Buttons style not updated on entity state

[RoboMagus]

I've spent some time creating the perfect little climate card for my needs, see config below, but it seems that the button icon colors as defined by each of their style: sections does not update when the entity is updated. E.g. I have it configured that when the climate state is set to auto, the auto button is highlighted green. This is the case when I freshly load the page or hit refresh. But when the state when loading the page is e.g. heat and by clicking the auto button the state changes to auto, all of the button colors stay as they are. However, the rest of the card does reflect this change...

Is that a bug, or something else I need to configure for this to function correctly?

Config:

type: custom:mini-climate
entity: climate.verwarming
name: Verwarming
icon: mdi:thermostat
card_mod:
  style: |
    .entity__icon {
      {% if is_state_attr(config.entity, 'hvac_action', 'off') %}
        color: var(--state-unavailable-color) !important;
      {% elif is_state_attr(config.entity, 'hvac_action', 'heating') %}
        color: var(--state-climate-heat-color) !important;
      {% else %}
        {% if state_attr(config.entity, 'current_temperature') >= state_attr(config.entity, 'temperature')  %}
          color: var(--state-icon-color) !important;
        {% else %}
          color: var(--state-climate-heat-cool-color) !important;
        {% endif %}
      {% endif %}
    }
    .entity__info__name_wrap {

I can confirm that this is an issue. I tried to fix it but currently can't as my expertise in front end is not that great. A PR will be more than welcome

Ok managed to find the issue. It is actually a bug in lit library that doesn't handle setting important on styles. (I will add a reference to a github issue later). To overcome it we need to do 3 things:

• override the state of each button, so it will not put the color attribute, which actually makes the important part crucial
• remove the important from all custom styels
• use entity.state in the custom style functions (as the first argument passed will now be the one we use in step 1)

This is very easy:

    state:
      mapper: |
        () => 'off';
    style: >
      (state, entity) => (entity.state == 'cool' ? { color:
      'var(--state-climate-cool-color)' } : { color:
      'var(--disabled-text-color)' })

Let me know if it works for you
