a few months ago I added sensors for my Energy Dashboard, and so far it has worked like a charm, but when I did it I created the sensors within a yaml file, and then added them to the board using the Add consumption and choosing the Sensor,
I have been talking with a friend that when I change my Tariff in a 18 months then all my history data will be change when I enter in the new values for the Gas and Electric.
so I would like to create a Helper and keep my history data as and when I move to a new tariff.
here is my problem, I when I added my helper, using the same senor name, I saw that the history data didn’t move over - so is there a way to do this, and move over to a helper and still keep my history data ?
