Air Touch 4 automation issues


I have set up my AirTouch 4 - it has connected to the main unit and all dampeners etc - however now I am trying to set up automation it doesn’t work. can anyone possibly assist?

- id: '1636173817353'
  alias: A/C Temp
  description: ''
  - platform: numeric_state
    entity_id: climate.master
    attribute: temperature
    above: '23'
      hours: 0
      minutes: 0
      seconds: 5
      milliseconds: 0
  - condition: device
    device_id: *removed*
    domain: climate
    entity_id: climate.ac_0
    type: is_hvac_mode
    hvac_mode: cool
  - delay:
      hours: 0
      minutes: 30
      seconds: 0
      milliseconds: 0
  - device_id: *removed*
    domain: climate
    entity_id: climate.ac_0
    type: set_hvac_mode
    hvac_mode: 'off'
  mode: single

So My aim here is when the temp in the bedroom gets above 23 degrees then turn on the AC for 30 mins then back off - however it won’t seem to do it, I can turn the AC on manually through HA with no issues.

I don’t think even doing this is effective anyway.
Let the controller do the work and just set a temperature and let it maintain it.
I don’t see the point In letting the room either heat up or cool down and then it’s costing more to run it again.
