@Edent thought you might be interested in my latest experiment.
I have a python script that tries to optimise charging the house battery from the grid based on lowest cost (which is below export price) and grid carbon.
I wanted to see what it was working with and outputting. A chart like this gets sent to me over matrix twice a day.

Chart showing 24 hours across the x axis. A purple line shows electricity import costs which drop below 15p three times a day and peak at over 35p. A pink line shows co2 emissions. Blue bars dominate showing the charge rate of the battery in kW, they only appear during cheap times and are roughly inverted and magnified versions of the pink co2 line
