MOSH is a modular smart-home and embedded networking platform built around flexible nodes, reusable elements, and transport-independent communication.

It is designed to let small devices, bridge nodes, and higher-capability controllers participate in one system while keeping routing, messaging, and application behavior clearly separated.

  • Curious about why all this was developed?
• Getting Started
  • New to MOSH? Start here for the high-level architecture and first steps.
• MOSH Overview
  • Learn how MOSH models nodes, elements, and system behavior.
• MTRP Protocol
  • Read the routing and transport protocol reference.
• IMC Layer
  • Learn how MOSH bridges application behavior to carriers and protocols.

MOSH is organized in layers:

• MOSH defines smart-home and node behavior
• IMC provides the message and carrier abstraction between layers
• MTRP provides routing and multi-transport packet delivery
• Hardware/Transports provide the physical communication paths

This separation allows the system to grow without tightly coupling application logic to any single radio, board, or transport.

MOSH is under active development.

Some older pages may describe behavior or architecture that has since changed. When in doubt, prefer:

• Architecture Map
• Current MOSH Architecture
• Current MTRP Reference

• Legacy or outdated documentation may be retained for reference during development.
• Protocol and architecture pages are being updated gradually toward the current design.
