Input weekday	Instructions on how to use the input weekday helper with Home Assistant.	Automation Helper	2025.11	internal	@home-assistant/core	input_weekday	helper

The Input weekday helper integration allows you to define a selection of weekdays that can be controlled via the user interface and used within conditions and triggers of an {% term automation %}. This makes it easy to dynamically manage weekday-based automations without having to manually specify weekdays in your automation configuration.

Configuration

The preferred way to configure input weekday helpers is via the user interface, in which they are known as Weekday Helpers. To add one, go to {% my helpers title="Settings > Devices & services > Helpers" %} and click the add button; next choose the {% my config_flow_start domain="input_weekday" title="Weekday" %} option.

To be able to add Helpers via the user interface you should have default_config: in your {% term "configuration.yaml" %}, it should already be there by default unless you removed it. If you removed default_config: from your configuration, you must add input_weekday: to your {% term "configuration.yaml" %} first, then you can use the UI.

Input weekdays can also be configured via {% term "configuration.yaml" %} file:

{% configuration %} input_weekday: description: Alias for the input. Multiple entries are allowed. required: true type: map keys: name: description: Friendly name of the input. required: false type: string weekdays: description: List of initially selected weekdays. required: false type: list default: a previous value is restored if available icon: description: Icon to display in front of the input element in the frontend. required: false type: icon {% endconfiguration %}

# Example configuration.yaml entry
input_weekday:
  work_days:
    name: Work days
    weekdays:
      - mon
      - tue
      - wed
      - thu
      - fri
    icon: mdi:briefcase

Valid weekday values are: mon, tue, wed, thu, fri, sat, sun.

Actions

This integration provides the following {% term actions %} to modify the state of the input_weekday and an action to reload the configuration without restarting Home Assistant itself.

Action	Data	Description
set_weekdays	weekdays	Set the selected weekdays (replaces all current selections)
add_weekday	weekday	Add a single weekday to the selection
remove_weekday	weekday	Remove a single weekday from the selection
toggle_weekday	weekday	Toggle a single weekday (add if not selected, remove if selected)
clear		Clear all selected weekdays
reload		Reload input_weekday configuration

Automation examples

Here's an example of an automation using the above input_weekday in a time trigger. This automation will only trigger on the selected weekdays.

automation:
  alias: "Weekday alarm"
  triggers:
    - trigger: time
      at: "07:00:00"
      weekday: input_weekday.work_days
  actions:
    - action: light.turn_on
      target:
        entity_id: light.bedroom

You can also use an input_weekday in a time condition:

automation:
  alias: "Weekday notifications"
  triggers:
    - trigger: state
      entity_id: binary_sensor.motion_detected
      to: "on"
  conditions:
    - condition: time
      weekday: input_weekday.work_days
  actions:
    - action: notify.mobile_app
      data:
        message: "Motion detected on a work day"
