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.
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
then you can use the UI.
Input buttons can also be configured via
# Example configuration.yaml entry input_button: ring_bell: name: Ring bell icon: mdi:bell
Alias for the input. Multiple entries are allowed.
Icon to display in front of the input element in the frontend.
input_button entity is stateless, as in, it cannot have a state like the
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!"
The input button entities exposes a single service:
This service can be called to trigger a button press for that entity.
- service: input_button.press target: entity_id: input_button.my_button
