Lovelace Horizon Card

A Home Assistant Dashboard Card available through the Home Assistant Community Store and inspired by Google Weather.

Lovelace Horizon Card is a fork of the original home-assistant-sun-card project by @AitorDB to continue the great work and distribute the responsibility of supporting and advancing the project among a team of people.

Introduction

The Horizon Card tracks the position of the Sun and the Moon over the horizon and shows the times of various Sun and Moon events, as well as their current azimuth and elevation, in a visually appealing and easy-to-read format.

How it works

The card will show the Sun and the Moon as they travel across the horizon from East to West. Both celestial bodies will be shown when above or below the horizon.

The current view shows a period of 24 hours centered around the local solar noon. This means that the Sun will continue to travel to the far end of the graph until it reaches solar midnight, which may be some time before or after midnight in your local time zone. Once solar midnight is reached, the view will reset and start showing the data for the next day.

In the Northern hemisphere, East is on the left, South is in the middle (when the Sun is in its highest position), and West is on the right. You are facing South and the Sun travels left-to-right.

In the Southern hemisphere, West is on the left, North is in the middle (when the Sun is in its highest position), and East is on the right. You are facing North and the Sun travels right-to-left. You can disable the direction flip by setting southern_flip: false.

The elevation of the Sun follows a predetermined curve that approximates the actual elevation, while the elevation of the Moon affects its vertical position in the graph. The scale for the Moon elevation is logarithmic, so lower elevations will appear higher (above horizon) or lower (below horizon).

If showing the moon phase is enabled, the icon will be rotated to match the approximate view for your latitude. You can disable this by setting moon_phase_rotation: 0 or set a different angle to match your location or preferences.

Installation

Please ensure you have HACS and the Sun integration enabled in your Home Assistant setup.

If you have My Home Assistant configured, simply click here:

Otherwise follow these steps:

1. Make sure the HACS component is installed and working.
2. Search for "Horizon Card" or lovelace-horizon-card in HACS and install the latest version.

Manual Installation

Installation via HACS is recommended, but a manual setup is supported.

1. Download the latest lovelace-horizon-card.js file.

2. If necessary, create a www folder in your configuration folder (where configuration.yaml is found).

3. Copy the downloaded file into your www folder.

4. Add the resources, depending on whether you manage your Lovelace resources via the UI or YAML:

   1. UI: Go to and click Add resource (or navigate to Settings -> Dashboards -> Resources -> Add Resource) and enter:

      URL: /local/lovelace-horizon-card.js

      Type: JavaScript Module

   2. YAML: Add the configuration to your ui-lovelace.yaml:

      resources:
        - url: /local/lovelace-horizon-card.js
          type: module
      

5. Restart Home Assistant.

Setup

Using UI

1. Access your dashboard, enter edit mode, and click on Add card. You should be able to find Custom: Horizon Card in the list.
2. In the UI editor, customize the card by modifying its configuration as detailed in the Config section below.

Note: If Custom: Horizon Card doesn't appear, clear the cache and reload the page.

Using YAML

1. Add a new card with type: custom:horizon-card to your cards list and include any additional configuration from the Config section below.

Note: If you encounter an error like Custom element doesn't exist, clear the cache and reload the page.

Caveats

The Moon phase name (if the field moon_phase is enabled) is obtained via the Moon integration. If the integration is not installed, the card will still show the Moon phase as a human-readable constant followed by (!), e.g., waning_gibbuous (!). Due to the way Home Assistant works, the localized Moon phase name will always be in Home Assistant's language and not in the language set for the card via the language option.
