There is something wrong with the template you have used in your template switch. Check it. It should be:
switch:
- platform: template
switches:
climatisation:
value_template: "{{ states('sensor.cupra_born_climatisation_state') in ['heating', 'cooling'] }}"
turn_on:
service: button.press
target:
entity_id: button.cupra_born_start_climate
turn_off:
service: button.press
target:
entity_id: button.cupra_born_stop_climate
And you should probably restart after changing it rather than just reloading yaml.
