That little freezer is using near max power right now.
In the cold weather, it uses a lot less. (My guess is <=$30 a year).
One thing that I would like to do, is move the decimal point on the rate.
Instead of 16.61, I would like to have 0.1661
Have not figured that out yet. If it's even possible.
I recommend doing a couple of resets before setting the rate and first use.
Might save you from any frozen Watts display..
Having $ displayed is not really a big deal, as long as the kWh number is accurate.
I think that doing a reset is going to be common, since I'll want to restart
measurements on a new load once in a while. The reset zeros the time, days & kWh..
