Electricity price comparison function
---------------
There are contracts where the electricity rate changes depending on the time of day when electricity is used a lot (daytime on weekdays, nighttime, holidays, etc.).
You can compare multiple contracts based on what happens when you change to such a contract.

If you record logs for a long period of time, the tendency of usage that suits you will become clearer.
Let's start by recording and accumulating logs.
