sma-proto

A Rust crate that provides an implementation of the SMA Speedwire protocol for building custom applications that communicate with SMA energy-meters or inverters.

Crate Features and Goals

• High level client for easy integration into applications.
• Implement energy-meter protocol.
• Implement inverter data readout protocol.
• Optional no_std support for embedded devices.
• Verify messages during de-serialization.
• Being efficient if possible.
• Simple Wireshark dissector for debugging on network layer. (Lua script is located in the repository root.)

Rust Feature Flags

• std (default) — Remove this feature to make the library no_std compatible.
• client — Enables a tokio based high level client.
• heapless - Enables support for heapless vectors.

Specification

• Energymeter protocol: link
• Inverter protocol: reverse-engineered
