Swing mode "both" of ac unit work with card type: thermostat by Home Assitant, but not with mini climate card

Configuration Frontend
1

Hi, i need some help cause i’m loosing my mind over this. I’ve also posted on reddit, without success for now.

I’m switching from che card type: thermostat by Home Assitant to the Mini Climate Card, and with the Mini Climate Card i can’t set the Swing of the AC to Both. Just off or vertically. It work just fine with the Thermostat card.

This is the log of the call_service:

With Thermostat card IT WORK:

event_type: call_service
data:
  domain: climate
  service: set_swing_mode
  service_data:
    entity_id: climate.condizionatore_letto
    swing_mode: both
origin: LOCAL
time_fired: "2025-10-09T11:06:03.394419+00:00"
context:
  id: 01K74ACGR2D5BVM700GGP37KRT
  parent_id: null
  user_id: ///

With Mini Climate Card IT DOESN’T:

event_type: call_service
data:
  domain: climate
  service: set_swing_mode
  service_data:
    entity_id: climate.condizionatore_letto
    swing_mode: both
origin: LOCAL
time_fired: "2025-10-09T11:06:11.962163+00:00"
context:
  id: 01K74ACS3T098PQYSSAR6HFVYQ
  parent_id: null
  user_id: ///

and this is the button configuration on the mini climate card (the vertical and off setting works):

buttons:
  swing_modes:
    style: "(value, entity) => ({ color: 'black !important' })"
    type: dropdown
    icon: mdi:approximately-equal
    state:
      attribute: swing_mode
    active: state => state !== 'off'
    source:
      "off": "Off"
      both: Both
      vertical: Vertical
    change_action: >
      (selected, state, entity) => this.call_service('climate',
      'set_swing_mode', { entity_id: entity.entity_id, swing_mode: selected })

The attribute of the entity it’s correct, i checked on the developer tools.

So:

  1. I think the code on the card is ok, cause the other two setting works, and ican see that the call_service is correct
  2. the ac unit can be set on swing mode both, it’s phisically possible and it’s an option name ‘both’ on the entity attributes
  3. the exactly identical call_service is made from the card type thermostat works

I’m really struggling on this one…
