Quick little template I came up with to show time and weather conditions
custom_header:
button_text:
options: >-
{{ hours12 }}:{{ minutesLZ }} {{ ampm }} - <ha-icon icon='mdi:weather-{{
states.weather.dark_sky.state }}'></ha-icon> {{
states.weather.dark_sky.attributes.temperature }}°
compact_mode: true
Note: The icon will not render when partlycloudy as that icon is weather-partly-cloudy. You could create a template sensor to overcome that
