RemoteTerm for MeshCore

Backend server + browser interface for MeshCore mesh radio networks. Attach your radio over serial, and then you can:

• Send and receive DMs and GroupTexts
• Cache all received packets, decrypting as you gain keys
• Monitor unlimited contacts and channels (radio limits don't apply -- packets are decrypted server-side)
• Access your radio remotely over your network or VPN
• Brute force hashtag room names for GroupTexts you don't have keys for yet

Warning: This app has no authentication. Run it on a private network only -- do not expose to the internet unless you want strangers sending traffic as you.

Disclaimer

This is entirely vibecoded slop -- no warranty of fitness for any purpose. It's been lovingly guided by an engineer with a passion for clean code and good tests, but it's still mostly LLM output, so you may find some bugs.

If extending, read the three CLAUDE.md files: ./CLAUDE.md, ./frontend/CLAUDE.md, and ./app/CLAUDE.md.

Requirements

• Python 3.10+
• Node.js 18+ (for frontend development only)
• UV package manager: curl -LsSf https://astral.sh/uv/install.sh | sh
• MeshCore radio connected via USB serial

Find your serial port:

#######
# Linux
#######
ls /dev/ttyUSB* /dev/ttyACM*

#######
# macOS
#######
ls /dev/cu.usbserial-* /dev/cu.usbmodem*

######
# WSL2
######
# Run this in an elevated PowerShell (not WSL) window
winget install usbipd

# restart console

# find device ID (e.g. 3-8)
usbipd list

# attach device to WSL
usbipd bind --busid 3-8

Quick Start

This approach is recommended over Docker due to intermittent serial communications issues I've seen on *nix systems.

The frontend is pre-built -- just run the backend:

git clone https://github.com/jkingsman/Remote-Terminal-for-MeshCore.git
cd Remote-Terminal-for-MeshCore

uv sync
uv run uvicorn app.main:app --host 0.0.0.0 --port 8000

The server auto-detects the serial port. To specify manually:

MESHCORE_SERIAL_PORT=/dev/ttyUSB0 uv run uvicorn app.main:app --host 0.0.0.0 --port 8000

Access at http://localhost:8000

Note: WebGPU cracking requires HTTPS when not on localhost. See the HTTPS section under Additional Setup.

Docker

Warning: Docker has intermittent issues with serial event subscriptions. The native method above is more reliable.

docker run -d \
  --device=/dev/ttyUSB0 \
  -v remoteterm-data:/app/data \
  -p 8000:8000 \
  jkingsman/remote-terminal-for-meshcore:latest

Development

Backend

uv sync
uv run uvicorn app.main:app --reload

# Or with explicit serial port
MESHCORE_SERIAL_PORT=/dev/ttyUSB0 uv run uvicorn app.main:app --reload

Frontend

cd frontend
npm install
npm run dev      # Dev server at http://localhost:5173 (proxies API to :8000)
npm run build    # Production build to dist/

Run both the backend and npm run dev for hot-reloading frontend development.

Code Quality

Please lint, format, and quality check your code before PRing or committing. At the least, run a lint + autoformat + pyright check on the bakend, and a lint + autoformat on the frontend.

But how?

# python
uv run ruff check app/ tests/ --fix  # lint + auto-fix
uv run ruff format app/ tests/       # format (always writes)
uv run pyright app/                  # type checking

# frontend
cd frontend
npm run lint:fix                     # esLint + auto-fix
npm run format                       # prettier (always writes)

Configuration

Variable	Default	Description
MESHCORE_SERIAL_PORT	(auto-detect)	Serial port path
MESHCORE_SERIAL_BAUDRATE	115200	Baud rate
MESHCORE_LOG_LEVEL	INFO	DEBUG, INFO, WARNING, ERROR
MESHCORE_DATABASE_PATH	data/meshcore.db	SQLite database path
MESHCORE_MAX_RADIO_CONTACTS	200	Max recent contacts to keep on radio for DM ACKs

Additional Setup

HTTPS (Required for WebGPU Cracking outside localhost)

WebGPU requires a secure context. When not on localhost, serve over HTTPS:

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj '/CN=localhost'
uv run uvicorn app.main:app --host 0.0.0.0 --port 8000 --ssl-keyfile=key.pem --ssl-certfile=cert.pem

For Docker:

# generate TLS cert
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes -subj '/CN=localhost'

# run with cert
docker run -d \
  --device=/dev/ttyUSB0 \
  -v remoteterm-data:/app/data \
  -v $(pwd)/cert.pem:/app/cert.pem:ro \
  -v $(pwd)/key.pem:/app/key.pem:ro \
  -p 8000:8000 \
  jkingsman/remote-terminal-for-meshcore:latest \
  uv run uvicorn app.main:app --host 0.0.0.0 --port 8000 --ssl-keyfile=/app/key.pem --ssl-certfile=/app/cert.pem

Accept the browser warning, or use mkcert for locally-trusted certs.

Systemd Service (Linux)

# Create service user
sudo useradd -r -m -s /bin/false remoteterm

# Install to /opt/remoteterm
sudo mkdir -p /opt/remoteterm
sudo cp -r . /opt/remoteterm/
sudo chown -R remoteterm:remoteterm /opt/remoteterm

# Install dependencies
cd /opt/remoteterm
sudo -u remoteterm uv venv
sudo -u remoteterm uv sync

# Build frontend (optional -- already built in repo and served by backend)
cd /opt/remoteterm/frontend
sudo -u remoteterm npm install
sudo -u remoteterm npm run build

# Install and start service
sudo cp /opt/remoteterm/remoteterm.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now remoteterm

# Check status
sudo systemctl status remoteterm
sudo journalctl -u remoteterm -f

Edit /etc/systemd/system/remoteterm.service to set MESHCORE_SERIAL_PORT if needed.

Testing

Backend:

PYTHONPATH=. uv run pytest tests/ -v

Frontend:

cd frontend
npm run test:run
