That means charging your car or consuming your energy while making money instead of paying it. But current energy supply contracts only allow day-ahead hourly prices at best, giving less return. Maybe HA can partner up with an energy supplier to make those prices available for optimisations to the community? Probably an energy supplier in each country. With a kind of Octopus Agile product setup?
