Quick end-to-end data-flow proof using only what's on the ESP32-C6-
DevKitC-1 itself (no sensors on the bare devkit -- confirmed via
research: BOOT button, WS2812 LED, no external sensors):
- drivers::chip_temperature_* wraps ESP-IDF's built-in
temperature_sensor driver (SoC die temperature).
- drivers::rgb_led_* wraps the onboard WS2812 (GPIO8) via the
espressif/led_strip managed component (another external registry
dependency, like mdns/mqtt).
- profiles::ChipTemperatureSensor is the first real implementation of
the Sensor interface designed earlier, converting the driver's float
reading to the fixed-point convention once at the boundary.
- transport/mqtt.cpp publishes chip temperature as an HA "temperature"
sensor every 30s, and exposes the LED as an HA "light" entity
(rgb_command_topic) -- the first use of MQTT subscribe in this
project, not just publish.
Added a ChipTemperature SensorChannel (distinct from
AmbientTemperature -- different meaning/range) to sensor.h.
Verified live: both the chip temperature reading and LED color control
work from Home Assistant against the real device.
