I have implemented device discovery, reporting and the Arm and Disarm Directives.
Does that interface support ChangeReport?
It makes much more sense to report events, such as a burglary event, asynchronously using the ChangeReport mechanism, as one might for an update to a ContactSensor
If that is possible, will Alexa announce the update the way it might a doorbell? Or, can a routine be created in the Alexa app that could be built to announce a contact sensor opening
