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. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
