Turn lights on depending on sun angle and weather conditions?

When it goes below 1 - works not too bad; needs a bit of tweaking. I took all the values and averaged them, seems to work somewhat more timely but it’s definitely WIP

sensors:
      ambient_light:
        friendly_name: 'Ambient Light'
        value_template: '{{ "%.2f"|format((states.sun.sun.attributes.elevation/24)*((states.sun.sun.attributes.elevation/24)+(1-(states.sensor.dark_sky_cloud_coverage.state|int/100)))) }}'

I know this is a real old thread, but have you made any advancements in this template? I’m looking to do exactly this and your template seems to be the best solution I’ve found so far aside from putting an ambient light sensor outside.

Not really – I still use elevation but it’s fixed and I factor in lux from my pir’s as well:

    - platform: state

    - condition: or
      conditions:
      - condition: template
        value_template: "{{ states.sensor.kitchen_pir_lux.state | int <= 22 }}"
      - condition: template
        value_template: "{{ -6 < states.sun.sun.attributes.elevation | int < 10 }}"
