Tesla Operating System Support via Local + Relay Connectivity

Important: If you are reading this and want this feature and are willing to be a tester please reach out. Overview Enable Tesla in-car browser control of the Echobox audiophile app by providing a reliable connection mechanism that works across hotspot, home networks, and event environments. This feature should prioritize robust connectivity over zero-config discovery, given known limitations with local networking (mDNS, private IP access) in constrained environments like Tesla’s browser and public Wi-Fi. Problem Users want to control the Echobox app from a Tesla browser by connecting to a local web UI hosted on their Android device. However: mDNS/Bonjour is unreliable across networks (blocked multicast, AP isolation, etc.) Tesla browser may not reliably support .local resolution or private IP access Event/show networks are often hostile to peer-to-peer discovery Relying solely on local discovery leads to inconsistent user experience Goals Provide a consistent and user-friendly connection flow from Tesla browser → Echobox app Support offline/local-first usage where possible Ensure functionality works at: Home networks Phone hotspot Live shows / public Wi-Fi Avoid breaking existing networking features (UPnP, local control) Proposed Solution (Hybrid Approach) 1. Local Control Mode (Primary for Hotspot / LAN) When enabled, the app: Starts a lightweight HTTP server on the device Optionally advertises via mDNS (_echobox._tcp) Displays connection info in-app: Local IP URL (e.g. http://192.168.1.42:port) mDNS URL (e.g. http://echobox.local:port) QR code for quick access Short pairing code Notes: mDNS is treated as a bonus convenience, not required MulticastLock is only acquired while this mode is active Service names include unique instance IDs to avoid conflicts 2. Tesla Mode (Enhanced UX) A dedicated mode optimized for Tesla usage: Automatically: Enables hotspot (if possible) Starts local server Displays a simplified “Connect your Tesla” screen: Large QR code Direct IP URL Optional.local URL 3. Cloud Relay / Remote Access (Fallback) For maximum reliability: App establishes an outbound secure tunnel (WebSocket/WebRTC/HTTPS) Generates a session URL: https://echobox.app/session/{id} Tesla browser connects via public internet Benefits: Works even if: Local network blocks multicast Tesla browser blocks private IPs User is on restrictive Wi-Fi 4. Connection Priority Strategy Client (Tesla browser) attempts: Direct IP (fastest, most reliable locally) mDNS hostname (.local) if supported Cloud relay URL (guaranteed fallback)
