It’s a Hypervolt charger that I have and I don’t know how to tell if it’s wired grid side or not.
If it’s wired grid side, Fogstar won’t see the charger – I, expect it is, as from memory you have a dedictated consumer unit for the charger.
Octopus will want to see power flowing into the car.
Home Assistant is great, if you want to make your home snart ie powered curtains, rad valves, sockets etc, but outside of this it can become more complicated and open a can of worms, even though the coding is readilly availailable to hust download directly into HA. In a remotely similar way, it’s like side loading app onto a Firestick, once you know how it becomes easy and your able to go on and challenge, if the app or the coding in the case of HA as bug for example. I use Arduino, which is perhaps more complicated, but could be done more cheaply of one board.
Nipping out now I’ll come back later 🙂
@Rico are you around?
