get_scale

get_scale(address: str, min_threshold: float, max_threshold: float, enabled: bool, calibration_key: str = 'SCALE_CALIBRATION_VALUE', weight_to_calibrate_key: str = 'SCALE_WEIGHT_TO_CALIBRATE') → Scale | NullScale[source]

Factory function to initialize the Scale.

Parameters:

  • address (str) – The I2C address of the scale.

  • min_threshold (float) – The minimum weight threshold for valid measurements.

  • max_threshold (float) – The maximum weight threshold for valid measurements.

  • enabled (bool) – Whether this scale is physically present and should be initialized at all.

  • calibration_key (str) – The setting key holding this scale’s calibration factor.

  • weight_to_calibrate_key (str) – The setting key holding the known weight last used to calibrate this scale.

Returns:

An initialized Scale instance or a null scale if disabled or on failure.

Return type:

Scale | NullScale
