 seconds
2. **Send messages** - Type in the text field and press Enter (135 bytes for channels, 150 bytes for DM)
3. **Switch channels** - Use the dropdown in navbar
4. **Direct Messages** - Access via menu (☰) → "Direct Messages"
5. **Manage contacts** - Access via menu (☰) → "Contact Management"
6. **Console** - Access via menu (☰) → "Console" for MeshCore commands
7. **Search** - Access via menu (☰) → "Search" for full-text message search
8. **Settings** - Access via menu (☰) → "Settings" for DM retry and other configuration

For complete usage instructions, see the [User Guide](docs/user-guide.md).

## Android App

<table>
 <tr>
 <td width="200" align="center"><a href="images/android-wrapper-setup.jpg"><img src="images/android-wrapper-setup.jpg" width="180"></a></td>
 <td>
 A companion app that opens your own instance full screen — no address bar, its own icon in the app drawer. Everything still runs on your server; the app only displays it. 
 It is not distributed through Google Play. Download <a href="android/mc-webui-wrapper.apk"><code>android/mc-webui-wrapper.apk</code></a>, install it on the phone, and enter the address of your instance once (e.g. <code>http://192.168.1.100:5000</code>). 
 Full instructions — including the "unknown sources" and Play Protect warnings, and what the app can and cannot do — are in the <a href="docs/android-app.md">Android App guide</a>.

## Updating

### Docker Hub installation

Pull the latest image and restart:

```bash
cd ~/mc-webui
docker compose pull
docker compose up -d
```

To switch between stable and dev, change the image tag in `docker-compose.yml`:
- Stable: `image: mawoj/mc-webui:latest`
- Development: `image: mawoj/mc-webui:dev`

### From Source: Using the update script (recommended)

The easiest way to update mc-webui:

```bash
cd ~/mc-webui
./scripts/update.sh
```

The script automatically pulls changes, freezes the version, and rebuilds containers.

**Optional: Create a global alias for quick updates**

Add to your `~/.bashrc` or `~/.zshrc`:

```bash
alias mcupdate='~/mc-webui/scripts/update.sh'
```

Then reload your shell (`source ~/.bashrc`) and update anytime with:

```bash
mcupdate
```

### Manual update

If you prefer to run commands manually:

```bash
cd ~/mc-webui
git pull
python3 -m app.version freeze
docker compose up -d --build
```

The `python3 -m app.version freeze` command captures the current Git build (date + commit hash) for display in the app menu, underneath the release number from the `VERSION` file. Released versions are tagged `v<version>` and published at [Releases](https://github.com/MarekWo/mc-webui/releases); see [Versioning & Releases](docs/architecture.md#versioning--releases) for how a release is cut.

### Testing experimental features

The `dev` branch contains new features that are still being tested:

```bash
cd ~/mc-webui
git checkout dev
./scripts/update.sh
```

To return to the stable version:

```bash
cd ~/mc-webui
git checkout main
./scripts/update.sh
```

### Remote updates from web GUI (optional)

You can enable one-click updates directly from the mc-webui menu. This requires installing a small webhook service on the host machine.

**Install the updater service:**

```bash
cd ~/mc-webui
sudo ./scripts/updater/install.sh
```

The installer will:
- Create a systemd service `mc-webui-updater`
- Start a webhook server on port 5050 (localhost only)
- Enable automatic startup on boot

**Usage:**
1. Click the refresh button (↻) next to the version in the menu
2. If an update is available, an "Update" button appears
3. Click "Update" to trigger the update remotely
4. The app will automatically reload when the update completes

**Useful commands:**

```bash
# Check service status
systemctl status mc-webui-updater

# View logs
journalctl -u mc-webui-updater -f

# Uninstall
sudo ~/mc-webui/scripts/updater/install.sh --uninstall
```

**Security note:** The webhook listens only on localhost. The Docker container connects to it via the Docker bridge network.
