Smart Home App with Matter Gateway API Integration

# Technical Specification — Matter Plugin for Larnitech Integration ## Project Title Matter Plugin for Larnitech Smart Home System ## Project Description We need a developer to create a Matter integration plugin for the Larnitech smart home platform. The plugin must integrate with the existing Larnitech application and communicate through the official Larnitech API: [login to view URL] The goal of the project is: 1. Expose Larnitech devices to the Matter ecosystem, allowing them to be controlled from Matter-compatible controllers such as: * Apple Home * Google Home * Amazon Alexa * Home Assistant * Other Matter-compatible apps 2. Allow Matter devices to be imported/added into the Larnitech ecosystem and controlled from the Larnitech application. The solution should act as a bridge between Larnitech and Matter networks. The plugin will run on a Raspberry Pi Compute Module device with Linux Ubuntu installed, therefore the solution should be optimized for stable long-term operation on ARM-based Linux hardware. --- # Main Features ## Larnitech → Matter Expose existing Larnitech devices as Matter devices. Supported device types should include: * On/Off Lights * Dimmers * RGB/RGBW Lights * Thermostats * Air Conditioners * Temperature Sensors * Humidity Sensors * Motion Sensors * Leak Sensors * Switches and relays * etc... The plugin should: * Synchronize device states * Support attribute updates in real time * Handle Matter commissioning and pairing * Support multiple endpoints/devices simultaneously --- ## Matter → Larnitech Allow commissioning and importing Matter devices into Larnitech. Features: * Discover Matter devices on the network * Pair and commission Matter devices * Create corresponding devices/entities in Larnitech * Synchronize state and commands between Matter and Larnitech --- # Technical Requirements ## Platform Requirements The solution must run on: * Raspberry Pi Compute Module * Ubuntu Linux (ARM architecture) The plugin should: * Work reliably as a background service/daemon * Automatically restart after reboot * Support easy deployment and updates * Have low resource consumption suitable for embedded hardware Docker support is a plus. --- ## API Integration Use the official Larnitech API: [login to view URL] The plugin must: * Authenticate and communicate with Larnitech controllers * Read/write device states * Subscribe to updates/events if supported * Synchronize device metadata and capabilities --- ## Matter Support Use official Matter SDK or compatible libraries: * connectedhomeip (CHIP SDK) * Python bindings or C++ implementation Required: * Matter advertisement * Commissioning support * Standard Matter clusters * Multi-device support * Persistent pairing/fabric storage --- # Architecture Requirements The solution should include: * Modular architecture * Device mapping layer (Larnitech ↔ Matter) * State synchronization engine * Logging and debugging tools * Configuration management Optional: * REST API * Web UI for monitoring and configuration * Docker deployment --- # Preferred Technologies Preferred: * Python Possible alternative: * C++ Suggested stack: * Python 3.11+ * FastAPI * Matter SDK / CHIP * AsyncIO * SQLite or lightweight persistence --- # Persistence Requirements The system must persist: * Device mappings * Matter fabrics/pairings * Device states * Configuration data Data should be restored automatically after restart. --- # Deliverables The developer should provide: * Full source code * Git repository or ZIP archive * README with setup instructions * API documentation * Example configuration * Test scripts * Deployment instructions for Raspberry Pi / Ubuntu License: * MIT or other permissive open-source license --- # Acceptance Criteria The project will be considered complete when: * Larnitech devices can be controlled from Matter controllers * Matter devices can be added into Larnitech * State synchronization works correctly in both directions * Pairing and commissioning are stable * Multiple devices are supported simultaneously * Persistence works after restart * The plugin runs stably on Raspberry Pi Compute Module with Ubuntu * Code is modular and documented --- # Suggested Milestones ## Milestone 1 * Base Matter bridge setup * Connection to Larnitech API * Simple On/Off device support ## Milestone 2 * Lighting devices (dimmer/RGB) * Thermostat and sensors * State synchronization ## Milestone 3 * Matter device import into Larnitech * Advanced device support * Persistence and stability improvements ## Milestone 4 * Documentation * Testing with Apple Home / Google Home / Alexa * Final delivery --- # Freelancer Proposal Should Include * Preferred language (Python/C++) * Selected Matter SDK/libraries * Estimated timeline * Relevant Matter / IoT integration experience * Experience with Raspberry Pi / Linux embedded systems * Similar smart-home or gateway projects
