Do fan cards now support 4 speeds? The original design decision by @wilburCforce was to match what the UI supported.

[wilburCforce]

When I inquired with the architects I was told that the fan card would never support 4 speeds. This part of the integration only serves to drive the UI and doesn't impact functionality of the four speeds. You can still set the speed by percentage and create your own cards to present that in the UI. Here is a super rough example I put together:

type: vertical-stack
title: Bedroom Fan
cards:
  - show_name: true
    show_icon: true
    type: button
    tap_action:
      action: call-service
      service: fan.set_percentage
      target:
        entity_id: fan.master_bedroom
      data:
        percentage: 100
    name: High
    icon: mdi:fan-speed-3
    show_state: false
    icon_height: 50px
  - show_name: true
    show_icon: true
    type: button
    tap_action:
      action: call-service
      service: fan.set_percentage
      target:
        entity_id: fan.master_bedroom
      data:
        percentage: 80
    name: Med High
    icon: mdi:fan-speed-3
    show_state: false
    icon_height: 50px
  - show_name: true
    show_icon: true
    type: button
    tap_action:
      action: call-service
      service: fan.set_percentage
      target:
        entity_id: fan.master_bedroom
      data:
        percentage: 40
    name: Medium
    icon: mdi:fan-speed-2
    show_state: false
    icon_height: 50px
  - show_name: true
    show_icon: true
    type: button
    tap_action:
      action: call-service
      service: fan.set_percentage
      target:
        entity_id: fan.master_bedroom
      data:
        percentage: 15
    name: Low
    icon: mdi:fan-speed-1
    show_state: false
    icon_height: 50px

I understand the limits imposed by the HA fan card architecture. It is disappointing they will not be supporting >3 speeds.

Thank you for the proposed template
