My index doesn’t move in November, which is normal since the first red Tempo day was 29/12/25.
I’ll look at the tutorial by @pierre-gilles to extract the data from the db for each of my Tempo indexes.
EDIT :
I just retrieved the values from 11/11/25 to check what happened and I have an erroneous value that was recorded (800 kWh too much) so the visual is correct 
Is there a way to change/delete this value?
