Schedy - turn on / turn off with different schedules-entries? Don't want Schedy to turn on again after reboot

Configuration

Hi,

This is my schedule with schedy:

  rooms:
    kitchen:
      actors:
        switch.wzpwr:
      schedule:
        - { v: "on", start: "05:00", end: "07:30", weekdays: 1-5 }
        - { v: "off" }
      watched_entities:

This works nicely to turn on my coffy maker at 5:00 and turns it off at 7:30 - but
if I turn of the coffee-maker earler (at 6:00) and my home-assistant reboots than schedy will re-evaluate and turn on the coffee maker again and will leave it running until 7:30…

What I need is to turn on the coffee maker at 5:00 (automatically) and not re-evaluate if I have decided to turn it off earlier.
If the coffee maker is still on at 7:30 than schedy should turn it off.
If tried this, but it would not turn it off…

schedule:
        - { v: "on", start: "05:00" }
        - { v: "off", start: "07:30" }

It switches the coffee-maker on, but would not switch it off.
Anyone a good suggestion for me - am I thinking in the complete wrong direction?

Thanks!
Albert
