Octopus want to do more than just turn the charging point on and off, they want to read the SoC (and possibly other stuff too).Why don't they get it working with pod point. It's a smart charger that works over net it turn charging on or off on command.
It's by far the most numerous charger surely.Every EV on my road has a pod point charger it's the one I see most frequently attached to houses.
The pod point chargers could easily be made to work but podpoint is owned by EDF so maybe they won't allow it. Or octopus don't want to because of this ?
