Increment or decrement climate.set_temperature

I have searched but I really can’t find the answer to my problem, although I think I am very close

What I want is to create a switch that does the two rows below… is it possible using template switch or script?

{{ states.climate.fujitsu.attributes.temperature + 1 }}
{{ states.climate.fujitsu.attributes.temperature - 1 }}

This switch will then be used in an automation to keep the temperature on a certain level using my airconditioner

if the climatecomponent only had the setting it would be alot easier :S

I’m using sensor template, hope this helps

  tmp_living_calibrated:
    entity_id: sensor.tmp_living
    value_template: '{{ (float(states.sensor.tmp_living.state) - 1.5 ) }}'
    friendly_name: 'Living'  
    icon_template: mdi:thermometer
    unit_of_measurement: "°C"

cant make it work,

currently it looks like this but nothing happens when i press the script

'1538156619373':
  alias: Värmepump Temp +
  sequence:
  - data:
      entity_id: climate.fujitsu
      temperature: '''( {{ states.climate.fujitsu.attributes.temperature|int + 1 }}
        )'''
    service: climate.set_temperature
