Input Button

The Input Button helper integration allows you to define buttons that can be pressed via the user interface, and can be used to trigger things, like an automation.

Configuration

The preferred way to configure button helpers is via the user interface. To add one, go to Settings -> Devices & Services -> Helpers and click the add button; next choose the Button option.

To be able to add Helpers via the user interface you should have default_config: in your 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_button: to your configuration.yaml first, then you can use the UI.

Input buttons can also be configured via configuration.yaml:

# Example configuration.yaml entry
input_button:
  ring_bell:
    name: Ring bell
    icon: mdi:bell

Automation examples

The input_button entity is stateless, as in, it cannot have a state like the on or off state that, for example, a normal switch entity has.

Every input button entity does keep track of the timestamp of when the last time the input button entity has been pressed in the Home Assistant UI or pressed via a service call.

Because the state of a input button entity in Home Assistant is a timestamp, it means we can use it in our automations. For example:

trigger:
  - platform: state
    entity_id: input_button.my_button
action:
  - service: notify.frenck
    data:
      message: "My button has been pressed!"

Services

The input button entities exposes a single service: input_button.press

This service can be called to trigger a button press for that entity.

- service: input_button.press
  target:
    entity_id: input_button.my_button
