### {% linkable_title Restore State %}
|
||||
|
||||
This component supports the `restore_state` function which restores the state after Home Assistant has started to the value it has been before Home Assistant stopped. To use this feature please make sure that the [`recorder`](/components/recorder/) component is enabled and your entity does not have a value set for `initial`. Additional information can be found in the [Restore state](/components/recorder/#restore-state) section of the [`recorder`](/components/recorder/) component documentation.
|
||||
|
||||
### {% linkable_title Services %}
|
||||
|
||||
This component provides a service to modify the state of the `input_datetime`.
|
||||
|
||||
| Service | Data | Description |
|
||||
| ------- | ---- | ----------- |
|
||||
| `set_datetime` | `time` | This can be used to dynamically set the time.
|
||||
| `set_datetime` | `date` | This can be used to dynamically set the date.
|
||||
|
||||
## {% linkable_title 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](https://home-assistant.io/components/sensor.time_date/) elsewhere in your configuration):
|
||||
|
||||
|
||||
```yaml
|
||||
# Example configuration.yaml entry
|
||||
# Turns on bedroom light at the time specifiedateutomadate:
|
||||
trigger:
|
||||
platform: template
|
||||
|
||||
value_template: '{{ states.sensor.time.state == (states.input_datetime.bedroom_alarm_clock_time.attributes.timestamp | int | timestamp_custom("%H:%M", False)) }}'
|
||||
action:
|
||||
- service: light.turn_on
|
||||
entity_id: light.bedroom
|
||||
```
|
||||
|
||||
To dynamically set the `input_datetime` you can call `input_datetime.set_datetime`. The following example can be used in an automation rule:
|
||||
|
||||
```yaml
|
||||
# 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'
|
||||
```
