Run shortcut or action on completion of timer?

Is it possible to run a shortcut on completion of a timer or to create a timer in a shortcut and have it wait for the timer to be complete to continue through the shortcut?

Thanks!

No. That sort of option doesn’t show on the list of triggers. You could set something to run a second Shortcut when prompted at a particular time maybe, or use something like Cronios.

If your period is short, you could set a timer and immediately wait, but you could also just wait and then play a noise.

Maybe if you were always in multiples of a period (e.g. 1 minute) and could 't use wait for that long, you could play a set piece of audio multiple times to avoid using wait and it timing out?

Depending on your use case, you could consider using an alarm instead, which I believe can be used as a trigger.
