custom_components/sat/helpers.py (1)

27-39: Simplify integer conversion

While the change to return int is good, the implementation can be simplified.

-    return round((date_time.hour * 3600) + (date_time.minute * 60) + date_time.second, 0)
+    return int((date_time.hour * 3600) + (date_time.minute * 60) + date_time.second)

The current round(x, 0) returns a float that's implicitly converted to int. Using int() directly is more explicit and achieves the same result.

custom_components/sat/mqtt/__init__.py (1)

25-28: LGTM! Consider using more specific type for self.data

The type annotations are appropriate and improve code clarity. However, consider using a more specific type for self.data such as dict[str, Any] to better document the expected structure.

-        self.data: dict = {}
+        self.data: dict[str, Any] = {}

🔇 Additional comments (18)
custom_components/sat/relative_modulation.py (1)

21-23: Type annotations look good!

The added type annotations correctly reflect the usage of these instance variables throughout the class.

custom_components/sat/mqtt/ems.py (1)

103-105: LGTM! Return type now matches parent class contract

The return type change from SatMqttCoordinator to None correctly aligns with the abstract method definition in the parent class. The pass statement is appropriate as no initialization is needed yet.

custom_components/sat/overshoot_protection.py (1)

20-23: LGTM! Type annotations enhance code clarity

The type annotations are well-chosen and accurately reflect the usage of these variables throughout the class:

  • float for _alpha used in exponential moving average
  • float | None for _stable_temperature reflecting its optional nature
  • SatDataUpdateCoordinator for _coordinator matching the constructor parameter
  • int for _setpoint matching values from OVERSHOOT_PROTECTION_SETPOINT
custom_components/sat/area.py (4)

8-8: LGTM! Imports align with type annotations

The new imports for HeatingCurve, PID, and PWM support the type annotations added to the class.

Also applies to: 10-11


23-29: LGTM! Type annotations enhance code clarity

The type annotations in the Area class are well-chosen and improve code clarity:

  • str for _entity_id
  • HomeAssistant | None for _hass reflecting its optional nature
  • Specific controller types for pid, heating_curve, and pwm

81-85: Improved error handling logic

The new error handling approach is more robust, checking both self.error and self.heating_curve.value before proceeding with the PID update. This prevents potential issues with undefined values.


89-94: LGTM! Type annotations improve type safety

The type annotations in the Areas class constructor and instance variables are well-defined:

  • list[str] for entity IDs
  • MappingProxyType[str, Any] for configuration data
  • list[Area] for areas collection
custom_components/sat/mqtt/opentherm.py (1)

89-89: Verify the parent class's implementation.

The return type has been changed from float | None to float. This change implies that the parent class's implementation of maximum_hot_water_setpoint must also return a float value. Please ensure that the parent class's implementation never returns None.

Run the following script to verify the parent class's implementation:

custom_components/sat/esphome/__init__.py (2)

52-58: LGTM! Type annotations improve code clarity.

The added type annotations for instance variables enhance code clarity and maintainability by explicitly defining the expected types.


118-118: Verify the parent class's implementation.

The return type has been changed from float | None to float. This change implies that the parent class's implementation of maximum_hot_water_setpoint must also return a float value. Please ensure that the parent class's implementation never returns None.

Run the following script to verify the parent class's implementation:

✅ Verification successful

Return type change is safe

The parent class SatDataUpdateCoordinator in coordinator.py always returns a float value of 60. All derived implementations, including the current one, fall back to this base implementation when their specific data source doesn't provide a value, ensuring a float is always returned.

🏁 Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify the parent class's implementation of maximum_hot_water_setpoint.

# Test: Search for the parent class's implementation.
ast-grep --pattern $'class SatDataUpdateCoordinator {
  $$$
  maximum_hot_water_setpoint($$$) {
    $$$
  }
  $$$
}'

Length of output: 117


Script:

#!/bin/bash
# First, let's look at the imports in the current file to identify the parent class
echo "=== Imports in __init__.py ==="
rg "^from|^import" custom_components/sat/esphome/__init__.py

# Then, let's search for any class with maximum_hot_water_setpoint method
echo -e "\n=== Classes with maximum_hot_water_setpoint method ==="
ast-grep --pattern 'maximum_hot_water_setpoint($$$) {
  $$$
}'

# Finally, let's search for any occurrence of maximum_hot_water_setpoint
echo -e "\n=== All occurrences of maximum_hot_water_setpoint ==="
rg "maximum_hot_water_setpoint" -A 2

Length of output: 3360

custom_components/sat/pwm.py (2)

14-14: LGTM! Clear docstring for PWMState enum.

The added docstring clearly describes the purpose of the PWMState enum.


Line range hint 25-77: LGTM! Comprehensive type annotations.

The added type annotations for instance variables are accurate and comprehensive, improving code clarity and maintainability.

custom_components/sat/pid.py (1)

46-77: LGTM! Comprehensive type annotations.

The added type annotations for instance variables in both __init__ and reset methods are accurate and comprehensive, improving code clarity and maintainability.

custom_components/sat/coordinator.py (1)

357-357: LGTM! Improved type safety with Optional type hint.

The change correctly uses Optional[SatClimate] to indicate that the climate parameter can be None, which aligns with the default value and improves type safety.

custom_components/sat/config_flow.py (2)

4-4: LGTM! Added required import for type hints.

The addition of Optional from typing is necessary for the type hints used in the file.


522-522: LGTM! Improved type safety with Optional type hints.

The change correctly uses Optional[str] to indicate that both default_topic and default_device parameters can be None, which aligns with their default values and improves type safety.

custom_components/sat/climate.py (2)

8-8: LGTM! Added required import for type hints.

The addition of Optional from typing is necessary for the type hints used in the file.


72-72: LGTM! Improved type safety with Optional type hints.

The change correctly uses Optional[float] and Optional[int] to indicate that both boiler_temperature and started parameters can be None, which aligns with their default values and improves type safety.
