- **line_frequency** (*Optional*, string): The nominal AC line frequency of the supply voltage. One of ``50Hz``, ``60Hz``. Defaults to ``50Hz``.
- **address** (*Optional*, int): The address of the BL0942 from its strapping pins. Defaults to ``0``.
- **reset** (*Optional*, boolean): Whether to reset the BL0942 chip on startup, resetting all internal counters. Defaults to ``true``.
- **current_reference** (*Optional*, float): The calibration parameter for current readings. Defaults to ``251213.46469622``.
- **voltage_reference** (*Optional*, float): The calibration parameter for voltage readings. Defaults to ``15873.35944299``.
- **power_reference** (*Optional*, float): The calibration parameter for power readings. Defaults to ``596.0`` unless either ``current_reference`` or ``voltage_reference`` are explicitly set, in which case it is calculated. See :ref:`bl0942-calibration` for more details.
