Input Datetime


The input_datetime integration allows the user to define date and time values that can be controlled via the frontend and can be used within automations and templates.

To add three datetime inputs to your installation, one with both date and time, and one with date or time each, add the following lines to your configuration.yaml:

# Example configuration.yaml entry
input_datetime:
  both_date_and_time:
    name: Input with both date and time
    has_date: true
    has_time: true
  only_date:
    name: Input with only date
    has_date: true
    has_time: false
  only_time:
    name: Input with only time
    has_date: false
    has_time: true

Configuration Variables

input_datetime

(map)(Required)

Alias for the datetime input. Multiple entries are allowed.

name

(string)(Optional)

Friendly name of the datetime input.

has_time

(boolean)(Optional)

Set to true if the input should have a time. At least one has_time or has_date must be defined.

Default value:

false

has_date

(boolean)(Optional)

Set to true if the input should have a date. At least one has_time or has_date must be defined.

Default value:

false

icon

(icon)(Optional)

Icon to display in front of the input element in the frontend.

initial

(datetime | time | date)(Optional)

Set the initial value of this input, depending on has_time and has_date.

Default value:

1970-01-01 00:00 | 1970-01-01 | 00:00

Attributes

A datetime input entity’s state exports several attributes that can be useful in automations and templates.

Attribute Description
has_time true if this entity has a time.
has_date true if this entity has a date.
year
month
day
The year, month and day of the date.
(only available if has_date: true)
timestamp A timestamp representing the time held in the input.
(only available if has_time: true)

Restore State

If you set a valid value for initial this integration will start with state set to that value. Otherwise, it will restore the state it had prior to Home Assistant stopping.

Services

Available service: input_datetime.set_datetime.

Service data attribute Format String Description
date %Y-%m-%d This can be used to dynamically set the date.
time %H:%M:%S This can be used to dynamically set the time.
datetime %Y-%m-%d %H:%M:%S This can be used to dynamically set both the date & time.

To set both the date and time in the same call, use date and time together, or use datetime by itself. Using datetime has the advantage that both can be set using one template.

Automation Examples

The following example shows the usage of the input_datetime as a trigger in an automation (note that you will need a time sensor elsewhere in your configuration):

# Example configuration.yaml entry
# Turns on bedroom light at the time specified.
automation:
  trigger:
    platform: template
    value_template: "{{ states('sensor.time') == (state_attr('input_datetime.bedroom_alarm_clock_time', 'timestamp') | int | timestamp_custom('%H:%M', True)) }}"
  action:
    service: light.turn_on
    entity_id: light.bedroom

To dynamically set the input_datetime you can call input_datetime.set_datetime. The values for date and time must be in a certain format for the call to be successful. (See service description above.) If you have a datetime object you can use its strftime method. Of if you have a timestamp you can use the timestamp_custom filter. The following example can be used in an automation rule:

# Example configuration.yaml entry
# Sets input_datetime to '05:30' when an input_boolean is turned on.
automation:
  trigger:
    platform: state
    entity_id: input_boolean.example
    to: 'on'
  action:
  - service: input_datetime.set_datetime
    entity_id: input_datetime.bedroom_alarm_clock_time
    data:
      time: '05:30:00'
  - service: input_datetime.set_datetime
    entity_id: input_datetime.another_time
    data_template:
      time: "{{ now().strftime('%H:%M:%S') }}"
  - service: input_datetime.set_datetime
    entity_id: input_datetime.another_date
    data_template:
      date: "{{ as_timestamp(now())|timestamp_custom('%Y-%m-%d') }}"
  - service: input_datetime.set_datetime
    entity_id: input_datetime.date_and_time
    data_template:
      datetime: "{{ now().strftime('%Y-%m-%d %H:%M:%S') }}"
  - service: input_datetime.set_datetime
    data_template:
      entity_id: input_datetime.date_and_time
      date: >
        {{ now().timestamp() | timestamp_custom("%Y-%m-%d", true) }}
      time: >
        {{ now().timestamp() | timestamp_custom("%H:%M:%S", true) }}
