Been interested in how much electricity I'm using so got one of these Ecowatt devices. It plugs in the wall and you just plug in your electricity into the front socket. No buttons or settings involved.
The display changes every few seconds and shows how much CO2 is being let off together with cost per hour and how much has been used up until now.
The desk area in the previous 2 pics uses up 4 yen per hour.The air conditioner which acts as our heating device uses about 50 yen per hour. Vacuuming for a few mins uses up 1 yen. Still need to measure how much the server rack uses up.
Our monthly electricity bill of late costs about 15,000 yen but costs much less in Spring or Autumn when we don't need the heating or cooling devices. Are you aware or how much is being paid for electricity in your household?
Folks interested in this device can get it at Amazon for 2,980 yen.
