i have the sum off my overal usage which adds all the time. now i try to get the values off my energy usage during night time… and from there the average.
i tried the following and it looks not to bad, but i need the values (so every day one value how much i was using in this time) - (aka it would be the difference from 7pm value to 7am value (next day) and so on
actualy i need one value: average usage over last x days between 7pm till 7am
thanks for any help
my work till now… no clue if this is correct
