Setting a heating schedule

[TheClyk]

Is your feature request related to a problem? Please describe.
I've looked in the automation and cannot see an option to set a heat schedule. I'm in the UK and have a cheap tarrif at night and would like to heat up the hot tub then overnight and let it cool until later on when we are ready to get in it. This will save the tub kicking in during the day so much that I pay a lot more for energy.

Describe the solution you'd like
Ability to set the temperature at say 40c at 12.30 am and then to 20c at 4.30 am when my tariff becomes more expensive.

Describe alternatives you've considered
None that I can see.

I appreciate this is an old question.
But I've done something similar using Automations.

See: https://www.home-assistant.io/docs/automation/basics/ on how to get started.
It's very easy, so when the time is 00:30, and between 00:30 and 04:00 - set your tub to heat.

Here is a very basic YAML.

- id: 'hot_tub_heating_control'
  alias: "Control Hot Tub Heating Based on Time Slot"
  description: "Turns on the hot tub heating between 00:00 and 05:30."
  trigger:
    - platform: time
      at: "00:00:00"
  condition:
    - condition: time
      after: '00:00:00'
      before: '04:30:00'
  action:
    - service: switch.turn_on
      target:
        entity_id: switch.hot_tub_heating

Then, have a second one to turn off the heating.

- id: 'hot_tub_heating_off'
  alias: "Turn Off Hot Tub Heating After Time Slot"
  trigger:
    - platform: time
      at: "04:30:00"
  action:
    - service: switch.turn_off
      target:
        entity_id: switch.hot_tub_heating

Great, thanks for this.
