Automation code for adjusting Air Conditioner temp

Configuration
1

Hi everyone. I want to create an automation that follows this logic.
What’s the best way to code this in an automation?

If outside temp <= 22 then set AC to 22

If outside temp =23 to 23.9 then set AC to 23

If outside temp =24 to 24.9 then set AC to 24

Etc …

- id: whatever
  trigger:
    - platform: state
      entity_id: sensor.outside_temp
  condition:
    - "{{ trigger.from_state.state not in ['unknown', 'unavailable', 'none'] }}"
    - "{{ trigger.to_state.state not in ['unknown', 'unavailable', 'none'] }}"
    - "{{ trigger.from_state.state != trigger.to_state.state}}"
  action:
    - service: climate.set_temperature
      target:
        entity_id: climate.your_climate_device_here
      data:
        temperature: >
          {% if states('sensor.outside_temp')|float <= 22 %}
            22
          {% elif 23 <= states('sensor.outside_temp')|float <= 23.9 %}
            23
          {% elif 24 <= states('sensor.outside_temp')|float <= 24.9 %}
            24
...etc
          {% else %}
           # your default value here
          {% endif %}

Note that what you asked for has a gap between 22 and 23 that will end up selecting the else case.

He does not want the decimal part. So, this instead?

        temperature: >
          {% set ot = states('sensor.outside_temp') | int %}
          {{ 22 if ot <= 22 else ot | int }}

Also I would include the conditions to prevent both unnecessary execution of the actions and to deal with the possibility of a non numeric state.

Thank you @tom_l !
This is what I added and it works as expected so far.

The template can be reduced to 2 lines (as shown above).

That’s what the final int does but you made me realize that if int is used initially, instead of float, then there’s one less filter needed.

        temperature: >
          {% set ot = states('sensor.outside_temp') | int %}
          {{ 22.5 if ot < 23 else ot }}

If there’s a need to limit the maximum temperature to 28 then it can be done like this:

        temperature: >
          {% set ot = states('sensor.outside_temp') | int %}
          {{ 22.5 if ot < 23 else ot if ot <= 28 else 28 }}

Just realized the template can be reduced to a single line:

    data:
      temperature: "{{ ([22.5, states('sensor.netatmo_village_high_indoor_outside_temperature')|int, 28]|sort)[1] }}"

Now you’re just showing off :slight_smile:

Nah, I just happened to recall this old post:
