custom_components/sat/manufacturer.py (4)
28-31: Add a docstring to clarify the identifier’s purpose.While the abstract property is adequate, a short docstring explaining what the identifier represents would help future maintainers.
43-43: Consider logging unknown manufacturer names.Returning
Noneis fine, but logging a warning or error would make it easier to debug issues if a wrong manufacturer name is provided.def resolve_by_name(name: str) -> Optional[Manufacturer]: + import logging + logger = logging.getLogger(__name__) if not (module := MANUFACTURERS.get(name)): + logger.warning(f"Unknown manufacturer name requested: {name}") return None return ManufacturerFactory._import_class(module, name)()
46-46: Add error handling for module/class import.A try/except block would improve resilience if the module or class doesn’t exist. This can reduce cryptic import tracebacks and highlight configuration issues clearly.
def resolve_by_name(name: str) -> Optional[Manufacturer]: if not (module := MANUFACTURERS.get(name)): return None - return ManufacturerFactory._import_class(module, name)() + try: + manufacturer_class = ManufacturerFactory._import_class(module, name) + return manufacturer_class() + except (ImportError, AttributeError) as e: + import logging + logger = logging.getLogger(__name__) + logger.error(f"Failed to load manufacturer '{name}' from module '{module}': {e}") + return None
60-60: Wrap dynamic import in a try/except block.A little extra caution can prevent unhandled exceptions if a module or class no longer exists or was renamed.
@staticmethod def _import_class(module_name: str, class_name: str): - return getattr(__import__(f"custom_components.sat.manufacturers.{module_name}", fromlist=[class_name]), class_name) + try: + mod = __import__(f"custom_components.sat.manufacturers.{module_name}", fromlist=[class_name]) + return getattr(mod, class_name) + except (ImportError, AttributeError) as e: + import logging + logger = logging.getLogger(__name__) + logger.error(f"Could not import '{class_name}' from module '{module_name}': {e}") + raisecustom_components/sat/manufacturers/other.py (1)
5-8: Consider documenting the special identifier valueThe
-1identifier is appropriate for a catch-all "Other" manufacturer, but it would be helpful to document why this special value was chosen.@property def identifier(self) -> int: + # Using -1 as a special identifier for the catch-all "Other" manufacturer return -1custom_components/sat/manufacturers/nefit.py (1)
5-8: Consider improving identifier managementThe current implementation uses magic numbers for manufacturer identifiers. Consider these improvements:
- Create an enum or constants file to centrally define all manufacturer identifiers
- Document the significance of these specific values
- Add validation to ensure uniqueness at runtime
Example implementation:
# custom_components/sat/const.py from enum import IntEnum, unique @unique class ManufacturerID(IntEnum): """Unique identifiers for each manufacturer.""" OTHER = -1 IDEAL = 6 SIME = 27 # Note: Currently conflicts with Immergas NEFIT = 131 # ... add other manufacturersThis approach would:
- Ensure uniqueness through the
@uniquedecorator- Make it easier to track and maintain identifiers
- Provide better IDE support and type safety
custom_components/sat/manufacturers/radiant.py (1)
5-8: LGTM! Consider adding documentationClean implementation with a unique identifier value. Consider adding a docstring to document the purpose of the identifier property and its usage.
@property def identifier(self) -> int: + """Return the unique manufacturer identifier. + + This identifier is used to uniquely identify the manufacturer across the system. + The value 41 is reserved for Radiant manufacturer. + """ return 41custom_components/sat/manufacturers/immergas.py (1)
5-8: Add documentation for the identifier value.While the implementation is correct, consider adding a docstring to explain the significance of the identifier value
27and its source/standard if applicable.@property def identifier(self) -> int: + """Return the manufacturer's unique identifier. + + Returns: + int: The unique identifier (27) for Immergas. + """ return 27custom_components/sat/manufacturers/vaillant.py (1)
5-8: Add documentation for the identifier value.Consider adding a docstring to explain the significance of the identifier value
24and its source/standard if applicable.@property def identifier(self) -> int: + """Return the manufacturer's unique identifier. + + Returns: + int: The unique identifier (24) for Vaillant. + """ return 24custom_components/sat/manufacturers/viessmann.py (2)
5-8: Add documentation for the identifier value.Consider adding a docstring to explain the significance of the identifier value
33and its source/standard if applicable.@property def identifier(self) -> int: + """Return the manufacturer's unique identifier. + + Returns: + int: The unique identifier (33) for Viessmann. + """ return 33

1-1: Consider enhancing identifier management.To improve maintainability and prevent potential issues:
- Document the identifier scheme in a central location (e.g., in the base
Manufacturerclass)- Consider using an Enum or constants for manufacturer identifiers
- Add runtime validation to ensure identifier uniqueness across all manufacturer implementations
Example implementation:
# custom_components/sat/manufacturer.py from enum import IntEnum class ManufacturerID(IntEnum): VAILLANT = 24 IMMERGAS = 27 VIESSMANN = 33 INTERGAS = 173 # ... other manufacturers class Manufacturer: @property @abstractmethod def identifier(self) -> int: """Return the manufacturer's unique identifier. These identifiers are standardized values used to identify different manufacturers in the SAT protocol. Returns: int: A unique identifier from ManufacturerID enum """ pass

6-23: Dictionary mapping appears solid.The simplified dictionary is much cleaner than a nested structure and straightforward to maintain. Ensure that all entries align with the corresponding classes and that any class naming/case matches the dictionary keys to avoid import errors.
52-54: Instantiation for every entry is acceptable given a small dictionary size.This list comprehension instantiates each manufacturer class to compare identifiers. Since the dictionary is small, performance impact is negligible. If the list grows significantly, consider caching or indexing by identifier.

5-7: Ensure the identifier matches ATAG’s actual member ID.Returning 4 fulfills the new contract. Confirm that this value doesn’t collide with another manufacturer’s identifier unless that is intentional.
custom_components/sat/manufacturers/baxi.py (1)
5-7: Verify that using the same identifier as ATAG is intended.With both ATAG and Baxi returning 4, it’s unclear if this allows proper disambiguation by ID in
resolve_by_member_id(). If each brand truly needs a unique ID, consider updating one of them.custom_components/sat/manufacturers/ideal.py (1)
