Sykes Likewise, I have found it very difficult to 'unlearn' the old portal.
I don't think the new beta portal was properly writing changes I was making through settings, making for unpredictable behaviour. I kept bouncing back to the old portal to make things 'stick' and I'm sure that wasn't helping.
I recently managed to get my battery firmware to update after two or three abortive attempts. After that I hard powered-down my inverter and restarted it. Since then I have started using the beta portal and now seem to have a harmonious arrangement.
I have the 'Eco' setting running, along with Timed Charge between 23:30 and 05:30 - aligned to Octopus Intelligent and it now seems to be behaving.
So perhaps a classic "turn it off, then on again" might help?
