Hourly data

[AlexWhitehouse]

Is it possible to expose a sesnsor which records the usage for the half hourly data? So that you can see a graph over time of the data every 30mins of usage/cost?

I propose doing something along the lines of: query hour by hour and return the values for each hour. If the returned value is 0, it waits for another hour and then tries each hour that had a returned value of 0 until a value is returned. The latest timestamp to return a value that is not 0 is then set as the 'start point' to continue looping through each hour from then to now to return the data and store it in home assistant using a statistic rather than a current sensor.
