I saw that the texts inside the graph are only english:

Add install/usage instructions for non yaml mode users.

Love your card, great work! One thing I would wish for:

To have in the status bar the option to not only call a service like today ("clean room X"), but to allow putting a clickable icon in there which will launch a new browser window with a pre-defined target. In essence mimicking what the famous "button card" offers:

• type: button
  tap_action:
  action: url
  url_path: IP

I know this would seem obvious to someone already using a thermostat, but for someone who is starting with this card to set up their first thermostat, it would be nice to suggest setting up the generic_thermostat in configuration.yaml.

Cheers, Richard

I would love to also use these for tunable whites. Can you support this?

I would love to see the setting for warm/cold white and different color for setting bright so this would look way better:

entities:
  - type: custom:rgb-light-card
    entity: light.light_gruppe_wohnzimmer
    justify: around
    colors:
      - brightness_pct: 0
        label: Aus
      - brig
