Picture

Some or all PJ-1203A suffer from a bug that causes the energy flow direction to be reported during the next cycle update. In parctice, that means that an incorrect direction is published during update_frequencyfrequency seconds after any transition between producing and consuming.

For each channel x, the option late_energy_flow_x attempts to solve that problem by delaying the publication of power_x, current_x, power_factor_x and energy_flow_x until the next update of energy_flow_x.

The attribute timestamp_x indicates when the power value was actually received from the device. This is typically update_frequency seconds before the publication time when the option late_energy_flow_x is enabled. It should be noted that this delay does not occur when the power value is zero because the energy flow datapoint is neither produced by the device nor needed to compute the sign.

Options

How to use device type specific configuration

late_energy_flow_a: Delay channel A publication until the next energy flow update (default false). The value must be true or false
late_energy_flow_b: Delay channel B publication until the next energy flow update (default false). The value must be true or false
signed_power_a: Report energy flow direction for channel A using signed power (default false). The value must be true or false
signed_power_b: Report energy flow direction for channel B using signed power (default false). The value must be true or false
ac_frequency_calibration: Calibrates the ac_frequency value (absolute offset), takes into effect on next report of device. The value must be a number.
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
