Sending continous telegram message until button press

Hey there
Today I purchased a fire alarm.
If this guy detects a fire a want to trigger the following:

  1. climate my car (if its frosty in winter)
  2. Honk my cars horn
  3. Send a telegram message to me and my wife

The steps 2 and 3 should be repeated every 30 seconds until I press a button inside the telegram message. Same goes for my wife. This means, if I press the button, my wife still gets messages until she presses it. And, of course, vice versa.

I have no idea how to put this inside an automation. (the button inside telegram message isn’t a porblem)
Maybe with 2 input_booleans representing if me or my wife pressed the button.
And then some automation repetition until the input boolean is true.
But in my thoughts I only get this working for 1 person.

Are there any ideas out there how to solve this problem?
