High Energy usage

brooklyn07

The one I have monitors the usage every 10 minutes so I just added it up overnight - it looks like this. Or have I got it wrong?

No, that makes perfect sense, although it would have caused less confusion if you'd reported it as 300Wh not 300w.

How long was "overnight" exactly? Eight hours?

Yes it was from midnight to 8am

What happened between 7am and 9am? Something stopped using electricity big time

Given that this is an energy monitor plot from the fridge / freezer, I suspect that the compressor cycled off at 7am and didn't turn on again until 9am.

Looks like it draws about 110W when running and 7W all the time for the electronics and the display.  That would be entirely normal.  (110W power consumption continuously for one sixth of an hour uses 18.33Wh of energy.)

Always very important to understand the difference between power and energy and not to mix up the units.  It may sound pedantic but you can go seriously astray if the two are confused.

Brooklyn 07 - did you ever find out what was hogging power at night? 

I had a smart meter installed 14 June 22, and I have just done some analysis on my very high power consumption below. My baseload is 45p/hour and my total consumption is 71p/hour.  45p is all the the things on at night when you have gone to bed 26p an hour for doing things. How do I get the baseload down? I did an exercise last night of turning everything off including standalone freezer but just leaving 2x fridge freezers on and the consumption was still 24p per hour. Are 2x fridge freezers  really churning through 0.7kWh every hour? We turned off underfloor heating, wifi, wifi extenders, outdoor freezer, unplugged 2 TVs, unplugged all computers, 2x immersion heaters, set top boxes etc etc.  Anyone any other ideas for stopping power hogs.

I would suggest starting your own thread, and please work in kWh, not cost per hour as it makes it a lot harder to work with your data...
