The full story
The contribution extends the existing Modbus TCP integration rather than adding a separate ecoMain-specific reader. It adds configurable word order, register grouping and address conventions while updating compatibility with different pymodbus versions.
The author describes tests against a local Modbus server and compatibility comparisons with an existing Fronius example. Real ecoMain hardware had not been tested.
