I only see a significant discrepancy between my smart plug and Axeos power monitor. The smart plug (which I know is accurate) reports that the miner is drawing 27 W at the wall, while the dashboard only shows 22.5 W. I guess this difference is due to PSU efficiency, with the extra power likely dissipated as heat.

Would it be useful to have an estimated real power draw on the dashboard?
Something like:
Power 22.5 W (-10/15% (editable) PSU efficiency: 4.5 W = 27 W)
assuming one is using the stock power supply?

The only thing measured is the power from the voltage regulator to the ASIC's.
What is not measured:
The power to the ESP32 (minimum)
The efficiency of the VR (input is more than the output)
Power to the Fan (original fan has label of 12V 0.12amp = 1.44 watt)
and like you mentioned: the efficiency of the PSU (AC -> DC)

An offset of 6W has already been taken into account in the power measurement: https://github.com/un-painted-org/ESP-Miner/blob/LV07/main/power/power.c#L13

However, this offset is unfortunately not constant and also depends on the power supply unit used.

For the original power supply I get a good match with the default settings of voltage / frequency.
