❓COP - how to handle?

[Schmidtjanroman]

As I'm diggin deeper into my statistics I came up with a question regarding COP of heating and warm water and how to handle it.

• the entity says per day, so my per day COP is the last at 23:59:59 o'clock? Maybe a few seconds early becaus of the update intervalls of the integration.
• when building a avg for month or year, what should I actually use for it. The COP AVG or a the named above value per day on a certain time?

This is just a basic bar chart with min, max and avg per day, without any logic behind it.

The most accurate value you get is the one closest to midnight, as it contains data for a whole day.
IMO it should be good enough to calculate the daily average and use that one to calculate the monthly / yearly average

is there a possibility in home assistant to create a rolling sensor (last 24h)?
