styrened 0.14.0

Unified Styrene library and headless daemon for RNS/LXMF mesh networking

styrened

Daemon, library, and TUI for Reticulum mesh networks.

Overview

styrened is the core of the Styrene mesh networking stack. It provides a headless daemon for edge devices, a terminal UI for interactive fleet management, and a Python library for building mesh applications on RNS/LXMF.

Key Features:

• Mesh daemon — headless operation on edge devices (Raspberry Pi, NixOS, containers)
• Terminal UI — full-featured TUI for fleet management, chat, device provisioning
• RPC over LXMF — remote device management (status, exec, reboot, config)
• Device discovery — automatic mesh topology tracking
• Auto-reply — automated message responses with cooldown
• Direct links — point-to-point RNS links for status queries and speedtests
• Mesh VPN — WireGuard tunnels bootstrapped over LXMF (IPv6 ULA addressing)
• HTTP API (optional) — REST/WebSocket endpoints for external integration
• Nix flake — declarative NixOS deployment with OCI container builds

Installation

# Full stack: daemon + TUI (via meta-package)
pip install styrene

# Daemon only (minimal dependencies)
pip install styrened

# Daemon + TUI
pip install styrened[tui]

# All extras
pip install styrened[tui,web,metrics,yubikey]

Nix Flake

nix run github:styrene-lab/styrened

Container

docker pull ghcr.io/styrene-lab/styrened:latest

Usage

# Run daemon
styrened daemon

# Run TUI
styrene

# CLI tools
styrened devices              # List discovered mesh devices
styrened devices -w 10        # Wait 10s for announces
styrened status               # Local daemon health
styrened status <dest>        # Query remote node
styrened send <dest> "hello"  # Send message
styrened exec <dest> uptime   # Remote command execution
styrened doctor               # Installation diagnostics
styrened doctor --setup       # Interactive setup wizard
styrened identity             # Show local identity

Async-first — all network operations use asyncio. The daemon runs an event loop with periodic tasks for announces, discovery, and mesh maintenance.

Protocol discrimination — LXMF messages are routed to handlers based on fields["protocol"], supporting chat (NomadNet/MeshChat), Styrene wire protocol, and VPN handshake messages.
