Set Prog Time to 24h

[ciechomir]

I’m using an experimental dynamic tariff where low prices appear in different 15-minute periods throughout the day.
I would like to use a single slot (e.g., Prog1) to activate grid charging.

However, I can’t figure out how to set Prog1 Time so that it covers a full 24 hours (which would allow me to control Prog1 Capacity from Home Assistant whenever the price is low).

My question is:

a) How can I configure Prog1 Time to span 24 hours?
or
b) Is there a better approach to achieve this?
