Problem with sensor for dusk to dawn timing

dzlhub · September 25, 2024, 3:33am

Hi,

I am trying to create a template sensor which detects Dawn, Day, Dusk, Night, Late Night and changes state, icon, icon colour. I am using CustomUI and have been researching this for the last few days and am at a loss on how to get it work.

packages/lighting/light_sensors.yaml

sensor:
  - platform: template
    sensors:
      day_night:
        friendly_name: "Day/Night"
        unique_id: day_night
        state: >
          {% set elevation = state_attr('sun.sun', 'elevation') %}
          {% set rising = state_attr('sun.sun', 'rising') %}
          {%- if elevation <= -2 & rising = false -%}
            Dusk
          {%- if elevation <= -50 & rising = false -%}
            Night
          {%- if elevation <= -60 & rising = false -%}
            Late Night
          {%- elif elevation > -2 & rising = true -%}
            Dawn
          {%- else -%}
            Day
          {%- endif -%}
        icon: >
          {% set elevation = state_attr('sun.sun', 'elevation') %}
          {% set rising = state_attr('sun.sun', 'rising') %}
          {%- if elevation <= -2 & rising = false -%}
            mdi:weather-sunset-down
          {%- if elevation <= -50 & rising = false -%}
            mdi:weather-night
          {%- if elevation <= -60 & rising = false -%}
            mdi:weather-night
          {%- elif elevation => -2 & rising = true -%}
            mdi:weather-sunset-up
          {%- else -%}
            mdi:weather-sunny
          {%- endif -%}
        attributes:
          icon_color: >
            {% set elevation = state_attr('sun.sun', 'elevation') %}
            {% set rising = state_attr('sun.sun', 'rising') %}
            {%- if elevation <= -2 & rising = false -%}
              rgb(217, 143, 0)
            {%- if elevation <= -50 & rising = false -%}
              rgb(9, 38, 184)
            {%- if elevation <= -60 & rising = false -%}
              rgb(39,38,84)
            {%- elif elevation => -2 & rising = true -%}
              rgb(255, 168, 0)
            {%- else -%}
              rgb(255, 249, 0)
            {%- endif -%}

Use supported symbols and operators in your templates:
- Use and, not &. Jinja Docs - Logic operators
- Single equals symbol, = are for use in set statements. Double, == must be used for equality comparisons. Jinja Docs - Comparison symbols.
Only one if is supported, use elif if you need multiple test statements. Jinja Docs - If statements

{% if  ....%}
{% elif  ....%}
{% else  ....%}
{% endif  ....%}

The template needs more specific ranges and/or specific order. The template will return “Dusk” for the majority of the night before solar midnight. This is because of the broad range, and the order in which that if clause is tested. To define a more specific range you can do something like:

...
{%- if -18 < elevation <= -2 and not rising -%}
  Dusk
....

Besides, you are mixing up new (integration) and legacy (platform) template sensor yaml.
Choose one or the other

Ok, I have made changes trying to follow

template:
  - sensor:
  ## Day/Night ##
    - name: "Day/Night"
      state: >
        {% set elevation = state_attr('sun.sun', 'elevation') %}
        {% set rising = state_attr('sun.sun', 'rising') %}
        {% if -2 < elevation <= 2 and not rising %}
          Dusk
        {% elif -50 < elevation <= -2 and not rising %}
          Night
        {% elif -60 < elevation <= -50 and not rising %}
          Late Night
        {% elif -2 > elevation => 2 and rising %}
          Dawn
        {% else %}
          Day
        {% endif %}
      icon: >
        {% set elevation = state_attr('sun.sun', 'elevation') %}
        {% set rising = state_attr('sun.sun', 'rising') %}
        {% if -2 < elevation <= 2 and not rising %}
          mdi:weather-sunset-down
        {% elif -50 < elevation <= -2 and not rising %}
          mdi:weather-night
        {% elif -60 < elevation <= -50 and not rising %}
          mdi:weather-night
        {% elif -2 > elevation => 2 and rising %}
          mdi:weather-sunset-up
        {% else %}
          mdi:weather-sunny
        {% endif %}
      attributes:
        icon_color: >
          {% set elevation = state_attr('sun.sun', 'elevation') %}
          {% set rising = state_attr('sun.sun', 'rising') %}
          {% if -2 < elevation <= 2 and not rising %}
            rgb(217, 143, 0)
          {% elif -50 < elevation <= -2 and not rising %}
            rgb(9, 38, 184)
          {% elif -60 < elevation <= -50 and not rising %}
            rgb(39,38,84)
          {% elif -2 > elevation => 2 and rising %}
            rgb(255, 168, 0)
          {% else %}
            rgb(255, 249, 0)
          {% endif %}

