It would be nice if there where also support for input_boolean in addition to binary_sensor for alexa‘s doorbell items.
What do you mean?
At the moment I use a combination of binary_sensor template (exposed to alexa) which is listening to state changes of a input_binary. when the doorbell gets pressed a automation rule (which has a event listener) sets the state of the input_boolean to on and then to off.
Therefore it would be nice if the inputboolean could be directly exposed to alexa and would be recognized correctly as doorbell.
