Octoprint plugin - power usage

Hi, I use octoprint with my printer, and I just installed a few plugins including one that gives printer stats. It is asking for the power consumption of several components including (with the default values):

I don't suppose someone else has already found these values by chance? I've been looking for the wattage of the heatbed and the hotend but so far not having much success.

I think you will find that the values will vary according to the printer and the setting of the 12V rail.

Nominally, the heated bed will be around 120W and the extruder 30W, but you would have to measure the resistance of those parts (when hot), the voltage they are being supplied with and then do the math.

Thanks Peter. It's not really worth doing any real work, I'm just playing around. I'll just take the values that you provided and the remaining defaults and call it "close enough". haha

Values from Octoprint will always be a guess, just as with the print time estimate.

Better to use a power usage meter if you want more precise figures.