and now getting the error:

Jinja Docs - Comparison symbols

Troon · September 27, 2024, 2:06pm

Read the error message, and check the code you’re posting is live. The error is moaning about your incorrect use of <== and ==>, but these symbols don’t appear in the code you’ve posted above.

Per Drew’s link, you want >= (greater than or equal to) and <= (less that or equal to).

dzlhub · September 27, 2024, 2:21pm

I have fixed it, and the sensor is now appearing in Helpers.
Its state is now reporting as Day.

Attributes:
Icon color rgb(255, 249, 0)

The icon colour is not changing though.

My current time is 00:21

Troon · September 27, 2024, 2:35pm

Can you point to the documentation that explains how your icon_color attribute works?

dzlhub · September 27, 2024, 2:40pm

I’m using Custom UI and Custom Icon Color

github.com

Mariusthvdb/custom-ui/blob/b387852ff73d90534dd4c59b72aabd0fa4dcb7c3/EXAMPLES.md

# Some examples using custom-ui.

This is an excerpt of my own package, and can be used
directly if you copy it to your own homeassistant structure and activate packages. Of
course other methods work also, like pointing to a dedicated customize file, and
referencing that in your configuration.yaml

# Always use a guard (for unexpected states).
Of course this holds for Jinja templates in HA too...
The guard is used by setting the `else` clause, which in the examples below are on the
last lines, starting with 'return'. Dont need to use the word `else` itself, though it
will be valid if you do.

Lastly, remember to delimit the lines with a `;` .

Why use custom-ui? 2 huge reasons:

# Icon color

Setting a color for an icon is not possible in core HA. There is no attribute `icon_color` out of the box.

Mariusthvdb/custom-icon-color/blob/0935ded7f9d6956b8844fb74fed9eca71e43d18a/EXAMPLES.md

# Some examples using custom-ui-icon-color.
(using custom-ui with templating is explained [here](https://github.com/Mariusthvdb/custom-ui/blob/master/EXAMPLES.md))

# Icon color

Setting a color for an icon is not possible in core HA. There is no attribute `icon_color` out of the box.

Personally, I can't live without the `icon_color` attribute. Fully aware of the modern days custom card-mod, with which you can set a style on any card and entity, this still doesn't come close to the ease of custom-ui-icon-color. 
Keeping as many styling issues out of the Lovelace cards makes for much better readable configs (imho) and, last but not least: using custom-ui-icon-color we can set colors and do so globally. 

Declare once, use everywhere. 

Also significant: setting the attribute icon_color makes it show up in any more-info panel.

The color in the custom-ui-icon-color can take any CSS color value. For example: #FFACAC, red, rgba(10, 20, 30, 0.5) etc.
Note that the color will be applied as-is and it won't be affected by the brightness attribute.

# Templates
Core HA customizing is straightforward and can't use templates based on states or attributes. This plugin can not do that either.

Sorry it’s taken me so long to reply. Been busy with work. I did end up going through the code and modifying to reflect the integration template sensor jinja.

dzlhub · October 1, 2024, 3:49am

Seeing as I can’t mark multiple solutions. Thanks everyone for your help. I have the template sensor working now. My next step is to figure out templating for input booleans.
