Building a Custom Modbus Cache to Fix Huawei SUN2000 Connection Limits

This project highlights a crucial bottleneck in smart home architectures where single-connection hardware like the Huawei SUN2000 restricts data flow across multiple clients. By replacing a traditional proxy with a custom asyncio-based cache server, it eliminates transaction collisions and ensures reliable data distribution. It serves as a practical blueprint for developers tackling concurrent hardware limitations in local IoT ecosystems.
