RS-485 Heat Pump Tools

Reverse-engineering and control tools for an Elfim heat pump connected through an Elfin serial-to-network gateway.

The directory contains:

• an Android application that polls and writes heat-pump registers over Modbus RTU-over-TCP,
• Python capture, clustering, CRC, and passive-learning utilities,
• a C++ TCP/WebSocket proxy used during protocol exploration.

Live captures, local SDK state, build products, and third-party hardware manuals are excluded from Git.
