Async implementation of SunSpec Modbus communication.
Project description
async-sunspec is an asynchronous Modbus communication library for Python focused on SunSpec-compliant devices. It provides tools to create both SunSpec clients and servers, with a runtime model system for representing SunSpec data structures and a modular architecture.
It is an async-first library built on top of pymodbus, meant to handle multiple devices concurrently without blocking. The client supports scanning for SunSpec devices and reading their models asynchronously.
Features
Usage overview
Configure a server (device): assemble model instances, bind them to a SunSpecDevice and run the Modbus server.
Configure a client (master): create a SunSpecClient, connect to a device, scan for models and interact with them asynchronously.
Advantages
- Scalable concurrency: asyncio-based I/O lets a single process manage many
connections efficiently.
Requirements
Python >=3.12
pymodbus==3.12.1
