Used electricity metering
#1
Good afternoon. I have a task to record the readings of the electricity consumed every day, during the week and during the month, and according to this data, display the amount in euros for the electricity used. Can anyone advise how this can be done, the obtained values should be displayed in a mosaic, by day, weekly, monthly? The trend log stores the value once an hour.
I receive parameters via ModBus to virtual group addresses.

Use trends and then fetch the data by using this https://openrb.com/docs/trends-new.htm
then calculate your euros in script.
