Today we have the this for the tibber integration:
Once a day a statistics with hourly consumption and cost data is generated that can be used in the Energy Dashboard. (The ids are tibber:energy_consumption_HOMEID and tibber:energy_totalcost_HOMEID )
It would be nice to see the cost/money per kWh that day/week and so on.
Today the tibber:energy_totalcost_HOMEID includes the monthly fee. Maybe this can be discussed if it should be included in this statistic or not.
You can already get statistics for a week, month etc.
What i am missing if costs for each device but that need to be added in Home Assistant so nothing to do with the integration.
