Post subject: | updated dashboard calculating energy use incorrectly |
seems that the new dashboard has some very dubious calculations this one is plainly wrong .... cc151211.png [ 98.22 KiB | Viewed 35289 times ] its only runs for about 8 hours and it only gets above 1kW for a brief spike yet it reckons 8.59 kWh - I dont think so, I downloaded the data in question from pachube and that give a much more reasonable 2.31 kWH. Since the energy converted in a power vs time graph is the area under the line its quite easy to calculate - in the case of the pachube data summing all the (power*interval readings) and dividing the result by 3,600,000 directly give an approximation in kWh. and again today cc dashboard reading 8.38kWh(looks wrong 16 hours at less than 400 w with about 5 spikes above) readings summed from pachube 5.2kWh |
