When fitted with meters*, Melcloud reports watt-hours for the past minute. Multiply by 60 to get current power in watts.
*CanMeasureEnergyConsumed value will be true.
When there’s no meter, input power can be estimated using HeatPumpFrequency, which is compressor percentage Hz. Divide by 100 and multiply by the maximum electric input for that model in watts. I.e. 3,270 for 8.5 kW model, 3,730 for the 11.2 kW model. I also add in the pumps to give something a little more realistic, but it’s very crude. Oh, plus 20W for standby.
This formula has been superceded by a more accurate one described in post #19
