Handle Long entity names due to long DeviceInfo names

solves #113

---

PR Type

Bug fix, Enhancement

---

Description

• Introduced IecEntityType enum to differentiate between GENERIC, CONTRACT, and METER entity types.
• Refactored get_device_info function to utilize the new IecEntityType, improving how device information is constructed.
• Enhanced binary sensor and sensor entities to initialize with specific entity types, improving data handling and accuracy.
• Updated translation keys in en.json to make the UI text more concise and user-friendly.

PR Review 🔍

⏱️ Estimated effort to review [1-5]	3, because the PR involves multiple files with significant changes including refactoring and introduction of new enums and methods. The logic changes are moderate, and understanding the context of entity types and their handling in device information requires careful review.
🧪 Relevant tests	No
⚡ Possible issues	Possible Bug: The use of iec_entity_type in get_device_info assumes that meter_id is provided when the entity type is METER. If meter_id is None, this could lead to incorrect or incomplete device information.
	Data Handling: The refactoring introduces new entity descriptions and modifies how device information is constructed. There is a potential for data mismatches or errors if not all scenarios are handled correctly, especially with the new enum types.
🔒 Security concerns	No

PR Code Suggestions ✨

Category	Suggestions
Maintainability	Improve variable naming for clarity and to avoid potential conflicts with built-in names. Consider using a more descriptive variable name for name in the get_device_info function to avoid confusion with the built-in Python function name() and to enhance code readability. custom_components/iec/commons.py [54] -name = "IEC" +device_name = "IEC"
	Refactor get_device_info into smaller functions for better maintainability and readability. To improve the maintainability and readability of the get_device_info function, consider refactoring the large function into smaller, more focused functions. This can help in isolating functionality and making the code easier to manage and test. custom_components/iec/commons.py [40-77] def get_device_info(contract_id: str, meter_id: str | None, iec_entity_type: IecEntityType = IecEntityType.GENERIC) -> DeviceInfo: """Get device information based on contract ID and optional meter ID. ... + return create_device_info(identifier, name, model, serial_number) + +def create_device_info(identifier, name, model, serial_number): return DeviceInfo( identifiers={(DOMAIN, identifier)}, name=name, manufacturer="Israel Electric Company", model=model, serial_number=serial_number, )
Best practice	Ensure consistent data type handling for contract_id by converting it at the function start. To ensure that the contract_id is always a string and to avoid repeated conversions, convert contract_id to a string at the beginning of the get_device_info function. custom_components/iec/commons.py [59] +contract_id = str(contract_id) contract_id = str(int(contract_id))
Performance	Simplify and enhance the performance of entity type handling using a dictionary mapping. Instead of using a match-case statement, consider using a dictionary mapping for iec_entity_type to functions or lambda expressions that return the required values. This approach can simplify the code and improve performance. custom_components/iec/commons.py [58-66] -match iec_entity_type: - case IecEntityType.CONTRACT: - contract_id = str(int(contract_id)) - name = f"IEC Contract [{contract_id}]" - model = "Contract: " + contract_id - case IecEntityType.METER: - name = f"IEC Meter [{meter_id}]" - model = "Contract: " + contract_id - serial_number = ("Meter ID: " + meter_id) if meter_id else "" +entity_type_mapping = { + IecEntityType.CONTRACT: lambda: (f"IEC Contract [{contract_id}]", "Contract: " + contract_id, None), + IecEntityType.METER: lambda: (f"IEC Meter [{meter_id}]", "Contract: " + contract_id, ("Meter ID: " + meter_id) if meter_id else "") +} +name, model, serial_number = entity_type_mapping.get(iec_entity_type, lambda: ("IEC", None, None))()
Possible issue	Add validation for meter_id to prevent runtime errors when it is required. To avoid potential runtime errors, add a validation check for meter_id when the iec_entity_type is METER to ensure it is not None before using it in string operations. custom_components/iec/commons.py [65] +if iec_entity_type == IecEntityType.METER and meter_id is None: + raise ValueError("meter_id is required when iec_entity_type is METER") serial_number = ("Meter ID: " + meter_id) if meter_id else ""
