Current various label attributes are available via templates, but not the new(ish) description field. For example:
{{ labels() }} # ['christmas_decorations', 'energy_saver', 'security']
{{ labels("living_room") }} # ['christmas_decorations', 'energy_saver']
{{ labels("my_device_id") }} # ['security']
{{ labels("light.christmas_tree") }} # ['christmas_decorations']
{{ label_id('Energy saver') }} # 'energy_saver'
etc…
I would like to be able to retrieve the description in a template e.g:
{{ label_decsription('energy_saver') }} # 'Energy saver description'
