Using times within an entity to trigger events

Evening, I have just started with Home Assistant which is great, although a steep learning curve, particulary with YAML syntax.

Grateful of some pointers for how to write triggers based on an entity with times. I have a custom component that creates an entity as follows

entity name in development tab: octopus.timers

Data for the state in development tab is as follows.

timers:
  - entity_id: switch.ev
    times:
      '2021-01-09T19:30:00Z':
        params: null
        rate: 12.6
      '2021-01-09T20:30:00Z':
        params: null
        rate: 11.97

What I am looking to understand is how do I use this data within an automation
ultimately I am trying to send a rest command at each time.

However as the entity contains names of other entities I am totally confused. Thanks for any pointers
