Charging issue with Zappi and Powerwall

Powerwall and Octopus intelligent issues-

Sorry to come back but I have a new problem now as soon as I moved to Octopus intelligent tariff.

I have 3 Powerwalls and the charger is supplied via Powerwall, so it sits between grid and charger.

This set up is fine for fixed off peak tariff as Powerwall lets grid charge the car and charges itself in that off peak time.

However, on Octopus intelligent , when I plug in the car, the Powerwall starts charging the car as per octopus intelligent schedule and starts draining Powerwall.

I have checked with Tesla installer and he says that all installation they do has Powerwall installed in a way that it sits between grid and all electrical supply to house. They have not encountered this issue as all battery storage systems use off peak tariff (in which most people charge both cars and battery) and only Octopus intelligent tariff has smart charging as well as off peak supply so you can charge battery at off peak time but car anytime via app.

The quick solution is to connect car charger directly to mains and I asked the installer if we can connect charger directly to mains so that Powerwall does not control the charger but he has not done it before.

Has anybody else have a set up with battery storage independent of car charger and does it work fine?

I have had The octopus intelligent with Zappi 2 installed this week and after some messing about found that the best way for the Octopus intelligent to work, (which is the most cost efficient method to charge the car) is to put Zappi in fast mode, delete any schedules on the car or Zappi and let OI set up an intelligent timer each night. You need to put in your ready time and min % and plug the car in. Initially it will charge and I have heard this can go in for a few mins, but for me so far it just takes a min to crate the intelligent schedule and it then stops charging.

I only use the Eco + during the day when the solar PV is generating enough electricity to free charge the car. Hope this helps / works.
