With 2021.12 release of Home Assistant the Button entity was introduced.
At the moment this platform / entity type is only available if provided by a specific component / integration.
I would love to see an input_button component / integration,
which allows us as end users of Home Assistant to create button entities by our own equally as we do for input_boolean.
Especially for the use case of voice assistants (like e.g. Mycroft / Alexa) it would be very helpful as they currently do not allow to directly trigger automatons, which means it is necessary to run a workaround of input_booleans which have to be reset as soon as the automation was triggered, to be ready for next trigger.
