An interface without properties says beside its name what Alexa has to know
of it; the library left both out. With a board and Alexa on 2026-09-28 the
discovery of a doorbell was accepted (202), the endpoint was not listed, and
its DoorbellPress was answered with 500 INTERNAL_SERVICE_EXCEPTION.
DoorbellEventSource now always carries "proactivelyReported": true.
SceneController carries "supportsDeactivation", false until the sketch calls
setSupportsDeactivation(true); on another interface the call is refused and
logged. The Scene example says that it can be undone.
