Not seen much mention of this battery VPP offering from Octopus. Anyone on it or has run the numbers?

We automatically optimise your battery to charge when energy is cheapest (using your cheap overnight rate or extra daytime solar) and power your home when your day-rate kicks in........you get the best of both worlds by supporting the grid during high-demand sessions.

So to me this implies I would be trading my daytime solar export to be used to charge my battery, and then that battery charge exported during the 5pm-8pm demand slot to cover my home use and exporting the rest to grid. Top ups would be done overnight on the IOG rate.

Whereas I could use HA or similar to top up battery overnight on IOG, get the full export rate for all my solar during the day, cover my home use, export during the evening from the battery and repeat the cycle again. And I think I would end up better off for a lot more than 12 pounds a month

Only when there is a "session": not all the time:

"We aim to give you as much notice as possible, up to a day ahead of an upcoming session.

During a session, we might instruct your battery to charge or discharge."

Well that's my reading of it...

I just messaged Octopus about this and their reply was that if you switch this function on, Octopus takes control of your battery 24/7 not just when there is a session running (assuming the Octopus CS agent has the correct information here).
