Sunday special programming

Hi. I normally fill up my 9.5kWh Givenergy battery every day between midnight and 5am on cheap rate with British Gas, and then use that through the day until empty and we're back on peak grid (around 4pm most days). I've just signed up to this from British Gas - https://www.britishgas.co.uk/energy/peak-save/sunday.html
Which gives me half price peak rate between 11-4 on Sundays. The question is how do I automate filling my battery up during this time? The automation on the app doesn't seem to allow me to set up a scene for Sunday daytime only. It seems to only have 'hour of day' for every day, rather than 'day of week' functionality. Unless I'm missing something?

Thanks

Maybe you will have to try a 3rd party app such as
Octo R&D scheduler
WonderWatt
I cant say if they will do what you want

HomeAssistant may offer more options of automations but I have only ever used daily functions, and not day of the week
Others will know better than me

@Davenlyd SteveCook is correct, the GivEnergy app won’t allow you to do day of the week scheduling, you’ll need a 3rd party product, or manually change the schedule every week.

Sorry

Thanks both. Have suggested it as a feature through app feedback

Good luck with that.........

Davenlyd As @SteveCook says, no chance.

I have raised bug reports and feature requests via the app going back to February 2023 and not a single response to any of them.
