Options

How to use device type specific configuration

  • ac_frequency_calibration: Calibrates the ac_frequency value (absolute offset), takes into effect on next report of device. The value must be a number.

  • ac_frequency_precision: Number of digits after decimal point for ac_frequency, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3

  • voltage_calibration: Calibrates the voltage value (percentual offset), takes into effect on next report of device. The value must be a number.

  • voltage_precision: Number of digits after decimal point for voltage, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3

  • power_calibration: Calibrates the power value (percentual offset), takes into effect on next report of device. The value must be a number.

  • power_precision: Number of digits after decimal point for power, takes into effect on next report of device. This option can only decrease the precision, not increase it. The value must be a number with a minimum value of 0 and with a with a maximum value of 3
