Hourly Weather Card by @decompil3d

An hourly weather card for Home Assistant. Visualize upcoming weather conditions as a colored horizontal bar.

Installation

Easiest method:

✨ Install via HACS

Alternative method:

1. Download hourly-weather.js from the Releases page
2. Upload to /www/hourly-weather/hourly-weather.js (via Samba, File Editor, SSH, etc.)
3. Visit the Resources page in your Home Assistant install and add /hourly-weather/hourly-weather.js as a JavaScript Module.
4. Refresh your browser

Usage

This card will show in the "Add card" modal. It has a GUI editor for configuring settings.

If you prefer YAML, here is a sample config:

type: custom:hourly-weather
entity: weather.my_weather_entity
num_segments: 18 # optional, defaults to 12
name: Next 18 hours # optional, defaults to "Hourly Weather"

Choosing the right entity

This card is focused on displaying hourly weather data. It will work with coarser- or finer-grained data, though. I've tested with the OpenWeatherMap integration using the onecall_hourly mode and that works very well.

As of Home Assistant 2023.9.0, most weather integrations provide data in multiple time increments. If your weather entity provides hourly data, the card will use that by default. Otherwise, the card will attempt to use the finest-grained increments available, unless you have configured otherwise.

ℹ️ NOTE: If your selected weather entity provides forecasts in increments of greater than one hour at a time, each segment of the bar will be for one segment, not one hour.

Prior to Home Assistant version 2023.9.0, if you already use OpenWeatherMap for daily data, you can add a second integration of the same component for hourly -- just adjust the latitude or longitude a tiny bit (i.e. change the last decimal by 1). Otherwise, the integration may complain of a duplicate unique ID.

Options

Note that some of the more advanced options are not available in the card editor UI and must be configured via YAML.

Templating

The following options allow Home Assistant Jinja templates as values:

• name
• num_segments
• offset
• label_spacing

You may use any valid template expression that produces a string or number. For example, you can define offset based on the current time of day so that you see the next day's weather:

name: Tomorrow
num_segments: 24
offset: |
  {{ 24 - now().hour }}
label_spacing: 4

Or maybe show the rest of today's weather:

name: Today
num_segments: |
  {{ 24 - now().hour }}
label_spacing: |
  {% set segments = 24 - now().hour %}
  {{ 4 if segments > 12 else 2 }}

Action Options

Color Options

colors is specified as an object containing one or more of the keys listed below and values that are valid CSS colors or objects of foreground and/or background valid CSS colors. Invalid color values will be discarded and will trigger a warning.

Color value format

Colors may be specified as a valid CSS color string or as an object with one or more of the following fields, each containing a valid CSS color string:

• foreground: The color of the condition label text or icon
• background: The color of the bar background during that span

If color is specified as a plain string, it will be used for background. Foreground color defaults to the primary text color in your Home Assistant theme.

Some conditions will default to whatever the value is of some other condition. For example, fog will default to whatever cloudy is.

Sample colors configuration

colors:
  sunny: '#bbccee' # note that hex colors must be quoted
  snowy-rainy: rgba(255, 255, 255, 0.8) # rgba works (and hsla too)
  exceptional: red # as do valid CSS color names
  windy:
    background: lightgray
    foreground: '#000'

Wind Options

show_wind can be one of the following values:

• false Don't show wind speed/direction (default)
• true Show both wind speed and direction
• speed Only show wind speed
• direction Only show wind direction
• barb Show wind direction as a wind barb arrow
• barb-and-direction Show wind direction as a wind barb arrow and also show textual direction
• barb-and-speed Show wind direction as a wind barb arrow and also show speed
• barb-speed-and-direction Show wind direction as a wind barb arrow and also show speed and textual direction

Note: If your weather entity uses cardinal directions (e.g. 'N', 'SW', etc.) rather than numeric degrees for wind_bearing, the barb option is not supported and will result in an error.

Date Options

show_date can be one of the following values:

• false Don't show date (default)
• boundary Show date at the boundary between days
• all Always show date

Icon Fill Options

icon_fill can be one of the following values:

• single Show one icon per forecast span (default)
• full Show one icon per forecast segment
• <n> (an integer). Show icons every n-th forecast segment (will show at least one icon per forecast span)

NOTE: If a forecast segment is not wide enough to fit an icon, the icon will not be shown. That means that on narrow screens or with many segments, you may not see all icons. If that happens, consider using a larger numeric value for icon_fill or use single to show one icon per forecast span.

Upgrades

Version 3 ➡️ 4

In version 4.x, the num_hours option was deprecated in favor of num_segments. This simplifies the card and makes it clear that it operates on whatever size forecast segment your entity provides. The num_hours option still works, but num_segments takes precedence, if set. num_hours will be removed in a later major version of the card.

Version 4 ➡️ 5

In version 5.x, the DOM structure of the weather bar and its labels was changed to allow for odd-numbered segment counts and label spacing. Labels now appear centered with the segment they are representing, and the first label shown on the bar represents the first segment of data where in prior versions labels would begin at the second segment. This change may cause some custom CSS to break. If you have custom CSS, you may need to adjust it to account for the new structure.
