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.
148 host tests. Light: static RAM 30,616 B, flash 332,705 B (+140 B).

Light, DimmableLight, ColorTemperatureLight, ColorLight, TemperatureSensor, ContactSensor, Blind,
Thermostat, Lock, Scene, Doorbell and MultiDevice on the 2.0 API: addCapability(row, instance), one
onDirective() handler, the report helpers, ChangeReports from loop(), a deferred answer for the lock.
Wi-Fi is waited for 30 s, then the sketch says what to check and carries on.
examples/README.md has what each sketch does, its limits and the measured sizes for d1_mini: Light
takes 30,616 bytes of static RAM and 332,565 of flash; all 17 sketches build with 0 warnings.
test/test_examples compares the discovery object of every new sketch: 147 host tests (were 135).
The sketches were compiled, not run on a board.
