I see a lot of people using a smart switch to turn of their equipment (printer, PC, TV).
I just makes me wonder, what uses more energy, the smart-switch or the standby mode of the unit being switched off 
I looked up the specs for my printer, it should consume around 3 watt in standby mode, while my (wifi) smart switches should use approx 2 watt 
Has anyone ever measured the difference??
Do they actually save anything??
Or is it potato patato?
