This is why I don't have a "smart" fridge...
Being single living alone this would work for me...
All the extra space in my fridge is filled with 1/2 gallon plastic milk jugs full of water to lessen the energy impact of opening and closing the door. Kinda afraid to put the watt meter on it to see if it is actually saving anything. The internet says it doesn't save because of the energy required to chill the water in the first place. Maybe should have started the project in winter and put the jugs outside overnight to chill/freeze.
Might turn out like my timer switch idea. My porch light is dusk to dawn. Thought about putting a timer on it so it only works dusk to mid-nite. But with only a 9 watt LED bulb it would take over 2 years of operation for a timer to pay for itself with what it would save.
