• Supports serial, network, and BLE (now too!) connections for Meshtastic devices
• Custom fields are embedded in Matrix messages for relaying messages between multiple 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 an MQTT broker, if configured in the Meshtastic firmware
• ✨️ Bidirectional replies and reactions support ✨️
