M<>M Relay

(Meshtastic <=> Matrix Relay)

A powerful and easy-to-use relay between Meshtastic devices and Matrix chat rooms, allowing seamless communication across platforms. This opens the door for bridging Meshtastic devices to many other platforms.

Features

• Bidirectional message relay between Meshtastic devices and Matrix chat rooms, capable of supporting multiple meshnets
• Supports serial, network, and BLE (now too!) connections for Meshtastic devices
• Custom keys are embedded in Matrix messages which are used when relaying messages between two or more meshnets.
• Truncates long messages to fit within Meshtastic's payload size
• SQLite database to store node information for improved functionality
• Customizable logging level for easy debugging
• Configurable through a simple YAML file
• Supports mapping multiple rooms and channels 1:1
• Relays messages to/from a MQTT broker, if configured in the Meshtastic firmware (Note: Messages relayed via MQTT currently share the relay's meshnet_name)

We would love to support Matrix E2EE rooms, but this is currently not implemented. If you are familiar with matrix-nio, we would gladly accept a PR for this feature!
