While I was reading some articles regarding home automation, I found this recent blogpost:
http://goughlui.com/2015/12/23/standbyno-load-power-consumption-are-we-doing-it-right/The main point of the post is: how much can we rely on (cheap) energy meters to correctly measure stand-by power, when the load has a relatively high power factor (as with many switching PSUs)?
As Martin often delves into the energy measurement field, I thought it could be an interesting topic for some future videos.
