What Predbat entities are created to set charge start and end times?

[punkymuzzle]

Hi all
This app is great but unfortunately doesn't fully work with my inverter (Solax X1AC).
I've requested for help to get support for my inverter incorporated into Predbat https://github.com/springfall2008/batpred/issues/871 but nothing's been started yet, so I'm trying to do as much as possible myself.

I have managed to set it up so it's monitoring and predicting OK (the table is showing charging and discharging slots) - However, predbat isn't able to actually drive my inverter to charge / discharge the battery.

So I though I'd have a go at setting my own automations to charge the battery in line with Predbat predictions.
However, I don't know what triggers to use to identify the charging times. The nearest I've got to is this:

And my table looks like this, only I don't know what the underlying entity below the "Charge" notification is:

But as you can see there's no information being presented into this entity, and it's beyond me to try and troubleshoot the issue on my own.

One of my modes in my Inverter is for "Forced Time Use", which essentially charges the battery at set times (I have two slots I can programme), then it discharges and feeds the grid during the rest of the time. So I think this might be my best bet to try and mimic some of the Predbat functionality.

Would be really grateful if someone could help to get me charging in line with the Predbat table.
Many thanks in advance.
