Sun

This is an enhanced version of the standard Sun component. Without configuration additions it behaves exactly as the standard component. With configuration additions you can:

• Select which attributes sun.sun should have from the original set, as well as a few new ones.
• Control how often azimuth and elevation are updated.

Installation

See Installing and Updating to use Custom Updater.

Alternatively, place a copy of:

sun.py at <config>/custom_components/sun.py

where <config> is your Home Assistant configuration directory.

Then add the desired configuration. Here is an example of a typical configuration:

sun:
  monitored_conditions:
    - elevation
    - sunrise
    - sunset
  scan_interval:
    minutes: 10

Configuration variables

• monitored_conditions (Optional): A list of sun.sun attributes to include. Options from the standard component: azimuth, elevation, next_dawn, next_dusk, next_midnight and next_noon. New options: daylight, next_daylight, prev_daylight, sunrise and sunset. The default is to include the options from the standard component.
• scan_interval (Optional): If azimuth or elevation are included, then this controls how often they are updated. The default is the same behavior as the standard component (i.e., once a minute on the half minute.)

New attributes

Attribute	Description
daylight	The amount of time from today's sunrise to today's sunset (in seconds).
next_daylight	Same as daylight, except for tomorrow.
prev_daylight	Same as daylight, except for yesterday.
sunrise	Today's sunrise (in UTC).
sunset	Today's sunset (in UTC).

Caveats

elevation is used by the frontend. You can choose to exclude it if you don't care about it, especially if you don't display sun.sun in the frontend. If you do display it in the frontend and choose to exclude elevation, then its value will just be blank.

Example usage

Sensors

sensor:
  - platform: template
    sensors:
      sunrise:
        friendly_name: Sunrise
        value_template: "{{ as_timestamp(state_attr('sun.sun', 'sunrise'))|timestamp_custom('%X') }}"
      sunset:
        friendly_name: Sunset
        value_template: "{{ as_timestamp(state_attr('sun.sun', 'sunset'))|timestamp_custom('%X') }}"

      daylight_sec:
        friendly_name: Daylight Seconds
        value_template: "{{ state_attr('sun.sun', 'daylight')|int }}"
        unit_of_measurement: sec
      daylight_hr:
        friendly_name: Daylight Hours
        value_template: "{{ (state_attr('sun.sun', 'daylight')/(60*60))|round(2) }}"
        unit_of_measurement: hr
      daylight_hms:
        friendly_name: "Daylight HH:MM:SS"
        value_template: >
          {{ state_attr('sun.sun', 'daylight')|int|timestamp_custom('%X', false) }}

      daylight_chg:
        friendly_name: Daylight Change from Yesterday
        value_template: >
          {{ (state_attr('sun.sun', 'daylight') - state_attr('sun.sun', 'prev_daylight'))|int }}
        unit_of_measurement: sec

      daylight_remaining_min:
        friendly_name: Daylight Remaining Minutes
        entity_id: sensor.time
        value_template: >
          {{ ((as_timestamp(state_attr('sun.sun', 'sunset')) - now().timestamp())/60)|int }}
        unit_of_measurement: min
      daylight_remaining_hm:
        friendly_name: "Daylight Remaining HH:MM"
        entity_id: sensor.time
        value_template: >
          {{ (as_timestamp(state_attr('sun.sun', 'sunset')) - now().timestamp())
             |timestamp_custom('%H:%M', false) }}

Note that the last two examples use now() in the template. However, this by itself will not cause the template sensors to update when time changes. So we need some way to get them to update. By configuring sensor.time (see Time & Date), we can use that via the entity_id parameter to force the template sensors to update once a minute.
