OctopusFlex with a GivEnergy system

I'm considering switching from the standard Octopus tarriff to Flex. I have a GivEnergy system with a single 5kWh battery - but I'm not sure I can trust my family to remember to try to minimise useage during the peak cost 16:00 - 19:00 period.

My hypothesis then - aimed more at minimising any import during that period, rather than maximising export, is:

Set up my system to force import to fill the battery in the 'flux' period of 02:00 - 05:00, and to fill it again in the 15:00 - 16:00 hour each day, to try to make sure it's full before peak time starts. If it then exports any, all the better - but it should make it unlikely that we need to import.

First question for those in the know is:

Does this sound like a good compromise to using the flux tariff without having to be crazy strict with my family? I reckon this way I'll get good use out of the low cost overnight period, and will likely take advantage of the slightly higher export price during the day too. And if it's still sunny between 16:00 and 19:00, might even get some of the higher export price.

And second question is:

Can I set up this plan through the GivEnergy dashboard? I'm not very practiced at the more in depth settings. But I found the timed charge setting, but could only seem to set up one time of the day to force it to charge from the grid - I need two!

Cheers for any advice!
 
This is doable through Home Assistant (search for threads on this). Whether you can get it to work depends on a few things..
What inverter size have you got?
What's the current average usage between 4 and 7pm?
What's the current average battery SOC at 4pm?

In the peak period for instance, I force discharge the battery for about an hour which takes my 9.5kw battery down to usually 60% by just after 5pm.
We then use the oven etc which all.is a power draw within the capability of the inverter so the battery continues to be used. So no cost of import.

Showers after 7pm which always has to draw from grid as it's power is higher than inverter can cope with, but it's outside.of the peak window.

Charge battery again overnight
 
On a quick perusal, that's going to be way beyond me!

Thank you for the suggestion though. :)
There's a lot of support here and, to be fair, I thought it would be beyond me but with a little bit of time I've worked out how to get it to do what I need...
