Helper for time ranges to use in automation

Configuration
1

Trying to be able to set a time in UI and pass it into an automation (to turn something on/off)

I think I need to use a input_number helper whitch kind of workk, if I set range from 0-2359 but not ideal, I can set the helper varable but would really like something a bit more user frendly (i.e. some type of clock widgget). In the UI I use something like this

type: entities
entities:
  - entity: input_number.ch_morning_on

In the automation I currently have

trigger:
  - platform: time
    at: "20:01:00"

how do I use the helper varable here

Haybe these is some type of custom helper?

PS I found this that may be usefull but dont quiote underastand how to use it.

Yes. It’s a great option. You can play a doorbell MP3 to the speaker. You can also make speaker groups with multiple speaker playing in sync throughout the home. Cheap and simple.
