Change the state for helper - schedule

I use a scheduler helper in my automation as a trigger. This works well.
I’d like to change the state from the scheduler helper to “on”, based on another trigger.
So I was hoping for a service call or something to change the state. something like:

service: scheduler.turn_on ect…

Can someone point me in the right direction?

Thanks!

The Schedule integration offers just one service call:

schedule.reload

The state of a schedule entity changes to on only at the appointed time and date. The integration offers no service call to change a schedule entity’s state.

You will need to revise the design of whatever it is you’re trying to build.

Thanks for your time. I’ll do a redesign.
I tried to get a schedule for each Monday and Tuesday from14.00 till 18.00. Except for some dates in a year. Then it should be starting at 09.00.

Now I use the events from a Google calendar. With recurrence on Monday en Tuesday except for a few days (during holidays)
