Button Custermise

Hi
I’m working on lovelace buttons as part of following switchs;


and pannel
Is there is a way to change the buttons that appear in right of volume to something other than lighting icons ?

Thanks for the tip, but how do I assign buttons.

switches:
  tv_panasonic_power:
    friendly_name: "Power"
    command_on: 'JgCYAXQ4EA0PKhANDw0PDg8N'
    command_off: 'JgCYAXQ4EA0PKhANDw0PDg8N'

If I got above buttons, how do I use cover to assign icon to command_on and command_off
can you please help me out a bit

Use scripts instead.

cover:
  - platform: template
    covers:
      hk_volume:
        friendly_name: "HK Volume"
        open_cover:
          service: script.hk_vol_up
        close_cover:
          service: script.hk_vol_down
        stop_cover:
          service: script.hk_vol_mute
        position_template: 50


script:
  hk_vol_up:
    sequence:
      - service: switch.broadlink_send_packet_192_168_xxx_xxx
        data:
          { "packet" : [ "JgBIAAABJZURExEUER...." ]}

  hk_vol_down:
    sequence:
      - service: switch.broadlink_send_packet_192_168_xxx_xxx
        data:
          { "packet" : [ "JgBQAAABJZUSEhEUER...." ]}

  hk_vol_mute:
    sequence:
      - service: switch.broadlink_send_packet_192_168_xxx_xxx
        data:
          { "packet" : [ "JgB4AAABJZUSEhEUER...." ]}

You’ll find the the switch.broadlink_send_packet... under Dev Tools/Services.
